Description

This is a strange issue that I've tried to resolve for a long time, off and on, but the Baofeng UV-6 (not to be confused with the UHF-only UV-6R) appears to set something as a RX tone for each repeater channel. The strange this is that it only appears to do so for channels that have an offset. On simplex channels, it doesn't do this behavior. Using another HT, I went through each and every single CTCS and DCS tone to see which RX tone might be being set when none was programmed, but couldn't receive audio using any CTCS or DCS tone. It may be setting garbage for this value. The consequence of this issue is that this particular HT, the UV-6, can only be used with repeaters that TX with a tone as you can simply just set the channel to have a RX tone for that particular tone the repeater TX's with. However, since most repeaters don't TX with a tone, the UV-6 won't be able to output audio from them. Note: This may be a hardware or firmware bug. I've tried three different UV-6 HT's and all three exhibited this behavior.

My UV-6 was a loaner which is long gone so there is no way for me to reproduce this.

Try programming a repeater channel with the OEM software. If the same thing happens, then this is most likely a hardware/firmware issue and there is probably nothing to or with CHIRP to resolve it.

If the factory software can program a channel without the issue, attach a CHIRP Radio Images (*.img) file with both a "bad" channel and a "good" channel that can be compared in order to figure out what is different.

Hi jim! I should've thought of that and known you'd be here.. ;-)

Ok, I had to scour the web to find the OEM CPS, but was able to find it. Unfortunately, it does the same thing with the OEM CPS, so probably can chalk this one up as a legit firmware or hardware issue. Unfortunate as this is would make a decent cheap dualband screenless HT. Oh well.

If anyone comes across this and wants the OEM CPS, I put copies at:

Thanks again See ya at our usual place Jim. :-)

If I recall, the UV-6 is basically a UV-5R with the LCD and keypad removed. I uses the same code by just hiding the settings that are dependent on the display or keypad. So it isn't to hard to reason that it is some sort of hardware/firmware bug in the radio. But it was worth checking just to make sure (it would be the first time I had to eat crow).

Thanks for checking. I will close the issue. If someone happens to come up with a workaround, it can be reopened.
