Dear community.

I made a script which will upload your CPM reading from the radmon.org website and post it to APRS.fi using a Raspberry Pi.

For an example reading look at the following link:
https://aprs.fi/#!call=a%2FPA3GET-10

53°12.24' N 6°33.92' E
2017-05-10 13:24:11 - 2017-05-10 16:52:56
radmon.org radiation monitor using GQ GMC-320plus V4.22 with M4011 β/γ tube. Last reading: 24 CPM on 2017-05-10 14:31:53UTC at Groningen, Netherlands


If interested I will post the script at this forum.

Kind regards,

Hi.
It would be better to shorten the comment text ;)
Not all (radio) devices are able to show text longer than recommended 43 characters (36 if packet contains data extension).
See APRS specification (chapter 8.): http://www.aprs.org/doc/APRS101.PDF
Also 1 minute interval for fixed station is not good idea.
If you have TX iGate (or more iGates) near you, all packets are also sent over the radio, and may cause overload.
For example, I use a 5 minute interval (low APRS activity around my QTH), and send an average CPM for 5 minutes.
I send the packets as an APRS object https://aprs.fi/info/a/GEIGER-PK
And WX (only temperature) I send with interval 15 minutes https://aprs.fi/info/a/OM1AMJ-6

I made change sending radiation to APRS.
Now I'm sending radiation as a WX station telemetry.
Position & temperature - 15 minute interval, radiation telemetry - 5minute interval.
