Tuned in at 2225utc, weak signal, detect carrier in ssb mode but hear no audio under the noise so far,

I have been using online receivers because of strong data hash interference in my neighborhood that I believe is caused by Uverse squeezing up to 100mb/sec through ordinary pairs of wires. I don't have Uverse but neighbors do. williamhassig@yahoo.com

I have a faint broadcast, but it sounds like a harmonic, spur, etc. of a typical Cuban Spanish-language shortwave broadcaster, which is a distinct possibility here given my location and currently using just a cheap RTL-SDR and a 9' outdoor vertical while in the den away from my usual receivers.

....


Just skimmed the tropical bands. It is an image of Radio Rebelde on 5025 for me. Not sure it is the same for ya'll, but I have seen 5025 popup on other frequencies before, even on decent receivers. However there is my proximity to Cuba with 5025 being an over S9+60 signal here at times. o.0

6944 quite strong carrier on K3fef SDR.
Very faint music for a few seconds, now unmodulated.

There is a carrier on ~6945.25 via the WCRC WebSDR in Texas:

http://74.118.150.5:8901/

Sounds like some type of UTE with intermittent modulation. I suspect whatever is being modulated might occasionally sound rhythmic, especially at it nears or falls into the noise floor. That has happened to me with UTEs before.

My earlier local 6945 logging is due probably to overload, which is a rather common issue with the RTL-SDR design.

The only thing I had here was the carrier from the Link-11 transmitter, was was on much of the day, and is now (1253 UTC) active with traffic.
