[Milsurplus] Northern Master Oscillator

[Rob Flory]

Hi, Zorro!

I used to have the master oscillator without the frequency shift
converter.  I used it as a VFO and even barefoot on 10m as a QRP
transmitter.  I think the MO made about 1 watt.  I wrapped a fine wire
around one of the tube pins to add grid-block keying.
