Unexpected address `002029569` for FLEX message in 1.1.8

I received the following via MNG 1.1.8:
FLEX|2022-06-03 10:53:33|1600/2/K/A|13.059|002029569|ALN|P 1 BRT-01 BR woning Toscalaan Hoogvliet Rotterdam 173151 171631 173131This is unexpected and some googling results state that 002029569 is a group message. I see that 1.1.9 has the following change mentioned:
- FLEX: Changes to group messages and delimiters.
I expected several other addresses to show. Is this fixed in 1.1.9 or have I misconfigured MNG? I expected a list of addresses instead of 002029569.
I know that the following addresses are a somehow available as they are listed on a website:
- 1400349
- 1400551
- 1400599
- 1400605
- 1400651
- 1400999
My thoughts: it missed the set of instructions. Aka the frame that became prior to this group message.
Recently (6 days ago) my long running setup also started missing messages. It turned out they have changed something to the P2000 paging network. The signals came in much stronger than usual and overloaded the SDR. I made recordings with rtl_fm and sox with various gain settings to pick the right one.
@bierviltje are you running v1.1.9?
I would be interested in how you did the fine tuning. Maybe via a Twitter DM if you use Twitter? My
Edit: Please discard my previous comment, I came to the conclusion I was running on 1.1.8 as well without knowing.
Yes this issue is fixed in 1.1.9
Not sure if this has been mentionec anywhere but FLEX offers up to 16 groupcodes, in the range 2025968-2029583
Since there can be multiple groupcalls at the same time, these groupcalls need to be seperated somehow. The first groupcode is always 2029568. The busier the networks becomes, the higher the groupcode. So if this application only supports 2029568, it really has to support all 16 groupcodes in order to receive all groupcalls.
