Hi Jay, Chris, LF,
 
first option: To check sensitivity and frequency lock, I like to keep a Loran line in at least one of the two display slots. In Europe, the Sylt + Lessay line on 137778.37045 would be my natural choice.
 
Another option would be to simply move down to 137780.00 center. Integer Hz multiples would allow to build a relatively simple GPS-synchronized TX, based on a sample-hold at 1pps. Of course this QRG could then only be used by one station at a time.
 
In case someone overseas would like to set up a narrow grabber, I'd suggest 136170.00 center for European TA transmissions. Looking into the other direction, I guess the prospect of sub-millihertz grabbers in the Far-east or Pacific areas might stimulate quite a bit of activity.
 
Best 73,
Markus (DF6NM)

We previously discussed moving the uHz grabber to avoid QRM to QRSS30 beacon MP (VE3OT) on ~137780.3 - 137780.4. Do you and Chris have a new frequency in mind?
