Stan, did you happen to notice that the TX-118S-4 V2 (and V1) have swapped the #1 and #2 outputs from any other transmitter?
I have three or four keyfob transmitters, all of them are consistent that A = 1, B = 2, etc. However, these transmitters send output #2 to the first receive channel and output #1 to the second receive channel! I have to wonder if that's why they're being sold so cheap, someone ordered them and they were screwed up, so they had to fix them and go again.
I'm going to swap those two channels on my transmit board so these boards agree with all the other transmitters.
