[Elecraft] [ELECRAFT] K3: Help! No output on 80m CW

[Oliver Dröse]

Hi Tom,

sounds like a problem with either your antenna (or coax or connectors) 
or maybe RF in the shack? A friend of mine had a similar problem (only 
on 160 m) and it turned out the KAT500 picked up RF through one of the 
cables connected that drove the KAT500 internal frequency counter nuts. 
A few ferrits solved the problem.

>> Ok more detail. If I set Tune power to 30w and then press Tune, then with the KAT500 in manual it will tune down to 1.2:1. HOWEVER, if I leave it there with the tune power on,the KAT 500 starts showing 1.2, three seconds later, an bunch of relays click, the power SWR scale lights up, the fault line comes on. Then all of a sudden, it is steady again. Shows 1.2:1.. Three seconds later it all repeats. Now if I do it with CW, same thing is happening although it's more difficult to see what's going on due to the intermittent signal.. So it's something with the KAT500 and the antenna. But, voice is perfectly fine!
