ar1000.3

        First of all, if you replace the first "8" with "0.5", you get an
        AR-1000 with coverage extended down to 500 kHz. This may not work
        on older units. My unit didn't let me program any frequency lower
        than 0.5 MHz, or higher than 1300 MHz. Anyway, my aim was to try
        to get rid of the 600-805 MHz gap. I tried the following sub-bands :

                   0.5 -   29.995
                  30.0 -  219.995
                 220.0 -  409.995
                 410.0 -  599.995
                 600.0 -  904.995
                 905.0 - 1209.995
                1210.0 - 1300.000

        To choose these values, I made the following assumptions : the
        original values never exceed a 190 MHz span for the "561.225" series,
        and never exceed a 304.995 MHz for the "251.575" series. I was careful
        not to exceed these ranges, because of the necessarily limited span
        of the internal VFO.

        These values did seem to work, since I was able to hear some TV signals
        near 620 MHz, that is, in the previous gap ! However, when I programmed
        some search banks, it sometimes refused to search, even on "authorized"
        frequencies (around 450 MHz). And, since there is nothing but TV
        channels between 600 and 805 MHz (at least in France), I restored the
        original values (except for the 0.5 MHz lower limit).

        Now, if you find something interesting, please keep me informed !
