"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.
+----------------------------+
| Modifications for the 2005 |
+----------------------------+
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.
