Truck stop CB SWR meter works for 2m SWR? REALLY?

[mr_fx]

Is this for real? I tried it an got a reading around 1.6 swr, pretty darn close to what the MFJ 269b told me (1.5 ?)

It's a little tricky to read but seems to work

Can it work? Yes, but there's no guarantee of accuracy at all.

(Not that there's much guarantee of accuracy with any meter.)

Given a choice I would believe the MFJ-269 over the truckstop special any day.

I think that goes without saying, the link was interesting, at least I thought so

I've used a few different CB SWR meters that worked fairly well in the 2m range. Are they perfect? No, but they worked well enough to determine if the antenna was safe to TX on.

So no one actually READ THE LINK... did they ??? :angry:

i did, you can turn almost any vswr meter round like that, it means you use the same detector diode for fwd and rev like flipping the slug on a bird.

Exactly. I read the link as well and I also thought it was the same principal as flipping a sampling slug. It avoids any discrepancies between two different strip lines. Try using a CB power meter on 2m sometime and see what happens. It will make a Dosy meter proud.

This technique has been around a very long time. I remember reading about it in a magazine or something way back.

I am not a fan of the truck stop meters to begin with....

I read the link ....found it interesting though....it would work in a pinch if needed,but I would get a hold of a vhf/uhf meter asap to double check with

now thats a funny thought right there
