in fact I forgot to bind trx1 and 2 to the cell…
now I also see trx2 slot2 scanning (with a-crc-errors) but no result regarding the stations:


dect-transceiver-list --name trx2
DECT Transceiver trx2 at cell0:
	Type: sc1442x
	Features: slow-hopping,p64
	RF-band: 00001
	Events: busy: 0 late: 0

	slot 0: <scanning> packet: P00 carrier: 23 (1921.536 MHz)
	    RX: bytes 0 packets 0 a-crc-errors 48 x-crc-errors 0 z-crc-errors 0

	slot 1: <idle> 
	    RX: bytes 0 packets 0 a-crc-errors 0 x-crc-errors 0 z-crc-errors 0
