Hi, here is a bare bones SSB modulator/demodulator
Tested by VK3YE at his page http://home.alphalink.com.au/~parkerp/projects/projssbphasing.htm (4th video down the page)
I tried to build it but it does not work. Even if I fed a high signal at the input of the transformer I get very very little increase in the carrier. none of the three port seems to respond to any settings.
I have used the same AF transformer with the 2K CT connected as shown. I figured out the 2K winding with a multimeter, which showed a DC resistance of 120 ohms if I remember well.
The DC resistance at the 10K end was around 600 ohms.
I used 1n5712 diodes instead
For the output transformer I used 4 turns on the diode side and about 30t or so for the output side, wound onto a T50-2
Any help please what to do?
