WRYS709

PS: This is a Windows 11 issue with the Prolific chip* in that cable, which is probably why they changed cables to the WCH 340 driver/chip BUT couldn't they at least let us know??? hahaha In any event that is a terrific radio and once you get it programable you will enjoy using it too! *NOTE: Some believe that the "Prolific" cable for these radios contained the so-called counterfeit Prolific chip, which was blocked by Prolific's Windows 11 driver; hence the problem! Which, of course, is a good reason to remanufacture these cables with a genuine chip; BUT TELL US it is a different chip!! hahaha

OK: I will write this up in more detail later, but here should be your solution in Windows 11: With the programming cable connected to both your computer and your AT-779UV (turned on); Download the zip file attached to my post below. Extract All Files and Open the folder named: PL2303_Prolific_DriverInstaller_v1_11_0 Run as Administrator the file named: PL2303_Prolific_DriverInstaller_v1.11.0.exe When it offers you 3 options, select the option: Repair - Reinstall all program features installed by the previous setup; Restart WIndows 11 Open your Anytone CPS software and in the SET -> SET COM Menu it should now offer you a COM#; select it. In the Program Menu, select -> Read from Radio. It should now read and download all the settings in your radio, yes? Do a SAVE AS to make a copy of this starting point, in case you have to restore the radio to these settings. Make changes as necessary for your location/repeaters, etc. and do a Program -> Write to Radio to save your new settings to the radio Do another SAVE AS to save a copy of your changed codeplug. PL2303_Prolific_DriverInstaller_v1_11_0.zip

If you compare your screenshot from Hesenate to the list of the files I sent you already in my zip file, you will see they are the same. This is the WCH 340 solution to the "other" cable that apparently you do not have.

OK: I just wanted to confirm that you installed the WCH 340 driver and it still did not work for you, which I have recreated on my computer with one of the two AT-779UV/DB20-G cables that I have (the other one works with the WCH 340 driver); and I called this the "bad cable" even though it works in Windows 10; just not in 11. I should have a solution soon...

I have discovered the problem and am working on a solution now, which I will post in detail later. First, I want to reconfirm with you that you followed my instructions noted above in this post (that is, you used my attached zip file to install the wch 340 driver) and you still received the AT_779 Cannot Open Communications Port, yes? Did you attempt to change the COM in the SET Menu in the AT_779 CPS software and was there any other choice?

FCC rules allow your son to use your GMRS license, including when talking to you on GMRS. Use your GMRS certified radio to talk to your son on his GM-15Pro either simplex or through a GMRS Repeater. Then work with your son to get his Technician Ham License and then you can cross talk on 2 meters and 70 cms Ham bands, if that is important to you.

I was giving you legacy UV-5R programming instructions. Since I do not have the UV-5R GMRS, I will back off for now and let the others help you. Good luck!

It sound to me like you have the "bad cable" for Windows 11; I will keep working on getting a driver for that cable for you. Who was your vendor for your AT-779UV and can you contact them about a replacement cable? In the meantime I will contact my vendor. In the meantime, do you have access to a laptop with an older version of Windows than 11? Do you have any other USB programming cables for any other radios?

Not me! I was listening on Zello but probably napping!

I wanted to buy a UV-5R GMRS just to play with. i just didn’t want to buy two! Use the refund on the DigiRig to buy a genuine Nagoya 771G antenna with the proper SMA for that radio, to improve your range.

OK: gotta go! Hopefully someone else will jump in or I'll be back tonight! Good luck!

Can you link me to the model you purchased online?

Oh, the upper display and not the lower display?

What do you mean by A and B positions?

Daily nap time soon... Did you do these two steps in Freq/VFO mode? Push Menu, Push UP ARROW to SFT-D, Push Menu, Push Up Arrow to +, Push Menu, Push Exit Push MENU, Push UP ARROW to OFFSET, Push MENU, Enter 005.000, Push MENU, Push Exit

Are you able to see the frequency of 467.600 when you transmit and 462.600 when you receive? MON only turns off squelch to try to hear weak signals; you don't need it now.

read my last two posts...

Perhaps, once we are sure you are transmitting on 467.600 and receiving on 462.600 with the digital tone of D023N, then you can go for a ... ROAD TRIP!!!

I think you have the older UV-5R Go to Frequency/VFO Mode and Enter 462.600 Push Menu, Push UP ARROW to T-DCS, Push Menu, Up Arrow to T-DCS, Push Menu, Push UP ARROW to D023N, Push MENU Push EXIT Push Menu, Push UP ARROW to SFT-D, Push Menu, Push Up Arrow to +, Push Menu, Push Exit Push MENU, Push UP ARROW to OFFSET, Push MENU, Enter 005.000, Push MENU, Push Exit Stay in Frequency/VFO Mode and now try transmitting

Is it showing the change of frequency when you transmit? What is Monitor mode?

Then Push MENU again and push UP ARROW until you see MDF-1, then Push MENU, then push the UP ARROW key until you see FREQ, then push MENU again then push EXIT. Now you should see the frequency instead of the Name and see if it goes up to 467.600 when you push the Transmit button

Try this on Channel 25: Push MENU; Push UP ARROW until you see: T-DCS, then push MENU again, then push UP ARROW again until you see D023N, then Push Menu again then push EXIT

Forget Freq mode for now Try Channel 25 outside with a clear view north to Rancho Cucamonga All you need is a good quality USB to K-1 programming cable (preferably FTDI chip). You don’t need a digital modem; those are for ham radios for different purposes Did you program in the Digital DCS 023 tone for transmit?

When you push the transmit button does the frequency change to 46SEVEN.600 (467.600)? That is the correct channel If not, then try Channel 25 DigiRig?
