    Nice Mod! Makes you wonder why the manufacturer couldn't spring for a cheap capacitor. But they pinch pinnies when it come to cheap radios.

      Yeah I know right? It such a easy thing to do but I guess it just wasn’t in the budget. 😜

    Great idea !
    However, something is not right.
    The time [t] it takes to a capacitor [C] to discharge [DU] at some current [I] is t = DU*C/I.
    If we consider the clock stop at 2V we have DU = 1V => t = 1*10E-6/(100E-6) = 0.1 sec.
    (the current is 95uA from the teardown measurement; aproximated to 100uA here)
    So, for we to have 10 sec discharge time we need to have a capacitor 100 times larger than 10uF => we have at least 1000uF there.
    Can you verify what is the situation ? Either the capacitor added is 1000uF or something was going wrong when you first changed the batteries (like for instance pressing a button by mistake ?)
    ps - i'm kind of a geek myself with radios :)

      I just checked and it is a 10uf cap. I powered the radio with a power supply and lowed the voltage until the display went out. The voltage at that point was 1.64 volts

      @@TheRadiogeek 🙂Yeah, those ceramic capacitors are usually small. I was looking at those electrolytic capacitors (one on the left and one on the right) and they seem to be 2 x 470uF. It is possible that they are holding most of the backup energy and that little one added helped them doing it.

    • @TheRadiogeek
      @TheRadiogeek  3 года назад +1

      @@IAdryan I don’t think so because without the 10uf cap installed the display go out almost instantly. The radio loses it time before you can get new batteries installed.

    I see that the AM coil wires are right over the metal speaker frame and magnet. That can't be a good idea.

    • @TheRadiogeek
      @TheRadiogeek  3 года назад +1

      Yes it not a good idea. I guess they ran out of room and or just didn’t care. Slap it together and get it out the door. 😜

      I'm guessing that a fairly easy mod would improve things a bit. I had the Horologe (sp?) version of that and the AM wasn't all that bad. The AGC circuit wasn't the best, though.
