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...
