a tall order maam. what are you attempting to accomplish? most of these

If you don't know what equipment you will need, it is very unlikely
that you have the skills required to do the work.

Why would you need years of learning, soldering skills, tons of test
equipment, filing cabinets of schematics, and the ability to see
problems before they happen? Just ask us!

Ok, John, tell me everything you know about the Microdyne RCB2000
telemetry receiver. I worked on it at the factory, and had direct
access to the designers, yet I still needed over $1,000,000 worth of
test equipment and half a file cabinet full of schematics and other data
to make them work. Its no wonder that it cost $80,000 per radio.

WAS that the typical repair bill (ducking for cover!)

Exactly my point though about the fellow asking how to fix stuff easily!

The radios each cost $80,000 new. I worked at the factory where they
were built. All of them were still under warranty so there were no
repair bills or charges for software upgrades. In fact, the first batch
that were shipped did get a field upgrade. We sent two people from
engineering to the customer's site rather than have them ship over a
half million dollars worth of equipment back to us. The upgrade was
required because they had specified the wrong bandwidths for the IF and
video DSP filters. The amount of equipment required to work on a
RCB-2000 was due to the complexity of the design.
