Fine Ron,

Well quite a lot of uk stations are running T or some form of top loaded vertical , with 35 feet vertical section, mine is in the form of a inverted L with 35 ft vertical, 40 turn/3inch top loading coil and 2 x 40 foot parallel ,capacity section, so your towers look to be fine ? what is the ground earth like , assume the lakes are fresh water ?

500 seems to be a funny frequency as theses small arrays appear to radiate quite well and distance/power looks good , 50 watts of mfsk prints well at 5/600 miles range

A short 'long' wire may not work as well as you might think ..unless you can get the height , due mostly to ground capacity .. but if you can get 1000 mtrs out at fence height .. now that may do the trick (for rx)


Andy's beacon is running 100 watts and looks to be reaching K4 land 4000 miles , you look to be 3600 miles so should be in range ? you could try loading up a T ,atu at the base and take a look on 503.7 , using the ral/plx software for the 5 meg project ? other beacons are about but are not 'timed' so need spec-lab, wsper or similar ..

73 , G ..


Nb ... There has been a tv series showing the ice road truck's taking goods up the frozen lakes quite amazing to watch .... !

Hi Graham,

   my actual location is at postal code X1A 2H5

   I'm in the company crew house at the float base.  In the Google map for
the postal code, at the highest available satellite magnification, you should see floatplanes along the parking lot and then in a cove on the upper side of the parking lot is a yellow Cessna floatplane. The house just to the left of
the floatplane is where I live.  Unfortunately, as the house is in the
floatbase parking lot, there isn't any antenna space around it.  What I do
have is two 15 metre towers spaced about 48 metres apart that I use for my HF antenna (it used to have a company commercial HF antenna before). Any LF/MF
antenna must be compact and mountable either to the house or one of the
towers.  Power lines are between the house and cove, which may be a noise
source.

     Ron

the  location looks a bit tricky ......a low long wire may be good .. but
can you  get one out , looks to have roads all round ?

Ron

I would recommend a loop antenna, there are various designs around such as
Jim M0BMU's design, http://www.wireless.org.uk/BPloops2.pdf Even though
you're in the middle of nowhere there, you should stand a chance of getting
some of the US 500kHz stations ( www.500kc.com ) going under the calls
WD2XSH and WE2XGR with numerical suffixes identifying the individual
stations. We in the UK have 10W ERP but it won't be easy to get right over to you... Maybe you could contact some of the US stations in the North and
do some test with them first?

Good luck!
Dave G3YXM.
