Good to know. Thanks, JohnAfter having no confidence in my ability to install two Collins filters in my AR5000A+3, but attempting the job anyway, I sent the radio to AOR U.S.A. for a "check-up" and all around calibration.
I found their service to be very professional. He (Taki), was very thorough and neat. I received the radio back in short time and Taki did, in fact, found a solder trace I managed to break.
I would not hesitate to recommend their service and I now have a first rate radio I can never imagine selling!
So stay calm, your baby is in good hands.
