6900 kHz LSB and 6910 kHz LSB going strong with Spanish speaking freebanders or outbanders, stations heard checking into the "net" on 6900 LSB at 0054 UTC and similar procedures heard on 6910 kHz LSB 0055 UTC.

Received via the Westminster, MD KiwiSDR. 

4935 kHz 4.935 MHz USB voice, SS Spanish speakers, lots of proper radio pro-words heard.  Possibly pescadores or outbanders.  Hiding within the 60 meter shortwave broadcast band.  Not nearly as busy as the other frequencies logged recently.  Lots of "copyando" heard. 

SIO 222 or so, received via COMMSIGMA KiwiSDR on the CT/MA border.  As of 0052 UTC, the frequency seems to be clear, stations possibly QRT at this time.

6203.3 kHz USB 6.203.3 MHz USB SS OMs with lots of chatter on frequency.  6203 kHz is a valid 6 MHz marine frequency, going by the time of night, this is likely coming out of South American or Caribbean waters. 

Receiver is the COMMSIGMA KiwiSDR on the CT/MA border.

Dodah Net - Dolittle Net - Cruiseheimers Net - Yachtmen's Net - EE English language marine HF maritime mobile HF-SSB

8 MHz band frequency 8152 kHz 8.152 MHz USB voice SSB

Yachtmen talking about maritime stuff, "how many days did they give you for immigration" - "its right there on the dock" good signals with various OMs and YLs talking about conditions in the Caribbean, sailing conditions and then discussion to which frequencies (HF) and channels (VHF) good weather forecast broadcasts can be heard on at/near which islands in the Caribbean.  Discussion of VHF marine radio ranges and the "sunrise effect" on VHF channels.  "He monitors 72, but they do the initial call on 16 and then switch to another channel so I assume its 72" - mention of 4 MHz marine frequencies as well.

"Cuban Key" (?) possible location mention.  Looking at the KiwiSDR waterfall, I see over a dozen SSB QSOs in the 7900 kHz to 8500 kHz range, 8000-8815 kHz is all marine stuff and looks like the 8 MHz band is performing well.  Receiver is the COMMSIGMA KiwiSDR on the CT/MA border.  Same frequency as the Cruiseheimers Net 8152 kHz USB.  Stations IDing with the name of their boats.  English language.  Lots and lots of other marine SSB traffic on the band right now...8 MHz is busier than 6 MHz.

Lots of QSOs nearby, including a weaker one in Spanish on 8150 kHz USB and another, much stronger one in Spanish on 8146 kHz USB.  Weak SSB voice traffic on 8149 kHz USB as well. Minor QRM from the USB voice traffic on 8150 kHz. 


8152 kHz is a simplex only or cross-band duplex only frequency in the marine mobile service.  Either ship-to-ship comms on frequency 8152 kHz or cross-band with 4051 kHz (channel 18).  Shared with fixed service in the 4000 kHz to 4063 kHz band and the 8000 kHz to 8195 kHz band.  For this net it appears that all users were using simplex mode only for ship-to-ship comms, which seems to be the primary mode of operation for most marine users, especially the yacht and sailing nets I've heard on the 4 MHz, 6 MHz, 8 MHz and 12 MHz.

From the USCG MF/HF SSB frequency information pages:

The following channels in the band 4000-4063 kHz and 8100-8195 kHz may be used:

for supplementing ship-to-shore channels for duplex operation;
for Intership simplex (single-frequency) and cross-band operation;
for cross-band working with coast stations;
for duplex operation with coast stations working in the band 4438-4650 kHz or with Channels 834, 835, 836 and 837;
for ship-to-shore or shore-to-ship simplex operations (8100-8195 kHz only).

4000 kHz - 8101 kHz  - channel 1
4003 kHz - 8104 kHz  - channel 2
4051 kHz - 8152 kHz - channel 18

More of the same in the 6-9 MHz region this late afternoon/early evening.  Lots of Spanish and Portuguese voices on various frequencies in the fixed/mobile bands.  Presumed land-based comms although they could be maritime HF SSB operating out of band.  Considering how busy the 6 MHz and 8 MHz marine bands are right now it would make sense.

7865.5 kHz USB (the OM seems closer to 7865.6 kHz USB), OM and YL having a QSO
7900 kHz USB - weak QSO in Spanish, very difficult to make much out at the moment

7790 kHz USB 7.790 MHz USB - OM and YL talking, some distortion, weak
7793.5 kHz USB 7.793.5 MHz USB - OM and YL talking, YL reading several series of numbers, then "wooo!" and the OM replied with "awww yeah!" - OM talking about issues with the car and cost of repairs at 2207 UTC.  Sounds like a husband and wife having a QSO?  Possibly land-based "radiotelephone" networks - there are several other frequencies nearby that are also active. 

Both 7790 USB and 7793.5 USB are just outside the splash from the WRMI blowtorch shortwave broadcast signal on 7780 kHz.

6282 kHz USB 6.282 MHz USB - HF marine SSB frequency active with an OM and a YL having a QSO.  Weak, but there.  Possibly fisherman talking to his wife back home.  Received via COMMSIGMA KiwiSDR on the CT/MA border.

Mixing with QRM from 6215 kHz USB and 6215.5 kHz USB, all three frequencies are busy right now...6215 USB is the 6 MHz marine calling/distress frequency but is heavily used by Latin American fishing fleets as a home channel or chat channel.

6 MHz is busy this evening.  Receiver is the COMMSIGMA KiwiSDR on the CT/MA border.

Sounds like New England accents, some salty language...one of the two operators seems closer to 6212.1 kHz.  Talking about hypothermia at 1715 UTC.

Marine traffic fishing fleets Gloucester or similar locations in MA.  "fuckin' guys" and similar phrases heard often.  6212 kHz USB 6.212 MHz USB 6212 USB 

27255 kHz 27.255 MHz 27258 27253 USB LSB via COMMSIGMA KiwiSDR

FSK data signals, at least two different stations (going by difference in signal strength) with some QRM from AM CB traffic down in the noise at 1700 UTC (1200 noon local time) COMMSIGMA KiwiSDR on the CT/MA border.  The band seems closed at this time so I am presuming this is the same 27.255 MHz data link FSK data burst network logged back in December.

17330 kHz 17.330 MHz USB -

OM speaking Spanish rapidly...can only hear one side of the QSO at the moment.  Noted activity on 16 MHz and 17 MHz late this morning on the US east coast.  Received via COMMSIGMA KiwiSDR on the CT/MA border just shy of 1700 UTC.

13, 18, 22, cambio!

OM reading numbers in Spanish on 14500 kHz USB 14.500 MHz USB outbanders or freebanders or maybe more fishing fleets.  "uno trenta cinco, cambio!" (1 30 5, over).  At least three different stations chatting away on 14500 USB, sometimes talking on top of each other, which lends itself to the typical pesky profile.  No engine noise or anything else heard in the background, could be land-based transmissions.  The proximity to 20 meters also lends itself to maybe these are radio amateurs operating out of band....

9218 kHz 9218 USB 9.218 MHz USB SS OMs, pretty weak but this doesn't sound like air traffic control to me.  Presumed fishing fleets or freebanders/outbanders.  SIO 222 via COMMSIGMA KiwiSDR on the CT/MA border

Spanish speaking traffic on 8756 kHz 8.756 MHz USB voice.  SS OMs, with some slash QRM from the USCG WX broadcast on 8764 kHz USB.  SIO 333 or so.  Sounds like South American fishing fleets in the 8 MHz band this morning.   The more talkative of the two OMs is reading several series of two-digit numbers "vente uno, trenta dos, gambio!" etc...the other station simply replies that he receives him.  Could be something like GPS coordinates

Two OMs talking with minor QRM, talking about charts and sat images of "deep water" and "at noon you can really see the deep dark water" "we tried that back in '13" - very good signals for both stations on the COMMSIGMA KiwiSDR.  Minor QRM from other marine traffic, presumably.  Propagation conditions to the Caribbean seem to be very favorable at the moment.
