Oh, it's useful all right - in the event of an emergency, when all other means of communications are down, hams everywhere will still have the ability, no matter what, to talk about how their bursitis is acting up again, how those rioters downtown have no respect for their elders, and how much noise is being made all over the band by these "new guys" who can't possibly be real hams because they didn't have to pass a code test.  In bare feet.  In the middle of winter.  Uphill.  BOTH ways!

Having lived in central Texas, where storm spotting is taken seriously, I got my start with "real" skywarn reports, formalized emergency net etiquette, etc.  Now here in South Carolina, I was amazed to hear what counted as a storm spotter's report, given during what was identified as a net: "Well, it was rainin' real good out here a little while ago, and the wind blew down a few sticks in the yard, but it looks like it's done now."  This from someone who had supposedly taken a storm spotting class a week or two earlier.  You'd be able to get better, more accurate information by sticking your finger in the air and guessing than to rely on these guys for accurate emergency traffic.

Of course, aside from issues of cell site saturation, the fact remains that most cell traffic these days (and probably regular landline voice service as well) is handled by the same data backbone that moves regular Internet traffic around.  Or at least that's what I was led to believe when I was working at Ericsson and doing satellite uplink services.  If that's the case, then a "kill switch" thrown in the interest of national security would have the potential ability to stop or impede normal communication routes as well as Internet data traffic.

Gosh, that basket sure has a lot of eggs in it...

I had Radio Ronin Shortwave, playing Inna Godda Da Vida, and wrapping up with a greeting to our men and women in uniform.  \

Unfortunately, I didn't get times or recording of it.

It's a shame I missed all of the important logging stuff; it was a great signal here - maybe S9 or so into upstate South Carolina.

48
Yeah - I never did figure out what it was.  Frequency was off just enough - and the music abstract enough - that by the time I was able to figure out that it _WAS_ de-tuned, it was already well into the transmission. 

I guess that's a good reason to at least start a show (and pepper it within the playlist) with a bit of voice, or at least music that everyone knows, so that they can tune it in properly and know that they've done so.  Wailing guitars and obscure jam sets are difficult to tune to, largely because you aren't sure just what they're supposed to sound like when you get them tuned properly.

49
6.925 USB  A little bit above the noise, and up-tuned slightly - more like 6.925.250 or so.  Trying to tune to de-flange the sound, but I think that might be the way it's supposed to sound.

02:05 (appx) - on after WEAK cleared the frequency, can't quite make out the music
02:20 - apparently off again - never caught an ID
02:23 - back again - guitars
02:28 - speech, but I'm not able to make it out.  Sounds like a sermon, rant, or the like.  Sounds like it's zeroing out at around 6.925.330 or so now
Someone's angry - not going to take this any longer
02:35 - computerized voice leading into music
02:54 - speech again - something about Jack Shit, no shit, deep shit, no shit Sherlock, etc.  Seems to be around 6.925.170 now
02:56 - heavy electric guitars
03:05 - off, perhaps?

50
6.925 USB

01:37 UTC tune-in to extended guitar solo
01:40 - WEAK ID
01:49 - WEAK ID
01:54 - WEAK ID over music
01:58 - WEAK ID with deep voice giving email address
01:59 - national anthem
02:00 - WEAK ID and off

02:01 - maybe a weak, whispery signal underneath the noise, but nowhere near as strong as the previous content was, so I assume it's from someone else

Fantastic signal - between S9 and +10 on the meter, sounds great.

In one of the organizations to which I belong, there is the most amazing variety of pets on leashes at events that stipulate "no pets allowed".  The key is that they are all registered as "assistance animals".  You'll be hard pressed to find an actual seeing-eye or hearing-ear dog among the bunch, but there are cats, ferrets, snakes, birds, chinchillas, iguanas, and just about every imaginable type of fur, fins, and fowl there, mostly there to supposedly provide forewarning of seizures, and help allay panic attacks.  Talk to any of the owners in private however, and better than 90% of them will admit that they just didn't want to leave their pets at home for two weeks.

A pet is just a pet, but if you fill out the right forms, it becomes a service animal; you can take it anywhere with you, and it's actually a punishable violation of a person's civil rights to ask them to leave a place of business because of it.  The food, medical expenses, toys, and accessories also become a tax write-off, apparently.

I'm still waiting for a "Mexican Radio" tribute show over top of them, myself...

HF Beacons / 5185 in Maryland
« on: June 06, 2010, 2241 UTC »
This weekend I happened to be at an event in Little Orleans in western Maryland.

I forgot the external antenna at home, but out in the sticks away from electrical noise I was still able to hear the 5185 dasher just using the built-in whip antenna, maybe 20 inches long.  Copy was pretty rough in among some heat lightning static on Friday night, but it was in there; probably would have been a lot better with a real antenna.

54
CORRECTION:  As they were preparing to begin fueling this afternoon, a scrub was called.  They will apparently be making another attempt on Monday night, May 24.

55
Unfortunately, the Friday night launch was scrubbed about four minutes prior to launch, due to (if I recall correctly) a problem receiving telemetry from the spacecraft.

Spaceflight Now is reporting that the new launch window will be 11:17 PM to 11:35 PM Eastern time on Sunday the 23rd.  You can also watch live streaming video and a dynamically refreshing update of the launch status on SpaceflightNow.com.

About the only thing I keep my (extra) license active for these days is to keep people from grousing about the legality of my data and video links.  Enough hams can't cope with the idea that someone one third their age is allowed to play with "their" radio waves, or just might actually know something about RF that it almost isn't worth even listening around the bands anymore, let alone transmitting.  If you can manage to find someone who doesn't go on about how you "can't be a REAL ham because...", then about all that's left for them to talk about is their medical problems.  Beyond that, it's "call, signal report (always an inaccurate 5x9), weather, 73".

Just last week, one of the local FM repeaters was all abuzz with people offering their valuable opinions on which coax a new ham should use to hook up his 2-meter ground plane.  One of the "experts" - I know he was an expert because he mentioned several times that he's been a ham for almost fifty years now - repeatedly told him that you didn't need to worry about coax line loss.  It was unimportant, he said, because as an example, he's got 10 or 12 dB loss on his antenna, and "you can't hardly even hear a twelve dB sound if you're tryin'".  Even so, he said that he just makes up for it by talking louder into the mic, and everyone can hear him just fine (his audio was clipping pretty badly, actually).  The saddest part was, NOBODY contradicted him; several even agreed wholeheartedly.

Other "wisdom" I have heard discussed on the radio recently:
  • RF radiation and ionizing radiation are the same thing (because they're both called "radiation", you know).
  • There's no difference between the different types of coax - it's all just price.
  • SWR doesn't matter with modern radios - they can pump full power into any kind of antenna (no mention of automatic power reduction when high SWR is encountered).
  • You've GOT to have an SWR of 1.1 or less in all cases, or you'll burn up your finals within minutes.
  • You can't use a computer and a radio together because they'll blow each other up.
  • You can't build your own antennas or radio gear, because the people who make commercial units have access to "special wire", materials, and "design computers" to make them work.
  • Regular horizontally-strung dipoles are non-directional (all cases, regardless of frequency or height above ground).
  • It's impossible to operate HF from a moving vehicle, because the motion will cancel out the longer wavelengths.
  • You can't polarize an FM signal (apparently, horizontal, vertical, RH and LH circular polarization are all just a bunch of hooey, despite demonstrable effect).
  • The one biggest thing that can make or break a hamfest is having enough electric scooter carts available for rent (out of all of the above, this is the one item I believe to be true).

Listening to the local repeaters can be hilarious at times, but it doesn't take long before it just becomes too depressing to bear anymore; my dual-band mobiles are most often used for listening to the local EMT dispatchers these days.

For what it's worth, I've got the morse weakly on my attic-loop wire antenna in between 5185's beeps.  It probably needs a recharge, as it's been running for more than a week.

Down for a little while between storms and ionosphere weirdness, but it's in there again now.

5185 went down for a recharge while the storms rolled through yesterday - should be back later this afternoon, with a newly-charged battery.

HF Beacons / 5185 further testing

For the next little while, the still-experimental 5185 dasher will be operating with a slightly different antenna configuration.  It's the same wire, in the same shape, but with a lot less stuff between the transmitter output and the "business end".  Lower line loss will hopefully yield a better signal.
