Graag wilde ik voor mijn SOTA activaties een portofoon hebben. Mijn keuze is gevallen op de Yaesu FT1XD. Deze portofoon heeft ook de mogelijkheid voor APRS. Instellen gaat als vogt:
– Houd de DISP button ingedukt om naar de settings te gaan.
– Scroll met de knop naar “9 APRS” and druk op ENT.
c. Goto “4 APRS MODEM”, hit ENT, use the knob to set to 1200 baud and then hit
the DISP button once to back out one level from the menu
d. Goto “8 APRS MUTE”, set to “ON” (this will allow you to not hear all the
1200baud AFSK packet sounds
e. Goto “9 APRS POPUP” and you might consider changing many of these to OFF
except MSG, GRP, BLN, ACK/REJ, etc. do avoid having the radio constantly
interupt the display with a remotely heard APRS station
f. Goto “10 APRS RINGER” and you might consider changing many of these to OFF
except MSG, GRP, BLN, ACK/REJ, TX BCN, TX MSG, etc. This is to avoid having
the radio constantly beep at you with a remotely heard APRS station
g. Goto “14 BEACON INTERVAL” and change to say 10min if you want to save more
battery life when NOT using SmartBeacon mode
h. Goto “15 BEACON STATS TX” and optionally consider turning “S.TXT” on and
setting the #1 field to what you want to say. Can be like “Walking around
with my new FT1″ or “In the Tundra.. send me a MSG”
i. Goto “16 BEACON TX” and set to ” AUTO” fo the radio to send beacons
when needed. Set to manual for best possible battery savings
j. Goto “20 GPS POWER” and set to “ON” (turn this OFF when you need to conserve
as much battery power as possible) – GPS can be used for both YSF and APRS
k. Goto “23 CALLSIGN(APRS)” and put in just your callsign and SSID. For me, I
would put in “KI6ZHD” and then in the last character space after the callsign
(“D” in this example), turn the knob once to get a “-“. At this point, you put
in your SSID. SSIDs and Symbols are helpful to tell remote systems what
kind of device you’re using and your status. For an HT, the recommended SSID
is “-7 : -7 walkie talkies, HT’s or other human portable”.
A good link of recommended SSIDs can be found here: http://www.aprs.org/aprs11/SSIDs.txt IMPORTANT NOTE: Both the SSIDs and symbols for APRS change over time as things change in the world. It's important that you should review these documents every so often to make sure you're up to date Once the SSID is selected, hit the DISP button to go back. This nagivation is a bit inconsistent with the reset of the ways to use the radio!
l. Goto “24 My POSITION” and set to ‘GPS”. You can also learn your position
from GPS and then save it into a memory slot. At this point, you can then
turn off the GPS to save battery power as long as you’re stationary
m. Goto “25 MY SYMBOL” and have it set to “/[” which is the HUMAN/PERSON icon.
You can also change this to other icons like a “Bicycle” when riding around,
“Tent” when camping, etc.
A good intro list of symbols can be found here: http://aprs.od5.org/symbols.htm NOTE: This isn't 100% up to date but shows a grapical view of the various icons. The official symbol list is here but it's just text: http://www.aprs.org/symbols/symbols-new.txt
n. Goto “26 POSITION COMMENT” and set it to something you prefer – This is part
of the MIC-E concept and is an advanced concept. Do NOT set it to “EMERGENCY!”
unless you want people to call 911 on you!
o. Goto “27 SmartBeaconing” and if you’re going to be mobile, change the status
from OFF to one of the three kinds of profiles:
Type1: driving at freeway speeds / slow subtile turns Type2: driving at on city streets/speed, more significant turns Type3: riding on say a bicycle / slow speed, more significant turns NOTE: SmartBeaconing gets you much more accurate positioning reports at the cost of battery life. If you are less concerned with posits at every turn, consider using a plain 5 minute beacon interval instead of SmartBeaconing
p. Goto “28 TIME ZONE” and either leave in UTC or change to -7 if in California
