This is an old post but I was just having this same issue. It came down to how the command is "built" in the SIMPL+ module. It takes the channel digit, multiplies it by 4, and then converts it into HEX. Well because HEX caps out at 255, any channels about 64 (technically 63.75) will start to have strange behavior. Here is the SIMPL+ code for reference:
if(DTV)
makestring(sChannelCommand, "\x08\x22\x04\x80%s%s", chr(iMainChannel * 4), chr(iSubChannel));
I'm trying to figure out why the module needs to multiply it by 4. It only does it for DTV and not ATV.
1. Has anybody tried getting rid of the "*4" and would the TV accept the command?
2. If the "*4" has to stay, how do you format longer channels in the string?
For example this is the string to go to channel 47.1:?\x08\x22\x04\x80\xBC\x01\x95
Does there need to be a "high channel"?
