Re: Voltage Oddity
Have you done a power recalibration at any time? If you have then you may have set the UHF drive level too high in an attempt to get maximum output power.

Re: Voltage Oddity
Sounds like one of two things,
Your power supply can't provide enough current. It needs to be able to provide at least 10 Amps. The current on UHF is often higher than VHF.
RF is getting into the power supply and causing it to shut down. How close is your antenna?

Re: GPS slow to find location
That sounds normal for these radios. When the GPS starts up it always has to do a cold start. (Because there is no backup battery). A cold start requires the GPS to download the Orbit data from the satellites. This can take a long time if the signal is weak or fluctuating. Keeping the GPS steady can...

Re: HELP! Stuck on Settings Updated screen
It may not be of much use to you but I have found a UK company that claims to have replacement screens.

Re: HELP! Stuck on Settings Updated screen
Bruce has already fixed the button issue, he is now talking about a display issue. Unfortunately the display module will be hard to find. TYT themselves may be the only place you can get one. I have heard of them sending spare displays to people via their Facebook account, but I don't know what thei...

Re: Retained Settings After Flashing OpenGD77 Firmware
Hold P3 when turning on the radio and the press ENT to accept the new settings.
That will reset all settings. Create a new codeplug using the CPS and load it. That will reset all channels.

Re: Retained Settings After Flashing OpenGD77 Firmware
This is normal. cS2 indicates that the timeslot is being controlled by your contact setting. When you define a talkgroup or contact you can also assign it a timeslot. Loading new firmware will never reset the channels. They are defined in the codeplug and that never reset. If you want to remove chan...

Re: Subaudible decoding
Yes, that is quite normal. CTCSS decoders in many radios will often respond to one tone either side of the correct one. This is due to the bandwidth of the tone filtering. When scanning tones the firmware stops on the first one it finds. DCS doesn't suffer from this as two adjacent codes are complet...
