[ICOM] 7546 Pro II

[John Fleming]

No one is really answering the question though.  I doubt there's a heat 
sensor, or if so, it's set very high.  I've done a lot of RTTY contesting 
with full power with the 756PRO line (mostly II) and the 706MKIIG.  The rigs 
get VERY hot, but just keep on ticking - for years now.  Not 10 minutes 
straight key down, but probably at least 5 or more with some weekly rag 
chews I do on RTTY at full power.  (The PW-1 can take the "abuse" too - Go 
Icom!)
