Folks,
I'm posting this to the list because it is easier than sending seventy-six
gazillion individual meggases to everyone who's asked. This year's crop of
papers fall into three broad categories -- operating, filters, and
equipment. No antennas yet.
Operating:
Bob White, WO3B -- Bob is going to tell us how to computerize our logkeeping
with commercial database software. I will be minor contributor contributor
to this one. Bob uses Paradox, and I use MS Access, for our station log
books. Commercial database software will easily store your station log, and
let you "farm" it selectively for awards and other purposes. Note, this is
not contest logging software.
Bob Gobrick, N0EB, and Chuck Adams, K5FO -- Keyers, keying and morse code.
Bob is writing what he calles the definitive paper on sending cw. Chuck
will contribute his personal expertise with cw and, as I understand it, give
us some demonstrations.
Preston Douglas, WJ2V -- Preston tackles a pupoual and often controversial
topic -- how to be sure you're on the same frequency as the other guy. Zero
beat is the name and the concept. An interesting paper, and a presentation
that will include demonstrations.
Filters:
We've got every stage of the radio covered here -- some presentations you
definitely Do Not Want to Miss.
Mike Perry, PA3ASC -- An old friend from my days as PA3AIC, Mike will show
us how to design and build double tuned bandpass filters with components
from Mouser. Mike clearly explains the factors affecting filter and
performance. He includes a Basic computer program you can use to do your
own designs.
Bill Carver, W7AAZ -- Many of our QRP rigs use ladder type crystal filters,
and we all express wonder at how well these little four pole filters
perform. Well, how about 16 poles? Oh yes, 16 of them guys. A really high
quality SSB filter. Bill is one of our hobby's experts in multi-pole
ladder filter design, and he will tell us how to do it with inwexpensive
crystals.
The Reverend George Dobbs, G3RJV -- This year George tackles the back end of
the radio -- the output filter. He's put together a paper on practical
output filter design, including real world component selection information.
Do you suppose there is any reason why two of the three filter papers are
from Europe?
Equipment:
Dave Benson, NN1G -- Dave is going to stop designing radios long enough to
explain Direct Digital Synthesis to us. He will show us how DDSs are
designed using one of Steve Weber's DDS VFOs as an example.
Other papers on the horizon. I have promises of papers from a couple of
other authors but have not seen anything from them lately. I've given a
couple of them extensions, made possible because I got an early start this
year. If you've got an idea that just won't wait, talk to me about it. I
might be able to fit you in.
Our very first seminar (maybe):
I'm trying to put together a seminar on computer based schemmatic drawing
and board layout software. I have one speaker and need at least two more.
There will likely be a small extra charge for this seminar.
If you use this schematic drawing and board layourt software at home and
think you'd like to demonstrate it to a small group, talk to me. I don't
want the high end commercial stuff -- none of us can afford it and even
fewer of us have access to it at work. I hope to have an LCD panel and a
laptop computer to support practical demonstration. I don't have a spot on
the schedule set aside for this yet.
See you all in Dayton.
