Thanks for that Gary,
That sort of confirms last night ,I had not thought to use the throb
mode, except I was looking for a sub 100 Hz mode
other than psk31
I will leave the system running till round 2300 gmt / 2400 bst

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.

Final set up , power ~ 30 watts per stream
same text , 60 sec repeat ..
PSK31 Cent audio 2200 Hz = 503.20k cent rf
MFSK4 Cent Audio 2000 Hz = 503,00k cent rf
ThrobX2 Cent Audio 1700 Hz = 502.70 k cent rf
Thanks for reports via email, throb, is showing well as it has 'no'
lock
