[Boatanchors] suggested crystal frequencies?

[howard holden]

For casual operation, best to stay 3525 to 3550 and 7025 to 7050. Those 
are the busiest parts of 80 and 40 CW. If it were me I'd pick two freqs 
around XX30 to XX45. You'll find it pretty easy to make QSOs in those 
regions. Stay away from 7040 as there's digital junk on there. If you 
want slow speed CW, the slot from 7100 to 7125 has some activity.


The 90A is a good rig, nice and conservative on the 807s.
