| Post subject: | BC796D Problem |
I have a puzzling anomaly going on with the 796D in my car. In bank 1, I have local law enforcement, fire, etc., and in bank 2 I have WSP stuff. No priorities are turned on, and in fact I changed some of the unprogrammed, locked out channels to be the priority channel after this problem showed up. The delay setting is at 2 seconds. When the scanner stops on a channel with activity in bank 1, it will stay there for a second or two then continue scanning even though there is a carrier and voice still present on the channel it had stopped on. It will stop again the next time around, but then does the same thing. The lcd meter shows a strong signal, so it doesn't make sense why it acts like the carrier had dropped out. The mode had been set for NFM, but I changed it to FM just in case that had something to do with it. I can be driving through the middle of town for the police dept. it stopped on, but for some reason it won't stay on that channel like it's suppose to and wait until the 2 second period is over. This does not happen with bank 2, where the WSP freqs are programmed. Any ideas? Bob, KB7ADO |

Is the first bank trunked or conventional ? Delay is set separately for each. Sounds like the delay is set at "-2" instead of "2". |

I have verified that all the channel delays are set for 2, not -2. The frequencies are all VHF and are set for conventional. |

There is a 'data skip' function that might be at work. I haven't played with it much, but it's supposed to detect non-voice signals and ignore them. Otherwise I'd go with Rich and the delay settings. Does it sound normal (no spikes or dropouts) if you hold on the channel? |

I have a 796 and every once in a great while it goes bi-polar on me and starts doing something that it shouldn't be doing. The usual 3-button mamba dance to reset the scanner usually puts it back into the proper state of mind. Hopefully you have software to read the current channel configurations so that you can save and reload after the reset. |

If I choose one of those channels manually, the transmission sounds normal without any dropouts. The problem is also erratic in that when it is scanning, it might stay on one of those bank one channels for 2-3 seconds then suddenly resume scanning again, but the next time it might resume scanning after 1 second. I'm considering duplicating bank one's contents to see if the problem repeats itself with the same frequencies in another bank. |
