Using GB7WF Transmit Timer is 3 minutes, please
leave a gap of at least two seconds after the beep for the timer to reset. Call sign settings to use with GB7WF, YOUR: (UR) CQCQCQ RPT1: GB7WF B (note the Port letter
B must be at the end of the line in the 8th position) RPT2: GB7WF G (note the G for
Gateway must also be in the 8th position)
MY: <your callsign> Also very importantly there is a valid
reason that we request that you please DO NOT use Auto GPS beacons through
the repeater. DStar transceivers wait until the frequency is clear before
transmitting Auto GPS Beacons. This sounds ideal but in practice if it
collides with the next users data header it can stop their transmission from
being passed through the repeater and or the Gateway onto the network. Manually transmitted GPS information is welcome and if
configured correctly will be sent to the APRS servers (see below). Gateway Operation. To use the Gateway on GB7WF you will need to be
registered on the D-Star network. Registration requests are only accepted
from users within the RF coverage area of GB7WF. If you are a local RF user of GB7WF and wish to register for
Gateway use then you need to send your full name, callsign, a valid email
address to admin@wfrg.net. If you are not local to GB7WF then please contact your
local keeper for registration. Click here

Robin AA4RC is Dplus System. When installed on a DStar Repeater,
this system allows users to connect to any Reflector (Conference) or other
Dplus enabled Repeater directly anywhere on the DStar network. Click

MIDSTAR (UK) guide GB7WF Data & Tracking (setting up GPS) Click here to download a printer friendly version of this
setup procedure GB7WF is more than just a voice
repeater. It also carries low speed
data, which can be used for computer communications and APRS style tracking. This section explains how to set up
GPS TX MODE (DV-G), not GPS-A, so your position will be shown on other DStar
transceivers & the APRS servers. To set up your IC-E2820 & IC-E92D
to use GPS (DPRS) mode you will need to create a checksum code to enter in
the GPS message in the 2820 & the 92, this can be done by using the D-PRS Calculator created by Pete Lovell AE5PL. To set up your IC-E2820 to send GPS
Data (DV-G) you need to set the following parameters, MENU > DV GPS > GPS SENTENCE = RMC & GGA on, all others OFF GPS TX = GPS (not GPS-A) GPS AUTO TX = OFF (GPS data will be transmitted
when you press your PTT) GPS MESSAGE = (enter your checksum code created by
the D-PRS calculator) When your 2820’s GPS is receiving a
valid signal the GPS symbol will stop flashing (this can take sometime) so
when you press your PTT valid DVG information will be transmitted. To set up your IC-E92D, MENU > DV SET MODE > GPS TX MODE
= GPS > SENTENCE = RMC & GGA = ON, all others OFF. > GPS AUTO TX = OFF (GPS data will be transmitted
when you press your PTT) MENU > MESSAGE/POS > GPS >
(enter your checksum code created by the D-PRS calculator) On your 92’s display you should see DV-G,
and when the light is flashing (GPS lock) on the HM-175GPS speaker/mic and you press your PTT
then you will be successful transmitting DVG. The Checksum code is unique to the
callsign & the APRS symbol that you select in the D-PRS Calculator. Call signs will only be plotted if the
user is sending the correct DPRS/GPS Information. |
