Using HW 100 or 101 for AM

[Stu Lyon]

There was an article in Electric Radio a couple of years ago on AM operation
of a SB-401. It described two methods: one was to somehow unbalance the
balanced modulator and running the AM  through the various mixers and IF
strip. The other was to screen modulate the 6146s with a copy of the DX-40
(etc) modulator. Both looked like real butcher jobs.

A bigger problem on the HW-101 is coming up with an AM detector. You could
replace the CW filter with a wider bandwidth AM filter.

I have a HX-1681 and have occasionally considered screen modulating it with
an external modulator married into the power cable from the HP-23.

Is it feasible to use a HW-100 or 101 for AM transmitting? Would it require
more than a audio modulator? Has anyone done it?

Tnx,
