Hi Michael,
Thanks for your detailed DXing report from Firenze, Italy.
<<< I thought you might be interested in a couple of the
catches that I made last night from our apartment in the centre of
Florence. These were made inside the apartment, which looks over a
courtyard but is surrounded on all 4 sides with other buildings, all
about 4 stories high, in the Florentine style. I have found that DXing
early in the morning from this location is quite possible, RFI is there
but manageable with my combination of Sangean PRD-15 and the great Gary
DeBock 3.5 inch Baby FSL, which I am learning to get the best
performance from (thanks again Gary!). I have placed them both on a
wooden 12 inch diameter 'Lazy Susan' that is big enough to allow space
to adjust the distance between the radio and the antenna while also
allowing an easy 360 degree rotation. This assists in not only reducing
RFI by nulling but also in helping to determine the direction the signal
is coming from, potentially aiding in obtaining an ID. >>>
It's always a challenge to set up DXing in a new environment, especially with a new radio and antenna. You seem to be doing a great job! In December I faced the same kind of challenge trying to transform an ocean side beach lounge area at a large Hawaiian motel into a TP-DXing headquarters every evening (and drawing more than a few stares in the process).
Of course I'm happy that the 3.5 inch FSL is providing you with some useful DXing gain to boost up weak signal reception on your Sangean PRD-15, and thanks for posting some of your DXing results so far. Some of the most (vicariously) enjoyable hobby moments for me have been watching Canadian travelers use my antenna designs for DXing success overseas, such as Walt during his South Pacific cruise, and Colin during his Kona, Hawaii trips. From the beginning the Canadian contribution to the Ultralight radio group has always been enormous. Good luck tracking more exotic DX!
