[Icom] 756 Pro II + 60 meters

Mon, 21 Jul 2003 19:46:31 -0400

My PROII seems to hit 40-45 watts OK up thru 5.4mhz and since 50 ERP is 
all you can use on 60meters anyway, its not a problem. Once you get 
above 5.5mhz (for MARS work) the power drops off real quick. My 
IC-706MkII and Kenwood TS-940SAT both work fine in the  5.0-6.0mhz range 
on MARS, only the IC-756PROII is not up to snuff.
