Early unmodified FT-1000MK V's are well known for producing nasty key clicks, largely due to a fall-time of about 1 ms. W8JI has an article on his website about the problem and the fix. Since these w

The master oscillator is actually on the A-10 board on the underside of the radio. Even from the factory, most Orion's were calibrated about 20 Hz off frequency since they were probably adjusted with

An interesting thing I found is that as my Orion II got older, the master oscillator got more stable. I used to have to do the recalibration process every few month to keep it within my target of +-

Ray: The biggest RFI problem I found with the Orion II was RF getting back in via the headphone jack. There is a small mod board that the factory can supply if that's the source of your problem. I wo

That's what fixed the headphone problem initially for me, but the factory built a little plug-in board with chokes and caps that installs inside the radio. That fixed it for good! Of course, the whol

Since I run remote, I haven't looked at the display, but I do agree that the distortion problem is gone in 566v3.029. Also, the NR seems to have a better range of control than with earlier versions.

It still sounds to me based on your original comments that the noise you are hearing is actually originating in the PA of the other radio, not as a result of lack of selectivity or front-end overload
