Armchair stormchasing & webcam links

I think most Hams are interested in thunderstorms and weather, so here are a few links here if you’re interested.

Met Office Observations
  Might as well start with the UK Met Office.  This link is centred on GB7MB and ‘LIGHTNING’ – but of course you can drag or search any part of the UK and set it for rain or whatever by clicking on the ‘cog wheel’ and selecting the weather type you are interested in. The lightning is live and is triangulated via a very well established network of sensors, apparently.

Lightning Maps
 A European wide real time lightning display.

Blitzortung
Much the same as the European display above, You can’t drag the map like on LightningMaps, but the noise of the lightning as it strikes is remeniscent of an old Geiger counter if there’s a storm on..

Webcam Taxi
Not a storm site, but a streaming video site, with some really great cameras from many parts of the world. There are full video, not flickery updating photographs. Some have sound.

SkyLineWebcams
Much the same cams as above.

Severe Studios USA
No, it’s not a dominatrix site, it’s a North American Storm chasing site.
Live maps from the storm chasers vehicles and full streaming video from inside the vehicles whilst hunting, travelling to and chasing severe weather in North America. 
Some are professionals working for News stations or weather centers, some are science estalishments or groups or individuals.
Be aware that in some parts of the country these storm chasers get into, their 4G or mobile data signal can get broken and disappear for seconds, minutes or completely !

Live Storm Chasing
Similar idea to the above website, seems less busy at times, but it’s a different group and different organization, well worth keeping an eye on too.

UK full video webcams

There are more, but UK webcams seem to come and go regularly, some don’t re-appear,
these are working as on Mid June 2019    Expect interruptions or outages, as most folks don’t take webcams oo seriously any more.

Block it !

Most places you go to on the web now, will almost certainly be serving you adverts, or tracking you, or worse, and this is only an basic article about adblocking, Ublock origin in particular, as it’s the one that gets recommended by security analysts and researchers, and i install it in every browser first thing, i watch a fair bit of Youtube like most of us, and i still see many people complaining about adverts, so let’s go.

Youtube pre-rolls and ads have been around for years, but people really like money by doing nothing, and so adverts have bled their way into Youtube, one of the most high profile sites on the web. 
If You’re ready to watch a video, it’s incredibly annoying to have to sit through some unwanted crappy advert about something you hate, using your bandwidth, electricity, hardware and most insidious, your time.

Adblockers are plugins or extensions for your web browser which aim to stop this, they’ve also been around donkeys ages too, but, like every other bit of software, it doesn’t always do what it ‘says on the tin’ and, sometimes it does rather more… some Adblockers actually bring in adverts to your browser (mentioning no names) as they feed you tailored ads, different to what you may otherwise get fed, and for this, the adblock company gets a pay-off. Ad blockers, not blocking ads for money, sweet, no ?

This last year or two, the one everyone has been raving about is Ublock Origin  by Gorhill.
Actually, it’s not just an adblocker, as Gorhill himself says, it’s a wide spectrum blocker. so It’s a little like a java script blocker and firewall too, and a bit more too. but DO NOT confuse “Ublock Origin” with the similar sounding “UBLOCK” use Ublock Origin(al)

Default settings are, of course, pretty conservative, and try not to break anything too much, there’s always a trade-off between security and convenience, and you’re the only one who knows where the balance is for the way you use the web. The ‘tyranny of the default’ is a problem, and most bits of software – of any description, often benefit from a check through the preferences, in some cases, doing so can often turn a pain in the arse program into a pleasant to use and safer thing.

For me, i put all settings pretty much up to maximum, and if a website breaks, then so-be it, it can be whitelisted, turned off or adjusted until the site functions as expected if really needed.
Ublock Origin is available for every browser, FirefoxChrome, Chromium, Brave, Iriduim, Safari and even Edge although You really should try NOT to use Microsoft Edge Browser even if Microsoft have started building it underneath the bonnet from the Google Chromium browser, but if you must, enable WDAG at very least  before you start fixing it..
If You really want to tighten up privacy with Ublock Origin, go into the settings and enable the extra lists and Prevent WebRTC and for extra privacy i  block CSP reports too, although some people criticized Ublock Origin for being over zealous.




Above: i add extra privacy by clicking the “WebRTC” and “Block CSP”

One of the least discussed, but wonderfully useful things i like about some advert, or content blockers, is ‘element hiding’
where you can either temporarily or forever hide unwanted parts of a web page, sometimes it it *extremely* handy and can get you past some casual pay walls or some only-logged-in parts of some sites or remove bulky or screen wasting photos or guff.


 Here is a rather extreme example of element hiding on the same MSN homepage, these 2 pictures are before and after, i spent a couple of minutes hiding bits of the website – by using the mouse and highlighting it, and  i got rather carried away and deleted pretty much everything !

Properly set up, Ublock origin should stop almost all adverts, even Youtube pre-rolls and in video pop ups whilst enhancing your privacy a little bit more, and it might speed up your browsing too and keep websites leaner and faster, but if you get into element hiding, you can extremely easily break a website (for you and that browser only) in a big way, or you might just hide the video, or login button, so you’d have to go into the ptions in ‘my filters’ and delete the filter lines the program has added.

TDMA – what’s that all about then ?

It’s not always obvious when you get into DMR exactly what makes DMR so ‘special’ and why everyone is jumping on the bandwagon, compared to most other types of digital voice modes, one of the coolest things about DMR over most other forms of digital voice modes is TDMA. that’s the secret sauce.

Conventional FM repeaters, along with older FDMA types work very well indeed, but more can be done, especially nowadays. On an FM transmitter, as soon as you transmit, your transmitters PA (RF power Amp) shoots right over to solidly pumping out 100% constant carrier, this is simple to understand, as indeed is a FM repeater’s basic operation, and we’re all used to and happy with that.
However, one conversation on a FM (or FDMA) repeater generally means that you have to wait until the repeater is free before you can use it of course, so if your message is important, you’re stuffed, unless you have another repeater to make the call on.
Imagine though, a repeater which can carry 2 separate conversations at the same time using the same two frequencies an FM repeater would use ? How ?

The answer, is TDMA, Time Division Multiple Access, it has been around years, longer than you might think, but it’s basically a channel access method – a way of data streams sharing the same channel, (because *everything* is data nowadays) and there are different types of channel access too, but as we are discussing DMR really, we’ll stick to that for now. Most of us, back in the 1990s will likely be familiar of the annoying and somewhat unpleasant ‘buzz’ or interference when your old cell phone was near an amplifier or stereo (remember those?) and the rat-a-tat buzz from the 2G Nokia cell phone you had.. that was a TDMA transmission.

Very basically, and because it’s a little abstract, i’ll attempt to give a ‘duffers’ way of imagining it. I know very little, but there seems to be very few write-ups anywhere on the web about it, particularly for hobbyists or folks who aren’t computer whizz kids, there are many DMR websites and discussions on forums and Facebook, but many others, though thorough and correct, require the imagination the size of a planet and a leap of faith to match.

Here goes, if you were to chop your FM transmitter on and off very quickly indeed, you could also imagine that in between your brief TX bursts, and the snapping of your PTT, that someone else, if just as quick, could send their quick TX bursts out too, on the same frequency in-between yours, no-one would be harmed, but you couldn’t speak fast enough to get your voice over could you ? and neither could the station that you’re trying to talk to.
Now, digital radio takes all your TX audio, throws away what it thinks is unneeded, and compresses the rest.
Now your voice is digital and in squeezed into a tiny IC in your radio, we can do fancy things with it, we can, for instance, break it up into blocks and transmit these blocks in, er, blocks, or packets, –  the quick pulses we mentioned earlier, but faster and electronicaly timed and controlled.
The receiver collects these ‘blocks’ and re-constitutes them, back into a whole lump, like adding water to a 1970s Vesta Chow Mein and you’ve got your audio back at the receiver, albeit after a lot of processing, and of course, you can do this through a repeater or simplex. You can even have two concurrent QSOs on simplex, on the same frequency!

A basic one way QSO through a DMR repeater is pretty simple to envisage,
here’s the first of my (sad and tragic) attempts at basic animation in The Gimp, a open source, free software graphics program, (For Windows, Mac & Linux) which i only found out did animation a couple of hours ago, so be kind to my first attempts !


TDMA – the Secret sauce

As you can see above, transmitting one DMR transmission over a DMR repeater all seems to make some kind of sense, you can see the packets arriving at the repeater, and the repeater transmitting them on.

The interesting bit about DMR is whilst they’re nattering on there, we can start up another QSO on the same repeater and the other QSO will be totally unaware, so, if there’s just one QSO on the DMR repeater, it will be sat idle a good proportion of the time, yet still continue to relay a full QSO on one of the slots, but there’s another slot we can play with, lets look at that.

Slots o’ fun

Above, on grubby animation number two, is what the repeater is seeing when someone else calls through the repeater, hugely slowed down, as for a short time it listens in the (lets call it a ‘gap’) and if it hears any valid DMR on the input at that time, it calls that slot 1, then automatically and without waiting, listens again on the same frequency in the other ‘gap’ or slot, and if a valid chunk of tasty DMR comes in at the expected slot 2 time, well, we will call that slot 2 then, and so it goes, back and forth, many times a second, constantly, until both transmissions stop and it can rest. 

So, to recap, there are now two simultaneous QSOs going on in the repeater, and as we can see, as the repeater is easily hearing both transmissions, the DMR repeater is also sending back control information to your radio, stuff like telling both transmitters when to TX their blocks of data back, all DMR receivers expect to hear packets or these blocks of data, so everybody is happy. Win, Win.


It’s a busy, busy busy job …

Above, in crap animation number three, (I’ll stop soon, i promise) – is a very poor attempt to envisage a DMR repeater in the midst of, er, repeating. Two QSOs are taking place on the one repeater at the same time, neither QSO knows or needs to know about the other QSO,

QSO one (slot 1)  is blue, and QSO two (slot 2) is green, neither know or can hear, (or join in with) the other QSO, they’re both completely independent, try doing that without TDMA.

In the crude graphic, massivley slowed down, the repeater is flashing the colour of the QSO it is currently TXing, it really onl haas one transmitter and one receiver really, but as you can see, it switches between both ‘slots’ automatically and very fast indeed, with the effect that the end user can’t tell. congratulations, because instead of having to buy another repeater, you’ve just got a free one by using DMR.

There are more DMR benefits too, stuff that the FM and FDMA stuff can only dream about,Myself, i like the old P25 phase 1 digital, a mostly American emergency service digital system, but it’s old and FDMA, not TDMA and and has only half the capacity of a these two slot TDMA system, bit TDMA is so important in comms, that P25 ‘phase 2’ is now TDMA, because it makes NO SENSE to invest in a poor propriety digital amateur only mode, or really any FDMA nowadays, unless it’s foe low end or retro fun, it’s a technological dead end street now, technology has moved on, some companies thought they’d lock users into substandard and propriety modes and dropped the ball completely or refused to update, as their cash cow was still bringing in the $$$ whilst other, superior standard, industry wide modes, well supported and still in active development continue to offer future development, rather than just at the whim of some proprietary bean counting exec.. but i digress..

One feature we enjoyed when we started playing with DMR, was to de-key each other .. the locals here are an often cruel and cheeky bunch who used to delight in, lets say, if someone was transmitting for a really long time, and listeners were starting to doze off or get bored, we send a DMR command from our rigs to the Guy who is still in waffle mode – still in TX -and  instantly setting the (surprised) waffling station’s rig back into receive mode – whilst they still had their finger on their PTT !   for a while it was a challenge to not be boring or waffle too much, lest you would be remotely de-keyed in mid sentance !

Such is the fun we had, but alas the tumbleweeds have taken over the hobby and i have to get my kicks by writing articles on MBARS 🙂

Next Article:
“Talkgroups what the bloody hell are they then”

Changes are a comin’

We’re trying to diversify a little bit on MBARS here, Digital radio is just one tiny part of the whole electronics and hobby radio thing we’re all addicted to here, so we’re just mixing it up a little bit, as there’s not really enough happening in the DMR or digital voice part of the hobby to inspire me to pen many articles, the hobby is far bigger than just digital, We’re interested in a wider array of hobby radio and electronics.

I have added more areas, with more specific titles to reflect our other interests, and hopefully you’ll not be not forced to scroll and click around endlessly just to browse this (little) site of ours, with all the areas up the top instead, MBARS is only a 2 man effort, and i do most of the waffling and Quack does all of the Admin. If there are any menus or areas you think we should have, tell us !

So much content is on Facebook nowadays, so it’s a little hard not to be drawn into the Quagmire that is Zuckerberg-world (Giggidy) so please don’t expect a huge quantity of material on here, but we do like the idea of quality, and that is instead, what we will strive for, and that is also why joining is pretty much a slightly more tedious ‘send us an email’ type instead of the more usual email-loop – like you get on most other sites, though that may very well change, but it does keep out most of the spam, so there is method in our madness.

I’m no writer, or journalist, but when i have time (or the inclination) i do enjoy writing, especially on MBARS, but I found the digital radio bias rather restrictive, as i’m mostly a HF SSB Guy really, so I have added up some more categories up on the menu where hopefully you can jump to a particulat type of thing, instead of scrolling around, i found navigating the site a chore myself, so i need to make navigation easier and more straightforward.

Stick with us, and i hope we all can develop MBARS a little more, and take away some of the focus from DMR and cater to the far wider interests that we have, yet we still will stay mostly in the Hobby radio domain…

GB7MB is still on-air, but we use P25 & HF SSB 28.495


The demise of DMR in the area has seen a resurgence of a few of the locals go back to 10m SSB instead.  We have been using 28.495 USB (on and off) for over 10 years now, with a brief flirt with DMR in between when we put GB7MB on air.  Activity is low of course, but is monitored most of the time, so fire your HF rig up and shout up. We are vey relaxed on there and fun, please don’t get offended by the goings-on on 28.495 – instead, just join in,
DONT BE a LISTENER !

The photo above is a MMDVM – a little radio board that sits on top of a Raspberry Pi – those tiny twenty quid computers – and it’s a hotspot for your P25 rig.
You can buy them ready built too,  they work fine. here’s an example.
https://www.ebay.co.uk/itm/UHF-VHF-MMDVM-Hotspot-pi-star-Support-P25-DMR-D-Star-For-Raspberry-Pi-Antenna/253949198976?epid=10025105973&hash=item3b208d4280:g:~csAAOSw61Fb0YNh

After a bit of a config you need a P25 set, they pop up on Ebay and other places occasionally.
you shouldn’t need to pay much above £100 for one, the chinese haven’t yet made a cheap P25 set yet, and likely never will, have a google for P25 digital if you don’t know what it is.

We have a Morecambe bay reflector for P25 and several users, though again, activity is low 🙁

So, that’s an overdue update, just so you know what’s happening (not too much) but feel free to use GB7MB and have fun.

turn your smartphone into a P25 or DMR HT ?

Untitled
Well, You can certainly do some neat tricks with SDR’s nowadays, clever things like making your Raspberry PI transmit AM/FM/SSB and the (slightly pricey) but very interesting HackRF board. I see Fenton Dynamics have been busy lately, they’ve rebranded now from BriCom, and i completely missed them first time around,   Anyway, this device, which is sort of a set of modular clip-on-goodies for your smartphone can magically turns it into a VHF / UHF P25 / DMR / FM / HT is available, and, not that you can tell, but the photo above is of the 2w VHF iPhone 6 version apparently, well so it says in the blurb, all wrapped up in a  Nextpaq case.

For more info check out their August 2015 Youtube posting HERE  and head over to Fenton Dynamics too, if you have a supported Android or IOS device it may appeal to you .. it does far more than what you’d think, with a dual band module, DMR, and P25 modes, analogue signalling like MDC1200 etc, trunking, GPS, ROIP, SOS, alarms etc, and there’s an SDK kit available for third party developers too, and hopefully the apps that will appear as well. It all seems very modular and well thought out, the clipon goodies even has their own mic and speaker and battery, and it’s all neatly wrapped up in a $99 Nextpaq case – with the actual Dxbm modules beginning at $65 it’s beginning to look mildly Interesting. Watch this video or this earlier video which hopefully gives a better idea of it…

Sommerkamp FT 277 ZD sale ((now sold ))

<< now sold >><< now sold >><< now sold >><< now sold >><< now sold >><< now sold >><< now sold >><< now sold >>
Sommerkamp FT 277 ZD MK III  – From a warm, dry, pet free and smoke free home.
It’s got all the WARC bands, and will never ever have been CB’d as far as i’m aware, as i bought it directly off Harry G3LLL, the famous Yaesu 101 Guy who lives locally to us here at MBARS HQ – all that’s changed is that i fitted a FM board, which works, but there is an earth loop buzz on TX (but on FM tx only) i never got ’round to to fixing it as we used SSB !

The mic is a standard taxi type mic and the power lead comes with the set of course. The set has been looked after, RX’s well and TX’s well, the tubes seem good too, i never bothered checking them as the set just kept running fine and never let me down. It’s been kept switched on for long periods sometimes, weeks at a time, (heaters off) and is quite a nice example of the Sommerkamp badged FT 101 ZD mkIII

I will be sad to see it go, it’s like an old friend, but it’s time for me to move on, so here you are.
It’s in used, but working condition, don’t expect showroom condition, and know these sets are about 40 years old.

Best thing is to come and collect it, it’s too damn heavy to post, but if you really can’t get here to pick it up, maybe we can arrange a courier or something, but it’ll likely be pricey, and i’m not even sure i can package it in any meaningful way that would protect it during transport.

Really really, do come and pick it up.

Nice set .. and it will help keep you warm in the winter too.
Come and collect it from Morecambe promenade,

Never mind the fugly, feel the er, quality..

cap

Yes, that’s a real photo of a real chinese electrolytic someone found during a repair.

I’ve not been doing much radio lately, as life kind of got in the way and my interest in amateur radio is somewhat on the wane, but every now and again it’s good to raise your head from out of the trough long enough to taste the cool summer breeze, as i do, i notice a new email from China in my inbox, i wonder if the air is as fresh over in Quanzhou, Yes, it’s another Chinese radio for me to purchase, or not, this time it’s DMR (TDMA) and it’s a Wouxun, it’s the first DMR Wouxun i’ve seen, and the previous FM set whatever it was was, probably wa the best selling (useable) dual band HT after the ‘christmas cracker quality’ Baofengs which hit the streets, so it slightly caught my attention. It kind of goes without saying that the Wouxun i foolishly bought, shuffled off it’s mortal coil after a only couple of years, after randomly crashing, rebooting, reverting to the default mandarin and forgetting everything. dreadful. At least it was a one minute job to re-upload the frequencies back in the set via the USB lead, Worse still was the Yupiteru 7100 scanner which lasted about the same span, then randomly crashed and burned at random moments too, and occasionally forgot it’s nearly 1000 memories. No USB programming there, that got old really quickly, so sold it as scrap, which reminded me of several Yaesu’s having done the same to me since i was a kid SWL, leaving me fed up and with a broke radio, not good enough.

I moved over to Motorola hardware several years ago and have never been let down with their solid hardware (just their occasional crappy DMR firmware) Yaesu have let me down hundreds of pounds for years, and forced me away with bad gear and worse after sales support, so obviously won’t be buying Yaesu or any of the other Ham names anymore, besides which, i think It all looks like it comes from the same Baofeng factory anyway. I love my FT 101 ZD, probably the best HF rig Yaesu Musen ever made, i love the build quality, but i will get rid soon, as i don’t use HF anymore.

Bad experiences aside, i must say I’m quite pleased that the Chinese manufacturers are now making DMR, obviously the quality is not the main priority when they’re knocking these things out en masse, and predictably the programming software is crap too, thank goodness then for Chirp the open source CPS that does a few other (not just Chinese branded radios) and hooray, i don’t have to even use Windows. Thank goodness for that. 2016 huh.

The firmware in the Chinese sets is often poor, but somewhat shockingly, even Motorola screws up firmware releases, the affected Gen2 MotoTRBO Motorola sets crashed and rebooted if you set the DSP and scanlist in certain combinations, and as if Moto didn’t learn by that mistake, the code monkeys at Motorola recently released a firmware which stopped the sets going into transmit mode. Nice job Moto,  but hey, why bother actually testing this stuff ?   I am available as a beta tester, email me for my details Moto.

If you’ve got a Chinese radio you may have the added bonus of fixed, naff, and quiet TX audio too, which seems to be getting solved nowadays, and with some recent Chinese DMR sets, there is talk of slot timing issues which slightly worries some DMR repeater keepers (but which Amateurs measure the slot timing accuracy and rise / fall on TDMA sets anyway ?) – these sort of things should be sorted out, if only they spent as much refining these things as they do with bloody cell phones.. but i digress, there seems to be little evidence slot-timing issues are much of a real world problem at present for Amateurs, my guess is the MotoTRBO repeaters are perhaps adjusting their tolerance ‘on the fly’ in these circumstances, but i’ve no proof..

You do get what you pay for of course, and the Chinese sets and Motorola are of course aimed at 2 different markets, and i hope the Chinese manufacturers one day could open-source their software and get the community to do some of the bug testing and development for them, but maybe the Chinese manufacturers are protecting their own IP (insert: irony) or maybe they’re reluctant to anger DVSI and Motorola’s legal department.  Only joking 🙂 – well,  it’s not stopped them making clones has it, and if it’s not all fake cell phones, and dodgy copies of Windows98 in China, let it be known there were or maybe still are some fake Apple “STOERS” (sic) over there, apparently even some of the employees thought they were actually working for Apple… You can’t make this stuff up can you..  Hopefully the chinese manufacturers will use their famous ingenuity to embrace a emerging market (us lot) my guess is that maybe there aren’t the numbers in the hobby to justify them spending on such R & D..

do know however, that exactly what the hacking / Ham community needs are people like Travis Goodspeed there in this Youtube presentation over at ShmooCon giving a presentation of his now famous firmware hack of the Chinese TYT MD380 handheld.. and there needs to be more of this. This retro looking website might be interesting if you’re interested. Travis’s blog is interesting too, even if it seems he’s not updated it for a few years.

After seeing this brand new shiny Wouxun KG D901  i was reminded of something else the Chinese HT designers should fix, less important perhaps, it’s the look of some of the sets, this bugs me way more than it should, appearances are of course subjective, but to me, the vast majority of chinese radios seem plain Fugly  indeed, some look like they’ve gone out of their way to make them as ugly or as infantile as possible, and some look like they’ve just dropped out of a clown’s arse, stop making them look crapkeep it understated and tasteful, I’m not asking for Johnny Ive  to design the bloody things (i mean, it wouldn’t have any buttons would it ?) but make them look like a proper radio, not something that is so ugly you’re likely to get beaten up for just having one at the next radio rally.

Amazingly this DMR Wouxun has a variable mic gain (must have given the designers sleepless nights) but still, they have 16 channel max scan lists ? – not all DMR sets are so limited, so any arguments about scan speed and missing calls ‘because of large scanlists’ is based on an incorrect premise, that such large lists increase likelihood of missing calls, well possibly, do dealers programme huge scanlists into commercial users systems, instead of only just what they need ?  

Somewhat refreshingly, there are occasional breaks from this ‘tradition’,  as an example, I do like the huge number of contacts you can add to the Connect Systems HT (a few thousand i think it is) – they’ve gone that extra step, which makes it better for masochists who like keeping full contact lists, it seems like Jerry as Connect Systems checked his email, and took notice, and i do understand that there are limitations on what can be done with the hardware and firmware, but it looked interesting and it peaked my interest originally, but i thought the CS700 seemed quite overpriced when compared to what North American buyers were paying, as it’s still a chinese HT, and i refused on principle, I’m an Amateur and i’m tired of pointless restrictions, life’s too short, and if you’re charging Amateur prices, give Amateur facilities.

Some advertising burb even suggest the TYTERA / TYT MD 380 are a copy of the Motorola DP4800, er, no.
I know the TYTs are popular sets, i might even try one, but damn, they need a bit of a makeover, they’re not like a DP4800 other than the keyboard is under the display, the proper place for it. I only just forgave Motorola for making the nice but FUGLY DP3600 and then replacing it with a model that *is* pretty, and screwing the pooch by neglecting to fit an SMA on it – (unless you pay another couple hunded pounds for the blue ATEX model) Yes, Motorola, you suck too, Hams buy your gear too, Moto, and some are about to stop, but to be practical, I require a VFO and other amateur features on my sets now,

know Moto are not consumer Ham type sets, but i’m already tired of the DP4801’s lack of SMA and lack of real FPP ond no VFO’s and real FPP, it’s not even a real option for us in the west, and vendor lock-in is bad for buyers, if only they recognised it, and If i find a DMR HT with the features below, my DP4801 will be on Ebay and i’d likely buying a HT with hackable firmware. for me a useful DMR HT needs:

  • SMA aerial
  • standard 2 pin TRS (jack) or something stronger / more pins features, non proprietry but Moto style.
  • scanlist not limited to 16ch
  • open source firmware / programming software for general hackability, so we can avoid the hateful chinese CPS
  • obvious mic gain & other standard features in radio menu you’d expect to find in any other radio
  • RSSI
  • Full FPP including up/down VFOs and full TG creation without PC. ALL TG rx like the hack for the TYT / Tytera / Retevis MD380 sets
  • doesn’t look like crap, good font and display on set too.
  • rugged

There may be more, like not being overpriced, but that’s obvious, and i don’t mention roaming, though i use roaming on our TAC-9 repeaters, and so think it’s very useful, MotoTrbo compatible roaming would be a sure winner in non-Moto sets, but i can live without it. I do wish the HTs were as pretty as the Moto’s however, below are some of the ugliest HTs i’ve ever seen, apologies if you own one, actually no, but why can’t they make them look less crap ?
