Thank you Andy.
 
I had wondered why my enthusiasm to read RadCom had been somewhat reduced recently. Then after Andy's mail I looked through the current edition and found not a single constructional article.  Thank you for the wake up call.
There was a time when, certainly when Mike G3XDV was editor, when technical articles were backed up and you had to wait months for something to appear. I wonder if that is still the case but that they are just not being published?
Re 500kHz.  Sourcing parts for a project is a big problem for an individual and although this is a personal opinion. I think anyone wishing to give 500kHz a shove towards popularity needs to do 2 things. 
1) Design a transmitter that represents a moderately 21st engineering but without including so many extras you need a mortgage or a several weeks and a binocular microscope to build it.
2) Having done that, be prepared to invest in some PCBs and key components for the design. Or be prepared to supply complete kits.
 
This process has worked well for the microwave operator with G4DDK G3WDG and Andy all producing reliable designs giving access to bands where no comercial equipment exists.
Of course, something working against this process at present is that 500kHz is only with us at the 100mW level and the NOV is limited to March 2008.
Maybe, if that sitaution changes.....1W and permanent access would be nice....then the designs and kits will appear.
Standalone CW TX ?   Transmit converter from HF?   Something software definable?
Maybe a simple DDS that could generate CW or PSK or FSK modulation.
 
Plenty of ideas on the wish list, but only if the band carries on beyond 03/08.
 
So many things to do, so little time.

How about writing a few letters to the editor about the appalling
tabloid route the Radcomic is taking?

Giles (editor)  himself is a bit concerned about the route the comic
is moving, but I get the feeling he is being pushed by the RSGB Mafia,
sorry the Board.   The two job titles that used to run the magazine
were "Editor" and "Technical Editor"    now   they are "Managing
Editor" and  "Features Editor" .  That sez it all!
