Re: New GD-77 / GD-77S / RD-5R / DM-1801 Beta

Hi all. I have a TYT MD9600, a MD380UV and a Baofeng DM1801 with the latest version of Opengd installed, the version with the new option "Force DMO". The three transceivers have the same behavior the first time they are powered on. When you are on a duplex channel with Force DMO option set to NO , ...

I am not sure how to do this. I have a Tiny SA and a NanoVNA.
Neither device can accurately measure the frequency

Try manually tuning to plus or minus a few hundred Hz using the VFO

Re: Choppy DMR Receive Please Help!

Hello all! So far I am really liking opengd77 but lately I have developed an issue. I am listening to a local DMR repeater and the audio is choppy. It is persistent.The signal is strong, from s8 to s9+20 or more. I searched the forum and found a bunch of post on how to tune a hotspot but nothing mu...

Re: TYT MD-2017 Alpha 2.2

Well I do get the above behavior, and it's weird. Also changed to voltage display and I can see it drop, but if I measure with a multimeter it stays the same. Did further tests with a 7.6V external power supply strapped to the battery terminals (actual battery removed) and I get the following consu...

Re: TYT MD-2017 Alpha 2.2

has anyone noticed high power consumption with the opengd77 firmware? at 50mW TX power a 10seconds QSO draws 4% of the battery, that is not good. GPS is enabled, but disabling it does not make any significant difference. LOL. So you are saying your battery will sustain transmission for 100/4 * 10 s...

Re: Power Calibration

Taking advantage of this thread regarding power calibration. Is there any way to calibrate the power values of 1W, 750mW, 500mW... on the TYT MD-9600? No. The official calibration data table, which we also use, only contains 4 values per frequency band. 5W, 10W, 25W and 40W. Values below 5W are ext...
