And first thing I see after walking away from this thread is the following.................

"....these receivers feature triple-tuned RF circuitry, a ceramic filter and TDSP (True Digital Signal Processing) to ensure the clearest, tightest reception."

Read it in an ad.
They don't say single conversion, or double conversion, but they'd be some number of conversions? And maybe the "triple-tuned" means they're triple conversion? But the signal is also ceramic filtered? But that's really ceramic converted?
