- Since the "classic curly wire" seems to be the thing to catch the eye of the
- security folks, perhaps this is how I will be able to test just how well they
- can see through those lead lined film shields. One would be stupid to put
- something that even looked like a gun in there just to test them, but putting
- a coil corded microphone in there along with a few rolls of film might be the
- real test. If they consistently let it pass, and catch the coiled cord outside
- of the bag, then I will assume it is not the case that they can see inside the
- bag. I'd hope they'd recognize that the bag is blocking their view and ask
- to open it for a visual inspection (to make sure I'm not trying to slip in a
- gun by that method).

- Subject: How to use the incoming QSL bureau?
-
- Ok, I admit, I'm one of those people who doesn't have an
- envelope at the QSL bureau. How does the bureau work?
- I occasionally work DX on the HF bands, and would like to
- use incoming and outgoing QSL bureaus. I am an ARRL member,
- so that's not an issue.

- ----------------------------------------------------------------------------
- I know several active hams who do not QSL. One is K7SS. (The exception is
- his recent Guemes Island operation). When he is working them at the rate of
- 180 per hour in a contest, his rate and score would go down considerably if
- he had to explain to each one that he does not like to QSL.
- ----------------------------------------------------------------------------
-
- When I decided to be patriotic and get a WAS, I reckon I got a 95% return
- rate on cards by sending them with an SASE and enclosing a note mentioning
- that I was asking for the card for the WAS. It would never have occurred
- to me not to send an SASE. But K7SS (mentioned above) was one of the many
- who did reply - in fact, he sent me cards for two of the 50 states, as he
- operated two contests from different places. So he is a Good Guy in my
- books!
-
- However, what bugs me is *not* having to send SASEs, but the people who do
- not reply when you do send them an SASE. Not to get libellous here, but I
- need MD on 160, and W3LPL wouldn't reply to a card. KQ2M never replied
- to 3 requests for cards for his HD5X operation, and I still need that on
- 80m. I realize these are Big Contesting Types, but the least they could
- do is make up a simple note saying "sorry, I do not reply to QSLs", stick
- it in the SASE and send it back. Surely they have to open their mail to find
- out whether it contains a QSL card? What do these guys do with the SASEs?
- I have visions of them sitting in the near-dark (too mean to turn the light
- fully on), gleefully peeling the stamps off the SASEs, chuckling as they
- throw the QSL card on the meagre fire, then pulling out their sack full
- of unused 25c stamps and counting them again. Perhaps instead they sell
- the SASEs for 24.9c each to the neighbors.
-
- I think the policy is pretty straightforward. If you really want the guy's
- card, send him an SASE. If you don't care much whether or not you get a card
- back, send it postcard rate for 15c and then don't complain if you don't get
- one back. But if you get my card and an SASE and ignore it, you are a Mean
- Guy. My only revenge on such people is not to work them when I hear them
- in later contests - I suppose I secretly hope that one of them will be pushed
- into 11th place by one point (the one I didn't give them in the contest), and
- not get listed in the little QST Top Ten box. Hee hee, drool drool....

- I, too, need this information. Is this the correct group? In my case, I
- need a simple receiver that will tune in the BBC and Norweigan SW

- it will only be used for a finite number of stations.
-
- This receiver will be used in both Norway and the Seattle, WA area.
- Thanks loads, in advance.

- N4NMR talks about the cards he throws away at the W4 bureau that are for
- hams that don't want to receive cards. He asks why they don't tell the
- DX hams during the QSOs that they do not QSL.
-
- During a contest this is not easy. I know several active hams who do not
- QSL. One is K7SS. (The exception is his recent Guemes Island operation).
- When he is working them at the rate of 180 per hour in a contest, his rate
- and score would go down considerably if he had to explain to each one that
- he does not like to QSL.
-
- I know one thing that has cooled is interest in QSL cards is that here in
- the Pacific NW, we seem to have a pipeline to JA. After a contest, it
- seems that EVERY JA wants your card for EVERY QSO, no matter how many
- times he has worked you before.
-
- I try to QSL 100% to those who QSL me, and I keep my cards sorted. It
- is incredible to me how many cards I have for some JA hams....some will
- send 5 or 6 cards.
-
- One ham I know who is an active contester (N7TT) sends QSL cards for ALL
- of his DX contest contacts. At the end of a contest, he hires a neighbor
- kid to make out QSL cards for all the contacts, and sends them via the
- outgoing bureau. I know some hams have it all computerized and just
- print labels at the end of the contest.
-
- When I did my operation on Guemes Island, I worked 3,000 stations. I
- answered everyone who sent me an SASE. But I was amazed at how many
- QSLs I received with no SASE. I guess these guys who heard us working
- them at the rate of 2 a minute thought we were going to spend another
- few hundred dollars to address envelopes and pay postage to QSL
- everyone....or maybe they just weren't thinking. They are still in
- the drawer, and I may answer them via the QSL bureau...but I wonder how
- many of those guys actually keep envelopes at the bureau?

- Subject: Tuning dipoles and antennas.
-
- Tuning/resonating dipoles - well i never try resonating for lowest SWR.
- Remember, a low SWR doesnt mean anything as far as radiation efficiency
- or resonance are concerned (if you like, put a dummy load on the end of the
- coax - nice low SWR but it wont radiate very well :-)
-
- The thing to do is trim for RESONANCE - you measure this with your trusty
- dip oscillator. Get the dipole resonant at the frequency you want, then
- squirt some real RF up it. Dont worry about SWR. You'll put out a far better
- signal with a resonant antenna and 2:1 SWR than you will with a non-resonant
- antenna and a 1:1 SWR, all other things being equal.
- After all, the power 'reflected' by a non-perfect antenna match should be
- 're-reflected' back to the antenna by the PA tank circuit.
- If you have a solid-state PA or linear, then buy yourself an antenna matcher
- to keep it happy.
-
- Also, remember that the workable bandwidth of a dipole is related to the
- ratio of length to cross-section. Trying to get a good match across the
- whole of 3.5 to 4 MHz with a 'thin wire' dipole is just not possible.
-
- Making each 'half' out of several wires spaced a few inches apart will help
- here.
