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.gm4slv.org.uk/tx.htm 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! 73, Dave G3WCB IO91RM nr Windor SE England -----Original Message----- From: owner-rsgb_lf_group@blacksheep.org [mailto:owner-rsgb_lf_group@blacksheep.org]On Behalf Of Gary - G4WGT Sent: 24 July 2008 20:37 To: rsgb_lf_group@blacksheep.org Subject: LF: RE: 600m Info 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.

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?
