General Radio Discussion / The Codebreaker - PBS

This seemed the most logical place to post this for the most folks to see, but feel free to move it if I'm wrong.
I considered Numbers Stations... Sorry for posting it late but it will be repeated in
most areas and should be available on the PBS website. BTW: I thought it was a
very good program.

Tonight PBS American Experience will show "The Codebreaker" at 2000 CST on Ch8 WNPT and at 2100 CST on Ch22 WCTE (and repeated at other times).

"Based on the book The Woman Who Smashed Codes: A True Story of Love, Spies, and the Unlikely Heroine Who Outwitted America's Enemies, The Codebreaker reveals the fascinating story of Elizebeth Smith Friedman, the groundbreaking cryptanalyst whose painstaking work to decode thousands of messages for the US government would send infamous gangsters to prison in the 1920s and bring down a massive, near-invisible Nazi spy ring in WWII.

Her remarkable contributions to the science of cryptology would come to light decades after her death,
when secret government files were unsealed. Together with her husband, the legendary cryptographer
William Friedman, Elizebeth helped develop the codebreaking methods that laid the foundation for the
National Security Agency (NSA)."

Chris, very good images. There's a lot to be said for being able to automatically
follow the Doppler shift - personally, I use the manual "click the mouse" method! :)

Been booming in here at S9 +20 since ~1300 or so...

0001.45 - SDR recording: at end of Lincolnsire Poacher OM with what sounds to be
                "What in the world are you doing on a Friday night?" followed by
                a little more talking that I can't make out, even after multiple replays.

2356 - Multiple IDs by YL
0002 - More IDs by OM over mx(?) :)

Mostly good sig ~58 with some QSB

Rizla, Check out "Radioactivity" CD by Kraftwerk - a very nice opening. :)

6943.500 kHz
0020 - 170 hz shift, 45 baud RTTY with repeating, and unusual,
             No ID

0038 - Now something that looks like MFSK. Maybe op is playing
            with different digital modes??? The LINK-11 starting up
            doesn't help. I'll have to play back my recording later and
            see if I can decode anything else...

~0135 started hearing "In A Gada Divida" - Iron Butterfly signal was up and down
0155 - "Autobahn" - Kraftwerk and now a very solid S9+ sig
Thanks for the great mx selections!

Great photos guys, I'm envious! I got some OK views
but never a good chance at photos again; guess I
shoulda made another O dark-thirty expedition to the lake...

Uh, oh, someones playing "In A Gada Divida" on 6925
here come the flashbacks :)......................................

Gotta to apologize - I got up at 0300 today (Saturday), made a short drive over to the
Corps of Engineers Boat Launch area at Old Hickory Lake
and got some great views of Neowise. It was a very easy binocular object and
barely, to these old eyes, "nekked" eye object.

We had a weak cold front come through yesterday and the temp and dewpoint
dropped. The temp was 68 and dewpoint was 62 with a light breeze from the
lake - very comfortable for here in mid-July.

Tried for some photos but discovered a little shake in the tripod with the 300 mm
lens hanging on it so all the pics were no good.

Starting Monday, 13jul20, Neowise will become an early evening object.
spaceweather.com has some "how to find" sky maps.

Amen! I ain't holding my breath - or even unpacking the telescope :)

Hope you hung in there because 6 is just now closing out for me (EM66)
(on SSB, FT8 is still busy) after a very good opening to New England
FN3x & FN4x grid squares. Nodzing on 144 or 432 :(

"Maybe tomorrow"!

I have a public Kiwi at: http://midtn.dynu.net:8073
It is in a noisy environment with a sub-optimal antenna, which puts it low on Chris' survey list.
However, it is there for anyone to use. After the Ken Burns series "Country Music" ran on PBS last fall,
I've seen an increase in connections, world-wide, to WSM 650 AM, which I can hear on a wet string from here. :)

In an effort to improve the antenna situation, yesterday I set up a MLA-30 from e-bay. I mounted it
on a 10' piece of 1" PVC water pipe, with 1/2" cross arms and found the perfect temporary mount - the
1" PVC fits nicely into the umbrella hole in the middle of the deck table! That also puts it ~the same height
above ground as the present "kinda 20 meter", "kinda dipole" that the Kiwi has been using.

First impressions, totally subjective comparisons from listening around, is: above ~10 mHz, the dipole is better;
below ~5 mHz, the MLA-30 is *mostly* better. Bottom line - the MLA-30 is going into the shed until such time as I
need / want an antenna dedicated to <10 mHz, or I run into someone who has NO antenna and needs something,
anything. In my *never humble* opinion, save your $$$  :(!

PS - I have read reviews that said the Bias-T system is noisy and I found that it was not bad - except -  ~10 kHz - 170 kHz
where it generates noise that is ~30 db above the noise floor. I also tried powering it from the Bias-T connection on my RSPDuo
and saw the same result so I think the noise is NOT due to the switching wall-wart I initially powered it with. At night,
I can copy WWVB @ 60 kHz using the dipole; NO WAY using the MLA-30.  --- Just my >2 cents worth!

Monitored during flyover today:
360.700 Coordination with BNA tower
289.800 Aerial refueling
237.800 Some a/c to a/c chatter
284.250 Primary pilot to pilot chatter and commands

Great show and I even got a few reasonable photos!
