[ARC5] ARC-5 as VFO

[mstangelo at comcast.net]

In the 1970's I got some KVG 9 Mhz crystal filters in a trade and decided to build a Sideband/CW rig for 80 and 20 meters.

I wanted a stable 5 Mhz VFO and looked for a suitable capacitor. I settled on a capacitor from a command transmitter because the 100:1 gear ratio was ideal of my application. It turned out to have very low drift and the tuning was smooth a silk. I even found a nice knob which fitted the shaft(which I believe is 3/16 inch).

I probably still have that VFO. I'll have to dig it out this winter.

Many years ago, I used a BC-459 as a VFO for 6-meters.  That VFO was considerably more stable than the VFOs being marketed by Gonset, National, etc. Glen, K9STH

  I am always amazed about the stability of the ARC-5 TX when used as VFO with reduced plate voltage.
I picked one up, greatly modified with VR tube etc. But plugged in the power cord and it was remarkably stable, especially after
a few minutes of warm up.
  I used them for VFO's for my 10A and 20A years ago. But still amazed.
