Title: Signal on 6947.45 or so
Post by: Ron Hunsicker on April 19, 2016, 2356 UTC

For a week or so, I've seen a signal on 6947.45 or so which looks like AM on the waterfall of my Elad FDM-S2.  There is a strong central spike that is about 50 dB above the noise and what appear to be very small sidebands.

What is it?


Thanks,


Ron

I was wondering the same thing. A strong carrier, but no audio. It seems stronger in the afternoon here and is intermittent.

Is it not the UTE that likes to hang out there, usually in slow speed FSK?

I've observed it sending KG84 encrypted FSK (RTTY) in the past.

Yup that UTE has been there on and off for the last several years, destroying what used to be a good AM frequency of 6950KHz.
