The most effective song and dance I did in front of a Jr High Skool class was tearing apart various cell phones, walkie talkies, computahs, and consumer electronics to demonstrate that they should not be afraid of such things. Unfortunately, the parents hated my guts when the kids starting practicing what I showed them. Learn by Destroying(tm). 2nd best was dragging in my collection of old cell phones including an IMTS control head, various bag phones, and an unbelievable brick like handset that's VERY heavy. I also brought an early Motorola tube type Breaky-Backy with wet cells inside. Some of the stuff still works. Nobody was interested in Morse Code until I mentioned that it could be used for "secret communications". That means that the parents and teachers couldn't understand what the kids were saying. Lots of interest (and potential problems) there. The problem with todays version of ham radio is that it's really boring. Nobody wants to talk to someone around the world, when they can pickup a POTS or cell phone and do it with much less effort and expense. With the demise of Heathkit, building radios is no longer a draw. The magic of radio is gone. So, show them what they can do with radio. Weather stations, APRS, satellite, construction, etc are a good start. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

The numbers of enthusiasts may drop, but those left will be more focussed and dedicated. The quantity is being replaced by quality. For every ten new hams who buy an off-the-shelf radio, play with it for a year or two, then lose interest, there is one in whom the spark is truly lit. Building is alive and well in the form of QRP. The satisfaction of operating a TX which is the product of your own efforts and ideas beats driving a commercial radio any day. (There is a mirror to all this in the model aircraft hobby. Many now begin by buying a top-dollar almost-ready-to-fly radio controlled plane. All you need is money. Little achievement, little reward, other than the transient buzz of flying the thing. Same effect - 90 percent drop out, ten percent go on to greater things: building and designing their own creations). Don't believe the prophets of doom who tell us that ham radio is dead. They're just pessimists and losers. Ignore them and move on. |

You can call CQ in a 10G contest off of a local 30 story building, or even better - a local rain cloud. The systems are normally built as transverters from kits. And learning is involved in construction as you figure out how to interface a 2m SSB rig to a transverter, and where you find mini hardline, and SMA relays for cheap. Using them teaches the user a lot about practical microwave propagation. Interested persons from the Midwest or those from anywhere else check out www.nlrs.org.

While the TCP protocol comes ready made, the spirit of ham radio is very alive in the way people coerce a pringles tube into doing these things. |

Unfortunately if they are properly made, they are illegal to use in the US and other places in the world. The EIRP limit in the US is 1W for portable/mobile and 4W for fixed (point to point use), a properly made Pringles antenna produces slightly over 4W with 100mW input. Here it's even worse, the EIRP limit is 100mW, so any gain antenna is technicaly illegal, though 5dbi ones they are sold here. It's become IMHO more like the spirit of modifiying CB rigs to transmit and receive in that little slice of radio spectrum between CB and the 10m ham band aka "freebanding" than the spirit of lawful, respectful ham radio.

Not for a Hams in the USA, with a Tech or higher License, on the Ham portion of the 2.4 Ghz band... We can use up to 1 Kw output power, not in a Pringles can, but with the appropriate Feedhorn, and an old 8 ft TVRO Dish, Moon bounce is a very real activity. It is the Tracking Hardware that gets expensive.... that and the 2.4 Ghz TWT's..... |

To someone new to the hobby, communicating with peoples on the other side of the planet is commonplace. Pickup a cell phone, dial, and talk. There's no magic in that. In the past, showing potential new hams how it works got an "amazing" reaction. These days, I get asked "what's all that noise"? It's no longer a technical hobby, but more like a "radio sport". It's no longer about building and refining a radio to the bleeding edge of the state of the art. It's now what you can do with a radio. Fortunately, there's plenty to do with a radio. I listed a few. There's plenty more (contesting, CW, boat anchors, xmitter hunts, microwave, field day, packet, meteor scatter, etc). Plenty to interest a Jr High Skool brat, but you have to show them first. I used to worry about overwhelming them. Not any more. I show them in everything I can find and let them find their own inspiration. Oddly, the local new hams seem to be coming from the 4-H Organization. The numbers of enthusiasts may drop, but those left will be more focussed and dedicated. The quantity is being replaced by quality. There was a surge of new hams wanting to use ham radio as a cheap cell phone. That didn't last, but it sure fattened the various club treasuries. I'm not sure those remaining are more dedicated. Most of the radio club members are 50 or more years old. There are younger members, that also tend to be very technical, but they're disappointed at the general lack of technical expertise of the older hams. Comments like "how do you expect to operate a software defined radio without any programming skills?" are common. I give at least one technical talk a year to the local clubs. I can tell by the audience's faces that only a few have a clue what I'm talking about. I passed out about 30 CD's with 4NEC2, EZNEC demo, and a zillion models at one meeting. I think perhaps 1 or 2 people tried it. Don't believe the prophets of doom who tell us that ham radio is dead. They're just pessimists and losers. Ignore them and move on. I like to think of myself of being part of the solution, rather than the prophet of doom and despair. Please ignore me and move on. -- # Jeff Liebermann 150 Felker St #D Santa Cruz CA 95060 # 831-336-2558 # http://802.11junk.com # http://www.LearnByDestroying.com AE6KS |

To someone new to the hobby, communicating with peoples on the other side of the planet is commonplace. Has been for years. Pickup a cell phone, dial, and talk. There's no magic in that. I remember making telephone calls to other countries when I was a little kid in the 60's. The Transatlantic cable was laid in the mid 19th century. People could talk a long way away then too. Worldwide communications pre-dates radio communications. It's a matter of infrastructure. some snippage I like to think of myself of being part of the solution, rather than the prophet of doom and despair. Please ignore me and move on. Not trying to bust your chops or anything, Jeff, but if you have no more magic in you for Ham radio, its going to be really hard being part of the solution. - 73 de Mike N3LI - |
