Dx44hp channel mod

[Amtrak]

With the top cover off on the solder side of the board. With the knobs facing you. On the right side front. There are about 4 diodes. Just remove theses. And you are good

Amtrak… that's what I did, no dice man. I don't have a frequency counter anymore so I don't know what the frequency is doing. It still isn't working tho… I don't have a good shop near me, so a road trip is in the plan

Sorry they are resisters. Not diodes. Pic below.

I just done this to a buddy of mine. On a brand new dx44hp

look to see if yours has the resisters under the PLL. it makes it a lot easier if you guys can post pics of your radios .

That the mod I did … was to remove those resistors ……

Might have to form a solder bridge or remove one, i'm not sure and this is just a guess.
I'd have to look it up but if this model has a "band select knob" or a hi/low band switch it's quite possible you have done the mod correctly and just do not have the radio set to the frequency range you are looking for, you will need a freq. counter or get creative (other radio/sdr) to find out where the radio is at.

I thought this link is what you need, but I now see it says DX55V on the image regardless of what the link says.

Like leapfrog said. You will have to try the different bands and your high low switch.

Wow I hope you get it solved. Another reason why i buy a radio from a shop that does good tech work. The radio gets converted, tuned, and shipped one time. Done.

 

[sonoma]

now more than ;likely it needs to be tuned to get it right on. do you have any thing for test equipment to align the radio and see if you are on the right band.

Most of those radios I think either D, E, or F were the CB band. Hard to tell those days as there isn't much traffic LOL!! But if you have any type of freq counter you could see at least where you are or close to like said. Good luck and like the others have said, hope you find which bands are which.
