Have had a G4TWJ sequencer donated to me and wonder if anyone has any ideas about it. Based around an LM324AN Quad op amp and 4 x D620A npn as output drivers. Circuit diagram would be helpful Thanks -

Hi all, I built quite a few downconverters for multiple microwave frequencies in the past. One problem I seem to be having with it is that I appear to have a output passband with a lot of ripple on it

Who's doing what this weekend? just so I know what to put on the mast. 23, 3, 9 or 3Cm?. Lets have your comments.
