[Marsupial]

Something interesting is that the presets don't all have the same frequency range. The leftmost are meant for lower-band AM while the rightmost are meant to higher-band AM.

Technically you bypass part of the main tuning circuitery in favor of a set of secondary tuner circuits. Perhaps it has to do with your recap?

On my 47-1230 the stations that I get do tune in quite strong, but I am having the hardest time to find any stations. There isn't much AM reception anyway, everyone broadcast in FM.

Similarly to your problem, my FM tuner isn't as strong as my AM tuner...
