Does anyone have information on a dx44 hp band board? I have one I picked up at a thrift store. Looks like someone tried to channel mod it and wasn’t successful.
I got the chance to power the DX44 hp up and do some quick checks. Turns out the channel mod was fine and everything seems to work correctly except when you release the mic key it transmits in both depressed and not depressed. It would stop transmitting in between the two. Strange right. So I opened the mike head and removed the green wire from the switch and all works well.the green wire is the only one on the released side of the mike switch. I have a 2547 so I tried both mics and the same result. I figure something on the mic board is bad inturnally but for a$40 radio I figured I’d just Wes it with the green wire disconnected.

Antenna length on my mobile. So I’ve had 3 different radios in my truck. 2006 f250 super duty. 29ltd NW, 29 ltd clasic, and now a galaxy DX44HP. My steel whip is somewhere around 89”. Which I know is way to short. But show 1.2 SWR on all 3 radios. And I have a a bench SWR meter that shows the same results. Which I find odd and disturbing. Note the frequency is 27.205. The longer I make the whip the higher the SWR. At 102” it’s up around 2.5. Which totally blows any of my experience i have with mobile radio antennas. I have the antenna mounted to a post just higher than the cab. I’ve swapped the jump through several to different ones. Even tried lug and so239. Connections at the antenna. Seems to transmit well and receives well. Any ideas how this could be possible?
Turns out I was missing the ground to the cab. Problem solved. Now have 102” exact and 1.2 SWR 26.005 megahertz through 28.005 megahertz. Pictures posted on my profile.
