My K3 is serial #5102 purchased in January 2011. My VFO B knob has just cracked: it's spontaneously developed ugly linear fissures across the face of the knob. The cracks begin nowhere near the screw hole. There are two cracks. The rig has spent its life in an internal room with no UV exposure

Hi Phil, It does take several seconds for the K3 to initialize the P3 at power up but if some parameters are not getting initialized it must be a hardware problem with the serial interface. It sounds like you have already confirmed that the locking screws on both ends of the serial cable are tigh

Software doesn't age over time. It could be a problem with pin contact resistance. You can clean the connector pins off and see if this helps. 73, matt W6NIA On Fri, 23 Dec 2011 17:40:35 -0800 (PST), you wrote: >I've got a P3 connected to my K3 with all the proper connections. > >K3 info: >s

The P3 is usable without the mod but it increases the sensitivity of the P3 display. On the low bands you probably won't notice any difference but if you do much 10 or 6 meter operating you probably want to make sure the modification has been done. I'm not sure of the serial number of the changeo
