To expand a previous posting: I can only speak for the cable that was supplied with my own P3, but that was definitely the cause of spurious signals on the display. The signals were not strong, but they made it impossible to watch for weak openings on the 10m and 6m bands.
After cutting away the strain relief moldings at both ends of the cable, I found that the coax shield was not correctly crimped onto the plug body. This was undoubtedly the cause of the signal leakage. Continuity looked OK on the ohm-meter, but signal levels at the IF input of the P3 are extremely low so this was a case where simple DC continuity wasn't good enough. Ferrite beads at both ends of the cable did make some improvement (which was a big clue about the cause) but ferrite beads would not have been the correct way to fix the problem. The only correct way was to use a correctly assembled cable. 73 from Ian GM3SEK ______________________________________________________________ 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
