in rec.radio.scanner: I am just curious as to whether or not it is fucntioning well and how I can test it to see if it does have a problem. A common problem with portable scanners is that the antenna jack connection to the scanner breaks. Take the antenna off and see if the reception dies completely. If not, that could be your problem. (It just has to be resoldered.) If not, the front end could have a problem - damage from a strong signal, detuning, etc. Or the antenna could be damaged. The scanner should pick up signals from the same place the users of the system can pick up signals without too much static and no breakup. |

Thanks for the reply Al.
I wouldn't have expected the signal to die completely when the antenna is disconnected, I would have expected to still be able to hear something. However, I tested my scanner by tuning and holding a weather station, and then disconnecting the antenna. The signal went dead completely, turning the Squelch down caused static, but I expected that. So based on that, the antenna connector seems to not be the problem. I'm going to play around with it somemore and see if I can deduce the problem anymore. Thanks again. |

Maybe some ham in your area could check it for you. |
