[Elecraft] K3: PTT In - quit working

[Don Wilhelm]

Dick,

Eliminate the foot switches from suspicion with a simple test that you 
can do with your DMM.
Set the DMM to ohms and check the resistance between the tip and shell 
of the RCA plug.  When you depress the foot switch, the resistance 
should be quite close to zero.

Yes, it is not probable, but entirely possible that you could have 2 
faulty footswitches.  The simple test mentioned above should resolve 
that question.  If the footswitches prove good, an email to 
support at elecraft.com is in order to do further troubleshooting.  It 
could be just a matter of a faulty jack on the K3.

There is no menu entry that will change the behavior of the PTT input.  
Until this is resolved, you can use the XMIT button on the K3 to 
transmit or set the K3 to use VOX.

73,
