This certainly may not be the last HF radio I have for the 40m band, but it definately qualifies for my first! I’ve ordered 2 of them for <$10 and expect to put them together next week.
Stay tuned as I update this entry.
1st radio is completed, here it is!
Defeciencies include:
1. Crystal controlled – 1 frequency with mild bending
2. Tx/Rx on same frequency
They work!
I built 2 units and can Tx/Rx between the two.
