TG changed in the other channels

Hi OpenGd77 team, I've notice this since day one, but believe it to be normal. However, just to be sure, I will ask it here. If I change Talkgroups on one channel, and then change channel the Talkgroups on that channel changed too. Is this normal? What is going on behind the scene here? The firmware...

Thank you Daniel,

Channel Repeater Slot does nothing

Hi OpenGD77 team, I'm exploring my new Duplex hotspot and step into what I think is a bug. I'm successfully program my hotspot to rewrite everything TGIF to TS 1 and everything BrandMeister to TS2. This include all Talkgroups and PrivateCall (including 7 digits talkgroups on both network). I've prog...

Re: Mobile radios

TYT MD-9600 and/or Retevis RT90. They are the same radios, just different brand.

Re: RD-5R Power Calibration

It may be that your radio cannot go lower than 1W. Individual radios vary greatly so that is a possibility. You can check by going to the 1W Calibration and reducing the adjust level to zero. That is the lowest power that can be achieved. Also to calibrate correctly you should do at least three adj...

One question, as I don't know this meter, is it capable to display accurate values below 1W ?
That might be the problem. The specification said 0.1-120w, but I don't really know. Do you have recommend meter? Something below $100? Digital preferred, but analog is ok.

Re: RD-5R Power Calibration

Hi Daniel,

I'm trying to calibrate the power output, but after calibration I can't go under 1 watt. Seems like the radio can do lowest at 1 watt no matter if I set it to 0.75/0.5/0.25/ or 0.05 Watt. Please have a look at the video.

RD-5R Power Calibration

Hi All, I'm trying to calibrate the power output of my RD-5R. I've read through the manual and found this. The power level for a given user setting value, varies considerably from radio to radio and will vary depending on battery voltage and transmit frequency. The power level will also vary dependi...
