An external switching device, such as the Ameritron, 
work well.  

If you do not wish to use an external box, some amateurs 
are using the "soft-key" boards for their legacy 
amplifiers (Collins, Heath, Drake, Dentron) from Harbach 
Electronics.

Instructions for interfacing provided on web site and 
Jeff answers specific questions for other amplifiers.
