I am the type that likes to use test equipment as laid
down by the alignment instructions in the book. My
workmate always achieved better results than me.
He would say to me "Can't you hear that the tone
just doesn't sound right?" I couldn't hear what
he was on about. So we used to have a good laugh
about my bench having signal generators to cover
455KHz, 10.7 Mhz and the desired UHF channel.
Oscilloscope, noise and distortion meter,
frequency meter and dummy load/power meter,
modulation meter. If there was a spectrum analyser
available I would have a play with that too.
I just liked playing with the gear. My work mate got
far more two-way radios fixed and out the door than
I ever did. He was good. He had the ear for it and
magic hands.
Hi John,
Some people just seem to have an almost supernatural ability to do
this with virtually no technical knowledge. I can't begin to tell you
the extraordinary feats I've seen done IRO radio mods and tweaks by
people who shouldn't, by any reasonable measure, have had an earthly
clue about what they were doing!
