HF Mystery Signals / 7335 and 7365kHz CW? 20191116 0216 UTC to ???
« on: November 16, 2019, 1614 UTC »
Maybe CW?  Broadcast on 7335 and 7365 kHz 20191116 0216 UTC until ?????.  Captured from central MD, but also noted on Kiwis across eastern US (didn't check western US).  TDoA suggested SE US, maybe Florida....

Someone on HF chat commented that these are Radio Marti freqs.....

Haven't dug into it but these folks were saying they share their benchmarks, etc.  Other than brute force FFT, wonder what other features would be good for a dedicated SDR rig?  Network I/O comes to mind, but wonder what else.....

There's a company that benchmarks and assembles desktops based on intended software use....

Equipment / Re: Question about radiation.
« on: June 30, 2019, 2326 UTC »
Ditto what Chris said.  Alpha emitters are harmless until you ingest or inhale them.  It's probably radium, but could be promethium, strontium, or (less likely) tritium....(https://www.orau.org/ptp/collection/radioluminescent/radioluminescentinfo.htm).  Promethium, strontium, and tritium are beta emitters which aren't quite as bad when ingested as alpha emitters, but you still want to limit your exposure as much as possible.

I think it would be a very interesting question which isotope the USSR preferred for their instrumentation. 

There are spectrum analyzers that can measure the radioactivity coming off a sample and return a list of the radionuclides present.  If you know any first responder types you might ask them if they have access to one....

Perhaps you could seal the paint back onto the radio with some nail polish or something similar?

Two signal enter.  One signal leave.

HF Mystery Signals / UNID pips ~ 14220kHz 1337 UTC 7 June 2019
« on: June 08, 2019, 1806 UTC »
These came up at multiple frequencies (although I don't recall if they were concurrent) on the morning of 7 June.  Interesting thing is the train on a frequency would cycle up in magnitude and back down again....maybe a directional antenna sweeping around?
