Wanted to share some info with everyone in case someone comes across this problem with an older style Connex or Galaxy.
When you turn the radio on "Cold" and key the mic the frequency is off by 10 KHz and once the radio warms up it will go back on normal frequency.
Check X2 Crystal 14.010...
You guys got to see this monster!
It is a Galaxy 88 that someone hacked and installed a pill inside. I can not see which pill it is but looks like a 455. Sucker swings 130 + watts.
Thought you guys would love this one.
I wanted to give you guys a heads up on the newer Cobra 25 LTD Classics that have the TDA 2003 audio chip in them.
If you get one in that has no audio output but has a good carrier along with no RX from the speaker but the meter is showing it is receiving plus no audio on PA you would think the...
Does anyone by chance have the schematic for the EPTDX2912Z board?
This is what they are using in the Galaxy 66V2 radios and I can not find any info on it.
I seen someone say the DX98VHP was the same board but it is not the same!!
Thanks in advance for any info.
Anyone ever had a cobra 29 LTD Classic Sound tracker that would not receive until it warms up?
No matter what you do to it it will not receive until at least 4 or 5 min warm up time then it just pops on and will work the rest of the day with not problems.
This happens each and every morning...
Had a brand new Cobra 29 Classic that was only two weeks old died.
There was no TX or RX not even a nudge on the meter showing any kind of life!
Light did change from green to red when keyed.
Went through the whole radio tracing down the problem and everything was checking out good up to L22...

Parts needed:
8- 100 Ohm 2 watt carbon film resistors
1- Small piece of RG8 50 Ohm coax
1- Small piece of pref board. Not needed but looks better.
1- Med bottle, Or what ever you want to put it in.
1- PL259, I have a quick connector...
Had an old Galaxy 919 DX laying around that would not transmit. The light would turn from green to red when keyed up but no TX power. It will not transmit no wattage to the watt meter but it does have enough RF to make the freq counter lite up. On channel 20 I get 26.750.
All the voltages check...
I done a search on this problem on this site and did not find any info about this issue so thought it would be nice to share some info how what the problem could be. I talked to Andy after I repaired this problem to see if he would like to make us some of his cool graphics to help others...
Hey guys, I have a connex on the bench that has a problem that I have never seen before. Lets say your on channel 20 = 27.205 when you change the channel to say 24 the frequency jumps to 27.415 and will not change to the correct frequency until you turn the power off and back on then everything...
Would anyone by chance have a Magnum S-380 laying around that I can get a picture of the bottom side of the board? I need a close up pic of the bottom side of board behind the channel display side of the radio just past the three shield plates.
Thank you.
Came across this while surfing the net. Seems to be a cool idea to pump it up some.
I built one of the old style type like Buddy has but the volume is a bit low so this just one just might do the trick.
Hey guys I need some help!
I really hate asking for help but this radio has just about made me check into the nut house!
I have a Cobra 29 LTD NW that has no RX what so ever. No RX/ S meter reading as well.
Radio was receiving ok I thought but the transmit was off frequency.
I found 10.240...
I have a Dak Mark X S.S.B. radio that lights up but does not work.
If anyone wants it you can have it for free. Just pay the shipping cost to get it to you.
Keep in mind this thing is huge and weighs a ton.
Need some thoughts on this 60 MHz PC unit for the test bench.
