-
- After a bad experience with another company I thought I would relate a
- good experience
-
- I recently purchased and old Yaesu 301S QRP rig. I really am starting to
- appreciate it. .The case is in good shape but some screws are missing
- and some special fasteners on the top part of the case. Just for the
- heck of it I thought I would call the toll free number and see If I
- could get replacements. I was put through from the operator to parts
- immediately. I explained to the gentleman what I was looking for. He
- made sure he understood my request, took my name, address and phone
- number and said he would reference them in the computer and send them
- right out in the mail and enclose the bill... no charge on pre-payment..
- .sounded good, but I got worried about the cost.. didn't want to spend
- more than I paid for the radio. The gentleman said, the screws are about
- 5-10C each and the other parts not much more.. I decided to splurge.
-
- I really enjoyed the way I was treated and sure hope I get the parts.
-
- Have a good weekend.

- My advice? Keep the club intresting!!!
- Our club got in a rut. We appointed someone (Brant, take a bow) to
- find a special activity for each month we have a meeting. We have had
- many fine presentations, and our membership is becoming more
- intrested.
-
- Oh, and a good constitution never hurts. :)

- These units were, if they are the ones I am thinking of, pioneered in the
- tire industry and by the British police. The patents are held by Hugh's
- and they are a litle more complicated than has been so far indicated.
- They are also alterable via the readers. The British police used them to
- keep track of the football fans. They were given out as fan ID cards.
- The police at the games could use some sort of hand held reader to mark
- fighting fans without telling them. The next time the fans went to a
- game the detectors at the gate would notify the police that a trouble
- maker was entering and give them his name. I this in the journal
- "Science" from around June 1990. I'm not at all sure this is the right
- date.
- The tire industry used them to allow big trucking firms to keep a data
- base of tire histories. This way they would be able to tell how many
- times the tires had been retreaded, how many miles/months ago it had been
- last serviced, etc. While the readers are pretty expensive, I've heard
- that the actual IC's are around US$.05-.10
- In fact when I received my new computer a couple months ago there was the
- telltale sticker on one of the plastic baggiesthat came in one of the
- boxes. So it looks like Gateway 2000 uses the same technology to track
- their distribution.

- Please note, there is NO limitation on the amount of homebrew
- equipment that any ham can build. I don't know where Greg got this
- idea, but it is totally incorrect as stated above. The ONLY limitation
- on homebrew equipment I am aware of is in the construction of 10 (11)
- meter linear amps. Perhaps that is what Greg was thinking of?

- Thanks for the info, Richard. Do you know of any articles or published
- construction info? If a ham antenna can be made low-profile enough,
- radio thieves might ignore the car...not to mention carwashes.

- Thanks again -- Dan.

- Subject : Re: How does it work?
-
-
- I don't know for an absolute fact about the Card Key system
- mentioned in an earlier post, but it is probably a RF-actuated device in
- which the card reader illuminates the card with a radio frequency that
- may or may not change frequently, but serves to provide electric power to the
- identifier unit which is a small IC burried in the card along with a metalic
- trace which serves as an antenna. When the card is near the reader, the
- RF field is rectified to form DC which powers the little transmitter in the
- card. This transmitter probably starts sending a series of digital bursts
- containing the unique serial number of the card.
-
- If I am wrong, let's here from somebody who knows more about it.
-
- Oklahoma has a system called "Pikepass" in which one pays a turnpike
- toal by depositing money into an account. You, then, have a little
- palm-sized sealed device which fits on the driver's side windshield. When
- you drive through the toal booth area, you can just buzz right past the gate
- and a signal from a little dish mounted overhead wakes up your Pikepass and
- identifies your car, or rather, your account to the data base. When your
- account gets low, you get a note from the Turnpike Authority advising you
- that you need to feed the account, again, and you also see a sign which
- flashes "Low Balance" or something like that when you go through.
-
- Each month, you get a statement from the Turnpike Authority showing
- wheree you used the system and how much money is left.
-
-
- We have a Cardkey system at Oklahoma State University, but our cards
- are the magnetic stripe variety and don't appear to be anything special.
-
- This is all pretty far off the subject, but the techniques used to
- make some of these electronic identifiers work do involve radio and are good
- examples of cleaver design.
