[Amps] Regulations

[peter chadwick]

Roger,

It just so happens that at 1345 UTC this Saturday, I'm giving a presentation at the RSGB National Convention entitled 'Spreading the Sewage' - we didn't think that 'Spreading the S**t' was quite appropriate! I need to make sure that I have at least 2 if not 3 pints of beer available for refreshment during the 45 minutes - although the other year, someone wrote to the RSGB General Manager afterwards to complain about me drinking beer during the presentation and livening it up with a dirty joke!

I have analysed the QST reviews of 123 transmitter/transceivers since 1973 for this, and the frightening thing is the way that while tube rigs in general had negligible 7th, 9th, 11th order IMDs, the solid state rigs do - and then some. Both the FTDX5000 and the FT1000D running in Class A are good.........but, I gather get hot.

As they say in Yorkshire "Tha don't get owt fer nowt".

The results make me glad I still run a tube PA transceiver!
