this in my opinion - http://sec.noaa.gov/pmap/ - because for those of us that live under/near the Aurora signal-sucker, propagation on all bands is at time limited by even moderate A and K levels an
Most of this week the aurora has made some beautiful night time viewing for us in the Northern and midwest states but its has caused strange conditions on the short wave bands. Barry W9UCW reports a

Hello from Gary NL7Y in Fairbanks, AK. Here's my tentative thoughts regarding the Yaesu key-click issue. I'm on my second Mark-V, the first was a used 2001 production 200W version, and the current is
Hello Jim K9YC from Gary NL7Y...I've built dozens of wire antennas out of #12/14 THHN...I decrease the typical textbook dimensions about 3% when using coated wire...for example, I use 226 for verts,
You could also try center feeding the dipole with one leg horizontal over your property, maybe with a drooping end, and drop the other vertically to near the ground with a horizontal run to finish of
Here's some info of interest regarding antennas and trees from K9LA that may have already been discussed: http://mysite.verizon.net/k9la/sitebuildercontent/sitebuilderfiles/ low-band-antennas-and-tre

One not too secret secret is to place the noise canceler inline with the receiver output/input jacks (if has them), instead of inline with the antenna in/out fitting on the radio...connect the receiv
I have two selectable low-gain noise sense antennas feeding my MFJ-1026. Each are 10M dipoles, but could be any length, one vertical/one horizontal, to match the polarization of whatever noise sourc
Had a similar thing. Was a sodium light with a bad bulb (they're orange in color:http://en.wikipedia.org/wiki/Sodium_vapor_lamp) on a nearby commercial business 200' away. The igniter unit would fire
Sounds like typical daily propagation (ground-wave???) we sometimes experience with motivated locals in KL7 during mid-day. Gary NL7Y _______________________________________________ Topband mailing l
Around Halloween, and with the arrival of perpetual below freezing temps in northern KL7, we tree-hangers often see changes in our vertical antenna resonance. For example, my 160M Inv-L, vertically u
Earlier in this thread: Thanks for the reply Rich. I agree with the changing ground conductivity on a seasonal basis, such as ground conductivity is in Interior Alaska = poor at best I believe. But t
Slingshots are for kids. Professional shooters use these: http:// www.eham.net/reviews/detail/6687. I've used both and for tall trees the big rig works. 73, Gary NL7Y ________________________________
The insulator loop will work. Anything that amounts to a strain relief will work. What I do in a very similar situation is tie some nylon cord (in a series of about 10 tight half hitches) around my i
I would second Paul's observation, and would add by asking if anyone else here has offered similar broad subject information to the amateur community in a similarly accessible format? His efforts may
Pretty quiet up here in KL7 last eveonly sigs were between the Auroral zones, not across. Mainly 40M. Will try 160 test again tonight. Poor propagation culprit: http://helios.swpc.noaa.gov/ovation/#

Well, my Wellbrook might work as well yours, as I too have worked CE/K7CA with mine on 160 from the Black Hole of KL7. More than once as well. For me the magic isn't directional gain, it's the improv
