Does anyone have a set of plans for a modulated RF generator suitable

Drew Diamond, VK3XU, has published a few things in this line - in his
books "Radio Projects for Amateurs" now up to Vol 3. Available from TTS
Systems (one that I know of..) - excellent books, can recommend them to
anyone interested in home brewing.

If you want something with calibrated output, there has NEVER been a
better time to get a good used one - so much high quality test gear is
being sold off, as most telcos etc no longer maintain expensive gear
and trained staff to run it - cheaper to replace the equipment with a
new one.
