Just as the subject title says, I have an HR-2510 with the chipswitch installed. It has been in a temperature controlled environment meaning no hot garage, car or attic. It looks NEW and works perfectly. No limiters removed or other mods other than the chipswitch. Comes with the box, manual, bracket, power cord, and hardware still sealed in the plastic. The only things that were ever removed from the plastic was the power cord and mic to use it years ago, and then recently again to test it both into a dummy load and on the air. Asking $300.00 shipped. Local pick up or postal MO please. If shipping, will be double boxed.
