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.

Some interesting logs here, including the 29.750 MHz 29.75 MHz, 29.800 MHz 29.8 MHz and 29.900 MHz 29.9 MHz pager signals coming in...same with 30.900 MHz, 31.320 MHz and the 31.1875 MHz frequency (maybe offset from 31.180 MHz, 31.190 MHz or 31.200 MHz..or it's coming from a country that uses the 12.5 kHz steps for that particular band plan. 

I remember reading about Canadian pager systems operating in the 29.8 MHz to 30-something MHz band, 10 kHz steps.  Of course, the freebanders / outbanders using 29.875 MHz is another interesting one.  To be fair, the 25 MHz, 26 MHz and 27 MHz bands were extremely busy.  Lots of activity in the 29.000 MHz to 29.700 MHz portion of 10m as well. 

But the 26 to 28 MHz band was just nuts.

R/C channels:


26.995 MHz 26995 kHz - At 1705 UTC tuned back in, hearing two FSK signals (26.995 MHz USB, center frequencies 26.996 and 26.997 MHz...now hearing what sounds like ROS data mode mixing in (again on 26.995 USB).  Numerous data signals on or around 26.995 center freq, 26.990 MHz to 27.000 MHz or so)

27.045 MHz 27045 kHz - Weak AM voice heard, sounds like a taxi cab dispatcher

27.095 MHz 27095 kHz - modulated FSK signal right on 27095.0 kHz, along with data bursts (similar to the ones usually heard on either side of 27.255 MHz) noted.  Several AM voice signals also heard, Spanish language

27.145 MHz 27145 kHz - 27145.2 carrier noted at 1711 UTC...unmodulated carrier or CW signal...then nothing.  At 1712 UTC, a multi-carrier FSK signal appeared on frequency, dial frequency 27.144 MHz USB or 27.143 MHz USB

27.195 MHz 27195 kHz - Noting a mixture of AM voice, the usually heard FSK data signal bursts and weak FM voice (Spanish language) on 27.195 MHz (R/C channel 19A).  Later SSB voice signals (27.195 MHz USB - Spanish language) also coming in with the mix!  Most of the signals heard here are regular AM voice signals mixing in with FSK data bursts

27.255 MHz 27255 kHz - Several FSK data bursts noted (usually with signals on 27.252 MHz or 27.253 MHz on the lower side of center frequency and again on 27.256 MHz or 27.257 MHz on the upper side of center frequency).  27.252 and 27.256 both very strong, another (different bandwidth) FSK burst noted on 27.254 MHz (possibly off-frequency).  LSB voice noted as well 27.255 MHz LSB mixing with AM voice and the data bursts.  Checked 27.255 MHz again at approx 1930 UTC and the usual data bursts are still there, but a bit weaker than before.  As expected, AM voice signals are also present on frequency (after all, 27255 is legal CB channel 23.

1335 UTC noting activity on 27555 USB as well as QSO on 27520 USB, 27535 USB and 27525 USB

French language on 27520 USB at 1339 UTC, fair to good signals

"it was the 28th of February, Monday, we did that....on frequency 27.540 MHz, Andy, you're right here" on 27.525 MHz USB, mention of '26 division' (UK)

Now some weak FM on 26.655, some QRM from the data signal on 26.650 MHz.  26695 and 26745 both getting stronger

Now hearing SSB voice on 26.450 MHz USB with some POCSAG or FSK data underneath it.  26.445 USB also active.  Possibly Polish language?  Could be indicators of a European band opening.  FM signal on CB channel 3 - 26.985 MHz fading in at 1350 UTC, sounds like UK? 

Italian on 27.645 USB at 1351 UTC
