Barry, it sounds like you need to install the K3VFOFILTERKIT, see here: http://www.elecraft.com/order_form_parts.htm#K3 Parts
I had a lot of tuning noise on several bands. All my screws are nice and snug and my TMP cables run as per Elecraft's recommendations. Post-modification, I still get some tuning noise but on most bands (except 6m and the CW end of 10m) it's below the band's noise level. Take a look at the instructions, dig out two 470 ohm resistors and two diodes and save yourself $10. It's an easy mod to apply, but don't forget the firmware change, quote: 1. Download and install firmware revision 3.24 or later. Refer to the K3 software page for instructions. 2. IMPORTANT: Locate the CONFIG:VCO MD menu entry, and tap the 1 keypad switch until you see SPI 2; this selects the new bus clock rate. (The default setting is SPI 1.) I'm still waiting for Elecraft's suggestions to improve the hash level, but must admit, I haven't checked 12m YET because of antenna restrictions. 73 DaveL G3TJP ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
