RE: "police band" - I occasionally hear amateur sideband stuff there around 2MHz and 4MHz after supper. I have another radio (a Silvertone 4660) sitting on top of my 41-255, so when I hear sideband, I turn on the Silvertone and tune it until I get its oscillator to beat and act as a BFO for the Philco. Of course, it's extremely touchy, but it works.
And until recently, CHU Canada was broadcasting time reference at 3.33 MHz, but sadly, they ceased operation after 90 years or whatever it was.
