Re: Identifying some microwave parts

The MCSL part is an X band free running swept source,  varactor tuned. It comprises a grounded collector 2N3866 power oscillator driving a step recovery diode (SRD),  followed by a waveguide filter.   The frequency range is maybe 8 -10Ghz with a few mW out.
 
Not a lot of use for the amateur  as its stands unless you rescue the SRD for your own multiplier or use the unit as an LO for a crude Spectrum Analyser???   Supply is -24v from memory but not sure what the varactor tuning input needed.
