Default Re: David Robinson's System A modulator

Bill, thanks for reopening it.


I have built a second version of this modulator and have made some changes to it.
I have changed the test card to one in the style of a PM5544, I have moved the audio gain control to the front panel and have fitted toggle switches for selecting test card and test tone.
If anyone would like to build one all the files that are required can be downloaded here.
