Re: [IRCA] Computer Model of Bog

Hi Tom,

Do you have any experience with BOG's on the ground? I was wondering how 
they work with a foot of snow on top of them? I've been using #14 THN but it 
costs an arm and a leg at Home Depot, a 500' role costed about 75 bucks last 
time I bought it.
I really like the SS stuff, it's more interesting than TA's to me although 
those too are fun to receive. Yeah I use all boatanchors, have many of them, 
my favorites are the R-390A followed by the SP-600 which is also a really 
nice radio especially to tune, it's like a Cadillac, then a National HRO-60 
which is also very sensitive and selective, it's a real PIA to align though 
with all the coils. I also got a lot of stuff on an HQ-180. The dial on the 
SP-600 is almost perfectly calibrated, I had it restored a while ago and the 
guy did a great job. It's within 1-2 khz on both AM bands.
