Mal, tks for the QSO.

The QSO was a bit tricky because I = had to swap=20 the Ae over between Tx & Rx.
Also, I had no sidetone just the = clunk of the key=20 and subsequent relays.
RST was nearer 229.
Source is a Marconi Marine Oceanspan = 7=20 Tx.
The Tx is xtal controlled but has a LC osc as reserve in case the = 500kHz=20 Xtal goes down.
I have tweaked it up to 501.

The Tx has 3 x 807s in the = finals running=20 800V at 80mA into an impressive variometer.
