Signal S8 to S9+ in central (upstate) NY

182
Never mind - I figured it out - looks like 10 lines/second does the trick!


This closed out the broadcast at 0307z. Btw, great signal in upstate NY - here's one of the SSTV images I decoded:

(The wavy lines are from interfering relocatable over-the-horizon radar signals - those 2-10 second bursts that sound like digital farts)

183
How many lines per second is your waterfall running at to capture those images?

184
Solid copy here in upstate NY.

0137 Audio & SSTV ID: Outhouse Radio

186
Those are "SSTV" (Slow-Scan Television) images - commonly used by amateur radio operators. If you can pipe your radio's output to your computer audio input, you can use software to decode the signals. I use MMSSTV, a free app for Windows (desktop) - others are available. Here are the images I just decoded from this pirate (my first time attempting to embed images - hope this works):

0110 Booming into the northeast - S9+10 to S9+15 (slight fading)

Jazz music - believed to be a rebroadcast of BSJ-FM in England - definitely *not* direct reception from UK, as this is the loudest pirate signal I've ever encountered (at S9+40!) in upstate New York, U.S.

HF Mystery Signals / Resources to ID VHF/UHF sigital signals?
« on: February 20, 2021, 1452 UTC »
Sorry if this is a bit off-topic. I recognize & respect that this is a forum for ID'ing HF signals. Can anyone point me to a similar forum for assistance in identifying unknown digital signals above 30 MHz not represented at SigIDWiki? Thanks!

P.S. If anyone *does* want to take a crack at it here, I'm hearing an approximately 15 kHz wide intermittent signal on 72.1 MHz that lasts roughly 2-10 seconds and sounds like a pager, but definitely is not POCSAG - waterfall at https://www.lutins.org/temp/701.jpg and audio at https://www.lutins.org/temp/701.m3. Promise I won't pester y'all with above-30 MHz signals again!

0207z  Baby It's Cold Outside (Dean Martin)

I detect a theme...

191
Fairly strong signal in upstate NY with moderate fading.

0145: "All of the Trees of the Field Will Calp" (Sufjan Stevens)
0148: "Don't Worry Baby" (Los Lobos)

Dead air between every song

Thanks for the enlightenment! I too saw evidence of the flight diverting from JFK to Buffalo, but that doesn't make sense, because Buffalo is *way past* JFK if you're flying from Port-au-Prince!

I just got ADS-B software up and running on my RPS1A. I notice route discrepancies between the software it uses (Virtual Radar Server) and other information sources. For example, for Jetblue flight 634 (7 Feb 2021), I observe the following:
 - Virtual Radar Server (Ver. 2.4.4.36598) identifies origin as San Francisco & Destination as Boston
 - FlightRadar iPhone app identifies origin as Port-Au-Prince & Destination as New York (JFK)
 - FlightAware.com identifies origin (Port-Au-Prince, Haiti) & Destination (Syracuse, NY) [these appear to be correct based on the flight track]

So why the discrepancies, and who do I believe? Thanks and happy monitoring!

194
Thanks - sounds like a positive ID! When I use the search bar at the top of this website to search for "6855", nothing comes up (well, except for my post, now). Maybe I don't understand some subtle way it works (or doesn't).

Utility / Military? 6855 kHz USB (voice) starting 2323z 26 Jan 2021
« on: January 27, 2021, 0014 UTC »
I can find no record of 6855 kHz being an active mil freq, but heard what sounds like mil air traffic at 2323z and again at 2357z. Recordings of first message at https://www.lutins.org/temp/6855_1.mp3 and second message at https://www.lutins.org/temp/6855_2.mp3. Transcript (best as I can discern) of first message is as follows (M = male; F = female):

M: [Sevine ?] [Sevine ?] Speedair zero one, Speedair zero one
F: Speedair zero one [flight ?] forward go ahead
M: Charlie three five Charlie three five, Golf two three Golf two three, [chest ?] now zero two zero, zero two zero
F: Charlie three five Charlie three five, Golf two three Golf two three, zero two zero, zero two zero
[beep]
