I like challenges. I am looking for something , I would like to fix a totally wiped out Galaxy Mobile or Base. Place your story on the Forum and if I select you , it will be a free-bee on me. It must be INTACT , CLEAN and all the parts still in it as if it never had trouble. Smoked parts a plus. No damage to the face plate or case. No job to bad. Lets go people. |

I've got a galaxy 2517 that was "turbo-tuned" (yes, I fell for EEI's ruse) After only a month, there is a problem with AM modulation....Using the modulation meter on my Astatic 600, it is showing 50-60 percent modulation with a dead key.
It is not the microphone, because I put the stock mic back on it (was using supersidebander), and same results. SSB is ok. I'd like to have someone qualified check it out, and see what exactly they did to it....Did they really beef up some components, as they claim? or did they just peak it so much that it looks good on a watt meter? (but probably overuned to produce harmonics and intermod products) I suppose this doesn't qualify as 'totally wiped out', but I sure would like to know the truth behind the hype...Others would surely benefit from this knowledge as well... |

Hi , David , sorry to hear about your trouble with the Super Dooper Turbo Tune. As for the components changed? I doubt it. As for peaking it out to look good on a meter , you got it. I can take that radio and by shorting out "1" capacitor make it swing 150 watts on your meter. Yes it is true. You see meters like DOSY (although nothing wrong with them when used correctly) and other types just love DC voltage. They suck it up. Did you ever hook a 9 volt battery to your DOSY? The darn thing swings to 1000 watts plus. Well what happens is exactly what you said , they clip and flat top the envelope so much that it tends to create DC out of the RF sinusoidal pattern. When this happens , small spikes form on the flat topped areas which are harmonics coupled in from the DC. This when presented to a power meter looks really good as far as false power. The TRUE way to do a peak is to maximize the carrier and still have the drive to modulate it 100% without flat-topping and clipping. As for your problem , Am I understanding you correct , with a supposed DEAD KEY you are seeing modulation , like an oscillation? |

Yes, when in AM mode, just keying the mic is showing between 40-and 55 % modulation...This changes when you switch the meter from avg to peak power readings. It appears higher when you select avg power. Even with the radio mic gain knob all the way off...it is constant. This happened late the other night, and I couldnt get any on the air reports to help diagnose it...I also don't want to make things worse, so I just packed it up in its original carton for right now...good thing I have my 2950 for a backup....that is I did until my Pyramid 25 amp p.s. went haywire!!!it appears to have lost its voltage regulation...I don't think the 2950 wants 30 volts!!!! On top of all this, I'm having antenna issues, too...When it rains it pours, I guess. Not to worry, though...I'll get things straightened out eventually.
I want to get the galaxy fixed, but I need to know its going to someone who can do it up right so it will last....I'm in east central illinois, and I havent found anyone local yet...it is under warranty, but the shipping costs could end up being more than the repair...Like I said, I'd really like to know just what EEI did to it, and if they really do change any parts....This information could potentially help alot of people who are getting taken in by all that jazz over there....It has been an eye-opener for me, thats for sure...
Ill say this, though...until it broke, I sure was getting flowers left and right... |

i have a galaxy 2100 that is off freq on ssb i have not touched it and it is very clean! i also have another that is nicer than the first but the frequency counter does not work on it! i bought both of these radios assuming that they worked and got ripped off twice! i love the 2100 galaxy's becuase of the silver face, it is my favorite radio but i cannot find one that works so i have given up! also i canot find anyone to work on these radios, if you could help they would be projects i promise! thanks, chris |

Chris , I may be able to help you here. The counter problem is the diode (1N4003) right in front of the 5 volt regulator (7905) inside the frequency counter module. Replace them both. You can get parts at Radio Shack. The SSB off frequency can be fixed by slightly moving L27 for USB and L28 for LSB. Tune L27 when looking at TP-6 (R-102)with a frequency counter for a reading of 10.6925 Mhz. Tune L28 when looking at TP-6 (R-102) for a reading of 10.6975 Mhz. This is most likely the problem. Then tweek VR-15 while transmitting into a known on frequency radio to the point where you sound perfect. This is not very easy and I skipped some steps , however it should get you close. |

You won't have trouble either , Bondo , Most other CB places are just trying to win business. Thats ok though because all the bashing does not affect the some 30 thousand that have been regular at Copper. It will never change. Believe it or not , I was buying things from Copper for over 17 years now BEFORE I started to work with them...NEVER had a problem. |

I have a galaxy 959 with extra channels it ran fine until I let a friend borrow it and once he hooked it up in his car it got stuck on one channel the channel display changes but not the freq counter it only works on that one channel anyone have any ideas on what it can be??? |

Bondo--EEI are selling snake-oil--I don't know if you follow the forum over there, but check it out if you haven't yet---watch what happens if anyone asks them to back up their outrageous claims, or suggests that they have a customer service / trust problem. Oh yeah, don't mention any other product line worldwide that they don't sell--just the name "dave-made" gives 'em fits...They act like they're all on meth, or something. lol...I was known as highlander there until I got banned. My "turbo-tuned" galaxy did half what they claimed it would do output-wise (not that that is a big deal in itself) It broke after less than 30 days. Other dealers have seen their stuff come through to be repaired...they said that sometimes a turbo tune means the pots were all turned up to the max (not good) and the mod limiter was clipped (worse). They don't seem to realize that people are figuring out their game in rapid numbers now.
Im partly responsible for my own predicament, by not researching them a little bit more before buying, but when I get burned, I tend to spread news of my dissatisfaction. |

I have the old model RCI 2950 I stupidly hooked up backwards after runing new power wires in my truck.The radio shack only had red wire sooooo I guess you can figure out the rest. Anyway It fried the protetion doide and about 10 more parts throughtout the board.I almost cried.I have had this radio for about 6 years.This should be a good one for you |

Thunerbolt, I did that too one time, don't feel bad. There's one big electrolitic capacitor in the rear of the radio near the power connections. Did you change it. That's what blew when I croosed a wire.

ok, heres one. while moving from where i was to where i am now, i packed my radios into boxes along wih a few other things. in the boxes with my radios i had a can of wd 40. top not on it. during transit, the wd 40 leaked out and got on, and in a couple of them. one, a pc 76 xl. it will not receive, or transmit unless you use a blow dryer to heat the radio up on the inside. after you do so, the radio works fine.it will stay on for days, but if you turn the radio off for a couple of hours it stops receiving and transmitting again. if you heat it up for a minute with the blow dryer it starts to work again. i have blown it out with a air hose, but that doesnt help. any suggestions? |

ok, you like challenges, i have a euro 3900 that at first had a short in it somewhere. sometimes it would transmit, and receive, sometimes it wouldnt. i had someone look at it that told me they knew a little bit about radios. i was told that they used a small screwdriver to go accross the legs of the finals while the radio was on. also accross the audio chip, and across other parts with legs while the radio was on. now it is dead. got your work cut out for you on this one im afraid!!! if you can remedy this, i would call ya god. |

My neighbor has a Uniden Grant XL and it was box stock and he took it to a newly opened local CB shop for a peak up. He gets it back and the radio sounds good and loud for being barefoot. The only problem that he has noticed was the back of the radio gets HOT real fast. I was listening to him on my base and he dropped out suddenly. He calls me on the cell phone and says the radio turns on and doesn't receive or transmit. He takes it back to the shop and the "Tech" installs a new final and tells him that a 1.7 to 1 SWR is causing the radio to heat up. Strange the radio wasn't heating up before the "Tune UP". Sounds to me like a few extra things were tweaked. |

i agree with 181 most radios will withstand 2:1 miss matches without damage sounds like your tech needs more training in how to understand the ICAS VER CCS rateings of finals and a good course in heat transfure. |

Hey Toid tell your tech to give us all a break. What has evidentally happened is he has turned up the voltage on the drive transistor and the output transistor in which he messed with the final bias pots. Also he needs to make sure the transistors are getting properly heat transfer to the chasis. |

Well ya see guy's the simple salutation to this problem. You should have bought the radio's from (COPPER) and there would be no problem's. No blown up^ radio's and off frequency and you would have a great DXing radio. And geat service. 73's Len # 111 So Minnesota. |

I ALSO PURCHASED 2 MOBILE GALAXY AMPS FROM EEI AND THEY ARE BOTH GARBAGE,SHOULD SEND THEM BACK BUT I WILL CHALK THIS UP TO EXPERIENCE, IF I NEED ANYTHING I WILL STICK WITH COPPER. |

I've got the story to top all on this post. This all starts last week on Tuesday (8-29-01). I order a brand new President Lincoln and a chip switch from a place in CA. Ok so no big deal I get it on Friday (8-31-01). I plug it in and make sure the radio works and it does so I install the chip switch in it. Well I used to work for a big electronic firm that everyone should know as a soldering/cell phone tech. I get the new chip switch soldered in there and make sure everything looks as good if not better than the factory work. I get every thing plugged back in place like it was and get the covers back on as normal. Now the fun begins. I turn it on and the hr2510 pops up on the display like it should and get it switched over to the lincoln setup. Everything seems great so I get all the settings programmed up and things are looking awesome. "Oh man, I can't wait to get talking!" Well I go to key up and what gets displayed??? Error #3! PLL will not lock at that Frequency. WTF!!! I switch channels and try again. WTF it's still Error #3! I go to switch frequencies again and the display craps out on me and shows the hr 2510 setup display again. I figure it's the chip switch being loose or the solder not flowing up to contact the two sided connection holes so I try all saturday to get things working right. Well after working on it for 6 hours things are still messed up and even worse I detected a popping/crackle like a leaky cap or bad voltage reg. on this new radio. Talk about basket case straight from the depths of dispair. I wish copper sold the President line... I know one thing for sure. I would not be having these problems right now if I did. Chalk up 400 dollars down the tube and one shop that I will never order another thing from.

david I'll keep this updated. As of right now the radio will show the correct freq. but will not lock for transmit or receive. It sure looks cool though. Hopefully 307 has some ideas for me to check. I know where to get another one if it comes down to really taking that huge loss. I'd rather just have someone fix it. 307 will you look at this lincoln even though it has a chipswitch? Just incase anyone want's to email me my address is (sanddiegoduner@aol.com). Thanks everyone specially copper for having this great forum.

Ok, here it is! I have a 2510 that I inquired about on this forum. The radio has no sound to the speaker. I have replaced the speaker, the audio IC chip, and the jumper plug on the rear of the radio. I have had the radio at two service shops, one telling me it was beyond repair, one telling me $180 would fix it.Everything works fine, meters, frequency display,transmit and even recieve, just no sound to the speaker. |

Mitch will the radio work with an external speaker? If not it could be the PLL not locking on receive. It's sort of the same problem I'm having but mine will not lock TX or RX. Will your radio RX in any setting (FM, AM, SSB)? If you turn off the noise blanker can you hear anything?

Sorry to hear about your Lincoln woes...Curious, though...if you checked the radio *BEFORE* you did anything to it, and it all worked (Xmit and RCV), maybe you just either got a bum chipswitch, or maybe a connector worked its way loose in the dismantling/ reassembling process...
If its just a bad chipswitch, your only out 60 bucks...
Mitch-Sorry I never replied back to ya in your other thread...I am in TN, and don't know of any techs in CO. I wish you the best. If you do have access to an oscope, I will be glad to help you "signal trace" the radio...Would take some time, but if worse comes to worse...
When I bought my 2510 back in 93( from Copper ), I did the 11 meter mod on it. Eventually I did put in a Chipswitch. I used the socket for the chipswitch as well. I know there is no real reason for the socket, because you almost always destroy the origional microprocessor when taking it out, but I did so *just in case* I ever had to replace the chipswitch. You know how it goes though...if you anticipate it-it will never happen; if you don't, it will.
Anyway, just to share my experience, I have never experienced any problems with my chip "wiggling" loose out of the socket like some people are worried about...In hinesight-I am glad I put the socket it...just in case...
Right now I am rebuilding an old style Lincoln (that used the MRF477 final) I picked up on Ebay as a parts radio. I am about 90% done (the radio was BADLY buchered)...
The final and driver were missing, amoung the many clipped or missing diodes, resistors, and wires...I got all the parts from Uniden, BUT the final is not available from them. It is from RFParts, but at a hefty cost. Anyway, I am going to use a MRF455 instead. I have laid out a PCB to mount the 455 on. I am making a photomaster, and am thinking about having quite a few of these boards made up. If the radio all works out like I expect it to, I am just curious how many people would be interested in a "kit" to change their bad finals with a more readily available one? I am still about 2-3 weeks out from having my boards made, but just curious if anyone has any interest...
Thanks,
Alan |

Paul, mine has no sound period! Not with the internal speaker, nor an external. No voltage there. The signal meter shows recieve, it transmits fine, (at least on ssb, i did not try am), the rig looks like new, no mods or anything. I paid $40 for the first diagnosis (beyond repair) the second shop has the radio now, either I pay $180 to have them fix it, or pay $35 and pick it up broken. I may just let them keep it! |

Well Firebird, I do not have access to a scope and if it does not have a mic, I would not know what to do with it. The shop that has the radio right now claims that a voltage regulator went out causing three chips do go. I had the audio chip replaced prior to this diagnosis so who knows. But I am not going to pay $180 to fix a radio I can buy all day long on the net for $150. I may pay for the diagnosis ($35) get it back and keep it for a parts rig. (I use the same radio in my car and I have a 2600 in my truck. |

I bought a texas ranger base, turbo tuned from EEI less then a year ago. There repair add states no repairs will be made unless approved by owner first. I sent my radio there they installed new parts and then notified me that didn't fix my radio problem, and it was total loss, which i figured since lightening hit my antron 99. But they wanted 50.00 before they would send my radio back, but after i reminded them about the add, they said they would sen it back for only shipping cost. I have failed to recieve my radio yet. |

Mitch I would buy it from you if your willing to sell it. Have you checked the web for the specs on the board? I don't have the proper tools to check everything out but I copied all the info I could about tuning this thing up. I do have access to the proper equipment but getting time to get over there and use it is the hard thing for me. Shoot me an email on the email listed above about your radio. If you want I could email you the info I have found.

Well since I haven't updated this for a while... My lincoln is still out of comission. Everything works except for the receive and transmit. The PLL is not locking. All other buttons work just fine. The place of purchase is not any help and they should not be getting anyone's business from this forum. Trust me everyone stick with Copper. They are the best I've ever purchased from.

I'm hoping someone can help me out here. I need to know the EXACT lengths that the coaxial leads are that come out of the control box (the one that goes up on the mast) on the old Superscanners. I sustained a lightning hit during tropical storm Gabrielle and need to rebuild the relay box. Any help from any of the techs would be appreciated. |

Jason,
Just in case the techs here can't help, try looking on eBay. There is at least one whole (complete) Super Scanner for auction there:
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1275991654
and to view a control box,
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1275693238
And someone is usually auctioning copies of Super Scanner manuals. The manual MAY indicate the lengths of the coax connecting the relay box to each element. Be sure to ask the seller if the manual indicates these lengths BEFORE you place any bid!
Try:
http://cgi.ebay.com/aw-cgi/eBayISAPI.dll?ViewItem&item=1275118731
and maybe,

I have a HR 2501 that I bought from a guy in Miss. He said it was in fine shape and had just beem repaired. I got it and it keyed up but sounds really bad. I bought a chipswitch for it because the tech I took it to said that the original chip was most likely the problem. After I got the chip and took it back he said he couldn't get the original off because it was covered with goo. I suspect thats done at the factory to keep you from messing with it. Any now I have a pefectly new chipswitch and 2510 that has really scratchy, fuzzy , almost unintelligible transmit. I tried a different 2501 mic to no avail. This thing looks like it had an echo installed at one time. I haven't been able to find anyone around San Antonio TX that will touch anything but a regular 40 channel radio. Everything inside the radio looks ok. |

307, I have a Galaxy 44 that is less that 6 months old. I think lightning may have done a number on the unit. I opened it up and have several burnt caps and a few diodes near the final section. Several parts would have to be replaced, just to get it looking normal. It will not tx. and very little rx. I hooked it up, and keyed it with a base nearby. The nearby base shows a key of maybe 2 to 3 s-units, but no audio. This is a brand new unit with no parts removed ( other than tr 32 removed for mod) just fried. Can you help? - |
