Some of you who attended the NRC convention heard Neil Kazaross' workshop on
flag antennas. With his guidance I've built one. Using three trees in a
line, aimed NE/SW I put up the Flag in the front yard, with the lower wire 8
feet off the ground, and the upper wire 25 feet. I couldn't get any higher
with the 40 foot ladder, two trees were too narrow to support the ladder at
that height, and the third tree was a mess of branches. If necessary I can
drop the lower wire to ground level after the lawn-mowing seaason, or even
put it under ground with a conduit. The length of the antenna is about 85
feet. Neil provided a 9:1 transformer. There is a 475 ohm resister at the
far bottom corner. There is a 125 foot coax into the house, but there
doesn't seem to be appreciable signal loss. I use a Drake R8B. Other
wires are a south wire (200 feet), an east/west wire (700 feet), and a
northeast wire (about 600-700 feet). Flag results are very positive. Most
of these receptions are not found with the northeast longwire (or
substantially weaker), but present with the Flag. Stations to the
southwest, like WLW, WSB, WHAS, or WTAM, are depressed about 15-30 dB using
the Flag.
Here's what I've noted tonight, times EDT:
2229 774 Koranic reading, faded before I could get a Global Tuners
receiver to try to match it. Egypt likely.
2243 1089 UK excellent
2244 1341 Weak audio, North Ireland likely
2250 1377 France, very good
2251 1521 Audio in heavy WWKB slop, Saudi I suppose
2252 549 Arabic, something here but language may be wishful thinking.
Algeria and Germany have been heard here.
2253 693 BBC very good
2254 738 Spain, fair, enough to ID language
2255 747 Netherlands "I Can hear Music", appropriately
2256 855 Spain // 738
2246 1053 UK I guess, but too weak to ID or to compare with 1089.
2308 1060 CKMX Calgary - matches web audio and song list. Blasting
KYW on all antennas. Fades in and out.
2316 1134 Croatia now off at this late hour, but a het is noted.
2318 1215 Absolute Radio
Yesterday at 1915 I had an interesting signal on 783 kHz, might have been
Mauritania or Syria. I couldn't make it match the Mauritania shortwave
station, and I couldn't find a web audio for Syria that worked. It was not
Barcelona, Portrugal or Germany. I think this was Syria, heard last year in
December.
I'm disappointed to note that more than a few Global Tuners receivers are no
longer listed.
Thanks to Neil and Chris Black for the guidance on putting this together.
Bruce, I'm sorry that this isn't in the form needed for IDXD, but perhaps
you can make this into a feature after the regular reports. People who
attended the convention will be interested in this. More than a few people
have expressed an interest or intion to build one fo these.
