Actually Manfred, your government has signed up to them! I'm referring to the
International Radio Regulations, published by the ITU, and signed up to, by all
the participants in a World Radio Conference. Is there not a ban on spark
transmitters? That's in the RR.
Interesting point about iron cores and VFOs. As I recall, the old Command
transmitters were very stable, and they had iron cores in both the VFO and the
PA. But they were magnetically loosely coupled, unlike toroids.
