1432 German OM on ch 35 in FM mode
1434 27555 USB Munich Germany

1437 27360 LSB German accent EE OM
1446 27520 USB Sardinia
1458 26905 FM - German It's interesting how geographically narrow many of these openings are, like a pipe from here to Germany. Reminds me of DGPS and NDB DX down around 300 kHz.
1500 26815 FM
1501 27025 CB Ch 6 FM - German OM
1501 26955 FM German

Absolutely.  26100, 26150, 26200, 26235 (and other offsets like 26237.5, 26238) 26250, 26350, 26400, 26435, 26440, 26450, 26550, 26555 (yes, even though 26.555 LSB is super popular) 26600, 26605, 26610, 26625, 26635, 26645, 26650, 26655, 26695, 26700, 26705, 26745, 26750, 26755, 26845, 26850, 26855, 26865, 26900, 26935 and many others are all known 26 MHz band paging frequencies.  The lower 26 MHz ones are apparently UK hospital pagers and used in other parts of Europe as well.  26600 had a very strong signal on it at points, and was transmitting an unmodulated carrier "idle" when there wasn't data being sent.   

26950 26.950 MHz and 26955 26.955 MHz also apparently heavily used.  There are dozens of others, including in-band frequencies - especially around 27100, 27150, 27300, 27350 and 27360.  Same with 27450, 27500 (and 27505), 27550 and 27650.  Not sure of their origin.  Paging and data links on 26945 and 26960 are apparently out of Russia and likely used elsewhere as well.  There are also pagers operating on 29750, 29800, 29850, 29900, 29950, 30000, 30020 and 30025 all appear to be coming out of Europe.  I know that at one time anyway, 30.020 MHz and 30.025 MHz often had POCSAG signals on them, apparently out of Canada.  Not sure if they're still using those frequencies as well or not.

So I've checked this KiwiSDR (located in the UK) daily for the past few days and every day, regardless of band conditions (which, lately have been good), I've noticed that, in addition to the pagers and data links in the 29.7 to 30 MHz band...

there are guys hanging out on 29.875 MHz FM.  Sounds like French language.  Maybe it's not.  Maybe it's Portuguese or Italian?  FM signals are in the 8-12 kHz bandwidth ballpark.  I think it's Italian.

Carrier frequencies noted:

29875.07 kHz
29874.9 kHz
29875.1 kHz
29875.2 kHz
29874.8 kHz
29875.03 kHz


Lots of strong pagers on

29750 kHz 29.750 MHz 29.75 MHz
29800 kHz 29.800 MHz 29.80 MHz
29850 kHz 29.850 MHz 29.85 MHz
29900 kHz 29.900 MHz 29.90 MHz

With 29.8 MHz and 29.9 MHz being the busiest, both 29.800 MHz 29.900 MHz have basically nonstop POCSAG signals on them.

There are strong FSK signals on 29.878 MHz and 29.870 MHz and a dozen other frequencies in the 29700 kHz to 30000 kHz "sliver". 

I know most export rigs cover 25615 to 30105 (that extends to 30110 or 30115 so 30.105 MHz 30.110 MHz or 30.115 MHz and in some radios the coverage goes up to 30.555 MHz or 30.560 MHz, 30.565 MHz or 32 MHz.  So 29.875 MHz is a legit export radio/freebander frequency, but it also matches up with the 27.500 MHz to 39.475 MHz (25 kHz steps) Chinese fishery radio service (27.500 MHz to 39.475 MHz, FM voice - 29.875 MHz matches up with that channel plan).

So these guys are either a fishing fleet or freebanders....will try and get a video clip with some audio at some points and will include it in this post.  There's some interesting stuff in the 29.7 to 30.0 MHz band.
