The last known frequency (previous weekend) for Mitch was 780.5 but it does drift around a bit.

There is a small amount of 'wiggle room' on the DF6NM 'high sensitivity' grabber if you would like me to QSY. Jay W; /rsgb_lf_group-archives/html/rsgb_lf_group/2011-09/msg00260.html (16,476 bytes)

The Russian line on 775 tells me that the receiver had stayed in lock all night, so it must be real. Yes it would be good to try the same parameters again.

There's a frequency locking problem on my Bucharest LF receiver which makes it unsuitable as it is now for this kind of work.
