Thanks Rik
Some time ago I did the TS440 mod for removing the 20dB att, but
restored the original situation immediately.
It's useless... So much shit coming in.
Heard yr QSO this eve with Louis
What a luxery problem... Your antenna coil is producing so much heat it
melt the snow!
Anyway your sigs were vy strong here.

Jan,
I am using a Kenwood TS440 too. I find it a very good RX, both on
137kHz as 500kHz.
It has by default a 20dB attenuator activated between 500kHz and
1.6MHz. But so far I found no need to remove that, as I am using the
TX antenna (lazy-L, 11m high, 25m long) also for receiving.
For receiving DI2AN's WSPR I used the 10dB extra attenuator and then
reduced RF gain for a stable s-meter. The soundcard is connected to
the back audio out connector as, the level there is independent of the
LF gain.
