OpenGD77

I went ahead and updated to the latest source which includes some new contacts selection stuff, and fixed the issue with the Digital "Monitor" between Single and Double slot listening. I also added another setting for 10mW power levels. How much does it actually put out? Hard to say! But it's pretty...

I reverted the code for now. This update will work. This update also includes the new power settings. Results may vary for those power levels.

не работает фильтрация по TS (double не работает) I will look into it. I changed it so left arrow selection would be "Single" and right would be "Double". Something could have happened. Thanks for the post. If I see it doesn't work, I will post a fix. Thanks! Update: You are right, it does not work...

Calibration across radios is certainly different. I took the stock calibration from the new source code, and it tossed my low power levels off a bit. 50mw was 150mw. But I suppose that is expected. I also noticed I get 4.5 watts out on the 3 watt setting. I haven't done any calibration in the CPS ho...

50mW two yagi antennas were sufficient for communications at a distance of 20 km (446MHz). Very useful options for me

Very awesome. I was able to do 27km with 50mW on VHF to my repeater which isn't line of sight. QRP is fun!

250mW has worked since I moved to OpenGD77, I'm never more than like 30 feet from the hotspot generally, so it's not exactly DX but it's just a Pi-W-Z sitting on the desk with the junky antenna that came with the MMDVM, seems fine. For all I know, maybe 50mW is outputting zero on my radio, I have n...

Interesting, my hotspot doesn't hear anything on 50mW, even close. 75mW seems fine. Even across the house. Like 50mW isn't doing anything at all. Messed about a bit more, 50mW if the HT is literally touching the hotspot is heard, signal seems good, S9+30 but anything a inch or two away, nothing. 75...

I went ahead and added the support for the extra power levels down to 50mW on my builds. I added 75mW and 100mW to it also. They are *rough* estimates. My meter doesn't do well below about 70-80mW, so it's a lot of guess work, but should be fairly close. Download from here. http://www.opengd77.com/v...

Updated to provide 3 more power levels of 50, 75, and 100 mW. As well as other minor changes.
Your mileage may vary with the 2 lowest settings. Some radios may output on the dot, or basically nothing.

I did some more tests and have slightly adjusted the parameters (scaling factors) for the 2,3 and 4W as well as the fixed offsets I use for the 250,500 and 750mW values. One thing I have noticed is that the battery voltage makes a big difference to the output power. My battery was at 100% and the b...
