FM activity on 26.805 MHz right now (1453 UTC)

Several more 26 MHz frequencies now active.  Also some AM voice on 27.045 MHz and 27.095 MHz RC channels. 

Watching 27.255 / CB Channel 23 right now (1500 UTC)

Lots of AM carriers, several different data link data bursts on frequency, with the familiar pair of FSK signals on 27.252 MHz and 27.257 MHz.  Also noting narrower single FSK signals centered on 27258 27.258 MHz or maybe 27257.5 27.257.5 MHz. 

FM voice on 27.255 MHz / CB channel 23 at 1504 UTC!   ;D

And...back to AM voice + FSK data transmissions...

Taking my lunch break, listening to an SDR near D.C. Several stations on. Just listened to a station in Houston,TX working a guy in NY. hearing some SA stations as well on 27.555 USB. Checked the F.M frequencies, but didn't hear much.

26.805 MHz was active a bit ago with some FM stations.  Some sporadic FM activity on channel 23 / 27.255 MHz, but it's mostly AM voice and various data bursts....making for a pretty much frequency at points.

Quick skim of the 11m band using one of my active miniwhips. Not too bad IMO.

Swapped miniwhips, and it seems to be even better. I really need to map their frequency responses sometime, as they vary by bands moderately despite being only about 30' apart.

The taxi cab dispatch radio systems taxi dispatch ladies are starting to fade in now - hearing activity on 27.765 MHz AM, 27.775 MHz AM, 27.785 MHz AM and several other frequencies.

Checking 29.7 MHz to 30.0 MHz and 30-32 MHz real quick...not too much even in 10 meters.

Still a little 11m DX activity here, but it is starting to really drop off.

If I feel like it, I *might* be on 11m tomorrow for awhile if the band opens.

The 11m band has closed, or perhaps more like collapsed, here. Mostly an empty waterfall, and the noise floor is around -124dB on an active miniwhip.

Down to what sounds like a few locals on 27255 AM and 27285 AM, and those catches were with a preamp engaged.

Well, it was good while it lasted. We can hope for another band opening again, one of these days. Disappointed, but it was still awesome to work UK/EU again on 10/11. Brought back a lot of fond memories.
