Hi Graham,

   its a good thing that they did the ice-road truckers series before the 
economic slowdown, traffic this year has been very light with a drivers not 
even making their expenses to come up here.  Anyway, I'm in avionics for an 
operator up here.  My apprentice is leaving, over pay issues, to work for one 
of our competitors, Buffalo Airways.  You might see him on TV in a year or 
two as the people who did the Ice Road Truckers series are doing another one 
on Buffalo Air. The attraction there is that they're just now making the 
transition over to turbine aircraft with some Lockheed Electras, prior to 
that their fleet was made up of DC3's DC4s DC6s and a couple of C46s.  
Apparently parts these vintage machines are too hard to find so they've 
updated the fleet with the Electras.

   Thanks for the antenna recommendations.  While it isn't practical to put a 
top hat on the tower as the power lines pass withing 7 metres or so, I could 
use the off-centre fed 80 metre dipole feedline as a vertical antenna for 
receiving.  I've been told that the landfill they used to make the parking 
lot, that the house is in, has a foundation of old car bodies.  So I should 
have a good ground, and I know that I have one of the quietest places in town 
with respect to RF noise.

    If, or when, we get licenced to transmit on the band then I'll be looking 
for some options.  I did find a web site with a cursory description of a home 
made Isoltron loop type antenna for transmitting on the 60 metre band, if it 
worked it may fit my available space.

    Its time to call it a night.  Thanks again,

          Ron
