Question about Galaxy Radios DX- 88HL Base CB Radio

1 Answer

Radio stuck in transmit meter needle is slammed all the way to the right as soon as you turn unit on

The meter is is showing full transmit as soon as you turn it on if this was an older radio i would be looking for a stuck relay or key up contacts but this radio doesn't have this type of key circuit can you help?

    I have disconnected the key circuit from the main board and it still shows that it is stuck in transmit this radio is a CB conversion with echo is there somwhere else something can be shorted to cause this problem

Have you recently changed mics ? if so it is wired wrong, if not I would check for a shorted wire in the mic connector or the mic itself.

    You've got me on this one, never heard of a Galaxy doing what you are describing, no relays to stick & mic wired correctly, my only other advise is to get your plastic or wooden screw driver & start pressing around on stuff inside, maybe you will luck into it & get it to release & then you'll know what to replace.

    In the old days I used to see this happen occasionally when high standing wave was present, but not in modern equipment. Whatever you do don't leave it keyed up too long or you'll roast the finals !

    Sorry

  • Mojorisin65 May 26, 2009

    I'll do some research & see what I can come up with, by the way if you've been in the game long I used to talk skip as unit 563, Mr. Mojorisin, but I don't even have an antenna up any more, we used to stay below channel 1 at 26.785 Mhz.anyway, Good luck !

Receives fine, needle does not move on transmit, transmit light lights


Needle on the meter might have went out . Is it stuck in one spot? If it moves during receive and goes to zero when keyed it most likely the final.

The calibrate needle wont move to the right to set whe trying to calibrate on cobra 29 ltd classic new radio


You have to press the transmit button to get the radio to send a signal that you can calibrate the SWR meter to. If you are pressing the transmit button and nothing is happening then it could be a blown final transistor, a bad switch, bad microphone connection etc.

Handheld Radio Shack CB radio TRC-230 I can hear people but no one can hear me


First, lets make sure that the unit does transmit. Get a power meter and see how much power it transmits. If no power is being radiated, you need to have a technician check out the unit.
If you have power then pick a less crowded time to test out if anyone can hear you. Other people with more powerful equipments can only be a problem when you are transmitting on the same channel and both of you happen to transmit at the same time all the time. Chances are remote that this is your problem. Good luck. es

I have a cobra29 LTD Classic and the ant warning led lights each time I key the mike. I have the radio mounted in an overhead dash, the radio is grounded to the truck via the power plug. That ground goes...


A VSWR meter is your best bet. They are cheap for cb's . If the antenna is badly mismatched you will get an antenna warning lamp on. If the antenna has a tuning coil you will see usually continuity to ground from the whip. Use the vswr meter on the radio. Set to calibrate first, transmit on channel twenty while rotating the swr cal knob. set needle on orange triangle at top right of scale. Select VSWR mode and transmit. needle should move up slightly if antenna is tuned correctly. Try chaneel 1 and 40 with same procedure. You can tell if antenna is tuned more toward the high or low frequency by how high the needle is on the scale. The higher the reading the worse the match is. If there is always a high scale reading then try another antenna that you know works.Watch for flattened/damaged/water in between braid and jacket or corrosion on coax as this will change the coax impedance drastically

With my rf gain all the way up i dont get needle movement and when i transmit the needle only move to about 2. not sure what is wrong


It could be a bad meter in the radio. there is know way to know without hooking the radio to a watt meter to see what it's really doing.

If its just the meter, its not a real problem. Some time dirt gets into the workings of the meter, and especially if it is a metallic debris, it will gum it up because there are magnets in the meter, and metallic debris sticks to it locking it up. Some times lightly taping the radio above the meter while modulating will loosen it up, but that would be a temp fix. The meter would have to be replaced. Careful when taping the radio, you don't want to cause more damage.

If the meter is just gummed up, the meter is not integral, and if it doesn't mater to you if the meter works right as long as the radio works, then you can leave it.

I can only hear the others. When I talk they can't hear and my red anntenna keeps coming on when I push button to talk.


Assuming the antenna is mounted and grounded correctly,when you try to transmit/talk does your meter needle move to the right with your voice,if it doesn't make sure meter knob is set to receive/transmit or mod[modulate] does it move to right now,if not make sure the mic gain knob is turned up or if it is a power mic,is it turned up&have a fresh battery.The antenna light could mean high swr readings which you will have to adjust by tuning the antenna with the radio meter or external meter,you can search swr adjustment on your computer if unfamiliar..some antenna warning lights are factory set too sensitive but most times are telling you there is a problem.If all is set&tuned properly and you still can't get a local signal to respond, your radios transmit finals could be blown,which you'll need a qualified radio tech to determine..Good luck& 73's

I have a cobra 25 ltd and when i key the mic the gauge of the db barley goes up. is something wrong ? also the gauge says its measuring tx power what does that actually mean/ do


TX means transmit. There are 3 settings for the meter. The top one is to measure your TX/RX that's transmit and receive. CAL is to calibrate the meter to check your SWR.

Reasons your needle may not be moving much when you key while on TX/RX. The dynamic is probably all the way down. That is your mic gain. If you turn that up when you talk the needle will swing more. If the radio is stock and not modded, you can turn this all the way up and leave it.

Also there could be something wrong with the mic. If people can hear you then its not the mic.

If people can hear you fine when you transmit, it may just be a bad meter. Not a big problem, you will just need an external meter to make sure you swr is not high.this is important because if it is over 1.5 you run the risk of blowing the final transistor.

Matching c b antenna with c b radio


here is some information that will help you test SWR with an inline watt meter. To get proper results you need to use an inline watt meter. Here is a really good site you can go to for help www.cbradiotalk.com

Equipment needed: SWR meter, short jumper coax 3 foot.
midland.jpgProcedure: The SWR meter needs to be placed in line between the antenna and the CB. Connect the antenna (normally connected to the back of the CB ) to the connector marked "Antenna" or "Ant" on your SWR Meter. Connect one end of the short jumper coax to the "transmit" or "Xmit" on the SWR meter. Connect the other end of your jumper coax to the CB.
Assuming you have a standard SWR meter the switches should read as follows: REF or SWR, FWD, and there should be a slide switch marked "set" or "Adjust". If different consult your meter's owners manual.
With the radio on the lowest channel (1 on CB) and the SWR meters switch in the Forward (FWD) position, depress the transmit switch (key up) located on the microphone. While holding the unit in this transmit mode, adjust the meter needle to the set position using the Set or Adjust knob on the meter. As soon as the needle is in alignment with the corresponding mark on the meter face, flip the switch to the Reference (REF) position. The meter is now showing your SWR on channel one. Note the value and quickly release the microphone switch. Record this reading.
Repeat the previous step on channels 19 and 40.
How to read your results: If SWR on channels 1, 19 & 40 is below 2.0, your radio can be operated safely.
If SWR on all channels is above 2.0 but not in the "red zone" (normally over 3.0), you may be experiencing coaxial cable reaction (bad quality, wrong length, etc.), insufficient ground plane, or have an ungrounded antenna mount.
If SWR is in the "red zone" on all channels, you probably have an electrical short in your coax connectors, or your mounting stud was installed incorrectly and is shorted. Do not operate your radio until the problem is found, serious damage can occur to your radio.
If SWR on the lowest channel is higher than it is on the highest channel, your antenna system appears to be electrically short. Your antenna length may need to be increased.
If the SWR on channel 40 is greater than that on channel 1, your antenna is considered to be "LONG" and reduction of physical height and/or conductor length will correct this situation.
