Just to advise that two articles - construction projects or kits (unrelated to any of my input) have just appeared in the recent edition of Silicon Chip which coincidentally relate to two topics recently discussed on the forum.
1)
A low power pantry TX design, it uses an MC1496 for linear modulation, it has a tunable output frequency over the MW band and used a ferrite rod coil as an output load inductor and it has a wire antenna. The design looks innovative.
2)
A really great looking RF modulator for vintage TV work, with a proper DC axis maintained for the modulator (which avoids the retrace line issues) and on top of that it has blanking circuitry to remove unwanted signals from the vertical interval. It is probably the best RF modulator project I have seen for vintage TV work so far, it appears to be designed for vintage 625 line monochrome TV's.
I have not attached images of this recent publication, but subscribers in the UK probably have these articles by now.
Their website lists the projects:
