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.

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. |
