Hi Bill, Tried your experiment, and my main VFO jumped to 5.069.029 while the sub VFO stayed at 5.999.99. This was with both receivers linked.
Trying the experiment again, this time with both VFO's unlinked as you had requested, when I tune to 5.999.999 on the main, the sub also goes to 5.999.999. However, tuning back up to 6.000.000, the sub VFO readout now jumps to 6.056.95. I could hear the relay clicking during both experiments. As for my motorboating issue, this is not something that you hear if you just let the receiver sit at 5.000.000. Instead, the noise only appears when you turn any VFO or filter knob... if you turn the VFO knob quickly enough, then it sounds like a motorboat. This happens from approximately 4.899.91 to 5.102.35 What's really weird though is that if I happen to come across a broadcast station anywhere between those frequencies, then the motorboating noise will stop until I pass the station. After that noise picks up again... it's as if the receivers don't know what to do with themselves when there's no signal received between those frequencies, and they decide to inject noise until another station pops up, or you reach the end of this particular frequency area. Now if I stop turning the VFO, then no noise... just band static. I uploaded a video that will need VLC to play back. I hope you can view it and give me your thoughts. 73, James KC2UEE -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of William Evans Sent: Sunday, February 22, 2009 7:54 PM To: William Evans Cc: Elecraft@mailman.qth.net Subject: Re: [Elecraft] Strange behavior when tuning around with SUBreceiver LINKED Looks like I may not be sticking to my explanation after all. Try this and see what you get: WITHOUT the SUB Receiver linked, tune the main receiver to 6.000.000 MHz. Be sure you can see the frequency of the Sub Receiver on VFO B area and the tuning rate is FINE. Push A>B twice to synchronize the two VFOs. Now tune the main receiver to 5.999.999 MHz. You should hear a slight click. Look at the frequency of VFO B. Mine read 5.346.50 while the main receiver still read 5.999.999 Now tune back to 6.000000 on the Main Receiver. Both VFOs on my K3 read 6.000.000 mmmmm...... something fishy here! Any explanations, anyone?
