10k switch
The on/off control is has a 10K vol control? Switch and control can be tested with a ohm meter---switch will read open until switched to on (no power connected to unit) and control that is 10 K will read that from outer lugs on the control.
Will a diesel 360-3 mic ork on a galaxy dx99v
- The Diesel Electronics CB will work but you have to wire it as stated below.
- #1 Shield and Black - Ground
- #2 Yellow - Audio
- #3 White - Transmit
- #4 Red - Receive
- I don't know if anyone before you has re-pined that mic or not so if you just remove that little Philips screw at the mic connector and then give it a quarter turn you can slide the connector out and take a look and compare the wiring. The actual numbering for the pins on the Galaxy 4 pin mic connector is as indicated below in the diagram. As you look at the mic tip make sure the indent on the mic is as it is the diagram.
- If you have any comments please feel free to leave them here.
- Hope this helps and thank you for using FixYa.

Frequency starts to drop and
Possible causes
- Solder joints of course even the shiny ones that look good. This would be most likely dirt and corrosion just add electrical flow you get resistance then it restricts or insulates. A plastic probe used to press down on an area you suspect with power on can be very enlightening.
- Crystal or capacitor failing.
- Pll chip............ low voltage to this component
This being an older radio that has probably went for long periods without use it would not hurt to go thru this radio changing the electrolytic capacitors they dry and leak. I suggest a full alignment done on this Jewel afterward.
Good luck hope this was of some help.
I have a galaxy 99v when i key the mike the
sounds like either a bad.mixer crystal or the vco is out.of wacky. if it is the crystal then you can try reseting it. it is a 10.240 crystal. heat the crystal wig a soldering iron for white 8 to 10 seconds. if that doesMr work replace it.
Have a 99v was talking
Check the mic gain.
Make sure it is not in PA mode.
Make sure the mic jack in the radio doesn't have a broke or loose wire.
Those are a few things I can think of based on the information given. More information is needed if these will no solve the problem.
Does it turn on?
Does it key up?
If it keys up is there carrier?
How many watts is the carrier?
Are there any mods done to the radio?
Does it have a roger beep installed? What kind?
Does it have an echo board install? What kind?
Did you do the mod or some one else?
What is your SWR?
Is the display flashing when you key it?
Are the displays lit at all?
Did you disconnect the power cord after you turned it off, and reconnect it?
What channel are you keying up on.
Was/is the case off the radio when you tried it or were you working on it at the time of the failure?
What mics have you tried.
are you using talk back?
did you some one on another radio tell you they do not hear you, or are you going by no swing on the meter in the radio?
Could the meter be bad?
Modulation fades in and out
Would like to help just no enough info. transmit or reception?
POSSIBLE
Power cord/connection.
Base i would assume not to be moble your power supply weak.
Radio capacitor bad on pcboard of radio.
Failing element in mic.
Short in mic cord ...intermittent
AGC circuit of radio which equalizes volume
Frequency counter is running on
You are obviously off frequency. Two things. One does it just cycle 2, 3, or 4 frequencies and then continue to recycle those same frequencies despite going up or down in channels? If this is the case there is a board in the CB called a PCB board. If you open your radio it is a little circuit board. Held onto the side of the radio by a screw and has two or three connectors leading to the board. Replace that little board and your radio will be good as new. I have seen radios come in my shop many times and this is the fix. What that board does is send a signal to the crystals to start mixing a frequency. When it goes out it just sticks where it is at or only mixes a small few frequencies. Here is a link to a place that can take care of you. http://maycomcomm.com/ I trust Maycom with all my new Galaxy parts. Now for the other option. Is it just randomly switching frequencies no matter the channel? We call this oscillating. If this is the case it could be a bad crystal. Could also be a bad PLL. If the CB is Oscillating I recommend you take it to a tech with an oscilloscope to have it repaired. You have to be able to set the mixers and an oscilloscope is the only way. This is the most technical part of the CB (front end)
Frequency counter displays two digets
Turn that fine clarifier a 1/4 turn or so to the right. I own a Galaxy DX99V and sometimes if that clarifier is just right it will drop down a hundredth of a MHz just like that when the mic is keyed. Your radio is just fine. Just adjust that clarifier a tad. The Galaxy DX99V is one of the best radios out there. I love them. -73-
Cant get my 99v to
Please be more specific. It could be the channel selector to the channel board in your radio, to a slew of different things.
Galaxy 99 has same frequency 27.185 on am also on
The frequency doesn't change when you change to USB or LSB. Basically the AM frequency takes up a certain amount of space, known as bandwidth, so it could fill in for example use 50 hertz above and below 27.185 giving 100 hertz bandwidth. When you use sidebands the am bandwidth is split in two so the upper side band would use the 50 hertz above 27.185 and the lower side band would use the 50 hertz below. The idea is that twice as many operators can operate without interference.
My cb won't pick up unless the person talking to
Check your SWR's, if they are good have the radio checked out.. ITS FREE at any GOOD CB SHOP. IF they charge to look/bench test. be Leary of them. we have several here on I-35 in temple/Waco area that charge a bench fee.. and thats **** for the consumer.. We DO NOT charge for that, or check the swr's.. only if parts are needed.
