- As there was no datasheet available for the tuner module, some sources say that such are more or less alike, so here are two UHF modules to see about culling some common basics from. Sadly, however, this does mean that the actual capabilities of the tuner are not known - though I would expect as it is a UK market item we'll be looking at UHF-only ch21-69 (471.25MHz-855.25MHz), mono, prob. locked to PAL-I freqs., IEC-output. We may be surprised, but I won't hold my breath...
