Haven't built one of those in years... but yeah, they're compact and rugged.
But we're going to be camping by the car, so that's not an issue this trip.
I think I'll go with the steel or brass 1/4 wave whip. I think it'll be a
lot easier to set up if I carry my external frame pack than my daypack. We
used to make those brass whips all the time - you can stick them inside a
dried out weed and bury the radio in a ziplock bag for T-hunts. Within 1/2
wavelength or so of a chain-link fence for best effect. =]

Subject: Igate setup advice

Looking for any advice as to setup for a home based WinAPRS Igate for my
local area (Morgantown,WV) to try to spur some more local area activity.
I am using a cable modem type connection to the internet and want to
provide as much content as possible to the local users as there is a thin
amount of users so far.
Eventually this software setup will be transfered to our local 911 center
for permanent installation.

I remember reading a long time ago that Bob Bruninga wanted advanced
routing for aprs packets which would take a packet from me to a particular
city. It just dawned on me we have that now... we just need a *small*
tweak to the IGATE software (Winaprs, APRSS-A and UI-View)...
We assign each igate an alias and make it gate any packet which has it's
name in the path out to 2m.
For example, my town is Sumter. SMS is the airport designator. If my
local igate is programmed to respond to SMS anywhere in a packet, then a
packet such as :
kd4rdb>aprs v relay,wide,sms will always be gated out to 2m by my local
IGATE.
of course I could see more than one "destination" into my path....
kd4rdb>aprs v relay,wide,sms,atl,cae would pop out in Sumter SC, Atlanta,
and Columbia SC.
Each IGATE would not care about the position of it's name in the path, just
the fact that it's name was found in the path.
Workable? The present system requires the IGATE operator to manually list
stations which will be gated out to 2m. This gives the mobile user that
option.

Folks,
I totally agree with Bob on this issue, and for us it was a simple
solution.
One "can" (notch filter) "T'd" into the APRS line to suck out any energy at
144.850 MHz in Ken's case, worked wonders for us.

I would be interested in packages, such as the following.
1. 144.390, TX only with data interface, 1 Watt, 3v - 36v in
2. #1 with on board 1200 baud TNC.
3. #1 with power jack for 3V GPS supply.
4. #2 plus power jack for 3V GPS supply.
Package should be small and extremely durable.
