I hope Jessie will forgive me for reposting his Email, but now that we
have a whole year
to plan for the next field day maybe now is the time to do this.

Subject: QRP FD
~ ~ ~ ~ ~
We used to run FD at 100w. Half a dozen years back, I talked the
group into trying a QRP FD, and we had mixed results. We switched back
and forth a few times, and ultimately found that our scores didn't change,
but, in general, we enjoyed the QRP FDs more -- especially once we added
PSK31. IMHO, operating FD QRP is actually a lot more fun b/c it's easier
to set up and tear down, easier to avoid QRMing your own operators, and,
if you traditionally use generators, it's also much quieter. Your
contacts are worth more, and we get a kick out of operating simple radios.
If you're considering a QRP FD, here are some further points and
suggestions for your club's consideration:
* Running QRP is a great way to reduce the QRM from your own
operators :).
* The solar contacts are great bonuses, and those of us with low
power radios often find ourselves running solar for most of the day. We
have a separate set of power plugs for solar, so anyone who wants to run
it can, and we try to each make at least five rather than just making five
as a group.
* We try to collectively earn a WAS. Not only does this create a
group goal (rather than competing for most contacts), it also gives folks
an incentive to move on from hard to make contacts and seek out other
contact opportunities.
* Bring outboard filters if you have 'em -- they can really make a
difference. Try different antenna directions and orientations -- it can
make a huge difference in background noise. Use of separate tx and rx
antennas can also offer a huge improvement in noise reduction, and adding
support for split tx/rx to your field radios can be a great club project!
Folks often think that a clear, but relatively quiet station won't hear a
QRP signal. Don't be so sure! It's S/N, not power, that makes the
difference :). The more stations you can hear, the more stations you can
potentially work!
* Don't forget the digital modes! PSK31 has been serving us well.
Don't forget VHF! A 6m opening can be a life changing experience! Don't
forget local contacts on 80m. You don't need to have a huge antenna and
you don't need to fight the QRN -- just make occasional passes to collect
locals. Also remember that VHF isn't just 2m FM and a mag-mount. If you
have a 6m or 2m SSB radio to spare, bring it, and scare up a beam or make
a simple quad -- your tech who would otherwise be trying to scrape up a
dozen 2m FM contacts with an HT will love you! Remember: horizontal
polarization!
* Be willing to work different bands. Some folks have pet bands that
they just won't leave even when they're not having much success. We've
also had folks actively avoid 20m SSB because it just seems like too much
of a bedlam. Again, good filters, directional antennas, and the RF Gain
knob can make a huge difference!
* Mentor less experienced ops -- a few simple practices can go a LONG
way towards making contacts more successful. Sometimes it's knowing how to
exchange numbers in other ways than just repeating 3A 3A (eg "one, two,
three alpha"), how to use attenuation, how to note when a station is clear
but too busy to hear you, move on, and try again later. These are great
points of education for members who may have never developed such skills
because they've never needed to.
* Leave the big shack radios in the shack :). One of the things that
can make FD stressful is having to tear down the home station, pack it
into a "hostile" environment, pack it back, and then rebuild the shack.
Many of us have our shack radios and also have several "field" radios that
we might not otherwise consider for FD because they are lower power rigs.
If you're operating a QRP field day, you can leave the home shack intact,
and just bring your field radios which are also more accustomed to being
abused. Our FDs used to be something of a show of force, where folks
would seemingly bring every piece of radio equipment they owned. Now, we
try to do the opposite and typically pack complete stations in laptop and
camera bags. Having extra field rigs in your ranks can also be great for
newer members who a) may be more afraid to bring their nice base rigs into
the field, and b) often really appreciate the opportunity to operate other
kinds of radios.
* With smaller, low power field radios, it's much easier to pack for
camping as well as operating. Small radios, batteries, solar chargers,
and headphones all around makes for a nice break from the loud, sprawling
technological complexities we usually live with at home, and just getting
out of town can be a real treat.
* A QRP FD is a great opportunity to make contacts with hand-made
radios. Building a qrp kit radio and making five solar contacts with it
makes a fabulous sub-activity.
Remember, FD doesn't need to be exclusively about the number of
contacts. When we tell our war stories afterwards, it's the more
challenging or interesting contacts that we brag about!
ntacts that we brag about!
