Mal,

The harmonic content of a divider's rectangular waveform would be a problem for the wideband detector circuitry in the analyzer. The waveform is typically not an issue for a classic bridge with a receiver for a detector, as the harmonics are ignored.

If you could incorporate a good low pass filter to take out the third harmonic and above, then your idea should work.

Tnx Warren for the prompt reply and also all the others that responded, much
appreciated.
One approach that I had in mind was an outboard bit of hardware like a
divider that fed the ant socket of the mfj 259 b and for instance use the
4 - 10  mhz range, divide by 10 to give 400 - 1000 khz (500 khz band). Has
anyone seen a cct along these lines.
