K2 new build teething problem

[Peter M0RYB]

Hi

 

I have just completed the basic build on my K2 and have had a CW qso, all
works well, apart from a noise in the headphones or on the speaker when I
let go of the keyer paddle, dits or dahs, it is all the same.  It sounds a
little like a ricochet, or perhaps a midget in there hitting a dustbin lid
after the character has been sent.  It happens on all bands.  My qso partner
did not report any key clicks.

 

Any ideas? - apart from taking the dustbin lid away from the midget, of
course.

 

Peter

Peter,

I would need more information about your K2, options and menu settings
to give a better answer, but ---

With no other explanation of how your K2 is configured, I would suggest
you try changing the 8R Hold menu parameter, and/or look at the T-R
delay menu parameter which normally would be set in the range of 4 to 8.

Don,

Thanks for the reply. My K2 is just the bare bones transceiver, with no options added and I hadnt changed any of the default options.  I did change the 8R Hold parameter to 'Hold' which I think was its original setting.  I also had some voltage checks to make following advice from Gary at Elecraft support, all of which were within limits.  In any event the problem seems to have resolved, and I would thank you for your help.  Interestingly I have not been able to recreate the fault by reversing the 8R Hold parameter.  I hope I didnt just disturb a bad solder joint enough to make it good doing the voltage checks, as that might mean it will recur at some time in the future...
