Interesting that some 1225's work better at extreme range than others.
I wonder if there were some parts substitutions by Ten Tec over the
years of production? I have had mine for many years.
I think when I was testing 2 meters I was using a HT, so minimal coaxial
cable was involved. The dummy load was an MFJ coaxial input dry type
dummy load. Or I may have used some BNC dummy loads on short, (very
short) duty cycle. Oh, And I have always used mine with internal
battery, NOT an external power supply. I could see an external supply
causing you to get stray signals into the pickup circuits when above the
rated frequency range.
