[ARC5] Reviving squealing "command" receivers (re-capping)

[Bob Macklin]

About the only thing I use the IB-2 for is to build precision capacitors for 
filters or select resistors where more than normal precision is required or 
the value is between standard values.

I do not use it very often.

I also have a Heathkit QM-1 Q-Meter which I do find to be a useful 
instrument for RF work.
