[ARC5] QST articles.

[Bob Macklin]

What many people do not understand is that the ARC-5 transmitters were
designed to work without a resonant antenna. The rotary inductor was
provided to make the transmitter happy with the short antenna.

If you want to connect an ARC-5 transmitter to a 50 or 75 ohm resonant
antenna you can just move rotary inductor to the minimum inductance.
