I have converted my old BC-221 Frequency Meter into a Ruggedized QRP transceiver.

The BC-221 was the primary frequency standard in WW2 for all communications. They were on aircraft and on the ground'

This is a 'One of a Kind' radio. See “QRP Radio Disguised as a BC-221”, CQ Magazine, Feb. 2018, p. 16-17, for the entire story.

It looks like a real BC-221 but It has a W8DIZ '1 Watter' inside.

The '1 Watter' is driving a Pacific Antenna, 10 Watt amplifier.

It is has a Low power (1W) / High power (10W) switch. It is operating Class C. All solid state, no tubes.
