The bandswitch also switches several other stages. You'll notice the last

jumpers.
It would be an interesting exercise.
Perhaps not worthwhile.
I think it would be very worthwhile, if only because 60M is so much fun.
It does have three empty crystal positions so logically I would need
to add the appropriate crystal for each band,
It does sound like I'm asking the impossible for such an old radio
but the facility is there.
I don't think it would be that bad. Start with 12M.... get a crystal from
ICM, they should know how to calculate it. Then wire the various sections
to use the 10M networks.
Likewise you could probably do 17M with the 15M networks without adding any
additional coils.
Doing 60 or 30 might mean you'd have to add some additional stuff and that
could take some tinkering.
Perhaps the information is on an amateur forum somewhere.
My guess is most of the people doing this are setting it up for 11M or the
various illicit freebands, and using the 10M networks. Doing that is
a good bit easier than adding 60M would be.
