[Elecraft] loss of PTT on PSK

[John Wiener]

Hope this isn't too 'OT

Just suddenly lost PTT on PSK for my K2/100
I have PTT with mic but not with Signalink SL-1 and Griffin USB  
interface.

I wonder if anyone has experience with the SL1  whether they fail  
after a year or two (mine is about a year old)
maybe it's the cable from the SL1 to the mic socket but it doesn't  
seem to be intermittent.

Any ideas?
