[CQ-Contest] Querks with IC-756proX radios ?

[David Burger]

Just adding to the observations of George K5KG..  I also have a couple of 
these radios, and have noticed a very similar effect.  While George's 
radio died every few minutes in the heated battle of an IARU event, the 
problem I had - which was never resolved was similar... 

--> the radio all worked fine but with no TX or RX audio of any 
description (the display and all controls still seemed to work OK).... I 
powered it on and off, and it also  re-set itself into deaf/dumb mode in 
ever quickening cycles from 10 minutes down to about 10 seconds....  This 
was in the tropical heat in VK8 with 30 C and 99% humidity in the middle 
of a CQWW SSB event..    The radio still works fine even now, so while i 
don't have an answer on that.. it is definitely heat related..

This ties in closely with Georges' operation in similarly hot and humid 
environmental conditions..  It does seem like heat / humidity is a common 
element.

To put this into perspective - it has only happened to me just ONCE in 
about 4 years of abusing these neat radios in the tropics & Outback 
Australia, and turning the radio off with a big fan on it seemed to get it 
working again.  Would I ever change from using these radios - NO.
