So after a couple of years I logged into my eQSL profile again. I ran into this as I was starting to use FT8 again with WSJT-X and JTDX, two fantastic pieces of software.
Surprisingly,as I logged in after many years, I found many QSL cards in my inbox!
So I took the effort to upload my German License and got admitted to the Authenticity Guaranteed Program within one day.
I ordered this radio as soon as it became available without any expectations. The price was so low that I did not expect much. Also as I already had a RT-82 I did not really need it, I was just thinking if the radio works it would be a nice dual-band spare radio. Boy, was this radio a surprise! Its a real dual-band radio, a real Tier-II radio, it performs really well (good receive performance, even with the stock radio), it is a lot lighter and slimmer than the RT82, even thinner than the MD380. Also I like the display of the GD77 better than the flashy display on the RT82. And the GD77 doesn’t have a stupid track-ball 😉 The GD77 has a decent Promiscuous Mode in the current firmware (just enable the monitor function). The great thing is that Radioddity is constantly improving the firmware and the CPS software, so you’ll get pretty regular updates (you can find all this documented on the Radioddity Facebook groups).
The only downside today of the GD77 compared to a RT82 or another DMR Radio with experimental firmware is that the GD77 cannot store the full DMR database (user.csv).
But.. today the GD77 is the radio I use most of the time and I’m ordering a second GD77 soon.
Last month I did progress nicely on building my BITX40.
I’ve ordered a nice case from India (https://amateurradiokits.in/product/bitx3b3c-fll-case/) and added a s-meter I bought at the HAM-Fest in Friedrichshafen.
The result is quite nice!
This is a nice site of DL4YHF on all the TYT MD380 / Retevis RT3 modifications.

This is a great BLOG article on using a RaspBerry PI for HAM Radio:

F5UII wrote an excellent article on how to calibrate a MMDVM repeater. Both with a spectrum analyzer or with a simple (RTL) SDR USB stick as an alternative to a spectrum analyzer. Great stuff, please have a look;

It took me about an hour to build the BITX40, this is a really fun little project. After the first installation I updated the Raduino from Version 1.01 to version 1.10

This adds tons of new features, all the features can be found here;

I am still running the standard hardware, I will add the following hardware extension soon;
This is a cool project, I like all the experimenting and extending that is possible.
Thanks and 73,
