[Elecraft] Re: RS232 polling noise with MicroHAM CW Keyer

[Alan Ibbetson]

Thanks everyone for all the replies about my RS232 polling noise. It 
turned out to be cable routing. I rerouted the ribbon, the speaker, and 
the RF interconnect between the KPA100 and the K2 boards. By moving 
these cables away from the IF area and the DB9 rear panel socket I have 
completely removed all the PC polling noise.

Regards,

Alan
