Is the Standard C528 in use out there in the states, and does anyone have any
other mods for the set barring these:
Standard C520/C528 Modifications
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This file is a compendium from to others being bandied about the place. It
is hoped this will be the better of them, being the easiest to follow!
o To open up the rx only up on the unit on VHF:
VHF F+0 F+D
o To add 320-400MHz, 400-480MHz, 820-900MHz, 900-980MHz:
UHF F+L F+0 F+B F+L F+3 A
o To Expand Tx/Rx coverage, do both the above in that order, then:
VHF F+6 change step to 12.5MHz A
F+8 F+8 F+C
Tune down to 144.9875
F+0 F+D PTT F+8 F+C
o To Store independent transmit/receive frequency in one channel:
Enter receive frequency into dial
F+D <mem number>
Enter transmit frequency into dial
F+D F+A F+<mem number> A
o To Clear the tx assignment offset:
F+D F+A <mem number>+A F+A A
o To Clone one set to another:
B B F+0 F+PS then key up on the set to clone from
Set mode key assignments:
The set mode allows a number of user parameters to be customised according
to individual taste. Set mode is initiated by pressing F+0. The following
are entered after going into set mode:
0 Turns off the beep tones on each keypress
F+0 Sets band edge limits, i.e. 0079=100-179, 400-479. 3060=130-160
1 Changes count of paging operations tone, one beep or 5
F+1 Set tx delay on carrier drop when using as cross-band repeater
2 Enables entry of the 1kHz figure on direct keypad entry
F+2 Stop scan on busy channel even if CTCSS doesn't match
3 Sets mod delay on paging Tx to either 450ms or 750ms
F+3 Switch UHF bands between 300/400/800/900
4 Mutes short noises during squelch operation
F+4 Keypad entry of 4 digit or 3 digit frequency
5 Turns on and off the auto power off function
F+5 Pager Audio Mute (effectively disables pager)
6 Enable/Disable the rotary channel knob when keypad locked
F+6 Fast tune (F+KNOB) gives either 1MHz steps, or 100kHz
7 Sets the CTCSS tone frequency
F+7 Either Dual Tone Multi Frequency, or Single Tone Frequency
8 Sets the offset repeater frequency
F+8 Cross Band Repeater Enable/Disable (Identified on display by a ".")
9 Changes the LAMP button into the REV button
F+9 Up and Down keys either act as the knob, or as 10MHz steps.

| To Expand Tx and Rx coverage: |
|---------------------------------------------------------------------------|

| UHF F+L F+0 F+B F+L F+3 A ; Gives 300/800/900MHz |
| VHF F+6 step to 12.5MHz A ; This appears to set a special condition |
| F+8 F+8 F+C ; within the unit which is stored with F+C. |
| tune down to 144.9875 ; All params must be correct for it to work |
| F+0 F+D PTT F+8 F+C ; And Store it |

|---------------------------------------------------------------------------|
