[Elecraft] K2

[jerry]

All,

    My new K2/100 has a scratchy volume control knob.  Also, it still 
makes noise
at full CCW.  I suspect that the volume control mod was not done.  I'll 
be taking it
apart to take a look.

    If none of the mods were done, it might make sense to just transfer 
the KPA100
& KAF2 to my QRP K2, which does have the mods.  I already looked, and 
the QRP_K2 DOES have
the mods for installing the QRO module.

   Also, the headphone jack feels a little looser on the new K2.  Still 
works fine, just
a teensy bit looser.

   The finger detent thing on the front of the tuning knob had come loose 
- I'm guessing things out hot out there in shipping.  I stuck it back 
on, it's not going anywhere.  But that gave me a thought - is there a 
finger detent with a bearing out there?
