[ARC5] Power supply for chirp-free op. ?

[J Forster]

Can't help on the relay, but to run the set into a 50 ohm load, you will need a
small capacitor (50 pF range) in between the Antenna terminal and the hot side
of the load. This is to create a series resonant circuit with the roll-a-ductor
in the set. I've used a smallish air variable. It emulates a typical
electrically short antenna and the 50 ohm load is the radiation resistance.
Remember, both ends of the cap will be at high RF voltages.

Best,
