As described in this topic, the situation around the Emmen, Alpnach and Buochs CTR is a bit special. To clarify it shortly:

These three airspaces (class D HX) are only active during military operational hours, and if needed, also outside operational hours. They all have their own Tower frequency to contact ATC, however, they do have a united frequency for airspace activation ("HX Info"). This means, if you want to know which CTR is active, you have to monitor the airspace activation frequency (134,130). This is a kind of "ATIS" frequency, but only for airspace information, not about wheather conditions. After monitoring the airspace information frequency, pilots should contact ATC or send blind transmissions to the corresponding Tower frequencies.

Now, the situation in Skydemon for non-Swiss pilots is a bit confusing. For Emmen (LSME) and Alpnach (LSMA), the airspace activation frequency has been displayed as "Emmen Information" or "Alpnach Information". This implies an AFIS frequency, however, it isn't. For Buochs (LSZC), it is only displayed with callsign "Buochs" without the words "Information" behind it. I know, the AIP for at least LSZC shows just "Buochs" as callsign here, but it isn't expressive at all.

In addition, the airspace information frequency is also displayed at LSPG as "Kägiswil Information", which again, assumes to be an AFIS or a frequency for blind calls, but it is only the mentioned airspace information frequency for all the three control zones. LSPG uses the Alpnach Tower frequency for blind calls, which is missing for LSPG in Skydemon. Check also their website for more information, since LSPG isn't included in the AIP.

I would suggest to display 134,130 at all four airfields with callsign "HX Info" or something similar, and add the Alpnach Tower frequency also to LSPG, other scenarios wouldn't make much sense. Perhaps some Swiss pilots could also make a statement here, since the actual situation in Skydemon isn't satisfactory.
