[ICOM] 756 PRO Question

[David S. McCallum]

Hope this goes through OK. I had my SB200 connected to my PRO and it
worked great on 10,15, and 20m BUT, when tried I 40m it wouldn't work.
Checked everything I could think of and even changed the antenna switch
settings from auto to manual to off and it still wouldn't tune up. I
don't have a 75m antenna that I could hock up and check that band. A
friend brought over his solid state amp and it wouldn't key up either.
I'm using the W3ENY amp keyer cable interface. ANY IDEAS GANG, Mac
