I would send it back to the dealer, if you are not happy with it and get them to sort it out if you do know what you are doing. I have SS158EDX which I obtained from Truck King some five months and it has been just fine. Four guys I know obtained theirs from Truck King and have been very happy. You ...

D69 is not just a diode.
It a 7.5 volt 500mw zener diode.
It the same diode i had go bad in my cobra.

Rick from Euro radio co put me on to theirs mosfets about 5 years ago. When he converted my Cobra 148GTL-DX with them i seam to remember he change many caps and some resistors and rework a coil. I have been using the rig most days for the past 5 years mobile with on trouble, the output on FM is just...

Chevin

I had a Cobra 148GTL-DX with low RX on AM and FM.
It was a bad diode in the main 8 volt voltage regluator.
The voltage was to high.

Chevin.

Chevin

The RM3 is not a IRF520 but may work with lower power output.
The amp maker removers the ID from the transistor making hard to find out what they are.
The right mosfet is HUF7534P3 and are made by Fairchild.

Got my dx95 back from Rick a few days ago and its now working AOK.

Chevin

Can someone help I have a new DX95T2. When the rig has been on for a while the receive signal starts to drop. My friend which lives about 4 miles away always gives me +40 on my DX88 but on the DX95 it starts out at about +40 but after about 45 minutes its starts to drop and after 120 minutes later i...

Chevin

I have always had very good help from Rick and he has sort out more radios of me and my mates over the years and I have never need to take a job back. One good example is an cobra 148gtl-dx which had been to 6 so called radio repairs and each one told me it had to many faults. Well I give to Rick an...

Chevin

Try replacing the balance modulator, this is an all too common problem with the new type BM chip. Do not try to replace it with the old type BM (AN612) as it will not work without changing components. I am sorry I could not repair the radio for you as I have lots of work at this time. You was right...

Superstar 158EDX PCB EPT690010D PLL MC145106 The trouble is low audio no SSB I can only get about 4 watts but AM/FM is ok 10 watts and nice and loud. I have tried adjusting the ALC but make no difference and there is a bit of a carrier on SSB about 1/8 watt. Can anyone help? I would Rick to fix it b...

You alway get one. May be he did not get the help he wanted.

Chevin

Thanks Defpom. I have e-mailed the guy but had no reply.

Chevin

Anyone with PLL board or just the MPU chip will do for a Lincoln. Rick in the UK is trying to repair my Lincoln but it needs the board or MPU chip Rick was promised by some on this forum he could have junk rig in a swap Rick is now out of pocket on the deal but some people are not what they same to ...

Chevin

Rick knows is stuff all right its just amazing how much he knows. some of you may know that he is also active on 5 more forums. I think he genuinely likes helping people it is a rare to find some one like this in the modern world. He also plays a mean guitar. Keep on rocking Rick.

Have you tried asking Rick? You would need to give a full description of what your fault is along with what you have tried to sort the fault out.

Hi ramblingman change ic312 5 volt regulator and c393 1000uF capacitor and all the resistors + diodes around ic312 but the problem is still the same. I have found if you hold the channel up or down in the display flashes on and off. The fault must be on the processors board as I have just tried one ...

Chevin

i have got Lincoln off eBay i know its not the best place to buy a radio but it was cheap. The problem is there is no display and will not TX or RX. i have check all the voltage regulators and there are all ok with the right voltage coming out of them the big chip on the pll board has very low volts...

Chevin

Anyone know where i can obtain an LA1195 Audio amp.

Chevin.

Chevin

A relay can only stay engage if it has positive volts on one side of the coil and ground or negative on the other side. If the emf diode was faulty then it would not deactivate very quickly due to the coil ringing. Other problems you can get with relays are the reset spring can become weak. The easy...

Chevin

And what is this all about?

Chevin.

Chevin

I had one of there rig some 20 + years ago. I had it converted to 160 channel by Rick.

Chevin

Thank for the help Rick. as usual you was spot on. i found tr23 open circuit.

Paul (aka Chevin).

Hi ramblingman change c32 and most of the caps which go to ic-1 but the fault is still there I would normally get this sort of fault fixed by Rick of euro radio co but he tell me he has so much work on he can not do it for at least 6 weeks. So can anyone else help?

Can someone help i have a Galaxy DX88HL with no receive when on AM but the signal meter shows it is receiving but no audio it works just fine on FM and SSB

Chevin.

Chevin

Check the transistor like Rick suggested and found tr36 with 920 ohms between base to emitter. I could not find a 2SB525 so I have used a BC640 which is 1 amp 80 volts. I think this transistor will be ok. Rick can you let me know if this is ok to use this transistor. I got this Superstar 3900 from a...

Chevin

Can anyone help with my SS3900 PCB #EPT360014B PLL #MC145106P. The problem I have is feedback on FM RX and the same on SSB TX/RX. I have replaced the Mic Op-Amp IC4 and most of the caps around the Mic Op-Amp but this has made any difference to the problem.

Bret (AKA Chevin).

Anyone hear how Rick is getting on? I was told by ham friend he was going in hospital for an op.

If you do not say thank you for previous help you will get ignored. It?s not to much to ask.

Can anyone tell me where i can get a circuit diagram for the revision 2 of the cobra 200gtl dx. as my one only has a kcs shift of 3khz and i have been told they have sorted this out on the revision 2 model.

thank Chevin.

Chevin

i sent my radio to Rick at euro radio co and he sort it out at a very good price. Thanks Rick once again.

Chevin

have a look on www.open-channel.co.uk

Chevin

Can any one help me with the hardware which go round the channel switch the bracket and 2 boards 1 for the display and the bottom 1 where the wires come from the pll to the switch, I also need a sig/rf meter.

Chevin

Thank your your help Dave try to phone you but you was on the phone. I am getting a new switch off Rick i think he is your mate, very helpful chap he sort out my problem with my rci 2950 he put me right on the part to change.
