Re: pro-94 no rec
First guess is to check your antenna. Better yet, do a quick swap with someone and try their antenna. If that does not change it, then check to see if the attenuator is turned on, and take it off. Recheck your settings by the book. Hope this helps,, Mechanic

Make and model of unit ? And does it receive a programmed channel when set to it on manual mode "NO SCAN" ? If it does, program your weather channel on a unused channel in manual mode, and adjust discriminator coil for best audio sound, usually no more than a half turn either way. Discriminator coil is usually near 455 or 450 khz filter, a small square box, usually Black or Orange. Then the squelch and scan operate properly. Stopping on an active channel.
RX represents "receive" This indication will be present whenever the speaker is producing audio. The "buzz" you're talking about is probably static, and is technically audio from the speaker. To silence the "buzz" adjust the squelch just until the speaker falls silent. The RX indication should be off at this point.
It is important to note that the squelch is designed to keep the speaker silent until a signal is detected. You adjust the squelch based on the level of static at a particular time and at a particular location. The static level may change depending on those variables. If you adjust the squelch well beyond the point that the speaker is silenced, you may not be able to hear transmissions or calls to you unless the caller's transmitter is physically close to you. This is why the squelch should be adjusted only until the static is stopped and the speaker is silenced.
To verify that the scanner is working properly, program one or more of the weather frequencies(162.4, 162.425, 162.45, 162,475, 162.5, 162.525, 162.55, 161.65, 161.775, 163.275) into memory and then scan. NOTE: Not all frequencies are in use in all areas, so you may need to try several. If you receive the weather broadcasts, then you may need to adjust the squelch setting on your scanner to receive local signals. You also need to verify that the frequencies programmed into the scanner are valid, active frequencies in your area. For a comprehensive database of active frequencies in your area, and a lot of other useful scanning information, visit:
If the scanner fails to receive the weather broadcasts, you need to check the antenna connections inside the unit and/or have the scanner checked/repaired by a qualified technician.
Turn the scanner on and volume up all the way, turn the squelch until you hear static, then turn the squelch down slowly until its silent, press scan, has it ever been programed? Just a thought. hope this helps..
First you'll need a list of frequencies to program. For a comprehensive database of active frequencies in your area, visit:
Once you have your freq list, power the scanner ON,and:
1. Press PGM. Then enter the channel number (1-200) where you want to store a frequency, then press PGM again. 2. Use the keys to enter the frequency (including the decimal point) you want to store. 3. Press ENT to store the frequency into the channel. Press DELAY if you want the scanner to pause 2 seconds on this channel before it proceeds to the next channel after a transmission ends. 4. To program the next channel in sequence, press PGM and repeat Steps 2 and 3.
Operation • To listen to a weak or distant station, turn SQUELCH counterclockwise. If reception is poor, turn SQUELCH clockwise to cut out weak transmissions. • If SQUELCH is adjusted so you always hear a hissing sound, the scanner will not scan or search properly.
Need the full manual for your scanner? You can download/print it here:
Performing a RESET will not clear/erase frequencies or other data programmed into the scanner. If the RESET doesn't work though, you may need to INITIALIZE the scanner. That procedure will clear all programmed data and return the scanner to its "as new" state. Need the manual for your PRO-82? You canb download/print it here:
Just fixed my squelch problem; I don't know how it happened but Resistor 138 was burned & intermittant. It was so badly burned that I could not read the color code but it measured 880 ohms intermittantly. I replaced it with an 860 ohm carbon resistor & all seems well; time will tell. R-138 is located on the circuit board right behind the squelch potentiometer. R-139 is immediately behind the pot & R-138 is next to R-139. All I had to do is remove the 4 screws on the back of the case & the unit splits in half. I clipped the old resistor out leaving a bit of the old leads so I could solder in the new resistor without having to get to the backside of the circuit board. Scanner is working as I type this & I hope it does not burn out again. Hopefully this is the same problem in your scanner & an easy fix. Good luck.
This is just a guess but sounds like your antenna connection (inside the unit) has broken. If you use the antenna as a handle it will eventually break. Radio Shack will repair it for a flat fee of $40 (that was the price the last time I checked) plus shipping. Or if you are really good at soldering and have good eye sight, you can repair it your self. Your local radioshack should be able to send it in for repair.
I have a Radio Shack Pro 97 Scanner that I received as a present 1-1/2 years ago. It was working just fine and then suddenly there was no squelch or volume. The keys make noise when pushed, but there is no sound for the squelch or volume. The scanner scans the frequencies but does not stop and play. I went on line and found that other people were having the same problems. I went back to the store that the unit was purchased from and received no help what so ever, they said it’ s off warranty and I was out of luck, nice way to do business??. I think that something that cost as much as this should not be junk after a short period of time. I hope you can help me with this problem I do like radio shack, but I can’t afford to buy items that don’t stand up. Sincerely Greg Stevens e-mail firstname.lastname@example.org
