35.280 pl 151.4 Mil Coms - this is (or should be)
35.275 MHz with the 150 Hz tone. Of course, every scanner decodes it as 151.4
Todays logs from 7 am CST to 10 am CST
32.550 pl 151.4 MIL COMS - I've come across this one a few times in the past too. When it comes in, I sometimes hear what I believe are military police comms on 34.050 MHz, 34.150 MHz and a handful of others.
30.020 pl 151.4 Mil Coms - 30.025 MHz FM 150.0 Hz PL tone - this seems to be a popular air to air and air to ground frequency for military users
Todays logs:
47.47 pl 151.4 Mil Coms radio checks new one for me - frequency almost certainly 47.475 MHz. Nice catch though!
30.220 CW ID Hospital in Canada found youtube video of it new to me! - this is another good one. See also: 30.020 MHz and 30.420 MHz.
Some very nice catches, especially 35.275 and 47.725 MHz. I know that local (to me), air to air comms take place on 41.525 MHz and 49.725 MHz (both FM, with the usual 150.0 Hz tone that shows up as 151.4 Hz tone). The 25 kHz "offset" frequencies (including, say, 30.025 MHz) are not as common - it seems, as the 50 kHz spacing or even 100 kHz spacing frequencies, but they are absolutely in use.
The hospital paging system catch on 30.2200 MHz is another good band opening indicator. From my reading / research, 29.840 MHz, 30.020 MHz and 30.420 MHz are used for the same purposes. However, I can only find confirmation of 30.02 MHz and 30.22 MHz (as far as loggings go, all from DXers). FWIW, 29.84 MHz and 30.42 MHz all "match" the apparent 200 kHz spacing between on site hospital paging frequencies, so it does at least make some sense.
Speaking of on site hospital paging frequencies, I heard the UK on site hospital paging frequencies 31.725 MHz, 31.750 MHz and 31.775 MHz again recently, with the usual hodgepodge of CTCSS tones. I can confirm that they do use voice on those frequencies (as in, making voice pages), however, the vast majority of transmissions are, well, data (paging).
The UK apparently also use 31.150 MHz and numerous frequencies in the 49 MHz range (eg. 49.0625 MHz, 49.1875 MHz, 49.375 MHz, 49.425 MHz, 49.450 MHz, 49.475 MHz, 49.4875 MHz) for on site paging - plus the 26 MHz band...the 26-28 MHz band and 29 MHz paging frequencies are another story, though - due to the sheer number of paging and datalink systems on the 26-28 MHz band, especially out of Europe. Yep, here we have the RCRS frequencies, there it is like that, if RCRS was used as a standard on site paging system for numerous facilities, including hospitals.
For band opening indicator purposes - I can confirm that 29.800 MHz FM, 29.900 MHz FM, 30.100 MHz FM, 30.875 MHz FM, 30.900 MHz FM and 31.320 MHz FM are all used for on-site paging somewhere in Europe.
Double VHF low band DX bonus points for hearing the French EPAR polytone data link signals on 31.325 MHz and the POCSAG paging signals on 31.320 MHz mixing together.
Okay, I can confirm that 30.875 and 30.900 are used by Spain (not able to confirm the other ones, but it seems that when 30.875 / 30.900 are coming in, 29.800 and 29.900 are as well. I've heard some sporadic paging signals on 29.700 MHz, 29.750 MHz and 29.850 MHz when the band is really rolling - that is, when 29.8 and 29.9 are just booming in.
At those points, Spanish paging signals on 40.775 MHz, 40.825 MHz, 40.850 MHz, 40.875 MHz and 40.900 MHz are also noted. There's at least one system (presumably also in Spain) on 40.900 MHz that transmits a FM carrier when it is "idle", includes a BEEP BEEP BEEP BEEP transmission at somewhat regular intervals and transmits a 110.9 Hz PL tone, which is interesting. Italian paging signals can be found on 40.0125 MHz, 40.0375 MHz, 40.0625 MHz, 40.0875 MHz and numerous others.
