GME Electrophone TX4400

Hi all, just a quick one. Do these UHF's have an adjustable TX power setting (such as those found on handheld's)? Or does it just operate on the rated wattage (5w in this case, I think)? My TX4400 is a slightly older version (got it from a mate) but is still in excellent condition and operating order.

Cheers.

I have the 4400, there is no adjustment for power output when transmitting.

There actually is a TX power adjustment on a GME TX4400. But you have to open it up. And the gains are marginal.

When I open it, what do I look for? If I can adjust it, how do I do it?

Thanks.

What he is talkingabout should be left to the experts as it increases the output past legal aspects. You may gain an extra 1 - 2 watts, but put the set at risk I believe.

Thanks Shaver. I do have access to a VSWR/power meter and it shows that the radio is producing about 3W ATM. This may be due to the age of the set? I can't calibrate the VSWR meter to get a proper SWR reading because it seems that I'm not getting enough power to get the needle to the calibration point, if that makes sense. This is why I thought the radio might be set on a low or medium power setting. My mate is an amateur radio enthusiast and he's been helping me with most of the setting up, well up to this point anyway.

Cheers.
