Hi Jay, Chris, LF,
 
first option: To check sensitivity=20 and frequency lock, I like to = keep a Loran=20 line in at least one of the two display slots. In Europe,=20 the Sylt + Lessay line on 137778.37045 would be my = natural=20 choice.
 
Another option would be to simply = move=20 down to 137780.00 center. Integer Hz multiples would allow to = build a=20 relatively simple GPS-synchronized TX, based on a = sample-hold at=20 1pps. Of course this QRG could then only be used by one = station=20 at a time.
 
In case someone overseas would like to = set up=20 a narrow grabber, I'd suggest 136170.00 center for European TA = transmissions. Looking into the other direction, I guess the = prospect of=20 sub-millihertz grabbers in the Far-east or Pacific areas might stimulate = quite a=20 bit of activity.
