title: APRS With The Hytera PD785G
summary: >
This article is based on the Firmware v9. If you still have v8 do not upgrade---
the v8 is still the better choice! If you need a tutorial for v8 have a look
at [this website](https://dmraustria.at/gps-einstellungen-fuer-aprs-bei-hytera-geraeten/)---
it is in german though.

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*.
{{< figure src="hyt_02_gps.png" alt="GPS settings" caption="" >}}
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 |
| :--- | :--- |
| 9050 | without SSID |
| 9055 | house / QTH |
| 9056 | camping / fieldday |
| 9057 | handheld transceiver |
| 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.
## Buttons
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][bm] to set the `Data Bearer Service` to
`Compressed IP` if you want to use text messaging.

## Examples
In-call location information does not contain an SSID. That means, that your
location is transferred as your plain CALLSIGN, without the `-7` for
`9057`.
{{< figure src="hyt_08_aprs_route_9057.png" alt="route with the ssid 7" caption="The route looks like this when transmitted as CALLSIGN-7." >}}
{{< figure src="hyt_07_aprs_route_9050.png" alt="route without ssid" caption="The route looks like that when no SSID is appended to the CALLSIGN." >}}
When transmitted with SSID a location point looks like this:
{{< figure src="hyt_09_aprs_ssid_working.png" alt="location with ssid" caption="" >}}
and without SSID:
{{< figure src="hyt_10_aprs_ssid_notworking.png" alt="location without ssid" caption="" >}}
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 ~~<https://aprsdirect.com>~~ as
an alternative to <https://aprs.fi> -- I love the realtime raw package feed.
I use them both here and there.
