Haven't radio buoys (driftnet bouys, etc) been operating in the 1800-3000 kHz and 25000-28000 kHz regions for decades now?

I suppose that just means they've been operating illegally.

One of my first radios was a Pearce Simpson "Super Cheetah" 40 channel AM/SSB mobile.  What a great radio that was.  President equipment is still sold in Europe and is now recently available in the USA (again) as well.  I used to have a Superstar GR (re-branded President Grant) with low-mid-high bands AM/FM/SSB and a 6-digit frequency counter.   The radio did 26.515-26.955 MHz (low), 26.965-27.405 MHz (mid) and 27.415-27.855 (high) with amazing modulation.  I ended up selling it and buying a Taiwanese Superstar 3900...even though the Superstar GR/President Grant was also made in Taiwan...I wanted a radio that did 25615-28305 instead of 26515-27855.  

There's a lot of Latin American taxicab companies (and of course trucking companies everywhere) that like to use the lower frequencies.  The lower bands are also very popular with hunters in the USA.  In fact, Ranger/RCI made two radios called the Connex Deer Hunter and Connex Coyote Hunter.  The Deer Hunter did 26515-27855 AM/FM with high/low power switch (Ranger knew most hunters are connecting their radios to amplifiers) and the Coyote Hunter did 25615-27405 (so 3 bands of lower channels and the regular CB band as the highest band).



I live in a state where deer and duck hunting is extremely popular.  Most hunters have export radios and VHF marine radios installed in their trucks.  Hunters illegally using the VHF marine channels is a significant problem.  I've heard the US Coast Guard get on VHF marine channel 16 and tell hunters to vacate the frequency because they were causing interference to the marine emergency frequency.  During deer hunting season I can scan the VHF marine channels and hear traffic on 5-10 channels at once, all of the traffic being hunting clubs talking to each other. 

It's interesting that you mention 8918 kHz USB.  Have you tried the other, lower frequencies for New York Radio?  Those in the 5-6 MHz region? What about the US Coast Guard stations NMN (Chesapeake, Virginia), NMG (New Orleans, Louisiana), NMC (Point Reyes, California), NOJ (Kodiak, Alaska) and NMO (Honolulu, Hawaii)?

I hear NMN and NMG on a daily basis, frequencies and schedules can be found here: http://www.nws.noaa.gov/om/marine/hfvoice.htm


I'm surprised the Australian UHF CB band isn't more popular.  The 22 channel FRS/GMRS "combination radios" are very popular in the USA, and even though licenses are required to use the GMRS channels and to transmit more than 0.5 watts on FRS channels 1-7, the vast majority of users aren't licensed and FCC enforcement is basically zero.  GMRS repeaters can be found in almost every city in the USA, with some cities having multiple repeaters on the same channel.  

Since FRS/GMRS are the American version of a "UHF CB" service, the American Multi-Use Radio Service (MURS) could be referred to as "VHF CB".  Due to the heavy pirating of VHF business band frequencies by unlicensed users, the FCC released 5 frequencies to the general public for unlicensed use.  Unlike FRS/GMRS or regular 26-27 MHz CB, MURS allows use of AM, FM, and various digital modes and is heavily used for short-range data links as well as on-site communications at schools, construction sites, etc.

We certainly could.  There's something to be said for the older-generation CB/11 meter export equipment, but the modern generation Chinese equipment is catching up.  Slowly, but it is catching up. 

I spend most of my radio time on VHF/UHF and what I'm not spending on VHF/UHF I'm spending chasing down "rare" signals on HF (I'm including 11 meters under "HF").  Sometimes its a lot more fun to find an illegally-operating fishing fleet than it is to find a ham station running 1500 watts into a beam antenna on 20 meters :D

2554
Strong Spanish language traffic on another interesting frequency.  6 5 4 3 2...now that's easy to remember.  Just like 6777.7 kHz or 6888 kHz, etc.  6543.2 kHz is another case of fishing fleets using HF aircraft bands (in this case, the 6 MHz aeronautical band 6525-6765 kHz), not to mention their use of LSB instead of USB. 

Two OMs talking rapidly with long breaks of silence.  Appears to only be two stations (as opposed to many peskie loggings, where there's 3+ stations, often with several stations transmitting at once. 

I tuned away at 0647 UTC and the frequency was clear when I tuned away.

2555
Yet another 5 MHz aeronautical band pirate/peskie/who knows logging.  This time its 5540 kHz (compare to previous logs for 5510 kHz USB and 5534 kHz USB).  Googled 5540 kHz and 5540 USB and found nothing but information on shortwave broadcasters who use (or have used) 5540 kHz.  Nothing about aircraft or military users of this frequency. 

The 136th edition of the Spooks Newsletter NSNL 136 lists the frequency 5540 kHz as being used by station S30.

Peskie-like chatter in Portuguese with some sort of faint data signal underneath the voice traffic.  Very long winded transmissions (also typical for peskies) with very little to no radio discipline, which leads me to believe that its not aircraft stations using a different language or military/government/diplomatic traffic.

2556
Two romance language stations (I put Spanish in the title but after listening for a bit I think it may actually be Italian) chatting away.  Another unlisted HF aircraft frequency being pirated by non-aircraft users.  SIO 333 at best with static crashing and very minor fading.  One of the stations has some sort of background chatter, possibility indicating it being a marine-based transmitter. 

Falls within the 5450 kHz - 5730 kHz 5MHz HF aircraft band.  Quite close to the 5505 kHz USB MWARA frequency for New York Radio. 

2557
Doing some late night (er...early morning) band scanning and came across another "pescadore net" on 5534 USB.  5534 kHz lies within the 5450 kHz to 5730 kHz aeronautical band but 5534 does not appear to be an assigned on-route HF aircraft frequency. 

Radio traffic is similar to the standard peskie two-way traffic heard in the 6-7 MHz region and on other frequencies.  Heavy static crashes and relatively weak signals gives these stations a SIO 222. 

2558
Two groups of marine stations chatting away on 6230 kHz USB and 6270 kHz USB.  6230 kHz is one of the few 6 MHz marine band [6200 kHz - 6525 kHz] simplex only channels (according to the ITU channel plan anyway). 

6230 kHz USB - Spanish language
6270 kHz USB - Italian language

Both nets are coming in nice and strong late this evening (US East Coast).  Nice to see marine users actually using legal HF marine frequencies within the legal HF marine bands!   

2559
Tuning around the 3-8 MHz region this evening, right at the bottom of the 6 MHz marine band and I came across a simplex QSO on 6200 kHz USB.  Per the ITU HF SSB maritime frequency channel plan, 6200 kHz is ITU channel 601 and is a "duplex" channel (split-frequency) paired with 6501 kHz.  6200 kHz USB is the ship transmit frequency and 6501 is the coast transmit frequency.  6200/6501 is listed as one of the "USCG Calling" channels which makes sense given the fact that the US Coast Guard uses 6501 kHz USB for marine weather transmissions.  

The users are speaking Spanish and are operating in single-frequency only (nothing heard on 6501 kHz).  Per ITU channel plan, only 6224 kHz, 6227 kHz and 6230 kHz may be used for simplex operation.  

Maybe I've stumbled upon some fishermen actually using real legit MF/HF marine radio with the pre-programmed ITU channels!  [gasp!]

Still going strong at 0332 UTC.  

2560
Likely.  Which frequencies did you notice activity on? 

2561
6750 kHz USB - Unknown language, likely Spanish...strong QRM from data signal on ~6752 kHz
6763 kHz USB - Spanish, very strong signals with ute QRM
6771 kHz USB - Spanish - with very heavy QRM from Old Time Radio on 6770 kHz AM
6868 kHz LSB - Portuguese
6870 kHz AM/CW - station tuning up
6873 kHz LSB - Portuguese
6873 kHz USB - Spanish, sporadic signal right at noise floor
6895 kHz LSB - Spanish, very strong signals with some static crashes.  At least 3 different stations talking in a "net"
6900 kHz LSB - Spanish - active as usual
6915 kHz LSB - Portuguese
6919 kHz LSB - Portuguese, sporadic signals
6925 kHz LSB - Portuguese, very strong signals some S7-S9 with QRM (stations walking all over each other, etc)
6960 kHz LSB - Spanish
6986 kHz USB - Unknown language, sporadic signal

2562
Hearing bits and pieces of Old Time Radio pirate on 6770.0 kHz AM.  Pescadore QRM from two-way traffic on 6771 kHz USB making reception difficult.  SIO 333 at best.

2563
Hearing bits and pieces of audio, with some strong peaks of music.  6876 kHz AM (looks to be exactly 6876.2 kHz AM).

Thanks TCS!

2564
I miss listening to UK FM CB and WPAS/CADS church transmissions on 11 meters as well as the pileups on 27555 USB, etc. Seems like today's log on 27495 LSB was a bit of a fluke. Possibily some minor sporadic E propagation. I checked 27515 LSB, 27515 AM, 27025 AM, 26925 AM, 26555 LSB and the 26705-26725 frequencies that are usually blowing up during openings and heard nothing. 26225 USB, 26555 LSB and 26585 AM are all indicative of a band opening to Latin America and they were all quiet.

Fingers crossed for more 11 meter band DX as the spring season rolls on!  8)

2565
Hearing faint Spanish language traffic on 27495 USB (complete with roger beeps!) at 1735 UTC.  Scanning the rest of 11 meters and hearing nothing but local AM CB traffic and occasional station calling CQ DX on 27385 LSB. 

Maybe the sporadic E season is finally upon us!
