Graham, LF,
In an attempt to reduce the signal further I have connected to my Sandpiper
HF vertical.
Now receiving with 50db attenuation & the signals are barely audible through
the speaker & barely visible on the Fldigi waterfall.
There is no copy from the MFSK4 signal with just a little from ThrobX2 &
PSK31.
I am receiving more complete words from ThrobX2 than PSK31 making ThrobX2
the marginal winner of the test, at least in my case.
A very interesting & useful test.
