    Blanding makes a good point that if FM had remained in its original band,
    it might have developed more quickly, but things would not have become as good as they became.
    Firstly, he is correct about quarter-wave antennŠ being the size of loaded CB whips.
    Secondly, the band is considerably more susceptible to noise, and I will add Low-band VHF skip.
    Thirdly, it was only 40% as wide; 2/5 as many stations would fit into any market.
    Fourthly, the secondary, beyond the horizon signal that is noisy but interferes would be enormous.

    I will also add that solid state technology and AFC's made receivers much more stable.
    There was a large number of receivers that advertised AM-FM-AFC, but did NOT have AFC's at all.
    Basically, a three position switch meant that it had it; a two position switch meant that it did NOT.
    One receiver had a great idea: when you touched it, it was mono and no AFC,
    but when you let go, the AFC came on and it switched to stereo.
