"Someone who is interested"???  Heh heh heh.  Yeah, I don't listen to
the CMT band, either.  That ECPA has got me just _petrified_, hi. :-)
I got these off a bulletin board.

There is a socket that is not marked so it will be referred to as D501.

 D501 and D503 removed     :  Scan rate of 6/12 cps
 D501 only installed       :  Scan rate of 7/14 cps
*D503 only installed       :  Scan rate of 8/16 cps
 D501 and D503 installed   :  Scan rate of 10/20 cps (horray!)
*D502 installed            :  Disable 823.95-850.95 MHz and
                                      868.95-895.95 MHz
 D502 removed              :  Full coverage from 760-1300 MHz
 D504 installed            :  Normal spacing for all bands.
*D504 removed              :  Enable 30 kHz spacing in areas
                              restored by D502 removal
* = Stock US model configuration

1.  Remove diode from "513" to get excluded 800 MHz freqs.
2.  Install a 1N914 diode in "514" to increase scan rate to 10/20
    channels-per-second.
3.  Install a 1N914 diode in "510" to get the extra 100 channels.
4.  Remove diode from "D-44" to restore missing frequencies in th
    806 to 960MHz band.
5.  Remove diode from "D-45" to restore coverage from 68 to 88MHz.
------------------------------------------------------------------
In step 5 above, I have no idea what this is for.  My 2004 came
from the store already scanning this range, and this was the first
I had ever heard of it.  The same goes for step 4.  When I removed
D513 (as in step 1), I got those freqs back.  Perhaps the user who
originally posted these had a radio from a different production
run.  All I can "vouch" for is steps 1, 2, and 3.
