Hello.
Have you ever seen 2510 working only between 26.000 and 27,999MHz? How to open it to 10m?
Seem to be untouched.
@Rogerbird1 ?

It depends on the radio's version; several different HR2510 versions were produced. YMMV@cdoc radio mentioned work up to 27.999 only.

I came across a clean Kenwood TS-430S once that was locked to 11 meters. I passed on it, but remembered thinking... why? As you have seen over the years, people do some weird mods. Hope you get yours figured out, they are pretty great rigs.Over the years I had on my bench more than 200 of HR2510, HR2600, HR2830, Lincoln's and similar for repairs or tune.
None of them were locked just to CB.
