K1SIG has operating as Limited Rover in the previous 2 September contests.
Time is a major factor, something we're fighting a lot. We do stop and
shoot, and the set up/take down time is a bit long. We're working on
improving that. Homemade 2el moxon on 6, M2 7el yagi on 2, DSE 9?el yagi on
222, and a 15el diamond yagi on 70cm. The most recent contest we had an
IC7000 @ 100W on6, an IC746 @ 100W on 2m, an HTX100 with one of the
ukranian transverters @ something like 5W on 222, and an FT790RII @ 25W on
The moxon is made of PVC pipe and some thin wire. It works really well, and
was pretty easy to build. I need to reinforce it a bit, we had some
problems both contests with my solder joints on the UHF connector not
holding. Next time out that'll be re-soldered and epoxied down.
In January we'll be doing a run and gun setup instead, the IC7000 and
HTX100/xvrtr to cover all 4 bands, and likely FM mobiles as well for the
top 3. We have loops for each band, and will have verticals for FM. January
is interesting because the mountaintops we operate from in New England are
all closed. We're fixing that by driving from NH to VT via MD.
Just watch your antenna height for bridges and trees and such. Clipping
such a thing will put you out of action.
You might want to go simple for your first time, but we didn't and it
didn't hurt us that much. You'll hit snags. Things won't go right. It'll
still be fun. You'll think you're insane. You'll know you're insane. It'll
be even more fun. The addiction will grow.
One thing we've started doing that really helps is to create a custom map
on Google Maps. We laid out the grid corners on it, and have started taking
notes on sites that work and don't (I probably should translate this to
something share-able...). We have stations that we like to work - big
stations that we know will always be there, like Dale AF1T - so that we can
both plan where to aim our beams and determine if we'll actually be
anywhere near anyone. Sites are marked as green (good), yellow (workable
but have issues of some sort), red (bad for one reason or other, which very
well might just be because there is a fixed station, like W2SZ, that lives
there every contest), or black (requires scouting before opinion is made).
I'm terrible at timely updates, but you can read of our first two rover
The 2 most recent posts are a year apart, and are the 2 september contests
we worked as K1SIG/R.
Good luck and 73,
Sean Waite, WA1TE
