What? Modify a Collins? If it needed modification, Art Collins would have already incorporated the modification.

Well maybe. Art didn't live in the new millennium.

Art intentionally made the 30S-1 cabinet large with lots of space so that ardent amateur radio operators could make enhancements to his design that he would be proud of. I'm sure.

He didn't include 160M into the 30S-1 because the KWM-1 did not have 160M and neither did the KWM-2. The 30S-1 was to be the companion to these two transceivers. Since they did not have 160M, why include it in the 30S-1? But he left plenty of room to include 160M as proven by Chris,
