Mon 01-29-1990 [07:38] "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 +----------------------------+ | Modifications for the 2004 | +----------------------------+ 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. --- ~ DeLuxe 1z11a20 #2989 pneumonoultramicroscopicsilicovolcanoconiosis ~ QNet 2.03: NorthAmeriNet: Sound Advice BBS ~ Gladstone ~ MO ------------------------------
