Three that got away

Tidying up my workbench, I realised that I have three other projects on the stocks:

• an S-Band downconverter from Bob Seydler K5GNA that I want to try out on AO-51
• a signal source to help check that the downconverter is working - I have my eye on a design from Bertrand Zauhar VE2ZAZ
• a "huff and puff" VFO stabiliser from Cumbria Designs that I bought to try with the homebrew VFO project
  

Both of these are at the back of the queue. I just started the homebrew VFO. More on this soon.
