About S9 +5 peaks in NE Wisconsin, 23:44

2
Anyone get any recordings of the voice/ID for this one?

3
23:37: 10-15 over S9 into NE Wisconsin on a KiwiSDR. Great signal!

Equipment / Re: Sky loop...height vs diameter

Follow up... I ended up putting up a 40m horizontal loop for now at 34 feet (10m) height, corner fed, 3 sides, with a 4:1 balun/1:1 balun combo. (Palomar Engineers)

I'll start with this, get some noise/RFI tackled, and eventually either add another antenna and a switch, or expand this to a larger loop.

10 years later....what's the thought on big loops, but low height?

I have a new KiwiSDR2. And I could put up a long loop this year, but it may only be 10-15 ft high for now..... My other likely option is an OCF 80m dipole at guessing 35-40 ft as an inverted V.
(The thought being probably next year I could get a higher 500 ft or 1100 ft loop in the air for transmitting as well, and use that.)

'73 Magazine ran an in depth article in the late 90's called , "What's The Scoop on The Lazy Loop?" on full wavelength horizontal NVIS loops. As Chris said, the bottom frequency seems to be the key with the things. According to the author, if you could get up to about 1/8 of a wavelength for the bottom frequency the thing was an exceptional performer for receiving and transmitting up to about 15 meters.

I found this article (here: https://ia904702.us.archive.org/35/items/73-magazine-1998-09/09_September_1998.pdf ) and read one from 1983: https://ia600602.us.archive.org/30/items/73-magazine-1983-05/05_May_1983.pdf

Which seems to make me think it's worth trying a 10 ft high big loop with a balun, but understanding it will be better when higher....
Any more insight on this since then?

I guess my question is: Horizontalish wire in the air 35-40 ft, or 10-15 ft high long (300-1000 ft) loop for 0-30 mhz receive?

Note this change for the KiwiSDR2:

“….Every KiwiSDR 2 has the proxy service enabled by default. So you can connect using the serial number, e.g. 21xxx.kiwisdr.com

If you don’t want your KiwiSDR2 accessible from the internet, you will need to disable this.

Sure, but they would need to know/try every serial number....and easy enough to add a PW for users outside your network.

Got my KiwiSDR2 the other day, thrilled to have my own!

First round of KiwisDR2s are all gone. Got mine right away!  :D

Hopefully they ship from NZ in February as promised.
