[ICOM] QST - 7600

Fri Oct 9 17:50:11 EDT 2009

It's too bad that Icom couldn't set up the 7600 to do the dual watch within the 9khz or 6khz roofing filter. That would work fine for split frequency pileups on CW as the split is generally less than that, and even for many SSB pileups.  You would get the tight front end and still get the advantage of listening to both frequencies during a split frequency pileup-the best of both worlds.
