I don't know which one it is

perrym1962

I bought a non working Uniden 980ssb radio and I think the reverse polarity diode is blown because it blows the fuse every time it is powered up. Probably a long shot and no schematic is available for these that I know of. Thanks....

Radio Make and Model: Galaxy dx949 PCB Number: EPT069610Z PLL Number: RCI-8719 Test gear available: limited, volt-ohm meter- solder pencil, basic.. Symptoms: Just purchased, 3 yrs old but got it brand new never taken out of box. Turned up vr16 for more modulation, not clipped. Was doing in the 20 wa...

Anyone know how to put variable dead key wattage in a Cobra 29 XLR? I have done this mod in several other types, but can't find any info on this particular radio..

perrym1962

I did it to suit me. I don't really care if anyone else "approves"...

perrym1962

All I know is I put a galaxy a kit in a 146 that I had. It yielded 40 low channels and 40 upper channels. The instructions came with it and was fairly simple.. I did not try ssb, but on the am side worked perfectly..

perrym1962

If you can find one, a galaxy A kit will work in them. Also a expo 100 "N" kit will work in it. But the problem is finding them.

perrym1962

I have had a couple of them and the channel mods work the same as with the older ones..

Radio Make and Model: Galaxy dx99v PCB Number: EPT360014B PLL Number: MC145106P Test gear available: Symptoms: Frequency display will light up when first powered up, but the 1st and 4th number will flicker out in a few seconds. What is working: Everything else is fine. What has been tried: Nothing a...

perrym1962

I didn't have a 104 so I came up with a 103. Took care of the problem. Again thanks for your time and solution. Works great. Perry....

perrym1962

I appreciate your reply. I will try that this weekend, and let you know the outcome. Thanks, Perry in Ky..

perrym1962

I have a fairly new Cobra 29ltd chrome. When you turn up the squelch just enough for the noise to go away there is a fluttering sound in the receive. You can turn it on up more and it goes away, but a weaker signal will get cut out. I have had other newer 29's that did this as well.

perrym1962

Never mind it has been taken care of....

perrym1962

I have a palomar lizard 250hd with the automatic sideband. On am when in use and you unkey there is maybe a 1 second delay before the receive comes back. Is there any one that may know a way to disable this function?

perrym1962

I recently acquired a Cobra 138xlr and for whatever reason someone removed all the wires from the squelch control. Just wanting to know if anyone knows the precise location to re-solder 3 wires back to the pcb so I can have the squelch function back intact. I have saw the schematic, but I am not an ...

perrym1962

Sorry I meant to say L37, not L8. Anyway it wasn't that either because went out again and I pushed gently on the pc board and it is what I am fairly sure is a cold solder joint. So without knowing which joint it actually was I started reheating. Slow process but so far it is still working. I guess t...

perrym1962

I just messed with it again I started touching components with a small plastic tip tuning stick. I touched L8 and moved it a bit and it started working. Does this sound crazy? I don't know? Guess I will try it for a while and see what happens. I appreciate your time and hope I haven't wasted it. Cra...

Pin 8 of IC4 shows 8.36 volts in TX mode. Driver voltage on collector in TX mode on am is 3.83 volts and on LSB is 13.2 volts. Final voltage on collector in TX mode is 3.93 volts on am and 13.32 on LSB. Radio was keyed maybe 5 seconds when I noticed my error.

perrym1962

Base of driver is 1.22v, base of final is .79v. I am not positive which is IC4, but with component side up with front of radio facing me there are 2 ic's on the right which maybe one of these is ic4. Cannot find a marking. Assuming pin 1 is toward the front of the radio pin 8 of the one toward the b...

Help...

perrym1962

I have a 1992 Cobra 148gtl made in Philippines radio. I accidently keyed the radio with the antenna unhooked. Now I do not have any transmit, receive worked fine needless to say. I replaced 2sc2166 and 2sc1969 with 2 out of another radio that I know are good just to see if that is the problem, but s...

perrym1962

I wasn't trying to push anything on anyone. I was just telling my experience with the ones I have. If anyone does not want them that is great. I don't care, that is your right. Happy holidays...

perrym1962

Sounds great...

perrym1962

If you have never owned one then you don't know for sure. I hear lots of things, but I don't believe everything I hear. Of course thats just my opinion and I have 2 of them with "0" problems.....

perrym1962

I have 3 older ones and 2 newer ones. Of course I like the old ones better, but I really cannot find serious fault with either of the newer ones. I use them on sideband as well as AM and they do fine for me. So I don't know?...... p.s. I did channel mods on both, variable wattage along with the diod...

perrym1962

Yeah, glad I could help a bit. I don't know a lot about radios, just a little here and there.Perry....

perrym1962

Yes on the 11.3258 xtal. I think the new ones have the RCI8719 pll. I have done the channel conversion on a couple of them and they channel the same way as my old ones. I did notice that on the x-tra freqs. below channel 1 with the old ones (148gtls) freq. 26.9550 is on channel 13 and channel 27. On...

perrym1962

Go to the modification pages on this site and go to the galaxy 949, 959 section. Has a lot of good mods. Super swing mod and all. I have tried it and it works well. http://www.radiomods.co.nz/ Click on this link and go to Cb and Amateur section, click on modifications tab, scroll down to the Galaxy ...

perrym1962

I'm not trying to be rude, but I have had a couple of 18 ultra's and they are pretty much junk. I guess it would beat nothing at all for a short time till you could find something else.. :roll: Also the loose connection should be an easy fix. Tighten the nut on the so-39 where the coax screws on. Ca...

perrym1962

I guess I have led a sheltered life. I have never heard of a cobra made in Panama. I not saying there wasn't, I just have never heard of it.

perrym1962

The Voyage VR9000 I had after turning up the mod and doing the diode swing trick had more than enough bang without messing with the 2030. It would hit about 40 watts on Dosy Meter. I know they are not scientific or anything, but close. Also had super audio.

perrym1962

The adjustments are the same as the 77,88 and 99, 2980, Saturn, etc. Everything is not "exactly the same", but almost.

try this...

perrym1962

Sure will. I just did one not too long ago and worked great and the frequency counter was right on...

perrym1962

I have never heard of a ssb conversion for a cb. I am sure there are super tech's who can do it, but I have never heard of it. Of course I lead a fairly sheltered life...

perrym1962

I hooked it up as you said and it worked like a charm. Thanks again, Perry...

perrym1962

The board looks to me the same as the 2517, 95t, etc. Should be a nice radio..

perrym1962

Thank you for your response and your time. Greatly appreciated. Perry

perrym1962

I have a good bad and ugly noise toy. It has red, black, white and green wires. Just wondering if anyone knows how to hook it up. Someone gave it to me and did not have the wiring configuration for it. Thanks, Perry..

perrym1962

That took care of it. Thank's Rick and I do appreciate your time..

perrym1962

It is marked Q28 which I am sure is the same. I will find another one and try this. Thank you for your time..

PB-208ad is the only # I can see..

perrym1962

I have a grant lt that I did the pll conversion on. Radio works perfectly except for the channel display. I touched a trace with the solder pen in the area between the pll and the channel selector ribbon and the display went very dim and then went out. I replaced the led but that is not the problem....

perrym1962

Same as the 148gtl. I appreciate your time. Thanks..

perrym1962

P.S. I have lots of friends....

perrym1962

I was talking about sliding 10 khz to get 3a, 7a, 11a, 15a, 19a. I'm sorry for asking. Later....

perrym1962

Pick up the in between channels

perrym1962

Is it possible to unlock the clarifier in this am only radio? I have found the mod for the ssb models but not these.

perrym1962

From my experience (which is not extensive) I have saw hardly no Royce radios that you could get extra channels in.

perrym1962

Sold radio to someone else. Thought I would let someone else mess with it . Thank's
