Galaxy DX 88 HL jumping frequency

As the title says, I have a DX 88 HL that I just picked up that the frequency counter constantly jumps around on. It has no recieve, but I haven't tried transmit since it doesn't appear to be stable. There does appear to be a black block looking component that is located on the pcb underneath and slightly behind the frequency counter box that appears to be slightly burnt and there's a ground strap running from the frequency counter box to a pod on the board that is broken. I'm sure the ground strap needs resoldered, but I'm not sure what the black box compenent is.. I can't say I'm a master technician by any means, but with a little guidance, I'm competent enough to replace some parts if I know what I'm replacing. Any ideas what this component could be?

    Ok, I got this sorted out. It apparently takes a little longer than normal to stabilize during warm up. Typical Galaxy in that aspect. Radio works fine.

    I also have the problem of the frequency jumping around but this happens when I keyup?

    Mine has the same problem. Did you happen to get yours fixed?

    Mine works fine after it warms up. When I first posted it, I didn't let it run more than a couple minutes to try it, but after it's on for about a minute it stabilizes fine. The problem is only with the frequency counter, the radio itself is on frequency fine on transmit and recieve.

I had this problem on an 88 and it was the one of the 4008 adder chips gone bad. Not easy to replace. Needs a good tech with a steady hand and hot solder gun!

Just want to know where to set all the bottoms on this Galaxy DX44 V to be ableto talk to people on channel 19


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.

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


sounds like a connection is coming loose inside. take it to a CB shop and see if they can spot it. Should be an easy fix, no more than 20 or 30 dollars

Dx-88 HL


You'll need to take it to a repair shop. Because it transmits its under FCC rules so a certified tech needs to work on it.

Or take it back to where you got it and have them correct the problem.
