[GreenKeys] Who Wants To Make A Sked For A QSO?

Hi Tony -

I'm curious about your trap dipole - especially the coverage you ended up
with and your trap design. I built one and installed it last fall. Mine
covers 80-40-30-20-15-10, and uses RG-58/u coaxial cable traps from the
design found at http://degood.org/coaxtrap

I tuned the traps individually before installation using an old Heathkit
grid-dip meter and my Icom 745 listening for the beat note (instead of a
counter). After tuning the traps and fixing them in place using Plasti-dip
coating, I then used the Icom VSWR meter to trim the wire lengths. I ended
up with this:
Band		Trap		2:1			3:1
80		n/a		3835-3880		3825-3895
40		7130		7124-7170		7115-7178
30		10140		10185-10262		10170-10275
20		14137		14010-14150		<14000 - 14167
15		21135		21040-21285		<21000-21370
10		28690		28680-29115		28400-29600

I should have tuned 80 a little higher, and 40 didn't come out exactly where
I wanted, but close enough. I wish the bandwidths were a bit greater. I hope
the traps don't catch fire when I get the BC-610 powered up.

How's your's look? Wonder if the design you used is any better in bandwidth
than my results...

Anyway, I'm almost ready to ask for a RTTY sked, but I'm not quite there
yet. Still having problems with the GRC-46 set (using the Kleinschmidts),
and haven't got the laptop configured with the Dovetron yet. The BC-610 with
M28 equipment is still a ways off.

BTW - will you be using computer or a real Teletype?

GE OMs;

I got my multi-band dipole up.

Works 80 - 60 - 40 - 30 - 17 - 15 - 12 - 10 meter bands.

All with a poor VSWR. I tried doing a little trimming, but nothing
happens. I used the ARRL antenna book to build it and it says right
there that trying to tune a multiband dipole is incredibly frustrating.

My transceiver has a transmatch in it and that handles the problem.

Anyway,

Who's active on the air?

I'd like to make a sked and see if I can work anyone on RTTY.

I'm available:

Mornings: Tue / Wed / Thur

Evenings: Tue / Thur / Fri / Sat / Sun

UE,
