MB7DAA UK's First standalone licensed DMR APRS Node **144.700 UK wide frequency**



Imitation is the sincerest form of flattery
http://blog.retevis.com/how-to-use-the-rt82-built-in-gps-to-report-aprs-location/ 

The idea to have a common frequency for DAPRS is to help create a better gps / DAPRS network and allow people to use their GPS compatible radios to send their location data.
Other DMR radios will be able to send a text message via the aprs network and receive as well, they could send a static GPS message if they wanted to.

As I understand it, some repeaters allow GPS data in on talkgroup 5057, but at the moment I can do this on a phoenix repeater.

Having the option to run a node, even side by side an existing analogue one would be very useful.

Go to the BrandMeiser self care website: www.bm-dmr.uk/dash/APRS1.html
set up your details example screenshot below







Now in the radio,

Create a new contact private call on 5057


Next create a channel



Set up GPS system



Now add the channel to a zone




Save the codeplug to the radio, select zone DAPRS and channel DAPRS (so we are 144.700 cc1 ts 2 and will pulse GPS data every 30 seconds on talkgroup 5057 private call)

Next the host spot just needs to be set to RX TX o 144.700 and DMR BM UK server





You will then be able to see the SMS messages in and out from the dashboard (Ignore the dstar bit)



Results can be monitored on https://APRS.fi

Astro-Pi "Mission Space lab" who's interested?




Mission Space Lab

Chertsey Radio club is inviting anyone aged under 19 years old to join us in creating some Python code, which will harness the full sensor range of the raspberry pi and sense hat (astro-pi) and could be run n the International Space station.

We will be visiting the Egham Raspberry Jam at the end of this month and will be running online sessions to help our teams prepare and upload their projects.

If you are a school, code club, or group of people interested, please get in contact we will help you!




Mission Space Lab offers students and young people the chance to have their scientific experiments run on the ISS. Your challenge is to design and program an experiment to be run on an Astro Pi computer. The best experiments will be deployed to the ISS, and your team will have the opportunity to analyse your results and put together a short report about your findings. The ten teams that write the best reports will be selected as the Astro Pi Mission Space Lab winners!

Who can take part?
Anyone who is 19 years or younger
In teams of two to six
Supervised by a teacher or mentor
50% of teams’ members need to be citizens of an ESA Member/Associate Member State

Please contact us if you are interested via our club e-mail chertseyradioclub@hotmail.com
