The idea behind this project is that the IC706MKiiG receives on 4m, so there is no need for a full transverter, provided the operator accepts to operate split. It is a KISSAL principle: Keep It Short Simple And Lazy :-)
I decided to replicate G3XBM's simple transverter, TX chain only. I will build it manhattan/dead-bug style using an ADE-1 passive DBM mixer.
The picture shows first components placed on the copper clad board:
- 5V voltage regulator
- canned oscillator @44.900 MHz
- HF input attenuator of about 30dB (50, 680, 100 ohms)
The output of the latter is not a sine wave on a 100 MHz scope&probe, but it swings 0-5V if left floating.
I plan to blog how the circuit grows and how it performs.
