Receivers grounding out
I have an R-2000 and 830S by Kenwood.
Both radios do not receive when plugging in coax connectors into the S0-239 receptacles. I've eliminated the cables as the problem. I believe it is possible salt air corrosion internally in both radios. The signals and noise drop out completely when screwing in the PL-259 connectors all the way in and tightening them down. When they are only half way plugged in I get normal reception when wiggling the cable but they are not screwed in completely and not making a good electrical connection. I lived on the beach and sometimes would open the windows for ocean breezes. The 830S was right next to the open window and the R-2000 was sitting on a night table a few feet away from the open windows. I've eliminated the cables themselves and suspect salt air corrosion internally in both radios. Is there a spray contact/solder connection cleaner available on the market that might help solve this problem? Recently I had the S0-239 replaced onthe 830S and still have the same reception problem. The noise and signals drop out completely in both radios when screwing in the coax connectors (PL-259) completely. Thanks for the help! 73's K4JDP-John |
I know that you have checked out the cables, but it does sound like it could
be a problem at the antenna end if it is not the the cables themselves. The fact that you can receive signals when the plug end is only halfway in illustrates the fact that the receivers are probably working properly. Could be a short to ground at the entenna end. I am assuming that when you checked the cables you did do an end to end check with an Ohmmeter, both for continuity and for center conductor to the ground shell for a short circuit.

This a classic case of a shorted connector/cable/antenna. W4OP |

This a classic case of a shorted connector/cable/antenna. W4OP Could be the connector in the radio itself, the center pin connection could have been enlarged by a poorly soldered PL259, thus expanding the fingers in the connector. Had this problem on a Yaesu 757GX, squeezed the fingers in via a knife blade, no further problems. Always check the center conductor for solder on the outside of the plug, it changes the diameter and can mess it up for future cables that are correctly assembled. YMMV Use the usual techniques to reply via email. Molon Labe! |
