A 80/40m DDS controlled QRP CW transmitter
- JUMA-TX1 is a 5W CW transmitter for the 80/40m bands. Juha (OH2NLT) and Matti (OH7SV) have had high quality CW keying and a compact size as design goals for this project. No coils need to be wound to construct this transmitter!
A 80/40m Direct Conversion HF Receiver with DDS VFO
- Juha (OH2NLT) and Matti (OH7SV) have designed JUMA-RX1, an award winning 80/40m direct conversion HF receiver with highly accurate direct digital synthesis VFO. The receiver is very compact, because it constructed using surface mount components. No coils need to be wound to construct this receiver!
