Re: [amsat-bb] Icom 910H CAT problem

["Jeff Griffin" <kb2m@xxxxxxxxxxx>]

 I found my problem. It was my DB-9 shelled CV-17 clone cable. I make my 
CV-17 clone cables using the 2 transistor method. I can then get the whole 
circuit inside  a DB-9 shell. What happened is over time, the circuit 
developed  a bad solder joint. All is now well in KB2M/910land. It's funny 
how an intermittent problem can steer you wrong. Some useful info from this 
is Reinhard sent me a URL for a neat little program. It was very useful in 
diagnosing the problem...
