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.
|
|
|
|
{{< figure src="hyt_01_gps.png" alt="GPS settings" caption="" >}}
|
|
|
|
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.
|
|
|
|
{{< figure src="hyt_03_network.png" alt="network settings" caption="" >}}
|
|
|
|
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.
|
|
|
|
{{< figure src="hyt_04_channel.png" alt="channel settings" caption="" >}}
|
|
|
|
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.
