Steve, LF,

I agree with Gary about the M0BMU LF Tuning meter. It works fine without
modification although you will probably have to re-calibrate the Antenna
Current part - mine reads low on 500 kHz.

Getting going on 600m is pretty easy compared with 2200m - the major hurdle
in the UK seem to be the need to apply for a Notice of Variation to one's UK
license.

Here are some useful 500 Khz resources:-

http://www.wireless.org.uk/geton501.htm

Mike G3XDV has produced a book that contains 600m info - check out the RSGB
bookshop.

And there is plenty of expertise to be found on this reflector as well!

Steve, LF,

Re: "Scopematch"

I built the "LF Tuning Meter" from Jim M0BMU for 136 KHz & I now use it for
500 KHz & it works just as well.

Quoting from the article :-

"This LF tuning meter was conceived to perform the same function,
but to be a simple, self-contained unit requiring no additional power
supply."

Subject: LF: 600m Info

Are there any web sites devoted to 600m circuits etc? I am aware of the U.S.
group one as well as G3YMC's page and N4ICK's tx design, but perhaps there
are others as well?

Several of the 2200m experimental licencees have just been asked to submit
formal proposals for 600m experimental permits here in Canada so things are
starting to look positive but I have no idea of the timeline. Just in case,
I thought I had better get the soldering iron warmed-up once again, not that
it has ever really cooled-off.

Also...does anyone know how well the M0MBU scope match circuit (that works
so wonderfully-well on 2200m) performs on 600m without any modification?
