To All...

My The low frequency experimenter's handbook was published in 1995, feel it is very much outdated, are you talking about this book or is it a later book?

To All from PA0SE

RSGB's magazine RadCom of January 2003 features the first part of an article by David Bowman, G0MRF, with title "A Class-D Transmitter for 136kHz".

As far as I can judge it is the same design as found in The low frequency experimenter's handbook by Peter, G3LDO, which has a picture of the amplifier on its cover.




Thanks for the publicity Dick.

I do have both parts of the 136k TX article as .pdf files.  Should anyone who is not a member of the RSGB want a copy of the article, please send an e-mail direct to me and I will forward.  (apx 300k per file)
You may need Acrobat Reader version 5 or above to open them.

73  + Merry Christmas to all.
