Re: Superstar 3900G or 148GTL/DX
Sammy or Claude, I purchased a mic for the Cobra 25 Ltd, a Superstar DM507-4, for the cobra radios. However, I'm not certain if the pin code is correct. I've always done the soldering of the wires to pins by color. I Google this and I got schematics showing names of the function; tx, audio lead, shield, receive, but the wires have colors. And I doubt one color is always asigned to that particular function?
This mic's pins are: 1- shield, 2- white, 3- red, 4- black. Would this be correct for this Cobra 25?
Thanks again,
John

Don't know John . Shield is shield obviously . White is usually audio . Use a multimeter on the red and black ones to find out which one is TX . When you key the mic the shield and red or black will give continuity . That's your TX . The other one will be RX .

Don't want to give you all the answers. It's all part of the learning curve

Re: Superstar 3900G or 148GTL/DX
Good morning Guys, I've a question about power supply. I have (see photo) a 13.8v 7 to 10amp PS. But when I connect radio to it and key, I hear a popping noise start and the the lights go dim.. That did happen when I took it yesterday to a tech, he said both radios are working fine, only that the superstar 3900G needed the pots cleaned. So..
My question is, I know the standard 13.8v, but what Amperage PS should I have for this radio, and whats the max..?

Re: Superstar 3900G or 148GTL/DX
For a twin final Ranger radio , I'd say about 5 or 6A should normally be enough . Saying that the PSU in the photos that you've uploaded is a US 110V 60hz supply , so I wouldn't plug it in to the UK (240V) mains if I were you .
You can buy a 15-20A switched mode PSUs for next to nothing these days.

Hello John
7A power supply should be sufficient
But 10 A would be better or on car battery
Input Voltage 13.8V DC nominal, 15.9V max, 11.7V
min. (positive or negative ground).
Transmit: AM full mod., 4A.
SSB 25 watts PEP output, 6A
I guess it worked from the start because the power coils L503 L504 got hot at one point

Re: Superstar 3900G or 148GTL/DX
Thanks Claude, so when you say, the power coils got hot at one point, is that normal? Or typical of a radio? On another note, power supplies are not costing Next to Nothing. Man they are Expensive here in the USA (NYC).
A 12 Amp is about $65, a 22 or 30 amp is $80 - $125.. Spent part of yesterday looking online and ebay for a deal. No luck. Smh..

If you don't want to spend the money then there's always this option .

I bought a couple of the PS supplies (1st link is dead for me) for literally a couple of pounds each a few years back (mentioned on a topic about them at the time) and sold them for about £8-£10 each at a car boot sale.
Some people also use computer power supplies as they're pretty cheap and readily available too. Just ensure any mains connectors are safely covered though as usual.
