Variable power switch

[The Howler]

Looking at one of these Variable power switches for a Cobra 148 GTL Malaysia. Anyone have any experience with one of these, or is there a better choice?
Thanks, Greg.

There is always a better choice. I would do it under dynamike knob which is useless anyway.

I considered that option, but prefer to keep the stock features and go with dedicated Switch.
Thanks

...and drill precious 148? That's barbarity.
Solution I suggested is reversible and leave no damage marks.

Those are pretty good points. Do you have a wiring diagram?Would this leave the Dynamike at the max setting?

 

[sp5it]

I could draw it for you, but i need board nr you have, to find proper schematic.
Yes, dynamike on max setting or any setting you need. For stock mic does not matter, for preamplified one you can adjust output level inside mic.

Sure do appreciate your help!

Maybe you could get a dual knob pot and keep both functions?

We use the SWR Cal knob. Resistance value is right. Need to finally post the full description one of these days. A couple of fixed resistors connected to the SWR meter circuit can take the functional place of the control, so the SWR meter still works.

Gonna guess that they're charging a premium price to sell you a 5k pot.

well they are charging for 1 pot 3 wires and 3 dabs of solder LOL

by the way nomadradio i'll be waiting for you to post that info on the resistors i'm using the swr for variable power too. thanks and with the resistor does it work for a set dead key like 4 or it doesn't matter

Price didn't seem too bad, comes with wiring diagram.

Best option IMO is to use an existing switch like the CB/PA switch for a dual level power control.
both levels are adjustable from inside the radio, and really, how many different power levels do you actually use?
in my experience, people tend to use two different power levels most often.

and sp5it, isn't it Barbarism? LOL
