General Radio Discussion / Bluegrass music on shortwave
« on: September 24, 2014, 0328 UTC »
Suppose someone were to play an entire bluegrass CD album some evening on 6930 kHz AM.  Would the listener likely listen to the entire thing?  How many listeners do you think it would draw?

General Radio Discussion / Avoiding the FCC
« on: September 13, 2014, 1937 UTC »
Just reading the SW pirate loggings on this board, and see a number of broadcasters who do this repeatedly.  How do they avoid being caught by the FCC and sent a NOUO?  They have ways of long-range direction finding (HFDF), so it wouldn't be as difficult as people think for the FCC to track them down.

General Radio Discussion / Long-Range direction finding
« on: September 12, 2014, 0224 UTC »
Here is a recent report of a couple of ham radio operators on the 40m band getting in trouble for not identifying on the air:

http://transition.fcc.gov/eb/AmateurActions/files/Kraje14_08_19_5521.html

But how do they pinpoint a location from so far away?  The letter mentions use of long-range direction finding techniques.  The FCC agent was in Maryland, and the two ham operators were in South Carolina and Delaware.

Equipment / Ham radio frequencies for short-distance QSO's?
« on: June 03, 2014, 1930 UTC »
Let's say a person lives in a western Detroit suburb (Livonia, Westland, Garden City, etc).  Would it be possible to talk to someone in Lansing using ham radio?  If so, what frequencies would work for that?  It seems like it's too far for 2M/440 to be effective, and too close for any HF communications to work; it would be within the skip zone.

SDR - Software Defined Radio / Sound card for SDR
« on: February 22, 2014, 1530 UTC »
Is this the right sound card to buy for use with an SDR?
http://www.newegg.com/Product/Product.aspx?Item=N82E16829102063

It has a 192-kHz sampling rate, which I understand to be the most important spec.

I have an Intel D915PCY motherboard with a 2.8GHz Pentium-4 and 4GB of PC4200 (533MHz) memory.
I am running Windows XP with SP3 on that computer.

General Radio Discussion / 18900 - 19020 kHz band
« on: February 12, 2014, 1500 UTC »
Based on the shortwave broadcast bands here:  http://en.wikipedia.org/wiki/Shortwave_radio#Frequency_allocations

The 15m band (18900 - 19020 kHz) is almost unused.  Would that be a good band for pirates to use?  How would the propagation compare with the usual 6900 kHz band that they use?

General Radio Discussion / Programming on pirate radio stations
« on: February 11, 2014, 1539 UTC »
When people broadcast with pirate radio stations, what kind of programming do they typically do?  For those who play music, do any of them ever choose to play bluegrass or Southern Gospel music?  If so, is that more typical of FM or SW pirates?

General Radio Discussion / Pirate broadcast modulation modes
« on: February 09, 2014, 2120 UTC »
On shortwave, I understand that pirates use both AM and SSB for their transmissions.  But why would they use SSB?  It is terrible for music, even with a receiver capable of decoding the signal.  They would also be limiting their audience, because although many people have shortwave receivers, they can only tune into AM transmissions due to the lack of a BFO.  So for those two reasons alone, you would think most pirates would use AM.

General Radio Discussion / Fixed Service radio frequencies
« on: February 08, 2014, 2348 UTC »
According to this frequency allocation plan:  http://www.w2aee.columbia.edu/fcc-bandplan.html

The frequencies most commonly used by pirate shortwave stations are in the Fixed Service.  What exactly does that mean, and what kinds of communications are supposed to be there?  Is it actually used anymore for such?

General Radio Discussion / Pirate shortwave broadcast on 6930
« on: February 08, 2014, 0043 UTC »
Suppose I was to use an amateur HF rig to make a 10-minute broadcast of music (bluegrass and Southern Gospel) on 6930 AM, assuming a clear frequency at the time.  Would anyone likely hear it?  If so, would they listen to the entire broadcast?

General Radio Discussion / Shortwave pirate stations
« on: January 27, 2014, 0034 UTC »
Are most pirate shortwave stations in the 6900 kHz band, just below the 40m amateur band?  Are there ever any in the 31m SW band (9400-9900 kHz) or other bands?  Is there something particularly special about 6900 kHz that makes it a favorite for pirates?  Which modulation modes do most of them use?

General Radio Discussion / FCC notice of unlicensed operation
« on: January 26, 2014, 1913 UTC »
In reference to this FCC page:  http://transition.fcc.gov/eb/FieldNotices/2003/DOC-322883A1.html

It says that the pirate radio operator has 10 days to respond that he has authorization to operate.  But we all know that he doesn't, so what is he supposed to do in those 10 days, other than shut his transmitter down?

And how did the FCC find out about the station, since there is no station in the area operating on 95.3 MHz?  And how much power was he actually using?

Equipment / Transmitting audio on Yaesu HF rig
« on: January 26, 2014, 1734 UTC »
Is it possible to hook up an audio source (such as an iPod) to transmit audio on a Yaesu HF rig?  How exactly is the microphone jack configured?
