One thing I find interesting in electronics consultancy is all the various "standards" people have stumbled on for debug UART connectors.
Ours: 3-pin Molex KK (centre GND, pin1 DUT transmit, pin3 DUT receive). Hate it or love it?
Common: TRS jack. Inconsistent pinout.
Common: 2.54mm pitch (dupont) non-polarised (annoying)
Common: DB9, but they can't decide if they are DTE or DCE, or which gender you're supposed to use for which. have your null modem & gender changer on standby. Also sometimes not even RS-232.
Semi-Common: Something fucking annoying and weird that is hard to crimp and/or expensive. Ranges from Mini-Fit Jr. to fucking board-mount lemo or fischer.
Cursed: Micro USB but it's not USB it's 5V TTL UART seriously why?
Let me know what you've seen... #electronics

New one. Simoco SRP1000. Been missing one of these from the collection for a while and saw one come up on eBay. Basically an SRM1000 in an extremely large, heavy but allegedly “handportable” enclosure. Probably not much chance of programming this one but still a nice bit of history to own. Weighs about 700g, apparently 3W Tx. Might have a go at powering it up this evening and do a teardown too. #tetra

I also generally need to work out whether there are going to be issues with how signalling is sent in this situation (I.e. will stealing be done correctly, is code already in place to manage when it should be done - is the downlink channel traffic or assigned control right now, etc). This is so bloody complicated, I’m not surprised it has taken so long for a functional open source TETRA stack to be born really.

2026-06-05 18:54:20 GMT

- reply

Groups are tricky too. When a group call starts, basically a PDU with associated channel allocation is sent down addressed by that group to go listen to the traffic channel for the call. But then we may have individually addressed signalling to specific members of that group during the call. So this will bump into the MM (Mobility Management) entity (which knows which radios are attached to which GSSIs) as well.

2026-06-05 18:50:05 GMT

- reply

It’s actually easy to know when a radio is sent off to an assigned channel, that’s no problem. Tracking when they come back is difficult because that’s down to a lot of MS-side logic (timers, counters etc). In many situations they can just return to the MCCH silently and we have to deal with that. There will be a lot of “fuzzy” states I think where we have to send a copy of signalling down on the last-known channel but also on the MCCH as a backup. Maybe repeated LLC delivery failures could also trigger a “cache invalidation” too, prompting us to assume an MS returned to the MCCH. Hmmm…

2026-06-05 18:46:30 GMT

- reply

Basically at the moment we always assume every MS is listening to the main control channel (MCCH). So if we need to send some signalling down to a radio and that radio happens to be in a receiving a call at that moment, it won’t work (except for signalling specific to the call, because that is handled properly, complicated…)
So what is needed is some central place to track which channel every MS (actually every SSI, including groups) is currently listening to. This will form the foundation for energy economy too, I think (knowing which slots MSs are awake for).
Lots to do. Not much dog brain capacity.

@nprofile…z9l8 our usage is always zero in the "typical" period they have the saving session, so we can't really reduce from that (we've already moved all our usage away from peak times, which is great!).

Explanation: when the BS sends down a PDU to an MS that invites some sort of immediate response, automatically grant a slot along with that PDU’s downlink resource so the MS has an immediate uncontended opportunity to send that response. Typically this is to support the LLC’s basic link acknowledgments (a bit like TCP ACKs) but also helps in some other situations where there is a quick BS-initiated exchange of PDUs. Without this mechanism, MSs would have to go through the random access procedure every time.
