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 !
