General Radio Discussion / Re: Reuters article on shortwave

The internet is useful.
You can tell ops Pirate or otherwise how well you're hearing them in almost real time.
(tongue only halfway in cheek.)

General Radio Discussion / Re: Yahoo is tracking group members
« on: January 10, 2009, 1824 UTC »
Is Google doing this stuff, too? ???
Got off Yahoo, and the groups/e-mail not long after I heard about this awhile back.
Private groups spying on you are worse than the government, imo. (RIAA ring a bell?)

General Radio Discussion / Re: When there's nothing on the dial.....
« on: January 05, 2009, 0312 UTC »
I'm on a dial-up, so anything above 40 kbps chops up like Martin Yan doing a number on an onion. Or something like that..

An exciter works just fine for that.  :)
Compression is not the problem, most of the time. Over-modulation is the culprit.
Since most good transmitters have a line audio input, there's occasionally the temptation to boost the signal, just to make it louder. Just enough will do exactly that. Too much and you just get unintelligible crap. (Technically called "clipping".)
Amateur equipment usually doesn't have a VU meter to monitor that stuff, so it's just a matter of tweaking the volume on your input source.
It's trial and error, but part of what makes the hobby so damn much fun.

http://74.55.244.98:6955 RJI archive stream, mostly WBCQ stuff.
This is a futile attempt to call a truce with the rodents, so I can save my Monkey Boy butt from eternal damnation.
I must go and check my tire pressure now........ ::)

I always had trouble hearing them @ the old frequency.
JJY would come in a lot stronger on most evenings.

North American Shortwave Pirate / Re: Undercover Radio 6925 USB 2225z
« on: January 01, 2009, 0809 UTC »
An S2 here for Dr Benway.
He mentioned listeners in Colorado, so maybe his van is parked a little closer to me. ;)
Heard his first slob-net caller better than he did, so maybe not.

General Radio Discussion / Re: 2009(!?) Fest Casting Call
« on: December 30, 2008, 0450 UTC »
Just wish I could make Winterfest next year.
Have to find someone who's willing to lug a reasonably nice, but exceedingly untidy New Mexico swl with them. :D
Oh yeah. That'd probably be Grayhound. ;)

Shortwave Broadcast / Re: Is DRM the next AM Stereo?
« on: December 29, 2008, 0251 UTC »
The availability of relatively cheap computers and internet access, doomed DRM from day one.
Winamp running at 32 kpbs/44kHz AAC+ runs well even on crappy dialups and can provide some really impressive audio, with a bit of eq. tweaking.
Better sound than DRM and a much larger range of listening choices.

Spy Numbers / Re: Homebrew numbers startions
« on: December 29, 2008, 0229 UTC »
I thought WBNY's coded broadcasts could be considered a home-brew number station.
If you go through with the plan, just make sure you remind everyone to check their tire pressure. ;)
