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 .... !
