I have a question, what about all the boat anchor people running Collins
gear that is splattering all over the band?
I learned my lesson about a year ago with a note from an OO saying that I
was taking up almost 20 KC with the Collins S line and 30L1 amp.
Just listen to one of the Collins nets now and see how wide the signals
are. Opps, I forgot, the Collins people tell me that my 756 PRO II's are
junk. Shame on me....

It's about time that those characters are told to smarten up and go by the
same rules as the rest of us. Meanwhile, you all have a nice Easter from
