Equipment / Re: Need halp wif antennaz
« on: June 20, 2013, 1041 UTC »
For receive only, 30 ft / 10 meters of wire should work OK throughout the HF spectrum.  I've had good reception on antennas that were around that length.

You'll probably get more gain with a longer wire, though -- especially on the lower frequencies.

Other / Odd happenings on 7180 khz; 0321 UTC, 6/17/13
« on: June 20, 2013, 1019 UTC »
Usually I don't hear much CB-like activity on the 40 meter ham band.  Generally, that sort of activity seems to be left to the 11 meter spectrum, and maybe one frequency on 20 meters that's famous for guys playing music, swearing, etc.  Aside from the Indonesian pirate chanters, and a few stray signals like the Russian single letter beacons, 40 meters generally seems pretty 'normal'.

Well, this last Sunday I tuned into some loud music in USB on 7180 khz.  After clarifying it, it turned out to be Motley Crue's "Ten Seconds Of Love", which was followed by a lot of angry exchanges and cussing by several different operators (including a guy who gave out his call letters).  Soon afterwards, Van Halen's "Little Dreamer" was played.  Then some dead air, then the music player made some random comments about a Magnum CB radio, Arizona, a mention of Father's Day, and "you're all gonna die." 

Then "I'll Wait" by Van Halen was played, followed by some more angry exchanges, including a ham telling the music DJ that he was ruining ham radio for everybody else, and he used to beat up "punks" like that in high school.

Then some rap song about someone called the "Prime Minister" -- for a rap song, it wasn't half bad, production wise.  About a CB outlaw with a water cooled linear or something.  When that was done, there was just dead air.

Maybe this sort of thing goes on on the 40 meter band and I just haven't encountered it before.

Many thanks for the info, Glimmer Twin, it sounded like jamming this time. Maybe the mystery is now solved.

I wasn't aware of Cuba's jamming techniques.... that's good to know.

I logged them on 6/6 and 6/8, weak but somewhat readable (though I don't understand the language) on 11650 khz at 0440 UTC and 0550 UTC.

Heard several ID's, sung jingles with a guy singing "Radio Darbanga, Radio Darbanga" -- it sounded like there was an 'r' in there, even though there there isn't.  Each time I heard the jingles two or three times.

Shortwave Broadcast / Re: Greek State Broadcaster ERT To Close
« on: June 13, 2013, 1835 UTC »
Wow, that's too bad they're off the air.

I used to listen to the Voice Of Greece programs during the early afternoons when nothing else seemed to be on the Shortwaves.  Great music.

Many thanks for the info, Token.  It's very helpful.  I used to just ignore the CODARs when tuning the bands, now I log them down (if I can tell them apart).  Mainly what the frequency range is, and how many of them I think I'm hearing...

I with there were a list of them somewhere.  I tried entering various frequencies on the FCC database, came up with nothing.... :-(

I remember hearing the Waltzing Matilda IS and the kookaburra when tuning in R. Australia for "Countdown" and "Soundabout", religiously on 5995 and 9580, back in the 80's.

They still put in a powerful signal here in the NW at night, on several frequencies, 13630, 9660, 7410, and 11945.  Last night it was Rugby League football. The night before it was Grandstand AFL... A bit difficult to follow when you don't know the game.

R. Australia, R. Havana and R. New Zealand are the main English broadcasts I can hear anymore on SW (aside from the U.S. religious domestic stations).

I heard Firedrake again last night (6/9 UTC) on 13790 khz, 0655z.  Looks like it may have been used to jam Radio Free Asia.

699
Tuned through the 25 meter band, heard the data pulses again, on top of a carrier.

This time they were on 11930 khz, and I could just barely hear some audio way in back of them, sounded like a woman, and the pace and tone was non-English, poss. Asian -- but because the audio was unreadable, I'm just making a complete guess here, from the tones of the voice. 

I'm wondering if this isn't some sort of jammer.

Were still on the frequency during recheck at 0641z, audio was a tiny bit stronger behind the pulses, still unreadable.

Looking at the SW schedules, nothing is usually scheduled here in this time slot that would be jammable. The only thing I can find scheduled is R. Belarus.

The data pulses didn't really sound like LINK-11, as I noted in my previous post on this sound.  Unless there's an 'idle' LINK sound, like when RTTY is sort of idling, it just puts out blips....  but I don't know enough about sounds to venture a guess.

I wouldn't knock the fact you're using 'cheap portables' too much.  A lot can still be heard with inexpensive radios.  If your digital radio (does it have a model #?) has SSB, it's probably adequate for SWLing (the DX-350 is better used for bandscanning, and MW DXing / listening).

All I use is digital portables, and I've logged a lot of stations with them.  Here in the NW you can generally use more wire with digital portable SW radios than in other places, because our signal levels aren't as strong as they are back East where a wire can easily overload a portable radio's RF section.  You might try adding some extra wire to the SSB radio's antenna jack (if it has one) and see if you get better SW reception.  Try 30 or 40 ft of wire and see if that helps.  I once had a 70 ft wire and it didn't overload my digital portables.

As for what you can expect to hear, you'll probably hear a lot more foreign language SW broadcasts than English language broadcasts here in the NW US.  I receive a lot more Spanish broadcasts and Asian language stations than I do English ones.  

As for SW broadcasts, late evenings you can hear Cuba and Brazil (Cuba in English on 6010 and several other frequencies, Brazil in Portuguese on 6180 and 11780 khz).  Australia and New Zealand have strong signals on the 25 meter band (11945 khz for R. Australia and 11725 khz for RNZI) and the 21 meter band (13630 for R. Australia).  Radio Rebelde (Cuba) broadcasts in Spanish on 5025 khz.  China Radio International has a couple broadcasts in English that come in pretty well at night, as does North Korea.

When propagation is working right you can hear a lot of foreign language stations from Japan, China, SE Asia and South Asia on 41 meters and 31 meters in the early morning hours.

If you want to listen to the ham bands, the 20 meter band (14000-14350) and 17 meter bands (18068-18168) have a lot of activity in the late afternoon and early evening.  40 meters (7000 - 7300 khz) has a lot of activity during the night and early morning hours. Sometimes during the early morning you can hear the Indonesian ham pirates talking in Indonesian (and sometimes chanting) just below 7000 khz, or in the low reaches of the 40 meter ham band.

80 meters I've found more or less boring, and the higher ham bands (15, 12, 10 meters) are usually more or less dead.

I'm not that into utility or numbers listening, so the others here will have more to say about it than I can.

I've found the SW station lists on www.eibispace.de and www.short-wave.info very useful because those two sites are quite extensive when it comes to listing foreign language broadcasts (EiBi also has some of the main utility weather broadcasts listed) -- and most of what I hear seems to be in Spanish, Portuguese, or some Asian or African language.

I write everything down, using a spiral ring notebook.  I go through maybe 3-4 of them a year.

Upper left hand corner, I write the date in UTC, and day (local day, i.e. "Thurs eve.", even if UTC is actually Friday -- that way if I screw the date up, which can happen, I can go back and correct it more easily).  I'll also write down the model of the radio I'm using next to the top line of the sheet somewhere.

Down the page, to the left of the blue line I keep the time in UTC, right side of the line I jot the log notes -- khz, what I am hearing, SIO, etc.

I write a lot down, probably more detail than I need to, but it helps me later on if I have an UNID, to help figure out what station it may have been.  It also is useful because I don't make recordings of my loggings, so notes is all I've got to go by.

Later on I'll put the main loggings on the computer -- IDed stations and tentatives.  I have separate Excels for MW and SW.

Spy Numbers / Re: 6.7390 USB 2330 5 June 2013
« on: June 06, 2013, 0816 UTC »
Ah, yes, the 1980's, when the Cold War was still on. 

I remember tuning my DX-440 religiously to 6761 and 11239 (?) and hearing all sorts of "Skyking, Skyking, do not answer" stuff, and imagining some guy in a B-52 somewhere copying a bunch of numbers down.

Also a lot of 'skybird' traffic, routine comms.  It seemed I'd hear something on one of those two channels at least every 5 or ten minutes, some sort of transmission.  I don't know if those sorts of channels are as busy today, as I haven't monitored the military much since they changed everything in the early 90's.  Just lost most of my interest in it.

MW Loggings / Re: AM 530 kHz Morse Beacon RWE
« on: June 06, 2013, 0806 UTC »
That's a big 10-4! 
After all, I doubt it raises their electric bill by much.

Heard Firedrake on my '440 tonight in the 21 meter band -- 13790 khz, 0649 UTC when I tuned in. Was off during recheck at 0703.  Signal was SIO 444; was on top of an unreadable, faint signal.

MW Loggings / Re: AM 530 kHz Morse Beacon RWE
« on: June 05, 2013, 1939 UTC »
There's one in Western Montana on 520 khz or thereabouts, INE.  Sometimes I hear it, other times I don't.  Sometimes I get the RTTY from the NAVTEX station just below it.  Propagation seems a bit touch and go in that part of the MW spectrum.

You might want to try for INE sometime if the low band is in well.  I don't think there are too many other stations on that frequency.  If INE can make it 400 miles to my QTH without a loop, it might make it another 500 if you've got one.  It's been heard in Colorado, so apparently it does get out from time to time.
