VHF Sweep Oscillator and wobbulator
In the Test Equipment section Bazz was making enquiries re a suitable interface of a RF wobbulator and a scope.
I knew I had made a piece of equipment a few years ago to tune my 4 pole 2 metre filter. I dug out the schematic to realise it was May 2000.... and my early schematics and pcb arts had been lost, except for the hard copy. I have redrawn it to my DIPTRACE files and I show it below.. some may find it interesting.... After I obtained my Siglent Spectrum Analyser I decided it was surplus to requirements and was recycled... I cannot remember the varicap diode types, but this may change if other ranges are required, I just noticed the V input to the voltage regulators is marked +24V.. obviously this should be higher and is in fact +30V
