Indoor antennas seldom work well. Even a poor improvised outdoor antenna
usually works better than something mounted indoors. A dipole in a L
configuration is likely quite mismatched. If at all possible try mounting
it as an inverted V, but it sounds like your L is necessitated due to the
size and shape of the room. Remember, a dipole radiates off the sides. If
even only temporarily, get it outside and up off the ground 15-20 ft and
broadside to WA or CA and see what happens. Not sure what a "RED LED SWR
bridge" is, sounds like some CB contraption that blinks when the SWR is
supposedly too high, wouldn't trust it as far as I could throw it. Put a
real meter on it. There shouldn't be any need for a Z or any other match
if the antenna is cut to the correct length and mounted correctly, away
from things that detune it, high enough (1/2 wave or better) off the
ground.

Its the default network node alias in a KPC3 tnc. We had the here with one
of our telpac nodes. It took us a while to track it down.

Great improvement. I'd prefer a slightly wider band to smooth some of the
noise in the obs and give a sense of the magnitude of the changes, but I'm
happy with it now.

Subject: [aprssig] Color code for fading stations?
Hi
What is the color code for stations that are about to removed?
I mean when a station beacon arrives it is displayed normal, after 5 minutes
the station color needs to change and so on as there is no new beacon.
Thanks in advance for the help

I am running a d700 in cross band.
Sounds very loud
Any way to adjust the cross band level ?

Gudday
I have a weather station sensor in the back yard.
It sent me 11.1 Degrees and 70 % humiidty - i know this cause i reset my
base unit and made it update.
What I need to do now is work out the code.
Looks like PWM ?
The values occur over and over again, but I have snipped just one. reading.
Any cyper gurus ?

Here are the original APRS definitions:
WHITE - Station with message capability
LIGHT GRAY - Station without message capability
LIGHT BLUE - A dead-reckoned station (more than 1 minute old)
DARK BLUE - Previous position
DARK GRAY - Station more than 80 minutes old
VIOLET - SOmeone else's OBJECT
YELLOW - Your OBJECT
GREEN - Digipeaters
BLUE - Weather stations
WHITE CIRCLE - (or box) around IGATES
ORANGE - A Mic-E (or KWD) set to SPECIAL
RED - An emergency station (Mic-E or KWD)
The reason for the 80 minute fade-to-gray for old stations is because that
is just under the shortest possible ORBIT time for any satellite. The ISS
for example returns in 90 minutes, so we want any old contacts that came in
via a satellite to be faded to gray before the next orbit. So this 80
minutes seemed like a good time frame for all of APRS. The original
fade-to-gray was 2 hours, but once we began using APRS via satellite, APRS
addendum version 1.1 shortend that to 80 minutes as above and suggested it
apply to all of APRS as a default.
Hope that helps.
Bob, WB4APR

I think you mean crossband repeater? Yes, it is somewhat overdriven.
I believe later models reduced it a bit. There is an internal capacitor
(surface mount) that can be replaced with a smaller value, but again, this
is brain surgery...
