Using the "+0.5" switch with the Aux Band

Do not adjust your monitor (or your TV). What you're seeing is real (though it wasn't real fun going cross eyed studying the '830 Service Manual for several hours on end).

This is a proof-of-concept shot of the Aux Band-expanded TS-530SP - the guinea pig for the mod series I've documented - receiving my signal generator on the indicated frequency. It's 500KHz up from the "base" allocation we added on Page 2. I'll follow with a several shots out of the manual describing how this works, what needs to be added to the Counter Unit to get the indicated range...then lastly, how to use the +500KHz panel switch to select the additional range as is done with 28 and 29MHz. What we'll end up with is complete coverage from 27-30MHz - useful for the oddball transverter IF. As stated before, don't jeopardize your license by using non-certificated gear on a band which requires it. Listening is fine. Keeping the Heater switch off keeps one honest.
