I finally got the hardware for the HamClock and installed the free software . It really looks like a labor of love on the part of its creator, Elwood Downey, WBØOEW. I show the ISS footprint,...
I needed some progressbars and collected all the bars I could find and implemented them on an Arduino with 20x4 or 16x2 LCD. There is a total of 10 different bars and here are the two which a...

This was a fun holiday operation from the island of Tenerife with 2.5 - 4 Watts running digital modes, mostly FT8 and some FT4 using a low-band and a high-band QDX. The best bands were 30 m ...
I have now used both the low- and the high-band QDXes daily as EA8/LA3ZA for a period of two weeks without destroying the four BS170 final transistors. Here are some procedures and tips. But...
