- Subject: 1x1 Callsigns?
- To: info-hams@ucsd.edu
-
- The use of prefixes A0 and A1 would require an additional allocation
- by the ITU of blocks A0A-A0Z and A1A-A1Z to the United States.
- This is unlikely since it is a policy of the ITU not to allocate
- callsign blocks containing figures 0 and 1.
- There is an analogy:
- While Germany has DAA-DRZ, we will never have D0 or D1 callsigns,
- even thoughprefixes D2, D4 and D6 are in use (by other countries,
- though).
- So you can drop that idea. 1x1 callsignon the other hand are of course
- possible; it's entirely in the hands of the national authorities.
- So keep on pressing the FCC.

- Subject: 93 Quest-How to Mount A 2m Antenna?
- To: info-hams@ucsd.edu
-
- It all seemed so easy, there was so much open space up there for an
- antenna. I went out and bought an NMO mount and a 2-meter quarter-wave
- whip. Now I realize that I can't figure out how to get the headliner out to
- drill the hole.
-
- The minivan has a factory sunroof and a non-metallic(?) luggage rack. Even
- with the help of the shop manual, I can't figure out how to get the
- headliner out to drill the hole...there are 3" wide plastic retainers all
- around that seem remarkably immovable.
-
- There is inadequate room ("depth") above the dome light to mount the
- antenna there and still put the dome light back in. All windows except the
- windshield are openable, so thru-glass antennas are not usable except in
- front...anyway, I was hoping to avoid anything taller than a quarter wave.
-
- Has anyone successfully done this? How?

-
- Mike, I don't recall saying a lightning strike has an energy of 20J.
- What I said was that the quantity of electrical charge is usually
- about 20 *Coulombs*, and that a typical bolt flows 4000 Amperes. From
- that we can gather that the bolt lasts about 20/4000 of a second. The
- voltage is unknown, but in the millions of volts in the cloud to
- ground path. We can make the assumption that in most cases a lightning
- strike is a constant current source. So if we take a single driven
- ground rod as having a resistance of 230 ohms, we can assume that
- the power delivered to the rod in a stroke is I^2*R or 3.68E9 watts.
- Converting that to energy, we have 3.68E9*20/4000=18.4E6 watt-seconds,
- or 5.11 kW-hr. That's 18.396 Megajoules.

- HELP...
-
- Any Extra Class hams out there who can help me complete some endorsements
- for the 75M WAS (aka GERATOL) net? Out of over two dozen various endorsements
- available, I have whittled my list down to only a state or two for certain
- ones; that is, if I can work stations having the call sign formats following
- for the states listed, I can finish off these endorsements. The call sign
- formats and states needed are:
-
- Callsign #
- Format Example Needed States
-
- N 1x2 N2KK (2) AR, WV
-
- A 2x1 AB3C (2) HI, ND
-
- K 2x1 KC8X (1) WV
-
- W 2x1 WA4X (3) AL, ID, UT
-
-
- If any of you Extras out there having a call sign with the above format
- and state can schedule a quick contact with me (shouldn't take any more then
- a minute or so) in the 75M Extra Subband before it gets too noisy, pls send
- an email reply direct to me, and we'll work something out. Thanks in advance

- Subject: Lightning protection ...
- To: info-hams@ucsd.edu
-
- I've been following Gary Coffman's recent exchange about lightning.
-
- I understand that small radii (sharp points) discharge at lower voltages.
- Therefore,
- if an instant in time occurs when a surface has an even and high potential, then
- certainly the sharp point will be preferentially hit.
-
- However, part of lightning rod theory as I understand it, is that lightning
- will be LESS LIKELY to strike when properly installed lightning rods are
- present.
- This is precisely because the sharp points begin to discharge the surrounding
- area
- at relatively low voltages, making it less likely that the potential difference
- required for a mondo-strike will ever build up.
-
- I think this is the principal behind the multiple tiny sharp rods located along
- a braid across the ridge of a barn or home.
-
- Conjectures? Refutations? Anyone up for an experiment? ;-)

- There are many lists of Q codes; check ARRL publications at your local
- library or bookstore. The Radio Amateur's Handbook will have a list,
- there is one on the inside front cover of most ARRL logbooks, and other
- publications dedicated to the beginner in ham radio.
-
- But why waste your time listening? Do a little studying and you can
- be part of the fun! Talking with people all over the world is a lot
- of fun, much better than listening passively. 73 DE K6DDX

- Well, here in the Columbus area we have four PC based controllers. They are
- made by A/D Technologies of Atlanta. They have room for 1000 users and
- include voice mail and a bunch of other stuff. The first one cost $2000 but
- the price has gone up considerably. We have been "beta testers" for a lot of
- the software and the upgrades so we have had our share of problems. They are
- expensive, but they can do a lot, too!

- I do not have a copy of the ITU regs handy, but to quote chapter 3 page
- 7 of _The ARRL Operating Manual_ ... "US AMATUER CALL SIGNS...
- The International Telecommunication Union (ITU) radio regulations outline
- the basic principles used in forming amateur call signs. According to these
- regulations, an amateur call sign must consist of one or two letters (sometimes
- the first or second may be a number) as a prefix, followed by a number and
- then a suffix of not more than three letters. (...)"
-
- Hmmm...this says to me that S63NZ would be a legal call sign from Singapore,
- whereas S6NZ would not (the prefix is S6)...etc
