I tuned back in to 107.7 FM at 1210 local (1610 UTC) 27 August 2019...and only heard a carrier.  Unmodulated as far as I can tell...107.7 MHz is quieted. I checked 107.9 MHz and itís also quieted, with bits and pieces of audio from a distant station breaking in at points.

Presuming itís still Virginia House Radio on the air on 107.7 FM - itís just a carrier / dead air.

10/11 meters / 11 meters is active 2200 UTC 26 August 2019

Some late afternoon/early evening activity on the ΣSDR - CT/MA Border (COMMSIGMA KiwiSDR).

Several stations talking on channel 6 - 27.025 MHz AM and several other in-band channels, generally the usual AM high power CB channels (6, 11, etc.).  Locals talking on channel 31 / 27.315 MHz AM and some sporadic activity on 38 LSB 27.385 MHz LSB.   The usual local FSK bursts are also coming through nicely on 27.255 MHz...no sign of distant data bursts or telemetry on 27255 or 26.995/27.045/27.095/27.145/27.195. 

Edit:  weak FSK noted on the waterfall on 27.255 MHz - channel 23 at 2212 UTC.

Channel 20 27.205 MHz is active with AM DX traffic as I type this (2213 UTC).  Lots of fading though.

I heard a few bits and pieces of the Baltimore, MD station KEC83 on 162.400 MHz this morning about 0650 local time (otherwise, the band was meh, especially compared to the catches of the other day).   Of course, I didn't have the camera going this time because the conditions were nothing special...well, until KEC83 came in out of the blue. 

162.550 was the usual fight between KHB36 and KHB37, but neither of them were as strong as they have been in days/weeks past.  162.450 was the usual story as well, with KZZ28 coming in nicely and another station noticeable underneath it. 

On an offhand note, I have my Motorola MTS2000 VHF handheld with me today and put it on 162.450 while sitting at a red light and could copy KZZ28 just fine with the factory Motorola VHF rubber duck inside my car.

Yesterday morning there were some hints of activity from the usual suspects.  I noticed WNG586 out of Henderson, NC 162.500 MHz coming in very nicely at points yesterday morning around 0650 local time, WNG686 was SIO 444 - SIO 555 at best points.    New Bern, NC also came in perfectly at the beginning of the listening sessions - KEC84 on 162.400 MHz

Logs:

162.400 MHz - New Bern, NC - KEC84 1000w TX power
162.425 MHz - UNID, possibly WZ2527 or WZ2543 (both 300w low power fill-in coverage transmitters)
162.450 MHz - Covesville, VA (Charlottesville, VA) - KZZ28 1000w TX power, mixing with WWG33
162.475 MHz - Richmond, VA WXK65 1000w TX power (local station can be heard with antenna disconnected)
162.500 MHz - Henderson, NC WNG586 300w TX power
162.525 MHz - possibly KJY99 [Accomack, VA 1000w TX power] or another station - possibly KJY86 South Boston, VA [1000w]
162.550 MHz - KHB36 and KHB37 fighting it out (as usual)

https://www.youtube.com/watch?v=UcRoGWo5Udc

At one point 162.400 got completely obliterated by local pager intermod. There are three high power pager transmitters in the downtown Richmond area, on 152.120 MHz, 152.630 MHz and 152.690 MHz - the 152.63 and 152.69 frequencies are very active and are located on top of high-rises with extremely high TX power/ERP - those two signals register as S9+60db on a base station receiver with a simple antenna.   When they transmit, the entire VHF band knows it. 

The NOAA Weather Radio website indicates that KZZ28 (162.450 MHz) is currently out of service.  It's certainly in service, they haven't updated their site.

KZZ28 must be located on top of a mountain - I can hear it consistently regardless of conditions on my VHF mobile radio.  I've used its signal to test antenna and receiver/transceiver combinations.  My handheld radios hear it just fine too, from my Motorola MTS2000 to my Baofeng UV-5Rs (with various antennas, including the stock antenna) to my Puxing PX-973UV and Quansheng TG-2UV dualbanders.

Did they have New England / Boston accents? 

6212 kHz USB is technically assigned for duplex use per the ITU "recommended" HF SSB marine channeling plan...but its often used for simplex traffic.

That's awesome, Josh.  Seems like 80m/75m is popular all over the world for non-ham stuff (military, fishing fleets, broadcasting, etc).  Doesn't the military technically have the right to use any frequency they need to use on a secondary (or primary) basis per NTIA rules?  I know they can (and do) use frequencies in the 6 meter band as part of the SINCGARS VHF FM tactical/combat net radio system. 

As far as HF goes, having the ability to transmit inside the ham bands has some obvious advantages in a serious emergency situation.

Ros mode in comparison;
https://www.sigidwiki.com/wiki/ROS
itd be hard to dance to

Lol yes indeed it would.  I've heard it on several European-based KiwiSDRs during 11m openings and sporadic-E propagation conditions.  It seems to be centered on 27.235 MHz, 27.245 MHz and 27.635 MHz. 

I know that Germany, Hungary and the Czech Republic allow use of digital modes (ROS, PSK31, etc) on 4 of their legal allocated CB channels (they have 80 channels allocated for use).  Those frequencies are 26.675 MHz, 26.685 MHz, 26.915 MHz and 26.925 MHz.  I've only done cursory monitoring of 11m activity on KiwiSDRs...and while I've heard a lot of paging and other data on various 11m frequencies, I don't think I've heard ROS on those four channels.

Heard them again this morning (0640 local time, 1040 UTC) on 107.7 MHz FM.  Noted that 107.9 MHz is quieted on my radio, they might be closer to 107.75 MHz or even 107.8 MHz. 

They appear to be switching back and forth from relaying the local NOAA Weather Radio station (WXK65 on 162.475 MHz) and playing both pre-recorded programming and what appears to be a live DJ. 

There was a translator for a local Class-D religious AM station (WLES on 590 kHz AM) on 107.9 MHz (W300DK) but they recently moved down to 97.7 MHz (W249CI), making 107.9 MHz clear again.  The closest legal station in this market is on 107.3 MHz (WBBT-FM), making 107.7 MHz a pretty good choice considering how congested the FM band has become with all the translators and repeaters on the air now.  Would-be clear frequencies (for example, 106.9 MHz) are occupied by powerhouse stations just outside the market area - in this case, its WAFX out of Suffolk, VA doing 100,000 watts 980 feet above average terrain, even though they're about 65 miles away from Richmond you can still hear them quite nicely with a halfway decent radio/antenna. 

The FM band is pretty busy, even in a medium city sized market like Richmond.  I can't imagine what the pirates in the northeast (Boston, NYC, etc.) are dealing with in terms of interference.

I recognize the melody as "its Johnny's birthday" was sung by george harrison. Glad you got a recording.

The music has been going on for hours. Probably all night.
I had heard radio signals like that before, many year ago.

The signal is DX, by propagation

Looks like you've found yourself an 11 meter broadcaster, of sorts.  Music played on the 11m band / CB band on a regular basis. 

Have you heard the same signals on other frequencies or have they always been on 27.175 MHz / 27175 kHz and in AM mode? 

505
Never heard ROS sound like that.

Right.  Maybe somebody playing music on 27.175 for fun?  Or as part of an "interval signal" of sorts to indicate that the channel is about to be used? 

I remember seeing a video on YouTube made by a European CBer - he was hearing Arabic music and melodies on several frequencies on the "low channels" on 26 MHz, I believe 26.785 MHz, 26.795 MHz, 26.865 MHz or nearby frequencies, all in FM mode.  He wasn't sure where they were coming from either.  After the music there would be an OM speaking Arabic.  Good signals too.

10/11 meters / Re: Delayed Audio
« on: August 22, 2019, 1314 UTC »
A couple of weeks ago I was scanning the 26/27 Mhz bands and came across a lot of chatter on one channel. Don't recall the exact frequency. I think it was probably CB from Europe, maybe Italian. The audio was difficult to hear as it sounded like several people talking at the same time.
I realised that I was hearing the same person talking but also on a delay of about 3 seconds. Everything he said was repeated but slightly weaker and quieter about 3 seconds behind.
I know that some OPs use reverb sometimes but this definitely a delay  of several seconds.
Anybody have any idea of what would cause this?

Lots of high power AM Italian guys use echo and reverb (sometimes to an extreme).  They're often found on "canale 45" or 27.465 MHz / 27465 kHz AM mode.  I know they use other frequencies as well, but 27.465 seems to be their favorite, sort of like 27.025 MHz is to the USA and 26.705 MHz / 26.715 MHz / 26.725 MHz are to the Latin American world. 

During band openings in years past I've heard tons of echo/reverb-laden signals from Italy on 27.465 AM.

Utility / Re: Red Thunder calling First Sealord 4028 USB
« on: August 22, 2019, 1311 UTC »
1240 Red Thunder calling First Sealord several times with nothing heard.
1243 Sealord answers.  Red Thunder acknowledges and out.

The frequency doesn't match up with any of the MARS nets I've heard, and both Red Thunder (male) and First Sealord (female) sounded much younger than the typical MARS op, so I assume it's active or reserve military.

Edit: I found this doc that lists First Sealord as USS Winston S. Churchill (DDG 81) and Red Thunder as possibly USS Ramage (DDG 61)

Nice catch re: US Navy voice net on 4028 kHz USB.  My first guess would have been MARS given the frequency used.

Shortwave Broadcast / Re: WJHR now on 15550 USB
« on: August 22, 2019, 1310 UTC »
There was a warc move to get hfbc to all ssb mode by a certain date that I presume is long past. Odd how so few have moved to ssb even if due the energy savings.
Then again most listeners to hfbc are using a portable sw set with simple diode rectification and can't copy ssb, or if they can it'd be tedious to have to bfo tune every bcast.

Exactly.  Even though SSB-capable portable shortwave receivers are cheaper now than they were 10 years ago, I imagine that most listeners in 2nd/3rd world countries are using basic AM mode only receivers (or AM/FM/SW portable radios) for shortwave reception.

10/11 meters / Re: Loop melody in 27Mhz
« on: August 21, 2019, 1954 UTC »
I know the ROS data mode is used on CB channels 24 and 25 - 27.235 MHz / 27235 kHz and 27.245 MHz / 27245 kHz as well as 27.635 MHz / 27635 kHz...and it has a very melodic sound. 

Youíre listening to channel 18 - 27.175 MHz / 27175 kHz so Iím not 100% sure.  The ROS mode is popular on 11 meters / the 27 MHz band in Europe...where are you located?

Virginia House Radio 107.7 FM still going strong this afternoon local time in Richmond, VA.
