Been thinking long and hard about the next installment. So many tales, so much typing involved.

OK, "Herbie".

Herbie was some clueless git that we hired as a repair tech. Must have come from one of those useless schools that you see advertised on late night TV. You know, the ones where they give guys who want to study drafting the ridiculous notion that they will actually get to design stuff.

Other than draw what guys like me give them to draw.

Anyway.........Herbie.........as clueless as they come. The boss had the idea of getting Herbie interested in Ham radio, as this was still in the era when "ham radio" meant building something on your own. He figured that if Herbie had more practice on real electronics, that he might "get it". (He never did. At least not in his brief career with us.)

So, Herbie comes in one day, and announces how neat Ham radio is. Told us about all the guys he had been talking to. (I guess that he learned Morse code in the Boy Scouts. Do they still learn Morse code?) But I knew that he could not have even a Novice license. (Too dumb, combined with too little time since the Boss put the bug in his head.)

"Uh.........Herbie.........you know that you need to have a license to transmit in the ham bands?"
"Yeah."
"Well, how did you get a license so quick?"
"I didn't."
"So, you are transmitting without a license, right?"
"Yeah."
"And how then did you talk to anyone without having a proper call sign?"
"Oh, I just made some up."

That gives you an idea what we are dealing with here. But that is just background info. Along with he drive a Chevy Vega, and actually thought that it was a well-engineered car! (OK, not his fault the the morons at GM made their engineers take a neat idea that Alcoa had for an aluminum engine, and cost reduce it to total crap.)

Ok, background info on the wonderful world of telecom. The entire phone system works on either -48 V or -24 V DC. That is right: positive ground. (The reason that I heard had something to do with electrolysis. Easier to clean the negative battery posts and connections than all the ground connections...........)

So, you had to get used to making the red/hot lead the negative lead, and the black/ground lead the positive lead.

Unless...........of course...........if you are...........Herbie.

Herbie would swear that there was absolutely, positively, no way in hell that electrons would flow that way. Nope, ground had to be negative.

Herbie would take one of our lab supplies, during lunch hour, and futz with his horrible looking Ham radio monstrosities. Red to positive, black to negative. Yep, he took our connections down, and hooked them up his way.

And would leave it that way. Despite all of us cussing him out every day at about 1:03 PM. (Can you see where this is heading?)

So, one day, one of our most knowledgeable engineers was testing some gear that he had to take to the field. That afternoon. (OK, technically, it was the next day. But his plane left that afternoon.) Now, this engineer was not intimately familiar with Herbie. He knew who he was, and what a doofus he was, but was totally unaware about Herbie's recent conversion to illicit Ham radio operator. Or his "electrons can't flow that way" dogma.

So, after Herbie does hie Ham radio number, he hooks back up all this gear, but just had to make the red the positive............and the black the negative..........

The guy turns on his gear, and smoke went everywhere. This proved Herbie's convention that electrons won't flow the wrong way. Because it smoke when hooked up the Herbie way.

I would have fired him right then. Took a few more months.

No - not required for licensing. Some still learn it though; Luddites like the rest of us.

Jocko - Hilarious. For the wrong reaasons , of course, but hilarious...

Hey, I resemble that remark. No really -

OK , put it this way. I'm 37, an architect, and given a problem (any problem) I first reach for a pen, pencil, anything - and start scribbling. There's something that happens between my subconcious and marks on paper that is a lot better than either on its own merits. I can't quite explain it, but it all comes out in the wash.

Unfortunately , I very strongly suspect it has a lot to do with drafting being a prime consideration, and in that I was probably one of the last to get through 'boot camp' with a set of pens in hand, and treating the computer as the toy it really is. These days I set 'our' Part 2 students a task - no different to what I was facing only 9,10yrs ago - and the first response is always to push rectangles around in cad. None of them can sketch-to-scale or.. uh, that's like you EE types doing filter calcs without realising it, the whole 2-pi-omega thing etc.

Drives me up the wall.

And it leads to pics like the one I already posted (though that was down to the fabricator...)

Now, let me tell you about the time a contractor built the fold in a drawing...

Not only can't they draw, but they think that they can design. Gotta do the first before you can do the second!

Built the fold, eh.............hard to imagine, but I know it is true. Kinda reminds you of that Fawlty Towers episode where they knocked out a wall to install a new door.

All so true it's not funny, 'cept in extremis...

Building the fold is quite easy, if your are an idiot project manager, in receipt of 3rd generation A3 reductions from the site office of A1 hard copy issued drwgs , functionally illiterate and chose to ignore the 'DO NOT SCALE' rubrik...

Well I laughed. Wish I had a camera to hand...

Not that it matters, but the high school that I attended made everyone take "shop class" for 1/2 day, from 8th through 10th grade. Wood shop, metal shop, print shop, 'lectric shop. All were for one semester.

Except drafting. One whole year. Guess which one came useful once I hit university.

5 years after I got my 12WPM morse code, they got rid of the morse code requirement. Despite this, I wouldn't say the number of people getting into ham radio has exploded or anything.

When I first got into ham radio back in '92, people found it incredible that you could talk to someone on the other side of the world. I remember in '97, working at a Marconi site in Newfoundland, I managed to contact a guy in Australia. I had a crowd of kids around and was asking the Aussie their questions... "you have christmas in the middle of summer? wow!". Good times.

Nowadays we're all connected by the internet and having an across-the-globe conversation is so normal now. I'm having a chat with my brother in Korea on MSN as I'm typing this post.

I'm not sure that the appeal has gone. More likely, everything to do with the internet is just more in their faces than radio is. My experience is that kids are amazed that you can talk to somebody in Australia by not using a computer or cell phone.

It's also easier to explain to Mom and Dad why you need a new video card for your computer than why you need to put an antenna up in the back yard. Moms and Dads (and especially neighbors) seem far more tolerant of all kinds of illegal behavior on the internet compared to some kind of wire in the trees that might be an "eye sore" or affect property values.

Better your kid be a "demanding consumer" than actually understand something.

BFD. They used an Icom transceiver, that thousands of guys have, and hooked it up to a Yagi. Probably bought that as well.

OK, they could have wasted time playing Guitar Hero. So, they may be nerds, but not necessarily Nerd Heroes.

Kinda reminds me of the media hoopla over a certain girls basketball team that got crushed. Glad that is over with.

Did they use the ham bands or the actual ISS communications link?

The Paris Hiltons of Academia :read:

"Four wireless telecommunications students are building a radio station to contact the International Space"..

"Today, Mr. Rector, Paul, and I went out to Radioworld and purchased a transceiver. After much research, we decided to go with the ICOM Ic-V8000. For the cost, it has exactly what we need. On Friday, we're going to be integrating it into our setup, and doing all the necessary testing"

They "designed and built the antenna" though, according to some interviews, it was "over a year in the making and cost $3k so far." They also had to "build a back up". A NASA rep, or ARISS -- Amateur Radio for the International Space Station assigned mentor, was to check their work and make sure it was to spec.

"After doing some more research, we've decided on using a Hygain Two-Metre Oscar antenna. It has a circular polarization, which will help to cut through the atmospheric conditions. The antenna itself shouldn't be more than $250, and Skyward Towers Inc. has given us a quote to mount the antenna once we purchase it. We're hoping to get the antenna soon, stick it on a temporary tripod so that we can play with it and learn about it. Then come May, we'll go up there and mount it on the tower.

"Tomorrow, assuming all goes according to schedule, we should be starting the assembly of our primary antenna. We ended up deciding that the Hy-Gain OSCAR-style Yagi was the very best antenna to suit the needs of our project. While we assemble it, we're going to be taking some primary measurements for the antenna we're designing. Over the summer, we'll be building our antenna. We'll also be spending a considerable amount of time testing, re-testing, and re-re-testing both antennas"

"For the purposes of this project, we did a lot of research into what components (products) we should incorporate (buy) into our radio station. Ultimately, we decided on using the Yaesu G-5500 rotor based on it's(.. he did say his little sister did their power point and HTML) price, ease of use, and reliability."

"Now that we have been given the official go-ahead for NASA, the time has come to start getting the word out to everybody about our project. Today, we put on a small presentation for Humber's media outlets. Representitives from Humber's marketing department, Humber Life, Humber Et Cetra, and the Humber Student Federation came and joined us in Screening Room B for out presentation this afternoon. In a nutshell, we explained all the work we've done so far, and how we would like some media coverage."

"Last Tuesday, our group put on a presentation for Mr. Clint Thomas, a reporter for the Canadian Press. Afterwards, we had a short Q&A session up on the roof. He wrote up an amazing article, and put together a great video!

I was at work on Saturday morning when my boss came up to me. He says(lil sis) to me, "I just heard about your project on 680 News in the car on my way here." I thought to myself, "Wow! I can't believe it! This is huge!"

"I did a little research after work, and it turns out that our story has been published all across Canada. A quick Google search showed me that this article has been published in newspapers from Lethbridge, Alberta to St. John's, Newfoundland, and a whole bunch of places in between. In addition to local papers, I also found our story up on the Macleans website, the CBC's website, Yahoo.ca, Canoe, and the Sympatico page.

Even now, I just saw a headline on Toronto's CP24 channel about us. Last night, I saw our headline on CTV Newsnet.

To be honest, I feel it's a little mind-blowing. We're just four students from Toronto. We're not doing this project for any sort of fame. We're doing it because we want to do something big and exciting."

... considering the university students of superior intellect who'd done the very same a few months prior enjoyed wide exposure and these guys made it a point to be media whores from the beginning, it really must have been a shock. That whole angle about how non of them have any telecommunications experience and were all just lowly college level dipshits was fresh, a real tear jerker that had me all broken up.

"Right now, it looks like the school doesn't want any students on the roof. The exception to this may be Gino, who runs Sky 1 Communications, a very fine satellite company"

"Gino Cunti
Cunti has a background in satellite communication systems and was working in the broadcasting industry when he decided to upgrade his education and wireless communication skills at Humber. Cunti, 34, is the president of Humber’s Telecom Club and holds an advanced broadcasting licence in amateur radio. He lives in Toronto"

"Of course, we've been busy for real lately. There's a whole bunch of new stuff going on. Exciting stuff!

For instance, we soldered the connectors to the control wires for our antenna's rotor. After all that was said and done, we were able to control the movement of our antenna from inside room N214. Here's a few pictures of us working on that."

Then there's an action picture where the posers are holding up an end of wire... it didn't look that heavy?

http://www.operationfirstcontact.com/blog/episode16.htm

"Also, we're in the process of implementing a new piece of equipment into our communication system, called a TNC (terminal node controller). This magic box (joke?) will allow us to exchange data packets back and forth with the space station. "

"I got an interesting email from Gino this morning. In it, a link to a press release from Canada's Telecommunications Hall of Fame. In short:

OTTAWA, ONTARIO--(Marketwire - Jan. 28, 2009) - Canada's Telecommunications Hall of Fame announced today that it will pay tribute to Humber College students Paul Je, Patrick Neelin, Gino Cunti, and Kevin Luong and their professor, Mark Rector for their innovative(what what??) NASA-approved satellite radiocommunication system to make voice radio contact with astronauts aboard the International Space Station. The
Hall of Fame honours will take place at the 2009 Telecom Laureate Awards at the Canadian Museum of Civilization, October 29, 2009."

"If you'll allow me to do so, I'd like to talk a little about the hall of fame. (hear yeee hear yee)

I can't speak on the behalf of my teammates, but I think that having an organization dedicated to honouring Canadian achievements is an amazing idea. I've had many conversations with first- and second-semester students here at Humber, and one of the things that I stress is that the telecommunications industry is one of the most bla bla bla... katrina..... bla bla.... 911.... terror.... new amarckin heroes. . "

"Canada's role in as(?) a pioneer in the telecommunications industry, I feel, is often over-shadowed or taken for granted. Without the efforts of people like Guglielmo Marconi(Tesla) and Reginald Fessenden(Tesla), the industry would be drastically different. If you do a little bit of research, you'll find (Tesla) a whole list of Canadian telecommunications advances (I just can't name you any). And yet, so many of these great feats (the feats so great that I can't name for they are beyond words) are taken for granted.

That's why I believe that Canada's Telecommunications Hall of Fame is so important. There are a lot of of brilliant Canadians who have helped to shape the industry. They have, quite literally, changed the world forever. You hear about sports players (athletes?) being inducted into their various halls of fame, but let me tell you this: the people that Canada's Telecommunications Hall of Fame pays tribute to are heroes, and they deserve to be treated as such. (...)

It's fortunate they were able to buy everything they needed or they'd never have had the time for all those interviews where they told of how they "designed" and built a radio station, of their very "own design", and how miraculous an achievement that was considering their college level handicap (according to their teacher), how "huge" it is, how innovative both they and their very "own design" are, and how they are pioneer heroes to be worshipped.

By that very measure the kid flipping your burger at macdonalds is God, for he designed the cow. He would also be smarter because it didn't cost him $30k + to get so full of shit. It seems the measure of scholastic genius is proportional to media gullibility, but where would we be without the managers of tomorrow.

A term project like this should not have even been accepted, unless they actually intended on designing the gear itself! This media push to market obvious posers only poisons those they pretend to inspire, blowing hot air into yet another bubble, one where education here is worth a damn. Bring us your plain, your ordinary, with their loans, and we'll forge you astronauts by proxy too, may the crumbling gears grind on.

How sick is it? Sick enough to make an international big deal out of this apparently, sick enough to award them as national heroes in the hall of shame. That's more than sick. In other news earlier today I saw our canadian president, mini me, discussing the ever looming and ever growing gaping void of skilled, highly educated talent, and how they'll have to put on a serious push to import more to fill that gap. Status quo, snafu.

So for the punchline, even that 'tard Herbie managed his own monstrosities, placing him firmly above a league of heroes today. Here's to you, "Herbie" :good: No doubt, he's teaching at a fine school.

I have a NA1SS QSL card in my collection, from an open house we ran with a bunch of schoolkids in '01 or '02. You don't need that much gear - we used an Icom IC-2000, a homemade 5-element quad and someone aiming the antenna by hand with help from satellite tracking software on their laptop.

What you *do* need, more than anything else, is etiquette and restraint. It's frustrating when you've formally arranged the contact through ARISS, you've got a group of kids waiting with questions, and you have some tool running 10x as much power as you trying to take over the conversation.

Anyway, I can't knock the school for putting a bunch of parts together to make the contact. I wouldn't expect college students to have the know-how to build a full RF/IF receiver with enough selectivity and frequency stability to pick out the ISS, or even design a 2 meter PA for that matter. What they *do* have is a group of students that are at least passionate to some degree about radio, who may now actually decide to learn these things.

Which is a good thing. I'm finding that most people with practical skills in RF design are far and few between, and they're all approaching retirement age.
