Mal, tks for the QSO.
I have a massive carrier here spot on 501 which is
making any reception on adjacent freqs v difficult.
Rx is a Redifon R408 with good MF sensitivity
and excellent vbl bandwith filters but even then it was difficult to separate
your sigs out.
The QSO was a bit tricky because I had to swap the
Ae over between Tx & Rx.
Also, I had no sidetone just the clunk of the key
and subsequent relays.
RST was nearer 229.
Source is a Marconi Marine Oceanspan 7
Tx.
The Tx is xtal controlled but has a LC osc as reserve in case the 500kHz
Xtal goes down.
I have tweaked it up to 501.
Unfortunately the HT supply to the osc is not
sufficiently stabilised so I am surprised you gave me T=9 despite the distinct
birdie tone!.
The Tx has 3 x 807s in the finals running
800V at 80mA into an impressive variometer.
I am putting out abt 2 amps of RF into a LW
Ae.
More work will be required to get a good stable signal out
on 472 when we get it.

Are you about for a quick try on 501kHz right
now? I will be quite chirpy! GW4XXF

Anyone about for a CW qso on 472/500 Khz
Daylight suitable for me, no need to work in the
dark
