It works ok, but since the radio is not squelched there is a high number of rx interrupts and error rx packets. Also, some bad packets seems to slip through. Much garbage is seen in the mheard list. Is this normal? Is there a way to workaround this? 73 de LA7ECA The sccstat returns (for instance): speed : 9600 baud txdelay : 5 persist : 64 slottime : 8 txtail : 8 fulldup : 0 waittime : 2 mintime : 3 sec maxkeyup : 7 sec idletime : 3 sec maxdefer : 120 sec group : 0x00 txoff : off softdcd : off Status: HDLC Z8530 Interrupts Buffers ----------------------------------------------------------------------- Sent : 147746 RxOver : 0 RxInts : 30689899 Size : 384 Received : 212184 TxUnder: 0 TxInts : 4982360 NoSpace : 0 RxErrors : 1804229 ExInts : 7823901 TxErrors : 0 SpInts : 1006105 Tx State : busy
