A UV82 has come my way as part of a silent key estate.?
It transmits on 2m but not 70cm
I’ve checked the settings to ensure it hasn’t been restricted, tried resetting and reprogramming, still no tx on 70cm. Not even enough to detect on a receiver nearby. Nothing on the display to suggest it isn’t transmitting when the ptt is pressed.
My understanding, which could be false, is that these radios are largely ‘common’ path for their RF - ie only one PA, driver, etc.?
While a bad reactive component may be the cause, if that were the case ( at least if in the PA etc), I’d expected some RF, even if just enough to detect on a nearby Rx.
Has anyone seen this before or have any ideas, please?

Re: Programming software communication issue
This is what i get when i open the file up bud, i downloaded from the group incase the zip was corrupt, but all was fine,, weird one,, lol?

Re: Programming software communication issue
Hi brian, I have no idea why you cannot open the files, I have downloaded them from the group and they open fine for me, see picture, the only other thing i can suggest is go to the radioddity site and download them from there, dont ask me why radioddity have them, lol, go here??then scroll to the bottom of the page, click the DM-1701 radio picture then download the software, inside that software download is also the USB driver, Let me know how you get on bud.?

Anyone know about using a UV5R as an echolink hotspot and specifically what cable are you using successfully with? the UV5R and PC.
I have ordered a K2 cable that is also used for APRS from Amazon after seeing an article on this subject online - but - this cable seems to have extremely narrow audio out when I transmit. It almost sounds like a landline phone going back and out through Echolink.?
Several years ago there was a simple cable setup available that seemed to work well and I was looking to trade notes with someone who has a working setup like this because the cable from amazon doesn't seem to cut it for transmitting back through echolink.
Appreciate any thoughts on this question.

Re: Programming software communication issue
Hi Brian, thats the one bud, the only other thing i can think of is that you have not installed the usb driver for the radio, find it attached,, i'm not sure which one you will need, so try both 64 versions "dpinst_amd64.exe" and "dpinst_ia64.exe", Try one and if you dont get it to work, then try the other, ignore the x86 version as this is for the 32 bit operating system

 I bought this one the other day and it doesn’t get recognized by computer etc. Is that the one u have shown below?

Thanks Don for tips. I will do

This evening, I was thinking of asking you what type of cable you were using.
You say it's Prolific, and that it's recognized. My first thought would be to
ask around in your local club and see if anyone has an FDTI cable, or even a
CH340 type I've used the CH340 cable with 8 "heads" to match with different
radios successfully. I had to search for the driver but it works.
I found out recently that there's also available a PL2303 cable for Windows
systems only (I think it does not require a driver) and a K-Plug cable (also
sold by Baofeng). So there's a plethora of cables out there for these radios to
choose from. When asked, I recommend an FDTI type cable unless the person wants
to be set up to program other brands of radios. In the latter case, I suggest
one of the CH340 cables that have a bunch of different connectors to mate with
multiple radio brands.
Back to your problem. For right now, let's assume your Prolific cable actually
does work and doesn't just report to the OS that it's working. Do you have the
volume control wide open when you're trying to read from or write to the radio?
The programming system uses part of the audio system, and if the volume control
isn't open enough, some have reported that it won't work until you open the
volume control enough for it to allow the signal to get through. Just give it a
try and see if that makes a difference. If it doesn't, try and get a cable from
someone in your local club or another ham you know has the same radio,
preferably NOT one that has a Prolific chip in it. But give this a try and see
if it then works (with the volume control wide open). Also, please let us know
if this changes things for you and it works. Some claim it makes no difference,
while some say it does. I'm inclined to think it does make a difference. I don't
have mine right now but I always have had the volume wide open.
Almost everyone who buys a Chinese HT finds it's not easy to program from the
front panel, so they buy the programming software from RT Systems with their
cable, or use CHIRP with a programming cable they buy somewhere. The cable from
the BTech store on Amazon works (I believe it's an FDTI cable). It's not just
Chinese radios, though. Some Japanese radios are difficult to program from the
front panel.

Re: Programming software communication issue
You are using the wrong cable, the baofeng DM-1701/1702/1801? all use a cable that is passive, there is no prolific chip or FDTI chip on the cable, the programming chip is built into the radio, you will need a programming cable that looks like this. Dont get the DR series radio confused as these do use a prolific/FTDI cable, EG: DR-1801 as you say, you have the DM-1801 so that will need the cable in the picture, just go on ebay and search for baofeng DM-1701 programming cable, you will find plenty on there, not sure if amazon will have them.

Re: Programming software communication issue
Update. Was able to load the 2007 driver that allows the prolific cable to be recognized without error to computer. However, when I go to read from radio, it looks like it’s ready to work and says ‘times out.
Could it now be a problem with radio?

Programming software communication issue
? Hi all. I purchased a baofeng dm 1801 a couple of years ago as a backup to my Anytone. I wanted to add some frequencies to it this week, which I haven’t done in a couple of years, and it won’t communicate with my windows PC. It used to work fine with the programming software. The only thing that has changed is my computer has had Window updates over the years and now running Windows 10. I saw some info about old divers or cables not working on newer Window versions? Any thought on fix? Brian W2BRM

Re: Programming software communication issue
Thanks all. I don’t know anyone that may have older window versions, so will install the driver Colin provided.? Where do I look for drivers to remove?? ?Is that also in remove and add programs?? Would appreciate steps.? I will keep u all posted on results.?

Brian,
I concur with Doug's (VK2XLJ) statement with recent experience with the same issue.
Before Christmas, the workstation I used for programming was working fine. This workstation is Windows 10, but is generally only used for radio Ham related work / logging / etc, so nothing new had been installed (other than a major Windows update coming through)
In February, I ran into USB driver hell with both the Chirp Software and the DMR software, both not working correctly with the comm port. I was fortunate here with both apps not working, and using different methods/drivers of using the USB ports, it gave me
a clue that a Windows update had clobbered the driver. I believe it was the last major Windows 10 update (not one of the smaller patch Tuesday updates)
Main thing was to locate the remove the broken driver, various reboots and re-installing the original working driver(s) - once I did this software was working again, but it was several hours that I won't get back.
Now it is very possible these drivers may be poorly written, or they are not being kept up to date with Microsoft's security or framework requirements (remember many of these drivers hail from 2018 or earlier), so it may not just be Microsoft's fault, but this
sort of issue is pushing more and more people to setup Linux PC's for this sort of work.

Re: Removal of offline symbol DM-1701
Thanks for the response Don, I cant find anything in the manual or online about it, all it says is that it indicates the channel is offline, the cps does not give any clues either, it does change but only when you put a negative or positive offset in the channel info, the blue arrow, the minus and the plus symbol, i'll have a look and see if its something staring me in the face, It's strange as it's only this one frequency, I double and treble checked the slot and colour code and I also get the same info on receiving that frequency on my whistler TRX2, as i say its a weird one because if i program the channel as simplex the blue arrow appears and if i TX the scanner receives it and i can hear, but i can hear a response on my scanner and the 1701 green led lights up but no sound from the 1701. these things are sent to try us,,lol
