Set up ros / mfsk , could see the ros was decoding , but did any of
the mfsk-4 signal's decode with you ?
There was 1 ros mf-2 rx showing on my pc but no text decode
at -33 dB . .
Propagation seems to be 'odd' as I can see the beacons round 505 ,
but when Gary was decoding your mfsk
signal nothing was showing at my qth .. it was only close to
midnight , your wspr signal started to show and
decode ... but with 300 mW to the Ae last week , mf-2 was decoding
with you , so I assume the Ae is 'working' ..note other stations in
the
same boat to day ?

Ok John..
That set up may be a problem for dual watch with only 1 rx
If you set the TX to 500K usb and the MFSK4 to say 2KHz ,
that will fit inside the USB filter
Graham, LF,
My antenna is pretty narrow, and currently tuned at the WSPR section of
the band, so it precludes TX below 502kHz.
I've moved the ROS RX up to 502.0 dial - so the RF is centered on 503.5
The MFSK is on 502.4 dial / 503.4 RF (1kHz AF)
Hope this makes sense? Now I should be able to TX & RX in MFSK as well
as RX in ROS, all within 100Hz of each other.
Let's see what transpires - if someone wants to set up a ROS beacon...
