Our RACES organization will be acquiring (Qty. 4) DR-135's in a few months
as we settle in to our new city hall and EOC, along with new 180ft tower. 2
of our new DR-135's will be dedicated to APRS, the other 2 for regular
packet on linked into our state network. I've never used this radio
before, and hope to have my hands on them soon. I understand the units do
not support node functions and such, so 2 of the units used as regular
packet nodes will be used with external KPC 9612's.
In general, is there anything I should be aware of when doing this? Do I
need to physically have to remove the TNC module or can I let it remain in
the radio and disable it for use with the external TNC, etc? I believe
there is a DB-9 connector on the rear of the radio...can this be used for
my connection to the external KPC, etc?

Well, Kee, what kinda TNC do you have? There should be a way to adjust the
audio output of it from a pot in ole ones to from the keyboard in modern
ones.
I specified this in my earlier message, so that you would still have the
radio with proper deviation (IF it was properly set at the factory a BIG
IF) for voice use.

Thanks for that info but from the way it sounds, it looks like a grounding
issue. Plus, I dont see anywhere to adjust the deviation. I took out the
int. tnc and put my kpc3 on the radio and everything seems to work fine.
Maybe I just got a bad tnc.
Oh well, guess I'll use the Kan for awhile.
Thanks everybody for their response.

Harold: You can download a manual for the EJ-41U TNC from
http://www.alinco.com/usa.html click on "On Line Manuals", then go to
bottom of listing to "Misc" then to EJ-41 Instruction Manual. This shows a
drawing of the EJ-41 unit & shows VR1: For the modulation level adjustment
of 9600bps TX data and VR2: For the modulation level adjustment of 1200bps
TX data. The instruction manual is quite complete. By the way it appears
that the unit does not have to be removed from the radio to use an external
TNC. Just do NOT activate the EJ-41. Hope this helps. 73 de KC8DRE Bill

How find digipeater in a specific region hundreds of miles away?
I would like to establish a path to a specific location in another area. How
can this be accomplished? Is there a listing of digipeaters that could be
used to create a path or is it empirical. I am new to APRS and am having
fun.
Another question that is somewhat related. What is the difference between
wide, wide and wide2-2? What is the difference between wide3-1 and wide3-3?
Is it bad to do a wide7-7?
Thanks

There is no difference between wide,wide and wide2-2, except that wide2-2
uses 7 bytes less data to accomplish the same thing as wide,wide. They both
will travel the same distance provided the digi's support WIDEn-n in your
area.
The difference between wide3-1 and wide3-3 is 2 hops. For wide3-1 the first
WIDEn-n digi will count the 1 down to zero. For wide3-3 the WIDEn-n digi's
will count the -3 down to -0 to accomplish the 3 hops. There is no
difference between the two in terms of the amount of data you transmit.
It is interesting to note that the difference between wide,wide,wide and
wide3-3 is 14 bytes of data reduction to accomplish the same task. The
WIDEn-n is simply a way to reduce the data on your transmission to free up
the 1200 baud channel.

Hi Kelly,
I have a document that will help you. It describes digipeating concepts in
very generic terms. Along the way, you can figure out the answers to your
questions. It is a 21k PDF. May I send it to you?

It depends on the existing digis in the area between your location and
there. The best bet may be to use http://www.findu.com to look for digis in
each area.

Most important first - You generally don't want to do a wide7-7. It'll
cause a lot of packets over a very wide area and make you unpopular.
What you're asking about is often referred to as wideN or wideN-N. It's an
adaptation of the ssid to allow more flexible routing. If you send via
relay,wide your packet must first be heard and repeated by a station
answering to relay or it will go nowhere even if it is heard by a station
answering to wide. WideN also usually implies that the digipeater has some
smarts about preventing duplicate packets. If you didn't have those smarts
available you could see the same digipeater echo the packet multiple times.
If we write it as WideX-Y the X represents the number of targeted hops and
the Y represents the number of remaining hops. Each time a digi repeats the
packet it subtracts 1 from the Y portion. So, in your example above the
Wide3-3 was heard direct (it has not been digipeated) and the Wide3-1 was
heard after two digis repeated it.
Back to your routing question - if you are trying to get to another
specific area you may want to include specific digi names in your path.
Remember that if you use "wide" the packet goes that far in every direction.
