Huh? A "pre-tuned dupl
The general answer to the question is yes, you just need a program that
will copy the input from the USB connected GPS to the serial port, make
sure you have the proper 3 wire line to the radio, the right comm port
settings (baud, etc.) and its a go. You might even be able to do it

I wouldn't take it that you were - this is a discussion list -
people discuss things - we ask questions - share thoughts and learn.
I started by reading most of the messages in the list archives -
there's lots of information about system operation,
Having read things back and forth, I have a question:
I'm not in ARES, RACES, or any other emergency group, but I was wondering
Why choose a world-wide, open-gateway, type of system to be an emergency
system?
The way D-Star gets things out other than local broadcast range is via
the gateway, and
That's my point. People will put these systems in. They will find
that there isn't a perfect match of system features to their needs.
People will say - "X" is a problem - or it would sure be nice if we
could do "Y"
Then the computer wizards will write come code and fix "X" or
add "Y" and things
Excellent Tony. Though I have heard the remote NCO in action I never really
thought through the logistics of how that lends a hand in a localized
communication emergency.

Identify who I am?
Well, Ed, I use the internet option for Yahoo groups and I have
noted that on every message I enter on every group I post to - it
clearly shows: "nj902 <[EMAIL PROTECTED]>" - so I didn't think there
was anybody who didn't have access to QRZ if they wanted to know who
I am.
For those of you who are trying to setup documentation on your web site for
setting up DD mode with the ID-1 and a gateway connected repeater, a new option
is available on the D-STAR Calculator for creating links.

Interesting viewpoint
(BTW, why do you never identify who you are?)
If you don't want anyone transiting your gateway, then it is really easy just
to stop the services on the gateway, or block the inbound ports.
But from the point of view of many of us and our Emergency Management Agencies,

Could a USA op please contact me re my qrz.com email? (good)
Would like to check the following;

Running a cable straight to the TX or RX radio would eliminate a
connection point - I do see a potential for ingress of foreign rf into
the repeater enclosure on the shield of the cable without the bulkhead
connector - perhaps a suitable ferrite choke or ground strap could be
added ?
I suspect
Nice synopsis, Nate.

Satoshi,
I've been trying to figure out for some time how to descramble the
slow speed data in the DV stream sent between DPlus and the DVDongle.
The information you provided in this message is the key!

No tone, all are welcome.
Blocking inbound traffic is very easy, just block the incoming ports. This can
be done in the router or the computer firewall.
But I just have to question the need for it. Just how many inbound connections
do you get? If you don't want anyone to connect repeaters to you, then drop

I agree with Ron. The loss is negligible. But transmitter noise or desense
(these are separate and distinct issues) could be a more significant problem
since the TR separation is usually 600 kHz, and may now be 400 kHz in Northern
California. Another poster indicated a major improvement by rep

This loss is about .11 db/ft, little more than RG58. If one used RG223 (double
shielded RG58) the loss would be about the same.
Going to RG214 loss would be .05 db/ft, an improvement.
All this is at 400 MHz.
At 400 MHz the .11db loss would be .63 watts from 25 watts. I don't think much
