[ARC5] On Hacking

[J. Forster]

I was waiting for that cannard.

The TVI rep was fror two reasons:

1. Ham gear manufacturers condemned the ARC-5 and similar sets to sell
their hardware.

and

2. The ARC-5, and many other similar vehicular transmitters, had
electrically short antennas and these were resonated by the output
(variable) inductors in the sets. This was a high-Q circuit, so would kill
harmonics well.

Any time I see an ARC-5 with a SO-239, I know it belonged to a ham with
little to no understanding of its proper operation.
