Question about Galaxy Radios DX-979 40-Channels Base CB Radio

1 Answer

Power meter on my dx-979 barely moves off of 0 when transmitting the swr meter also hovers around 1.0 no matter what channel...not used to seeing such low swr readings and almost nothing on the power transmission. My antenna is a fs-ii 4' deluxe tunable grounded on my truck chassis. Any thoughts?

I would check the radio with an external meter to see if it is the transmitter or the Meter in the radio. If it is the meter in the radio it could have a bad detection Diode or just oout of adjustment or even a bad calibration pot. other wise start looking to fix your transmitter like finals or other similar problem.

Power decrease in my galaxy dx979


As you go up in frequency do the SWR (VSWR) go up or down? what frequency did the antenna get tuned at ?

Galaxy DX 98VHP meter stopped moving . There is no swr reading, nothing. Even with a seperatye meter atached or a dummy load, the meter on the galxy is not working. Did I lose all power?


You appear to be aware of you antenna system with the separate meter attached so the tells me you dont punish a radio with an high swr. I am just guessing red wire/solder in mic cord at plug given that it is a side mic mic jack.
Stock mic

DX 2547 Only transmitting at 1 watt and swinging backwards on the power on high side from 4 watts to 1 watt.


Check the SWR reading on your antenna. If you have the wrong adjustment here, it is like having the wrong antenna, or none at all. You will need a SWR Meter, and somebody who knows what he/she is doing to help you.

This radio has swr meter


S.W.R == Standing Wave Ratio, this is a Relative measurement of the Amount of Power Going UP the Antenna, Versus the Amount of power being "Reflected" Down, the Antenna. This ratio, is displayed, as a reading on the meter. Also Often this SWR meter is dual used as an "S" Meter, this is used ti display relative signal levels from other transmitters. and is shown, as an "S" Scale. 0 - 9 on the meter.

Random power out indications


Your antenna is not tuned for Lowest SWR. The higher the SWR the less power you put out.

It needs to be tuned to the center of the band. Channel 19 or 20. an SWR of 2 is not that good. You should not go over 1.5. Idealely it should be as low as possible. My antenna is tuned so that my SWR is 1.0 on every channel.

So on channel 1 your SWR is high, so it puts out less power. Some what better on channel 20. And your SWR is lowest on channel 40, thus it gets out better.

You want to get the SWR on channels 1 and 40 the same. You need to know whether or not the antenna is too long or short.

Tune to channel 1 take a reading. Take note of it. Then do the same one channel 40.

If the reading is higher on 40 then on 1 your antenna is too long and you need to make it shorter. if its higher on 1 then on 40, its too short so make it longer. When you get to the point when the SWR on 1 and 40 is about the same, you about as good as you are going to get with the meter in the radio, and you will see that on channel 20 your SWR will be very low, and it will be your best channel, and you will also see that you put out about the same wattage on all channels.

Well,some meters are set different than others,to see what is going on,you need a good WATT-SWR meter,but that is not a bad reading of SWR, you can get one at Radio Shack. You can not go by the meter that is on the radio,it,s probably not set right. hope this helps..

RG 66,99,DX2517 Replace Q54 2SB754 60watt 7A with a higher power 2SB817 100 Watt 12A. Derating of this component will cool operation, provide better voltage stability,decrease wobble, allow voltage increase to 14.5 volts comfortably. (replace 10 volt caps in this section of the radio to a minimum of 16 volts before increasing supply voltage to this level)and provide faster swing rise time, Replace Q37 2SA473 to a 2SA1012-0 or ECG153 this will improve the clarity and volume of the modulation and it will also run a lot cooler.

It transmits off frequency is there a adjustment and also the frequency counter goes crazy at times


To add 10Khz to your transmit frequency:

FIXED/OFF/+10KHz SWITCH:
The left position puts the radio on
one of the three fixed channels that is selected by the channel switch
(6,19, or 21). This over-rides the channel selected by the 40 channel
knob. The right position adds 10KHz to whatever frequency you are ON.
In the middle, both features are OFF.

Otherwise, a radio tech would be able to retune the frequency inside the radio.

After adding 10KHz to your frequency, use the SWR control to check the SWR of your antenna.
Here's how:
SWR CAL CONTROL: Normally this switch is set to “PO”. Then,
during transmission, the meter indicates output power. To read SWR,
rotate this knob during transmission until the needle moves to the “SET”
point on the SWR scale. Then, while still transmitting, set the R.B./SWR
switch to SWR.

Ideal SWR is 1 but you'll want to be as near one as possible. An SWR of 1.6 or greater will make ineffective use of your antenna.
If in doubt, a radio tech has the required meters and tools to adjust the SWR/Tuning of your antenna.

Radio will transmit some of the time


THAT IS A VERY GOOD SIGN THAT YOUR SWR MATCH IS OFF....I DONT KNOW IF YOU MATCHED UP YOUR RADIO WITH YOUR ANT.IF NOT YOU CAN BUY A CHEAP SWR METER @ RADIO SHACK...CHECK THAT YOUR COAX CABLE IS OK TRY TO REPLACE THE COAX......GOOD LUCK

CB transmission


Hello 64driver,

Make sure the radio is grounded properly and that the SWR is around 1.2:1, 1.3:1 is good but try to get it to 1.2:1. Also take a power output reading while keying the mic. To do this with your power meter put it in-line with the CB and your antenna and key the mic you should get about 4 to 5 watts PEP. If this is the case your unit is putting out the proper power level, if not have the power amplifier checked by a qualified repair shop.

I hope this helps
