Between November 2020 and February 2021, I reached 85 DXCC. For DX I used a 2xIRF510 power amplifier with 30 Watts output.
First time I had a simple dipole but I felt that need a better dx antenna.
This vertically polarized 40m loop is a really amazing antenna for Rx and Tx also.

TNX FOR CONTACT 73 & DX!

During the first lockdown in 2020 I decided to build a small trx to 40m and try to complete 100 DXCC in the winter season.
It almost succeeded:)
My goal was to develop a minimal single band CW transceiver with as few parts or modules as possible.
Download schematic
This radio has two double shielded pcb. I tried to separate the digital and analogue components. All noise sensitive wires are thin shielded AF cable.
PCB is made with cnc milling machine.
I used
Autodesk fusion 360
for the design. Thanks for supporting personal use for hobbyists.

I updated digital section that it is able to use 4 bands.
Press TUNE button short time that change band. A6 and D8 (you have to use mcu hw reset that D8 becomes free) pin are a 2 bits BCD band data output.
