I have moved beacon "IO" in western Maryland to 185299.2 Hz.  It looks like 
this may be a clearer spot.   If anyone has been listening for something on 
that freq, let me know and I'll QSY again.  Fortunately my signal seems to 
be so weak it's not going to bother anyone.

This is my first attempt at setting up a beacon on 1750M - and I'm learning 
as I go.  I really need to turn my loading coil into a variometer - the 
finest tap I left when I wound the coil was 2 turns and I get wild 
variations on my rf ampmeter from just 2 turns difference.  Right now the 
antenna and loading coil is a mess of alligator clips and strewn across the 
deck - cleaning things up may help too.

My meter shows about 22ma of RF current - I believe this is way short of 
what would be expected.  Properly tuning the antenna when I finish the 
variometer mod should help a lot.

For a while I had the bottom of my loading coil hooked to ground, and tapped 
the feed point several turns up.  Since that created two points to tune,  I 
removed the connection to ground and now I just have the loading coil in 
series between the feed and antenna.  I've read various articles about 
antennas - and both methods seem OK.  Does anyone have any suggestions in 
this matter?  If I left the ground connection on the coil, how do I tune the 
feed separately from the antenna?

Give a listen on 185299.2 - any reception reports are welcome!  I'm still 
not 100% sure of my frequency, so feel free to "look around" a bit too.

Thanks!

Craig
