Commtel COM204 [Realistic Pro 43]

You can have all the new radio scanners you want. I've got a few Quansheng's and Baofeng's etc. But if you're someone who's owned lots of older scanners over the years, and at some point sold most of them, the temptation sometimes comes back to go out and buy some older radios. The nostalgia can be strong. And there's something different to using an older scanner. It feels a bit more special. A bit like a digital camera that can take 1000 photos on an SD card Vs a film camera that takes 24. That's what's happened to me lately. The nostalgia came for me. I ended up buying two older scanners I've never owned before. Those are, a Commtel COM204, which is basically a Realistic Pro 43 with a different speaker grill, and a Yupiteru MVT-7000 which I might write a little review on soon.

The camera flash makes it look like the radio is in bad condition. But its not!

Anyway, this is just a quick post about the golden oldie Commtel COM204 [Realistic Pro 43]. My first impressions. Despite how popular the the Realistic Pro 43 was, and still is, I've never owned one. I'd heard about how good it was and have recently been reading about it and watching video reviews. So I seen this Commtel 204 up for sale on eBay and thought I'd send the guy an offer. He accepted, so I got the radio really cheap. But he took ages to post the radio.

Well it arrived and had batteries inside so I was able to turn it on and get scanning straight away. Condition was overall very good for a 30+ year old scanner. There are a few problems linked to this scanner. The main one being the keypad buttons can go bad and stop responding. But I think this is only after many years of use. I think / hope my one will be good for a few years yet as it doesn't really seem to have had much use. The keypad responds well.

Using the scanner and I can see why so many people hold it in such high regard. It's considered one of the best older scanners. It has 200 channels to play with. Here are some good points that I have found so far.

Very nice scan speed. It has hyperscan, so scans fast. Has a good receiver for such an old scanner. And the receive is very tight and solid. No fake signals, no hissing / stopping in weird places were there's nothing [unlike the Yupiteru!]. Just a really nice well balanced scan.

AM / FM button. This is great for people who love airband. And this radio is well known for its very good air-band reception. One press of this button swaps modulation from AM to FM. I have no use for it though really as I'm not into air band.

Very easy to use. It's so easy to save channels, perform a channel scan etc. Compared to some scanners out there, this is one of the nicest and easiest to use. There is one little flaw, though, that I will mention below in the no-so-good points.

Great squelch. The squelch is very well behaved on the Commtel COM204. No choppiness like on my Quanshengs. This is because a manual squelch can be set lower. Whereas a modified Quansheng, with a digital / on screen squelch has a lowest setting of 1. But this is still too high for a lot of signals. As a result they come through choppy / broken. I did find a fix for this. Another method is to just disable the squelch altogether when you have a signal that you want to listen to for a while.

Good speaker. Some people have said the speaker on this old scanner isn't great. But I think its actually quite good for an older receiver. I mean, some of the old scanner that are held in such high regard, like the AOR 8000, has a terrible speaker. This one is much better.

Well built. This radio feels great in the hand. Especially with batteries in, which gives it that extra weight. It's a fairly small but sturdy well built older scanner that seems like it would take some knocking around and keep on working.

No so good points


All scanners have them. With this one, firstly the light. The light is terrible. It's like the little amber light you get in those early Casio watches where it just lights up the side of the screen. 

Second, but a bit unfair. The keypad doesn't light up. So for people who use this radio in dimly lit areas, like me, it can be a bit annoying.

Third. The beeping. The beeping is a slight annoyance. Each pressing of a button on the keypad is followed by a beep. This can not be turned off without modifying the scanner. That mod I believe requires the opening of the radio and doing to soldering work. So there's no way I'm doing that! Also, the low battery warning is also a beep with the screen flashing on and off at the same time.

Fourth. It takes 6 AA batteries. This is a world away from the newer radios, like the Quansheng K6, that have a lithium Ion battery that lasts ages. Charge it once and it that's it. It's good for easily a week or two with my usage time. And even after around two years of use, they are still going strong. And also, with some of the older radios such as the Commtel, they use a battery holder. And they can be hard to find for sale if a replacement is needed.

Fifth. One thing I can't figure out with this radio, is how to perform a manual scan without saving the frequency to a channel first. I don't think it has this feature. For instance. If you just type in a frequency in manual mode, it won't let you continue after the first 3 digits have been typed. It thinks you are trying to go to one of the 200 channels. The only way I could input a full frequency was in program mode.

And with that you have to save it to memory. After that you can press the "direct" button and start manually scanning the frequency range starting from the saved channels frequency. From there its plain sailing. But I suppose this is just a quirk of older technology. If I'm doing something wrong, and someone knows how to do this without having to save to memory or start a manual scan from a channel, post a comment below.

Sixth. Mono headphone jack, which is a sign of the times with the early to mid 1990's scanners. But there is a workaround. Just put the headphones in your ears, plug them into the 3.5mm jack on the scanner and pull the headphone connection jack out a little bit until you find the sweet spot where you can then hear sound through both ears.

Am I glad I bought it?


Absolutely. Despite a few minor niggles that are common with old scanners [they all have a few things] this radio is definitely a keeper. It's a solid radio. I really like it. I can live with the poor light, the 6 AA batteries and the odd programming annoyance [which is easy to get around]. This is what makes it an older scanner. 

I have to give it a lot of credit, it's over 30 years old, and really there still isn't that much bad to say about it. Still works great. And no doubt, It's good points far outweigh the few bad points that were really [mostly] just how things were 30 years ago. A bit more tech-primitive. And in many ways I prefer that. I've been using up to date stuff for a while now, so It's been great stepping back in time using this scanner. 

If you're looking for an old school scanner radio that has a fairly wide frequency range: 66-88MHz, 118-136.975MHz, 137-174MHz, 220-512MHz, 806-999.9875MHz, has excellent airband, and excellent receive in general, give this one some serious consideration.

F4HWN Talks About Quansheng Version 2

Armel [F4HWN] Talks About the limitations of the Quansheng radios with Version 2 installed and how they can't be upgraded with new firmware. Watch at the following link. Video is in French. I would have embedded it here, but watching the video on other sites has been disabled by the video owner for some reason. If you don't understand French, the translate function on YouTube works well at subtitling [CC] this video. So basically, if you are wanting to buy a Quansheng K5 / K6 or UV 5R Plus to upgrade with modded firmware like IJV, F4HWN or Egzumer, do not buy a version 2 model radio. The microcontroller is different. It went from V1: MCU DP32G030 to the new V2: PY32F030.

quansheng_v2_v1_V3_flash_mod

There is also a version 3 available now which I believe is also OK to install firmware on. So if buying to flash, get either V1 or V3. If you're not bothered about upgrading, buy any version you want. Some rumours say that Quansheng have adding this unpopular feature with V2's because some people have been returning their radios that are V1 because they bricked [broke] them trying to flash them and the return rate was high. I'm not sure this is true. I think its just someone's opinion to be honest. There's never been a problem before with this, not even when the modding of these radios, which has now been going on for years was at its absolute peak. So who knows.


New Browser Based CPS For OpenGD77

First off, I think its a great idea. Makes things much easier in many ways. Yes, there is a new browser based CPS for OpenGD77. I happened to stumble across it and thought I'd give it a go. I used it with my Baofeng DM-1701 DMR [using the STM32 option]. It also works the Baofeng 1801 [select the MK22 option]. And while it did work just about well enough [it did not brick the radio], do be aware that it is very much in its early to middle stages of development. BETA as things like this are usually called. Read my experience below on the good and bad with this new CPS. If you don't want to read and just want to go and check it out you can find it here: https://grid.radio/opengd77/


New_Browser_Based_CPS_For_OpenGD77

Didn't work "out-the-box" for me [using Windows 10 - 64-bit]. I needed to install USB drivers - the WinUSB driver and software called Zadig. Once installed it did work with the Baofeng 1701. This radio needs the STM32 option selected [dropdown box at the top]. I added repeaters, zones and edited channels with no issues. But problems did start to arise.


Messed up my genuine OpenGD77 CPS

Although fast forward to when I'd finished using this software from grid.radio and fired up my original CPS software. It quickly became apparent that the original CPS would not work properly anymore. It now had a problem. There was a driver / software conflict. This took quite a long time to sort out. I had to uninstall and re-install drivers, restart my computer etc. In the end I got my original CPS working, but that experience has made me very hesitant to use this browser based CPS again out of fear that it will do the same again. And, based on this experience, I'd rather have the original CPS working than this one. Read more below for more reasons why.

OpenGD77_CPS_Browser_based


Can't install GTM themes


One good thing about this software is that it does come with a theme editor, and that theme editor has a nice selection of GTM theme files available to import / export / add straight to the radio etc. Many of the themes look very similar to what I've found online at the OpenGD77 forum that could not be downloaded anymore. I've talked about that here not too long ago. Problem is, when trying to install straight to the radio, it asks for 3 separate theme files.

CPS_with_GTM_theme_files


Upon adding theme files to each upload box and trying to write the theme to the radio, it crashes half way through. The radio says its writing to the radio, but just hangs forever. I really thought I'd bricked my radio at one point, but I turned it off and back on and it was OK. My old theme was still installed as if nothing had happened. Needless to say, I didn't want to try that again. But I did, and ended up with the same result. But at least the radio was OK once turned off and back on.

The best way to install the themes was to export them, save them to your device, then use the original OpenGD77 CPS to import and install them. The original CPS installed the themes with no problem at all. But yeah, the process was quite long winded and annoying.


Can't mass delete channels, contacts and repeaters


Be very careful when adding channels, contacts and repeaters. I was like a kid in a candy shop. I seen how many contacts, channels and repeaters could be added using a few clicks of the mouse, from the UK and worldwide and thought yeah, I'll add them all, this is exciting. Only to realise after that I didn't really want or need that many, and after about 20 minutes wanted to remove most of them.

My radio felt so cluttered with contacts and channels that I had no use for. I wanted them removed. So I tried to mass delete them all using the grid.radio CPS, only to discover that there was no option to delete them all. No "select all" box, nothing. So I started deleting them one by one. Then I thought, forget this, it's going to take weeks. So I fired up the original CPS and mass deleted them all there no problem. Other than the USB driver issue talked about above which broke the original CPS' ability to work, this was the most annoying problem with this browser based CPS.

The last issue was the constant need to press "connect" again every time I wanted to change something. It was like pairing was instantly lost or something. And there was a few times when trying to read / write to and from the radio that I never realised that it needed to "connect" again, like 5 seconds after the last time I pressed "connect". This was a constant issue. But I got used to it after a while.

I'm sure the developers will sort these bugs out sooner or later and add the mass edit / delete option etc. And will probably iron out the other issues mentioned here. But in the meantime I think I'll stick to the original CPS. It's not perfect, but it is less buggy and easier to live with than this one is at this stage of its development. A good attempt though. And it could be great in the future. If you're feeling brave give it a go. https://grid.radio/opengd77/

2-Pin "Kenwood" To 3.5mm Headphone Jack

This lead isn't actually Kenwood branded, but this 2-pin connection type is commonly referred to as the 2 Pin Kenwood connection. Well, it has arrived. I've been after one of these for a while now to test on some of my radios. Having used the hands-free style, one ear headsets, where sound is obviously only coming through one ear, I have wondered whether the 2-Pin "Kenwood" style connection to 3.5mm headphone jack cable when used with normal headphones would be mono [sound through only one ear] or stereo, sound through both ears.




Because many of the older scanners were mono, and I've never actually tested new radios from China in this way. I'm happy to report, that both the Baofeng DM-1701 (here) and the Quansheng K5 / K6 (here) emit sound through both ears with this cable connection and sound really good. Headphones are definitely better when using radios that are DMR [digital], as it can be hard to understand what's being said sometimes from the normal speaker. It's not like analogue. So yeah, this cable makes things easier.



Although, do be aware. I have noticed that there is a sharp click / popping noise each time a signal is received, and with each response. I don't think this is anything to do with the headphones themselves, or this lead. I think It's built into the radios. When a connection is made, the internal clicking / popping sound is instantly heard through the headphones. I'm not sure if there is way to turn this sound off [if anyone knows post a comment below]. I doubt it can be turned off to be honest. The clicking / popping isn't overbearing, just a slight annoyance. it is tolerable.

I bought mine from AliExpress, but they are also widely available to buy on Amazon here.

Black ABBREE Better Than Telescopic CB

From using both the black whip and silver telescopic antennas by ABBREE for 27MHz UK CB for some time, I can say without a doubt that in my experience the black whip is better overall. It sounds better and picks up signals from further away. One example is them both picking up American CB chatter from the UK and comparing both antennas. The black whip seems to pick up the repeater better and can pick it up those signals much clearer than the silver telescopic. And I've tried the telescopic at all lengths, fully extended [it's over 50 inches!], half way, fully retracted etc, and it still couldn't best the black whip.

CB_27mhz_antennas_comparison


It's the same result with the local CB signals in my area. I have compared both antennas and the black whip is just better. Clearer sound, can pick up feint signals better etc. Don't get me wrong, the silver telescopic is a good antenna @ 27MHz, not bad at all. But in comparison to the black whip, it gets beat every time. This is just my honest findings and opinion. I have no axe to grind by saying this. I know many people love the silver telescopic. When purchasing, I bought the black whip first, and bought the silver telescopic a few months after because I thought it would be much better than the black whip. But I was wrong.

I personally think this could come down to the materials the antennas are made from. Any telescopic I've ever owned has always been good, but always more hissy and had less signal clarity than my other antennas that are not fully metal. Perhaps its the cheap metal used. I mean, what are they made of, thin aluminium? Vs the plastic coated antennas that have a mix of different metals inside, such as copper, more solid metals etc. Telescopic antenna's are also hollow inside, so maybe that also has something to do with it. I'm no expert, but that's what it seems like.

+W- Power Setting On The Baofeng 1701

The +W- setting On the Baofeng 1701 DMR radio is the highest transmit power setting available, and its only meant to be used in an emergency as I think it can damage the radio if used too much. Problem is, if messing around with the radio it's quite easy to accidently press the right [or wrong] buttons to enable this setting. I've done it several times now. The second problem is how hard it is to reverse the +W- setting back to a normal 1 Watt, 5 Watt or whatever you want to use. Or at least it seems really hard when you don't know what to press. 

+W-_Power_Setting_On_The_Baofeng_1701

I was there pressing every button combination under the sun and still couldn't figure out how to lower the power. It's actually really easy when figured out. Please note: this is for radios that have OpenGD77 installed. The process will probably be a little different with the stock software.

How to reverse the +W-  power setting On The Baofeng 1701 [with OpenGD77]


Press and hold down the lowest button on the side of the radio. While holding the button down press the P1 button on the keypad to lower the transmit power. I don't transmit on my radio so I have it on the lowest setting, which is 50mW. If you want to higher the power you can either press and hold down the P2 button and it will go up in increments on at a time, or you can press and hold down the lowest side button while pressing the P2 button.

Do note: the only way to reach the +W- setting is through pressing and holding the P2 button alone. Holding down the side button while pressing the P2 button to increase the transmit power will go up to the regular highest power setting, which is 5 Watts.  

More how-to's for this radio. If you want to know how to find save and scan new frequencies with the DM-1701, you can read about how to do that here.

GTM Theme Files For The Baofeng 1701

I know I can make my own now that I have the programming cable and CPS software for the Baofeng 1701, but sometimes the colours don't match what I have added to the colour palette. They are vastly different for some reason. Maybe its a glitch with the software, I don't know. Anyway, theme files can be shared among users. The files are in .gtm format, and some users have made some amazing colour themes for the Baofeng 1701. And the .gtm files are very easy to add to the radio with the software.

Problem is, one of the only places where users have openly shared the majority of these themes, which are technically free to download, has been left unworking due to the owners claiming that people / bots etc have been hacking the website, and they have disabled important parts of the website because of that. So no one else can register to the website, and the themes can't be grabbed / downloaded.

GTM_Theme_Files_For_The_Baofeng_1701

Pictured above. A screenshot from the thread "Post your creations here" on the OpenGD77 forum, where nothing can be downloaded and no one can register to the site anymore. The colour theme above reminds me of the old Ceefax screen which used to show on TV in the UK back in the day.


Despite the themes being visible as thumbnails with download links on the site. As mentioned above, that website is the OpenGD77 forum. As a result, none of the shared .gtm theme files at the thread linked to above can be downloaded anymore. I'm not sure if users who are already registered on the forum still have access to the site and are able to download files. I did manage to find 3 other gtm files online but that's it. The best ones are on the OpenGD77 forum.

Does anyone know of a website or download link that has all the .gtm theme files in one place. I could not find one. The files themselves are tiny in size, literally under 1KB. So a full download of all the files on that forum would probably be less than 1mb to download. So frustrating to be able to see them all in the forum thread and not be able to use any of them.
