A 120VAC/20A circuit is appropriate for a lot of things....  a 1500W HF
amp is not one of them.

Just do the 240 circuit...

Twisted pairs, steel conduit from service to sub, sub, to outlets,
240VAC/60A sub-panel, 8 x 120VAC/20A, 2 x 240VAC/15, 2 x 220VAC/20A

Just find an electrician who will inspect/sign off on the work.

With the K3/KPA500 as it is I get a just perceptible flicker in the room lights when keying.  With a dedicated 240 volt line I could also add a cooler for the drinks.
