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...

Re: RD-5R Power Calibration
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...

Re: RD-5R won't talk to hotspot, what have I done wrong?
Thank you Colin, Daniel, and Lars. It is working now. however, all of my radio are about 300Hz to the right of the center (+300Hz) and the RD-5R in the problem was 150Hz to the left (-150Hz). I calibrated the -150Hz one to +250 for now to make everything work. Now, I’m up on a new quest. I don’t kno...

Re: RD-5R won't talk to hotspot, what have I done wrong?
It may be that your two radios are on very slightly different frequencies. Most hotspots are excessively fussy about frequency. Do you have a means of comparing the transmit frequency of the two radios? A radio or SDR with a spectrum display would show the difference. You could then use the OpenGD7...

RD-5R won't talk to hotspot, what have I done wrong?
Hi Everyone. I've encountered a weird problem, please have a look at the video. I have two RD-5R. The hotspot refuse to listen to the one on the left. I've check frequency, color code, and DMRID on the left radio, everything seems correct. I don't know what to do next. 73, Charlie. P.S. the synchron...
