VXO is the only common stage. On TX, the VXO feeds an NE602 balanced modulator. I used an LM386 as the mic amp (that's what I had available). For the microphone I use an old SONY walkman mic. On RX, I have a bandpass filter followed by an NE602 functioning as an RF amp. Balanced output to another NE602, this one the product detector. Using a simulator, you may need to get as close to perfection as possible so detectors can be simulated to determine distortion characteristics (for example). The last thing you need is a modulator that creates so much distortion that the end result is impossible to determine. Sep 19, 2015 · Time to build something again.

You have to shell a considerable wad of bucks to get one. Most western designs are designed around them, but I personally eschew the use of NE602/612 for its low IMD range leading to non-serious design contemplations. Lately I saw some designs using MC3362, TBA120, LA1185 and TA7358 as mixers.
