Re: [Elecraft] P3 or K3 oddity
Try moving IF connector, P3 and K3 side, disconnect and connect and check presence of spurious signal. I did same problem and fixed changing IF cable with high quality cable and connectors.

Re: [Elecraft] P3 or K3 oddity
Try moving IF connector, P3 and K3 side, disconnect and connect and check presence of spurious signal. I did same problem and fixed changing IF cable with high quality cable and connectors. In my experience, the I.F. cable between the K3 and P3 is quite finicky when it comes to the quality of cable and connectors. I have just replaced my two P3 cables with these: https://www.cablewholesale.com/specs/10x1-01103.php These cables have a copper braid and aluminum foil shield, the molded transition from connector to cable looks beefy and solid, and the connectors fit well. Prices and shipping are very reasonable. Thanks to Hank, W6SX, for pointing out cablewholesale.com as a good supplier.

Re: [Elecraft] P3 or K3 oddity
Thanks for the heads up on the BNC cables. I am not sure where I got the one I am using. I will swap out the cable and see if the issue is still there.

Re: [Elecraft] P3 or K3 oddity
Mike and Johnny, In CW mode, set the P3 for the narrowest Span (2 kHz), then use the cursor to find the difference in frequency between the VFO and the spurious signal. That will be the clue as to its source. 73, Jim K9YC On 6m I notice a noise source just above or to the right of my vfo frequency. __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to arch...@mail-archive.com
