Sean - Congratulations on your Limited Multi effort! It is not bad for January.
You seem to be mainly pursuing hardware solutions. That is OK, but some simple
operating techniques can help as well as new and different hardware at less
Be on when the contest starts. Activity is never higher.
You realize that CW is important, so be sure to have that capability next time
around. With a 10dB to 20dB advantage over SSB, it really pays off. If you call
a station and get no answer, often they can make out your CW when you call
again. If you hear some weak stations on SSB that you can’t make out, call on
CW, often you can make the QSO that way. With the recent influx of HF operators
to 6M, listening in the 50.90 to 50.100 CW portion of the band will often yield
QSOes that are not available in the SSB portion of the band. Related to this, I
keep PDF files of all my rigs on my cell phone so I can refer to them during
the contest if I have problems with the rig. This may have helped when you were
trying to figure out how to send CW with the mic buttons.
Pass stations from band to band. It sounds like you did this, but there are
some ways to make this more efficient. Pass to 432 first. That way if you lose
track of each other station you will make the high point QSOes first. Then to
222MHz if they have it, and then to 50MHz and two, depending on where you
started. Make it a point to work everyone on frequency before you QSY if you
can. Be prepared to QSY multiple stations at once. Tell people to meet you back
on two if you lose each other. Know who has what bands. A logging program can
help with this.
Use a logging program. It really helps in a lot of ways. You can track who you
have worked on which bands. Try not to let a station go until you have worked
them on all possible band combinations. The logging program can key the rig
with both voice and CW. That will reduce fatigue. RoverLog, N1MM+, and VHFlog
are all good programs with slightly different features. Interfacing the rig to
the logging program will prevent mistakes in not logging the correct band. If
you have two operating positions, it is possible to network two different
computers at two different operating positions. This helps in passing stations
from one band to another. N1MM+ can be used in conjunction with the cluster to
generate band maps of needed QSOes and mults. Plus, with a logging program,
there are no problems trying to read that other guy’s hand writing when you
prepare the log for submittal.
Use assistance. Follow the rovers on APRS and your favorite clusters. Look for
6M openings on DXMAPs. Trade information with other ops on the air. It is
straight forward to set up logging programs to identify who is on what band
from a cluster. Some rovers will text when they get to a new grid, try to get
on their text list or twitter. If a rover will give you a cell phone number you
can text or call the rover. But try not to abuse this as rovers get pretty
busy. Helmet fires are common among rover operators.
Keep track of the rovers in your area and try to work them on all of the band
combinations they have. Most rovers put out schedules of when they will be
where. Print this out and post it by your station. When you work a rover, ask
them when they will be in the next grid. About that time, point in that
direction and call CQ. That way, the rover will hear you when they get to the
new grid and you will get into his log early and not have to worry about
working him before he leaves the grid. Plus, you may work other stations in
that direction while waiting for the rover to show up. Offer to buy your
friendly local rover a beer when you see him.
Know who will be on the air from your area and what bands they will be on. As
propagation changes throughout the day, if you can’t work them when you try,
try again later. If there is local VHF group or e-mail reflector, join it. When
you go to a hamfest or swap meet, seek out other VHF operators. Ask their
advice. Tell them your plans. Return the favor when people ask you for advice.
Try to go to one of the major VHF conferences and network with other VHF ops
once every few years. Offer to give a talk on VHF contesting to your local
club. May is a good time as it is just before the Es season. Know who you can
work easily and who you will struggle to work. Radio Mobile online is good for
that as is the section on VHF propagation in the ARRL Antenna Book. You may be
surprised at who you can work that you think you can’t and who you can’t work
that you think you can.
Keep your butt in the chair. In the early morning hours when things are dead
try meteor scatter with WSJT.
Always use phonetics to eliminate confusion.
Turn the beam. Listen. Tune the band. Call CQ. Repeat. No amount of hardware
improvement can help as much as this.
Submit your log at the end of the contest. Study the soapbox write-ups to find
out what other people’s strategies are. Write your own soapbox entry so other
people can see what you did. Look at the log checking reports when they come
out to see if you can find hints in those to improve your contesting. Typos are
common. So are band entry errors. Both of those can be improved with attention
Practice helps a lot in contesting. Work all the VHF/UHF contests, including
the sprints. You get better the more you work at it. Don’t stop learning.
Now to hardware suggestions.
If you don’t use headphones get a good pair and use them at every position.
They help reduce outside distractions and noise. I think headphones add 6dB to
the signal to noise ratio over speakers. A headphone mounted boom mic will keep
your hands free to do other things like logging, checking DX clusters, and
drinking coffee. Use a foot switch for PTT. You will be surprised at how much
these things help, and they are inexpensive to implement.
It is no secret that one of the keys to success in VHF contesting is to be loud
on two. Be loud on two. Most contacts are initiated on two and then moved to
other bands. So being loud on two leverages the other bands. From your station
description, I think you can get the best bang for your buck by going to a
longer 2M beam, say 15 ft long, and raising it high enough to clear the house
by 5 ft or more. Alternatively, you can get another M2 7 element Yagi and stack
it above the one you already have. The trees won’t hurt much until you get to
432MHz if they are not too close. The easiest and cheapest way to get more
height is with fence top rail, available from fencing companies, or a Rohn push
up mast. I am not sure exactly where your location is, but if you are not in a
high RF environment, and are not experiencing desense or intermod, I don’t
think a filter will help much. If you are getting interference between bands,
simple coaxial cable stub filters at both positions are a cost effective way of
solving that problem. If you are using short runs of LMR400 you probably don’t
really need a mast mounted preamp either, at least on two. 50 Watts on 2M is a
bit light, and used brick amplifiers in the 150 Watt range are pretty
inexpensive. That will give you 5dB gain, which is significant. Some bricks
include a preamp, which may or may not help. The 857 is a bit noisy on two and
a preamp may help, but if you are using LMR400, on 2M at least, you won’t get
much improvement, if any, by moving it to the antenna. If you are in a noisy
urban environment, a preamp might not help at all. Be loud on two. In improving
your contest station, give your first priority to what improves your
capabilities on two. That includes receiving as well as transmitting. It will
Similarly a brick amp for 432MHz will boost your signal on that band. They
aren’t as cheap or plentiful as the 144MHz bricks, but they are not
prohibitively expensive either. A 100 Watt brick will give you a 7dB
improvement over a bare 857. With LMR 400, the line loss is increased, so a
mast mounted preamp may help, but depending on the length of LMR400 you have, a
mast mounted preamp may not be worth the trouble.
Lots of SSB/CW ops on 222 can also work FM with the same rig and antenna that
they use for SSB/CW, so a good way to take advantage of that is to hook a
horizontally polarized antenna to your handie-talkie. You don’t need to spend a
bundle on an antenna; WA5VJB’s Cheap Yagis will get you 11dB of gain for less
than $20. You can build two, one vertical and one horizontal to get those long
haul FM QSOes with regular FM ops as well. You probably don’t need a preamp on
those bands either, especially if you stick with FM. In the long run, a 222MHz
transverter is a good idea. Used 222MHz bricks are harder to find, but worth
the effort. 222MHz SSB and CW stations are few, so if you get operational on
222MHz, you will be very popular. 222MHz is a great band.
I hope that this helps, sorry it is so long, but I didn’t have time make it
