Test base station response to receiving component serial number that is less than 5 characters #4

Hi. I think I'm having this problem with my setup. On my 315Mhz receiver, my base station appears to be transmitting 3 character serial numbers and that throws off the message parsing.

Here are some examples of a 'keychain remote off' from my base station (after nibble swaps):

Raw: CC05333133480D05BC3FFFFA Raw: CC05333133480D05CC3FFF0A Raw: CC05333133480D05DC3FFF1A Raw: CC05333133480D05EC3FFF2A Raw: CC05333133480D05FC3FFF3A Raw: CC05333133480D050C3FFF4A Raw: CC05333133480D052C3FFF6A Raw: CC05333133480D053C3FFF7A Raw: CC05333133480D056C3FFFAA

I added the extra 'FF' at the end because there was an odd number of bytes showing up in the message that caused more parsing problems. Somehow a checksum gets added. Do some systems have an alternate base station msg format?
