I've run FHEM on a Pi with an SCC to communicate with about 6 FHT80B for 4 years now.
Recently we remodelled the house and I added two more FHT80B.
Was having the usual trouble with FHT80B going to sleep and the SCC only picking up actuator information.
As per usual I went through the steps on https://wiki.fhem.de/wiki/Kommunikationsprobleme_mit_FHT
However for the past few weeks I am getting no information from any of the units.
EDIT To clarify I am not even seeing the actuator information in the FHEM event monitor.
The more I look the more I suspect that I have a problem with the SCC.
How can I test that the SCC unit is actually capable of receiving any radio signals?
Here is info the current page in FHEM for my SCC. You can see it is responding to cconf and there is raw data in the buffer.

Here is the log I get at startup:

Which looks ok as far as SCC is concerned.
The yellow LED is flashing slowly on the SCC PCB
Now given that I only have FHT80B units to play with, which are notoriously flaky anyway, what can I do to diagnose my issues further (I do have some unused windows switches too)?
It seems to me like the SCC is not picking up any radio activity at all, as though the aerial is broken?
