Hello Gregg, If these are indeed pulses generated by the encoders, would replacing them solve the issue, or is this a design problem?
Could this noise be masked out in firmware, or is it a hardware issue that can't be solved via software? I do recall hearing about some people having similar problems with their rigs on 6 meters. In my case, 6m is quiet with no EMI noise. What's troubling me now is that some people say this is normal, while others like the good folk over at Elecraft tech support cannot replicate this issue on their K3's. 73, James KC2UEE -----Original Message----- From: Gregg [mailto:w6...@bellsouth.net] Sent: Saturday, February 28, 2009 5:55 PM To: 'James Sarte' Subject: RE: [Elecraft] Weird EMI issue... part deux James: I suspect that what you are hearing is an artifact of the pulses generated by the tuning encoder. These pulses are audible on some K3s on 6 meters. The fact that they are not as loud with the pre-amp on is most likely due to an increase in the noise floor when the pre-amp is activated that somewhat masks the pulses.
