Midland MXT275 power output

[rharr]

Turns out my jumper cable was crap and my new one yielded better results. Ch1-7 4 watts and 1.01 SWR, ch15-22 14 watts and 1.03 SWR, ch15-22 repeater 14 watts, 1.1 to 1.3 SWR. I had a noticeable alternator whine when receiving. The only receiving I can do right now is the weather channels, no one active on GMRS in my area. I tried a different ground and the change in the whine was reduced but still there. I had the radio's cradle mounted to my center console support bracket. I removed the cradle from the bracket and the whine was barely noticeable. I used self-tapping screws to mount the cradle to the side of my console. My handheld GMRS radios came in today, so I did a radio test between the two radios. On transmit from the 275 there was a noticeable whine, but it was tolerable. Then I went to change something on the antenna mount and overtightened the piece that tightens and holds the antenna cable to the mount and snapped off the stud. So, I get to order a new antenna cable and hope I get the same good(ish) results. I did the same mounting for my CB. Ch1 and 40 2.2 SWR, ch20 1.1, 15-30 1.1 to 1.5 SWR.

Can you clarify jumper wire?

are you call the power wire to the 275 the jumper wire?

I meant jumper cable from the radio to the meter.
