Hi Paul,

Will you run some EbNaut tests on LF some day?
I think you will need less power, maybe you can use the same PA with the same core and same windings.
LF has much less QSB and we could do daytime tests...

Running again, hopefully for a bit longer this time.

 Freq: 477690.00000 Hz

After a cup of tea I had a flash of inspiration.

A small change to the circuit has cured most of
my problems.   Now the transformer is barely warm
and no fan required.

Now at DC in 65V 3.22A and 140V RMS on the long wire.

With the slower symbols and extra power, should be
6dB or more up on last night.
