RINO News:
Odilon Ferreira in Brazil seems to be the only person I could find with a
pair of Rinos. He wrote a product review on the WEB. He is not an APRS
person. I have paraphrased his report from some initial tests today.:
- The ID/Symbol/Position are sent to another Rino only when PTT released
- Location may only be sent once every 10 seconds [i thought it was 30]
- The maximum distance is less than 3 Km in urban area
- There is no option to automatically send the position. [PTT only]
- The position is sent to all Rinos configured to the same frequency.
- Rino doesn't have Simulation Mode. So,[testing inside is hard]
- It is possible to send Waypoints to another Rino, but it is not an
automatic procedure. It is necessary to press many buttons in both
devices to send/receive Waypoints.
Results I specifically asked for:
* The Position is received between 3 to 8 seconds after I release PTT
* Unfortunately nothing is shown in NMEA or in TXT Garmin protocol while
the position is sent. The NMEA log file is attached to you.
* Rino doesn't allow to hear the modem sound when "Monitor" is selected.
1) Good news to APRS is the apparent random 3 to 8 second delay after
sending a POLL and the small print in the manual that says that a POLL
only polls on the first 4 characters of the name. Thus if all users at
ONE event use the same first 4 charactetrs of their 10 character name,
then one poll will update for EVERYONE! If these are at 9600 baud, a
posit takes less than 0.1 seconds, then I think randomly (using the aloha
criteria) we could get DOZENS on the same channel in the same area.
2) So APRS users should chose a name like APRSwb4apr and we will have ths
software strip off the leading "APRS" when converting to APRS network.
3) Now I will ask him ifthe other RINO shows up in the WAYPOINT list.
Attached is his zipped CAPTURE FILE of the NMEA coming out of the RINO...

Subject: IRLP on APRS!
From: Bob Bruninga <bruninga@usna.edu>

X-Message-Number: 13
Just like ECHO link, there is now an APRS interface to IRLP.
This causes your IRLP node to put out a local OBJECT packet on 144.39 that
shows up on the front panel of your Kenwoods whenever it changes state.
It shows the node NUMBER, and FREQUENCY and STATE.. but because it is an
object, your radio also displays DIRECTION and DISTANCE. That's all you
need!
I was driving 2 hours to a remote area (Camp in th eCactoctin Mountains)
to give and APRS/Ham radio demo/talk to 200 BMW Motorcyclists at a
mountain retreat. I had no time to prepare, and so wished I had
remembered to look to see if there were any IRLP nodes nearby.
Then UNBELIVEABLEY, as I was driving along, up popped on my Kenwood:
IRLP7070
Available
146.895
And I clicked OK and the D700 indicated it was 30 miles north of me... and
I was going north! To make a long story short, it was perfect and what I
have been wanting from IRLP and ECHOlink for years. TUrns out the guy who
wrote the interface was on the same repeater. It is just some code you
load into your linux IRLP box and it does the job.
I contacted him, and he sent me this file that tells all about it.
By tomorrw, I hope to have a link to this text. But for now, I will
insert "some of it" here...
APRSBT
APRS Beacon generator.
Do you want your node to be displayed on local APRS screens in your area?
.... Using only a TNC and VHF radio you can [add this feature to your
IRLP node...]
This program script generates a text APRS packet that is sent via a TNC.
Set up on the APRS VHF frequency of 144.390 Mhz, it allows APRS users to
watch and monitor the activity of your IRLP node. When not connected an
APRS packet containing the IRLP Node's Latitude and Longitude, Frequency
and offset, and NODE AVAILABLE statement is transmitted every 30 minutes.
When connected to another node or reflector it will transmit the IRLP node
number, Latitude/Longitude and Node Number that you are connected to, and
Frequency and offset of your station. Utilizing an APRS formated text,
your callsign is transmitted in the raw packet but only the Node number is
displayed on the APRS screen as the APRS object. This allows the APRS
user to view node numbers directly on their maps but have a legal id of
the packet.
The Script runs as repeater and is a simple looping program that sends the
information out a serial port to a TNC. Installation requires the user to
open the script (using pico -w) and replace the parameters for the
aprs_node (node number), aprs_latlong,(latitude and longitude of node),
aprsrpt (node frequency and offset), and aprscom (serial port used by your
computer to TNC connection). Once these values are inserted a few lines
are added to the rc.irlp script to initialize the serial ports for use and
to start the script in the background.
A note about serial ports. The equivalent for windows follows:
Com1 in windows = /dev/ttyS0 in linux
Com2 in windows = /dev/ttyS1 in linux
(The UPPER CASE "S" is required)
Setup of the TNC parameters requires the user to access the TNC via a com
program prior to hooking it up to the IRLP system to ensure it has the
appropriate APRS parameters. The TNC must be in converse mode for proper
operation and will be commanded into the converse mode when the program
starts. The parameters running on a MFJ TNC2 at IRLP node 4234 are:
echo off
BE E 0
HEA off
mycall WA0OJS-1
headerln off
mstamp off
monitor off
unproto APRS via WIDE
conmode conv
conok off
digi off
conv
The script will send a "conv" command when booted so if your tnc is in a
power on reset state it will put in in the conv mode.
SETUP of SCRIPT
I have set up an aprsbeacon directory within the custom directory for the
file. Copy the "aprsbt" file to the /home/irlp/custom/aprsbeacon
directory. As "ROOT" open rc.irlp with "pico -w" and place the following
at the end of the file (the following is for "com1"; substituting the
appropriate serial port address for ttyS0):
echo -n "Setting up serial ports "
/bin/setserial /dev/ttyS0 auto_irq skip_test autoconfig
/bin/stty -F /dev/ttyS0 9600
echo "done! "
echo -n "Starting aprsbt ..... "
/home/irlp/custom/aprsbeacon/aprsbt >&/dev/null 2>&1 &
echo "done!..."
You will probably need to change the ownership of the serial port so that
user repeater can access it. This is done by logging on as root and
typing "chown repeater /dev/ttyS0 "
Save this file and open /home/irlp/custom/aprsbeacon/aprsbt with pico -w
(as repeater) and edit the following lines:
Replace your node number, latitude/longitude (IMPORTANT: LEAVE THE "L
AFTER THE LONGITUDE") and node frequency and offset and com port that your
TNC will be connected to:
aprsnode = "7070"
aprslatlong = "3900.00N/07600.00WL"
aprsrpt = "444.850+"
aprscom = "/dev/ttyS0"
Save the file and then as "root" in the custom directory type "./rc.irlp"
and the IRLP will restart. You should see your "IRLP node number and Node
Avail on an APRS screen. Your node number will be the object on the APRS
screen. Connect to a node or reflector and you should see the node number
that it is connected to. This will be retransmitted every 10 minutes
while you are connected. While disconnected it will send out a packet
every 30 minutes noting the Node Avail script.
I hope this give those wanting to share in the fun of IRLP and APRS the
ability to provide the information without installing a full blown APRS
software package on your IRLP node. The future of the two modes has much
to offer that is well beyond this package but for a simple start this
should work. Have fun.

Thanks for responding. Apparently the HT was too close and was desens'd.
I scrutinized the manual; the text description only talks about the squelch
function in describing CTCSS. However the figure shows that the sending
ctcss unit transmits the PL tone, also.
BTW: between HSV, AL and S.C. (via Atlanta) the squelch was never broken.

No clue about the message. But, perhaps it's a video hardware problem.
I know very little about APRSdos but I have had problems running DOS
software on newer hardware. Many video cards from the past 4-5 years
don't have a font that many DOS programs expect. The symptom you
describe sounds similar to what I've seen.
Here's what APRSdos looked like running under a DOS window on my Linux
system from a few years ago:
http://webaugur.com/bibliotheca/hamradio/aprsdos.jpeg
So, try this sometime when you've got a few minutes to waste. Grab the
fix8x14b.zip file from here:
http://www.bttr-software.de/fix8x14/
The included FIX8X14.TXT file explains how to use the various font
fixers on DOS and Windows.
In short, extract fix8x14.com and all it's related files to your APRSdos
directory. Create a batch file which contains this:
@echo off
fix8x14.com
aprs852.exe
fix8x14.com
replace the aprs852.exe line with whatever command you use to start
APRSdos. I have no clue what it's called these days. Save the batch
file as runaprs.bat or something you like in the APRSdos directory.
Then run the batch file from Windows Explorer as normal. Put it in Full
Screen mode, also. That's sometimes important when running DOS programs
on Windows.
