Just insert a sausage in there. A sausage is meat with skin around it.... a finger is the same thing.

Realistic pro 2021 is broken


Ummmm....the radio is at least 14 years old...ya think? They originally had a one-year warranty on them unless you purchased the 3 year warranty. In a word...no.

My scanner always stops on channels that are not doing anything.


The way this works is the radio autoscans across the bandwidth of your radio model and stops at the highest levels that break the squelch you have set. Some of the more expensive models will let you "skip" certain frequencies(channels) but none will let you add them. You can turn your squelch level up and down and this will recieve more or less frequencies within that radios range. Hope this helps.

Problems setting up Motorolla GM300


It is either a programming problem, such as the Rx is not programmed correctly OR your radio needs to be looked at by a technician to determine the issue.

I cannot get Battery Indicater Light to quit beeping


Hi,

There could be three (3) reasons why the low battery indicator is activated:
1. weak/undercharge/discharge batteries;
2. dirty/corroded/loose battery contacts/terminals; and/or
3. internal fault with the electronic sensing for battery level/state.

Corrective measures would require:
a. replace/recharge batteries. The new rechargeable batteries need at least 16 hours of charging time;
b. clean, scrape, tighten (need to bend a little more towards the battery terminals) the spring/contacts of the battery holder;
c. (on the internal fault) your best bet might be to seek the services of a professional electronic technician since this would need familiarity with electronic components, their circuitry and diagnosis, perhaps a bit of soldering and the use of a DVM.

Hope this be of help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Check the squelch on your radio thats not recieving. If there is a monitor button ( when pushed you will hear static) try pushing it.. then get someone to call you so you can check if you can hear them. On these radios you have 2 types of squelch....1 is called carrier squelch.... it basically opens when there is a strong enough signal. This lets you only hear strong signals and "squelch out" the distant ones and background static. The2nd. is "tone squelch" ... with your radio they are often called privacy tones. If you have 2 radios set with the same privacy tones you will only be able to hear each other... only radios that are transmitting with that privacy tone will be heard on your radio. Its a high frequency tone that can't be hear by the human ear that gets "embeded" with the transmitting signal. The recieving radio hears it and opens the squelch. So... if the radio thats rxing (recieving)your signal has its squelch set for just carrier squelch it will hear any signal thats strong enough to break the squech open.... basicaly any radio within a certain range. But if your radio (one with problem) has its squelch set for privacy tones you will not hear any other radios except the ones set with the same privacy tone.... the squelch will not open until it gets a tx signal with the right tone.... so if the txing (transmitting) radio is not using tone squelch but is using carrier squelch.... and the rxing radio is set for tone squelch... the rxing radio will not hear it. With tone (privacy tones/codes) squelch you need a tone to open the squelch and then the audio can be heard... with carrier squelch the squelch will open if ANY radio is within a certain range. Check the squelch setting on the problem radio... it could have a privacy tone set. Try pushing in the monitor button so you can hear static ( you want to hear everything including static) on both radios... tx on one radio at a time and listen if it can be heard on the other with the monitor button pushed. If you can't hear any audio when the broken one is transmitting then it COULD be the mic.... if you can hear both radios with the monitor button activated than the radios are txing and have tx audio and are working... if thats the case its the privacy tones that are the problem. Take care
