If you look at the pic in the upper right, over London area it is just awashed with colour, the Red and Orange represent good to very good
Tropospheric ducting. I had a good QSO with a Ham in the Liege area of Belgium who said that he often uses APRS so I thought Hmmm
I’ll give that a go myself and I was very surprised by the results I have to say. Firstly as this was my first real attempt at APRS I was sort
of expecting distances of around 80 miles (with ducting) but the distances just got further and further as the evening went on and I
believe that a lot further is possible with greater propagation than the results even I achieved. So how does it work? Well one of the best
articles to look at would be https://en.wikipedia.org/wiki/Automatic_Packet_Reporting_System
I will say though that it’s a real time communication of things like GPS (Lat/Long), Weather conditions, Text Messages, Telemetry and
other useful information about your own region. I have put together a list of Some of the stations I picked up from the 30th December
2019, I will stress that this is only a few there were many many more believe me.

30th December 2019
Okay, since putting this page here I have found out a lot more info on the subject, one of the things that I found out
was that it uses Digipeaters (Digital Repeater), well I don’t want to use Digipeaters so this isn’t really for me, But I
will say that it’s a good mode if people are interested in positioning etc, It’s Just not for me.
A good monitoring system can be found at aprs.fi

Ok, recently I have been delving into the world of APRS
(Automatic Packet Reporting System) Now I will admit that
up until 2018 I had no clue as to what APRS did,
therefore it was on my radio but alas never used, but that
was upto as I said 2018 when I started to play around with
it a little, looked into it online and thought “Hang on I can
do that”. Well I must admit I now enjoy it quite a lot.
On the 30th December 2019 we had a very good tropo lift
on FM so I decided to give it a real go there and was
impressed with the results I received.
