10/11 meters / Re: Very strong RC signal 27147 kHz 1715 UTC 6 Jun 2020
« on: June 25, 2020, 1405 UTC »
What sort of signal? FSK?
I noticed tones and music (as well as regular AM voice traffic) during one of the many recent band openings on 27145 kHz / 27.145 MHz as well as 27195 kHz / 27.195 MHz.

VHF/UHF Logs, including satellites and radiosondes / Re: 49 MHz Room Monitor / Open Mic With Some Serious Range 49.830 MHz
« on: May 06, 2020, 2300 UTC »
This seems to be a baby monitor used for an old folks' home or to monitor an invalid neighbor or elderly family member. I did some more listening today with a better antenna. Previously I was using a 1/4 wave VHF antenna tuned for the 140-160 MHz region, today I used a ProComm JBC1500 60" base-loaded CB antenna tuned for just below CB channel 1, 26.6 MHz or 26.7 MHz or so, as a 1/4 wave. That makes almost a half wave at 49 MHz....and what a difference that made. I could hear the 49.830 MHz signal nearly full scale for 1500+ feet in all directions, extending out to 3000 feet or so before the signal completely dropped off.
I also was able to listen to it on a purpose-built 49 MHz FM walkie talkie - specifically a Maxon PC-50 (same thing as a RadioShack / Realistic TRC-512) 5-channel 49MHz handheld, with 49.83 MHz as Channel A. I got took two more videos:

49.83 MHz, pretty wide signal (sounded good on 49.825 MHz and 49.835 MHz in addition to 49.830 MHz). I was using a VHF high band 1/4 wave antenna, which is certainly not the best antenna. Noted at least part of the signal on 49.840 MHz too.

It sounds like somebody has a room monitor just on, you can hear a TV or radio in the background...at 0:59 or 1:00 in you can hear somebody say "oh you ready?". More chatter around 1:30 and 1:40. Interestingly enough, my scanner actually decoded too different CTCSS tones - 192.8 Hz and 196.6 Hz, on frequency.

FM Free Radio / 107.7 FM Virginia House Radio - Richmond, VA 6 May 2020
« on: May 06, 2020, 1346 UTC »
Virginia House Radio coming in very nicely this morning on 107.7 MHz FM in downtown Richmond. Music - faded into a relay of the local NOAA Weather Radio All-Hazards station WXK65 (162.475 MHz).
Receiver is a factory stock Toyota AM/FM car radio with factory FM whip antenna (a real 1/4 wave steel FM whip antenna).
I managed to get two videos of the activity on 107.7 MHz:

10/11 meters / Re: UNID 28100 FM 2300 UTC 21 Mar 2020
« on: March 22, 2020, 1446 UTC »
How far off frequency? Like 28097 kHz or 28099.1 kHz? I know that 28085 / 28.085 MHz is Channel 19 "up two bands" on export radios - 27.185 MHz - 27.635 MHz - 28.085 MHz + 10 kHz switch gives you 28.095 MHz.
Export radios that cover 25-30 MHz or so (usually 25.615 MHz - 30.105 MHz, 26.065 MHz - 28.755 MHz or 25.615 MHz - 28.305 MHz) are very popular with fisheries.
Of course, they could also be running one of the Chinese fishery 27.500 MHz - 39.500 MHz FM fishery radio system, 480 channels 27.5 MHz - 39.475 MHz. 25 watt radios, FM voice 16K0F3E/16K0G3E emissions with 25 kHz steps (27.500 MHz = channel 1, 27.525 MHz = channel 2, etc.) So 28.100 MHz FM fits within that channel plan perfectly as far as frequency and mode. I could see one of those radios being 500 Hz off-frequency or so without any issue since they're running regular "20 kHz FM" or "25 kHz FM" - what's used for amateur radio and VHF low band land mobile communications.

The FT-801 radio and similar radios are not doubt sold by fisheries equipment suppliers in Portugal, Brazil, etc.
Apparently QRM on the 10 meter band from AM/FM export radios covering 25.615-30.105 MHz and FM fishery radios covering 27.5-39.5 MHz is extremely problematic for ham operators in Asia, since when you look at those channel plans (10 kHz steps 28.005 MHz, 28.015 MHz, 28.025 MHz, 28.035 MHz, etc. AM/FM/SSB and 25 kHz steps 28.000 MHz, 28.025 MHz, 28.050 MHz, 28.075 MHz, 28.100 MHz, 28.125 MHz, 28.150 MHz, 28.175 MHz, up through 29.575 MHz, 29.600 MHz, 29.625 MHz, 29.650 MHz, 29.675 MHz, 29.700 MHz, 29.725 MHz, 29.750 MHz to 39.400 MHz, 39.425 MHz, 39.450 MHz, 39.475 MHz, etc.)

According to the needs of fishermen users, this unit adds an AM radio function to facilitate listening to weather broadcasts; Setting 4 Communication channels - 4 channels on duty (channels 221, 231, 236, 238), greatly improving the data signaling connection rate; built-in GPS module to complete positioning and navigation functions.

It would appear that the Chinese have a pretty extensive network set up for this band, much like the Japanese and South Koreans with their 26 MHz / 27 MHz AM and SSB fishery radio systems. Multi-channel dual watch function for channel 221, channel 231, channel 236 and channel 238, which, if straight channel numbering is used, equal 33.075 MHz, 33.275 MHz, 33.400 MHz and 33.450 MHz.
Therefore, if these guys were using FT-801 radios or similar Chinese spec gear on 28.100 MHz FM, that would equate to channel 25 on these radios.

Running DV on 11m is certainly an option. The OP 45auto opted for VHF MURS comms instead.
It would be relatively easy to make a mixed mode FM / DMR or FM / P25 digital with encryption system on the MURS frequencies.

Massive network of village radio stations - the "chanting nets". 6990 kHz, 6995 kHz, and of course, 7000 kHz.
I'm sure some of them are using higher-end amateur and professional-grade HF-SSB gear. Wouldn't surprise me if there were some stations using military HF radios too.
