I, too, have noticed the difference between Orbitron and the ACTUAL frequency. I saw that the SO-50 page had mentioned this a while ago...so I've always just hunted around for it. I use an Eggbeater...so I'm not too concerned with this matter. However, I can see that it would be a SERIOUS issue for someone that is using a more elborate antenna setup.

Any theories as to WHY this may have happened? Mine is simplistic...I had a Ten-Tec Argonaut 505, and it drifted somewhat due to the temps coming from start-up...then the amplifier finals, etc. So, it was pretty drifty.

Well...it's a theory anyway.
