Upcoming SOTA Activation of W5N/BA-005 on 20 July

If you’re coming from sotawatch.org, welcome!

—Details—
Peak: W5N/BA-005 – 7284 [Socorro Peak]
Location: Socorro, NM, DM64mb
Time: 20 July 2013, 1700 UTC
Bands: anything I can manage. Likely 20m and up, and 2m
Mode: SSB preferred, but I want to try to muddle through some CW. I’ve never done CW without a computer (shame on me) so PSE QRS!

On 20 July, I plan to activate a nearby mountain for SOTA. This isn’t any regular mountain – the some parts of the road up to the peak is owned by EMRTC, or, simply speaking, its a bombing range. Therefore access is permit-only and this plan is tentative at the moment [edit — It’s a go!!]. However, at last night’s Socorro ham club meeting, I met a guy willing to be my escort, so I don’t get blown up, and to make sure I don’t steal anything, I suppose.

BA-005 is known as 7284 on the SOTA map, but the peak is commonly referred to as M-Mountain or Socorro Peak. A nearby peak which has a large, limestone M on it isn’t included in the database because it’s too near the taller peak.They only differ in elevation by about 60 feet.

This shorter peak is the home of the famous Elfego Baca Golf Shoot, where participants tee off at about 1500ft above and 2 miles awaythe hole. I think it’s a par 36 😀

Instead of golf, we’re going to shoot for some QSOs.

I’ll be using my new fangled End Fed Half Wave coupler and some conveniently placed towers. If those don’t work, then I’ll revert to some hamsticks. Stay tuned for more on the antenna project, and the summaryof the activation!

QRX

QRX for 3 weeks, to temporarily QTH: St. Vincent les Forts, Provence-Alpes – Cote D’ Azur, France. QRV as F/PC4T/P on 20 meter or 6 meter with SSB or CW with my FT817. Antenna is a small whip for 20m also a whip antenna for 6 meter. I have a 20 meter end fed wire, and I hope there is a tree nearby to attach my antenna. Have a nice summertime.

Encryption Is Already Legal, It’s the Intention That’s Not

Fresh from the Unless You’ve Been Living In a Cave, You’ve Heard of This department, there’s been much ado over the FCC Petition for Rulemaking seeking encryption for emergency communications.  I won’t go into the details of the petition as you can read that several places elsewhere.  Technically encryption on amateur radio bands is illegal.  However, in reality the FCC has been letting it happen for years and the ARRL has turned a blind eye to it.  D-STAR uses a proprietary vocoder that takes an analog voice signal and converts it into a data bitstream.  The algorithm isn’t publicly documented and you can’t decrypt it, unless you buy a proprietary chip.

Some may quote § 97.309 (4)(b) which basically says one can transmit an “unspecified digital code” as long as the digital code is not intended to obscure the meaning of the communication.  Presumably the people who created and use D-STAR don’t intend to obscure the meaning of the communication, so perhaps it is within the law.

So, say I create a new digital communication mode.  It features a compression algorithm and I just happen to XOR the data stream with a 10 million bit pseudorandom bitstream to randomize it so a long stream of zeros or ones won’t screw up a modulator.  I document the algorithm and the 10 million bit key on some corner of the Internet.  It’s technically publicly documented, but in practice no one will go to the trouble of attempting to build a decoder.  I’ve achieved encryption in a roundabout way.  Whether my intentions were to obscure the meaning of the communications or make a modulator-friendly bitstream is anyone’s guess.  But with the inaction over the D-STAR vocoder and the wording of § 97.309 (4)(b), intention rules the day.  So while this debate over the petition is being framed in a discussion of encryption, it’s really the intent to obscure communications that’s at the heart of this.

I don’t have a horse in this emcomm race, but I’m not in favor of allowing obscuring messaging.  If the FCC does allow it, others are going to want to use it for their noble causes, like preppers under the guise of “homeland security”.

(D-STAR is a registered trademark of Icom, Inc.)

Pizza Box Computer Screen Sunshade

Its always difficult to see a computer screen in bright daylight. Here in Florida, there are numerous pavilions with roofs over them and that helps a lot. Something extra is usually needed on a bright sunny day.  I had a pizza today and while I was waiting for it to come out of the oven at the Pizza shop, I asked the cook if I could buy a couple of extra boxes. I told her what they were for and she gladly gave them to me. The $4 tip didn’t hurt that situation I’m sure!

 

I'll make the next one prettier!

I’ll make the next one look prettier. 

I’m sure that I’m not the first one to come up with this idea. But here is my version of the Pizza Box Sunshade.

It is Relatively Dark Deep Inside the Sun Shade

The interior of the box is pretty dark. Note the clear packing tape holding the sunshade together.

 

Pizza Box Computer Sun Shade Back Side

I did this job by myself, so I didn’t have anyone to hold the box in place while I applied the tape.

Using ordinary paper staples was a mistake, they leave sharp places to stab your fingers with.

 

The Remnants of 3 Pizza Boxes Make Up This Sun Shade

Cheap and workable, the Sunshade should last a while. I’ll collect pizza boxes  to keep me supplied.

This pix was taken with a flash to show the interior of the Sun Shade

 

It took 3 Pizza boxes to make up this sunshade, and it was worth every bite of Pizza! 

I took this photo with a flash to show the interior of the sunshade.

Fair?

What means fair conditions? On 20 meter I heard no SSB at all, 5 CW stations, a few PSK31 and 1 JT65A. Oh boy. Maybe I take the FT817 with me to the South of France. It depends of how much space is left in the car. I do have a 20 meter whip antenna and a 6 meter whip. For CW I take the old Junker straight key. Good for 15 wpm. I cannot go faster with a straight key. I am spoiled by electronic keyers.
