APRS With The Hytera PD785G
Table of Contents
I’ve read many articles about the Hytera PD785G, APRS, GPS, IPSC2, DMR+, Brandmeister and what not…
These are the settings that I currently run with.
GPS settings #
These settings remain the same as on the v8 firmware.
Also this remains the same – make sure to disable Quick GPS and enable RSSI Report.
You do not really need the other settings. On incoming calls Call Location will show the location of other stations on the display. Voice with Location sends your own location info out with your voice. This is needed for Call Location.
Network settings #
Set the Control Center ID to
9057 if you want to appear as portable device.
You can also use any of those number-symbol combinations.
|RRS & Radio IDs||description|
|9055||house / QTH|
|9056||camping / fieldday|
|9058||mobile / boat|
|9059||mobile / car|
Channel settings #
Setup the channel like this. Just make sure to set
Location Info Revert Channel. I did not select
IP Multi-site Connect and I also did not select an
RRS Revert Channel. I am not 100% sure, but I think the RRS Revert Channel
is what makes your HT send your position out when you change channels.
You can also set
Slot Operation to
Pseudo Trunk – that would let you hear statically linked talkgroups of
another timeslot too.
Did you set
Button as a GPS Trigger? Then you want
to configure a button here.
Basic settings #
For what I have tested this works quite well. Although Brandmeister
recommends to set the
Data Bearer Service to
Compressed IP if you want to use text messaging.
In-call location information does not contain an SSID. That means, that your
location is transferred as your plain CALLSIGN, without the
When transmitted with SSID a location point looks like this:
and without SSID:
There is usually only a red dot marker and not a house. The house replaced the red dot when I tried new APRS settings with my Openspot2 – which sended out a beacon for my callsign only. This might not be compatible to each other – time will tell…
In case you don’t know that site yet, there is also
an alternative to https://aprs.fi – I love the realtime raw package feed.
I use them both here and there.
