This project originates from 90ties. I build it in 1998 from M. Vidmar hand drawn plans. It still works OK.
If someone wants I can upload original articles from VHF Communications.
Somewhere I must have a set of PCBs for this project.

Hi all

Today you don't have to mass with microwave design (well almost not...) to obtain microwave signal source
TI & Analog device have new line of synthesizer's who include an internal VCO (no external components needed) where you can program almost any frequency in the range of 400 to 4000 MHz
(TI - TRF series and analog ADF series)

All the best
