From Lech G3KAU and Derek G3GRO,
We hope to have a first foray to the Decca site at Puckeridge in
Hertfordshire ( Loc IO91XS ) tomorrow 11th April to try to tune up the
300ft antenna mast ( top capacitance 3750pf !! ) on both 73 and 136Khz as
a precursor to a more extensive spell of operation at the weekend
14/15/16th of April on 73 and 136Khz.
We hope tomorrow to be QRV by about 1500 UTC transmitting during the "odd"
hours (eg. 1500-1600 UTC) on 136Khz using the callsign G3WSC and G3GRO/P
on 73KHz during the "even" hours with a reasonably accurate 1W ERP on both
bands using the known efficiency figures previously established by Decca
Ltd. It is hoped that this might establish some level of signal comparison
on the two bands and perhaps allow calibration of home made signal strength
meters. We will announce which band we are listening each time and expect
to be on site until about 20-00 UTC at least..
We also hope to have a more extensive spell of operation next weekend with
higher ERP for some limited spells (if the NOV is cleared in time) with ERP
reducing in controlled steps. We also hope to be joined by other operators
who have indicated their interest in taking advantage of the opportunity -
these include Jim G0BMU and Mike G3XDV .We also hope to transmit using
QRSS. We will post proposed schedules on the reflector after the visit
For the record - despite another in the long stream on sour and knocking
messages on the reflector from the direction of Scarborough, - the
operation from the old Decca site is not "sponsored" by Racal Decca - we
merely have the opportunity of access to the mast during the very limited
period before the sites are being dismantled - and have a bit of fun in
the process !
On the Decca site, our mobile telephone number for skeds etc. will be
