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. {{< figure src="hyt_05_buttons.png" alt="buttons settings" caption="" >}} ## 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.

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... {{< figure src="hyt_11_aprs_ssid_hotspot.png" alt="hotspot beacon" caption="" >}} In case you don't know that site yet, there is also ~~~~ as an alternative to -- I love the realtime raw package feed. I use them both here and there. {{< figure src="hyt_12_aprsdirect.png" alt="aprsdirect.com station info" caption="" >}}
