My scanner is picking up scratchy channels?
I have a handheld Police scanner and I recently purchased an outdoor antenna so that the range of the scanner can extend further. The antenna seems to be working ok because I am hearing frequencies like before however there are several frequencies that come through as if someone is talking but all I hear is a buzzing noise, some beeps and the frequency is scratchy. This did not happen before. Also is there any way to test and see if the antenna is working up to its ability besides just listening to the scanner?? Anyone with an idea please help me…. thanks
Best answer:
Many areas have gone to a digital mode that replaces the normal analog voice you normally have heard.
This requires a digital scanner to listen if it is:
1) APCO Project 25 or P25
2) Unencrypted
Any other form of digital is not supported by scanners at this time.
Compare what your hearing to the samples here:
kb9ukd.com/digital/
This will help you to identify the source.
Also when putting up an outside antenna can also cause from problems with interference from signals you couldn’t receive or were not as strong before. This is caused by the way the scanners work and is called intermod.
dra73.org/intermod101.html
en.wikipedia.org/wiki/Intermodulation
Signals in the 929-931MHz area are commonly paging channels, also may hear this in the 152MHz, 157-158, 462, & 467 Mhz areas too for older paging systems.
The best way to know if your antenna and cable system is up to par is to monitor the local Weather broadcasts. With a good antenna and cable you should be able to pick up stations 50-60 miles away. Compare that to the stations you get with the standard stock antenna.
Look at the cable connected to your antenna does it have markings along:
Comscope/Times Mirror LMR400
Belden 9913
RG6, if run is less than 50-60 ft.
RG11, if run is less tan 70-80 ft.
Then you have good quality cable.
If you see:
RG58
RG59
RG8
RG8x
RG59
RG174
RG213
Then you have bad cable and it will need to be replaced with one of the ones listed previously.

What kind of handheld scanner do I need to listen to the police, fire and ambulance channels in Nashville, TN?
Thanks.
Best answer:
go to a radio specialty store, and first go thru their guide on publicly used frequencies. Then, armed with this information, look for a scanner that has that frequency range that you are requiring.
Hope this helps. Best of luck in your search.

how do i unlock all channels on handheld scanner?
somehow, i’ve managed to lock out all the channels on my handheld PRO-95 dual trunk-tracking handheld scanner from radioshack. the screen has 0123456789 on the top line, ++++++++++ on the second line and “all channels locked out!” on the third and fourth lines. the owner’s manual is complete gibberish to me. i need to get it back to scanning the police/fire channels asap. help?
Best answer:
most scanners have one button that says scan, and another that says manual. if it’s saying all channels locked out you most likely need to manually go one at a time and press a button that says l/o or maybe a pic of a lock, then the display should deactivate the locked out message. you will need to check all programmed channels to unlock all of them.
