The great advantage of the 504 is that signal strength can be simply checked by cycling the display button for every tuned channel. I do not think this feature exists today on M items that include a tuner.

I might be wrong on this but coupled with a decent aerial (4 pole is quite adequate here, not too directional) it is possible to get all national stations at signal strength 8 (max). Local stations tend to broadcast from the most convenient available mast and these can be received at signal strength 4 to 5, which is perfectly acceptable here.
