for the radio wizards

There used to be a device called Switch 8. It was a similar channel expanding set-up. Ric at PMD used to sell them. He may still. I haven't heard anything about them since a couple guys planned to use them on their radios, back on the old gt forum. Some sort of digital decoder, I think, that used one radio channel to give you 8 more functions. Not really sure how well they work.
