Built a 1/4 wave ground mounted vertical antenna for 30 Meters. There are 4 radials 23.2 feet and the vertical element started off the same but it ended up a foot or two two shorter when I tuned it. At 10.1 MHz I ended up with a VSWR of 1.1 : 1 and the TS690s antenna tuner liked it rewarding me with 80 Watts of CW power.
30 Meters was quite appealing to me...
- Great propagation throughout the solar cycle
- Its CW and narrow band digital from 10.100 MHz all the way to 10.150 MHz .... all 50 kHz of it!
-1/4 Wave is 23.2 feet ... small antennas.
Made 2 contacts ...
So the new to me TS690s is a real gem. Best receiver I have ever had. It goes all the way down to a few hundred KHz and has continuous coverage! I have to beef up the power supply a bit. The radio requires 20 am / 12V and I have a supply that is providing that but it gets quite warm. I have a home brew supply that I think is big enough but I want to burn it in for a bit before using it. I am still in the process up reorganizing the shack ... lots of stuff goes , it will be really cool when I am done.
