1709.83 mystery: Radio Selva, Argentina? 00:27 UTC 9/24/2018
« on: September 24, 2018, 0048 UTC »
I've been noticing a carrier the last few nights on 1709.83 so I started checking various remotes on the Kiwi network.  My search led me to Argentina where one of the receivers had a station label on 1710 for a "Radio Selva".  Looking closer, the station on the Kiwi remote is right on 1709.83, the same as the carrier I'm seeing here in Michigan on my DKAZ pointed due south.  Such DX from deep South America isn't exactly common here, unless conditions go very auroral, but there are no signs of such conditions elsewhere on the band right now.

Radio Selva's audio stream: https://amselva1710.wixsite.com/envivo

Buenos Aires remote that had the best copy on the station: http://kiwisdr.gastonet.com:8073/

The carrier was pretty strong tonight at local sunset, but fading in and out rapidly.  I was unable to dredge up any audio to confirm it was Selva.

Anyone else seeing or hearing this mystery carrier or know anything about this station?

A very interesting catch, and nice sleuthing via the remote SDR settings. I just gave it a try here, but as it is already 1035z I see it is daytime in Argentina already, so too late. I'll give it a try tonight. The Hudson County NJ TIS is dominant here on 1710, but 1709.83 should be far enough removed that I can at least try to spot the carrier. I am able to mostly null out Hudson with the Crossed Parallel Loop, but then I get one of the other 1710 TIS stations. Which reminds me, I need to finish manually processing the federal TIS station list I got via the FOIA request.

FWIW, We had pretty good propagation from that region last night on 43 meters, the UNID pirate (presumably from Argentina also) was coming in quite well at times, I added a recording to the thread: https://www.hfunderground.com/board/index.php/topic,46222.msg168761.html#msg168761

This is the time of year when the ambc band goes bonkers and weird stuff like this is commonplace, but short lived. You should expect weirdness an hour before and after local sunset.

Yep. It plays Hell on sat. uplinks and downlinks radio and TV station use for their programming, too. It was the annual weekend of disappearing football games. It should be gone in the coming weeks.

It was suggested on another list that this could be a pirate.  I'm hoping Daniel Wyllyans sees this and can provide some more insight. The station also have a FB page here:  https://www.facebook.com/amselva1710/

The carrier is starting to fade in again right now as I type this.
