Droped channel to 17 and frequency counter don't work?

Most likely, something is programmed wrong. Brand and model would help more. If over the counter radios, the frequencies are likely the same. The "tones" which have many names are incorrect and both frequency and tone must match. One radio may be in "monitor" mode, so it will hear everything on that channel. Grab the book, slowly program each radio writing down each setting. Get the frequency and tone first. Add features later.

Alot of times its because no one is on frequency but there is a thing called a dead channel. to check this out have a friend join you on channel 40 and start talking to each other .If you can hear them its not your radio it because no one else is on . What kind of radio? If its a cheap one , like under 50 bucks , get adventurous and buy another at 75 bucks. What I mean is you get what you paid for. Now if you can't hear your friend talk then get a meter with a frequincy counter on it and make sure you are on frequency 27.405 or channel 40 .

on the face plate is a button for the counter ,try pushing it several times to see if the dot moves. As long as the channel display is reading the correct channel you should be ok but you want to correct this problem . If you can't correct it contact Galaxy and they will have a tech talk to you.

When talking on side band, they need to tune you in on their end.

Short answer, maybe. It depends on whether you have a 14 channel or a 30 channel Talk-About. The Motorola Talk-Abouts operate on the FRS frequencies (14 channel) or FRS & GMRS frequencies (30 channel). The MU21CV does cover a few of the GMRS frequencies. (see bold numbers)

GMRS Frequencies
462.500, 462.575, 462.600, 462.625, 462.650, 462.675, 462.700, 462.725, 467.550, 467.575, 467.600, 467.625, 467.650, 467.675, 467.700 & 467.725

FRS Frequencies
462.5625, 462.5875, 462.6125, 462.6375, 462.6625, 462.6875, 462.7125, 467.5625, 467.5875, 467.6125, 467.6375, 467.6625, 467.6875, 467.7125

MU21CV Frequencies
464.500, 464.550, 467.7625, 467.8125, 467.850, 467.875, 467.900, 467.925, 462.575, 462.625, 462.675, 464.325, 464.825, 469.2625, 469.500, 469.550, 462.7625, 462.7875, 462.8125, 462.8375, 462.8625, 462.8875, 462.9125, 464.4875

I have found bad cabling and bad grounds on this and the other board in the freq counter can.

Okay.

You do set this up like a regular CB. The meters refers to how long the waves are. CB is 11 meters. So its very close. The antenna woud be tuneds slightly shorter. Use the SWR meter in the radio to calibrate just like you would a normal cb.

Now for the ABCDEF knob. each letter is 40 channels in the band. So A would be 1 - 40 channels, then B would be the next 1 - 40 channel frequencies. You use the frequency counter in the radio(providing that model has one) to tell what channel you are on.

Here is some info one the frequencies in the band.

Now for AM and FM. this is the type of modulation you are using for transmit and receive.

CB transmits on AM or SSB. Amplitude modulation or Single side band. Most CB radios only have AM. But some also have SSB. None will have FM.

FM is frequency modulation.

10 meter radios can have AM FM SSB and DSB depending on the model and options it comes with.

So your radio has 6 ranges for freqency. each is 40 or 50 channesl. Not sure what model you have. If it has 40 then you have 240 channel freqencies.

with AM and FM, you double that, because you can talk on AM or FM on all the channels. If you are on AM and some one transmits on FM unless they are really close, you will not hear them at all, but if you do with will just be garbbled noise.

Also Am and FM both work a little different with range etc.

Now, you may be able to talk on the CB channels as well. Cb starts at 26.965 MHz and ends at 27.405 MHz. The channels are all .010 MHz appart.

Hope this helps

I am guessing that you are talking about getting it to talk on the FCC Citizens band. I am not too firmiliar with connex, but this will work with any radio with expaned channels.

Usually you use a frequency counter to see what frequency you are on when you are playing with the bands.If you do not have a frequency counter you can find the CB this way.

If its in a mobile, or you are not really far from a highway where big rigs travel, you can flip to channel 19 on the channel sellector then flip through the bands checking each time to see if you are on the CB 19. When you start to hear truckers or you get a radio check from a trucker your on CB 19. You can always ask the person, "this is 19 right"?

I recomend geting a frequency counter.

With out a frequency counter to tell you what freq you are transmitting on there is another way.

Turn to channel 19. mess with the switches untill you hear truckers on the highway. then you have got it.

Otherwise pick up a frequency counter on ebay.

If you have a frequency counter, and a set of TV repair tools,( a set of special screwdrivers) You can tune the transmit on it. I would not do this unless you are skilled in such things.

The easy thing to do is take it to a cb shop. Usually you can find them at truck stops. They usually charge $30 for an alignment.

If you think you can handle it, I can try to talk you through it.
