Export Cb radio power plug upgrade

[Xracerx13]

I'd always wondered myself why the extra pin and thought if it had ever been used was for ground because of it being closer to the one used as a ground already.

That's what I thought all these years too. I just tested one from 1978 and the middle pin is not connected. HUH

Do they fit into the radio hole?

According to the picture in the first post they do but I haven't personally tried them.

What actual gain would you get from doing this mod? A few extra watts? An extra volt?

Well, for starters, take my Stryker 955 for example. I set it up with 14.4 volts feeding it. Key it up and it drops to around 13.1 volts +/-.
I made a new power cord using 10g wire and now it feeds enough power that I don't see a drop when keying up.
I had to cut the existing plug and spliced it to the new wire.
Using one of the power plug upgrades in this situation seems to be a no brainer.

What is your radio losing from going from 14.4v to 13.1v ?

He mentioned using a Stryker 955

Literally- 1.3v
But seriously, I understand where your going. But I'm not happy with these results. If I want 14.4 going in, I'd like all of it going in, and that's about it. I'm definitely going to look into the upgrade. It sounds perfect.

Got me questioning that 3rd pin. What is\was it's purpose? A forgotten ground? Can't be to keep from plugging it up backwards cause I have done it, notched plug, offset pins and all. Pop goes the diode.

some power cords came with a red orange and black the orange one was for memory. I'm trying to remember what radio that used the orange wire I think it was a cobra I could be wrong

Some dimensions.

I'm glad y'all posted this up I was looking for a better alternative but I couldn't find nothing and I couldn't think of anything. I've got a cobra 29 with a KLV amp In it I think it's a 203. This should work good with it

It should get you more amperage with less drop in voltage which is great for add ons like that. That's the issue I see when using the rfx units.

The 1.3 drop in DC voltage increases the amp draw of every component that gets voltage inside the chassis.
Increasing amperage causes increased heat in components.
Heat and circuit board components equates to bad “JUJU”.
Lower heat equates to longer lasting components and longer lasting radios.

Also increases the Galaxy Drift!

Uh oh, a little roasting huh!!
I own a couple galaxy radios but I'll take that in good sportsmanship!

My galaxy is a drifter, for sure. Haha... it keeps you on your toes, that's for sure. Actually the only radios I have that don't seem to drift are the radios coming out of Qixiang. I can't tell you how nice it is to turn on a radio and start talking without the dreaded worries about drift! Or having to let it warm up!!

And thanks for the info @Dmans. I'll give that knob a slight turn down, now that I'm getting the power to it.

I remember when I was a teenager I used to upgrade the power wires going to the switch. Sometimes I would upgraded switch itself too it would gain a couple of watts. over the years I have found out if you wanna do a competition radio us a relay
