On Tuners and UHF Mods/Adapters

[wa2ise]

Just to see if it would work at all, I connected a tube based UHF to VHF converter to an antenna, and the output to a HDTV converter box tuned to channel 6. The tuning was rather fussy, I think because the converter box doesn't expect the digital carrier to be that much off in frequency. Also the UHF converter may add too much noise. With the UHF converter, the resulting digital carrier on channel 6 could be anywhere. A vintage TV set with fine tuning could cope easily.
