[Amps] Measuring IMD in a home workshop

[Peter Bertini]

Unfortunately, the K3 transmitter IMD specs are not good enough for
amplifier testing.  A two-tone generator is the easiest part of this
equation.

Not sure what the solution is, a pair of final amplifier decks from a Ten
Tec can be driven with two signal generators (HP 8640 will drive my Omni PA
decks to full power)  along with a combiner... but that will cost around
200 bucks for the assemblies from junker rigs.
