OpenGD77

For those in the US the MD-9600 is in stock at R and L, link below https://www2.randl.com/index.php?main_page=product_info&cPath=14_300&products_id=73770 They also have it for $10 more with a decent 30amp power supply. This is the way I got my first MD-9600 a few years back. This is seems a good dea...

I have my QTH in Tazewell, TN (NE TN) and I trave I-81 through SW VA. As always no promises about how it will do for you but my MD-9600 works just fine with it. Remember to set your OWN DMR ID in the CPS in the the DMR ID and Callsign section. Hopes this helps. It has both Analogue and DMR repeaters...

Installed and tested. Working great.

Thank you

Loaded this newest FW for the MD-9600. Seems fine until I try and use the D key on the mic for 'latching' and then adjusting the power level. Seems that the D key no longer latches on a Long Press. Am I missing something or did something change in the Key configuration / assignments? AA3RP I think ...

From a thread in the MD-UV380 / RT-3S radio section, VK3KYY stated Various people have tested these radios under laboratory conditions, and Rx performance on the RT3S was measured to be the same on UHF on the GD77 and RT3S. However, IMO the RT3S RF hardware design is inferior to both the GD77 and DM...

see this post https://opengd77.com/viewtopic.php?f=7&t=2279 None of the current production Baofeng '1801' radios will work with the 'Open' Firmware developed and supported here. The current production radios are being labeled DR-1801UV as yours and I have seen DM-1801v2 and other labeling. The botto...

BTW. Power calibration on all UV380/RT3S radios seems quite wrong. By default the 5W / High power setting seems to be outputting well in excess of 5W on most people's radio I plan to make a calibration screen for the firmware, becuase its impractical to modify the CPS to handle the different calibr...

ok, for what its worth here are the measurements for my RT3s , and my DM1801: RT3S: VHF 146.000Mhz , TX 6.33W rx sq open 0.2 uV ( -121dbm) loss of signal 0.134 uV (- 124.5bdm) UHF446.000Mhz, TX 5.3W rx sq open 0.25 uV ( -119dbm) loss of signal 0.23uV ( -119.8 dbm) DM-1801 VHF 146.000Mhz , TX 5.3W r...

I have GD-77, DM-1801 (original), and RD-5r HT radio's. The GD-77 and DM-1801 are basically the same radio hardware wise, with some difference in the external key arrangement, and the RD-5r seems to be a DMR radio put into a UV-5r shell using all the same batteries and accessories. I find no noticea...
