If anyone out there has any that aren't listed, please mail to me! 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 (Mutes any audio that follows the paging signal) 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. /---------------------------------------------------------------------------\ | Standard C520/528 - Keypad Guide | |---------------------------------------------------------------------------| |Key| Alone | With "FUNC" key | Key alone in set |In Set With "F" | |---------------------------------------------------------------------------| | 0 | 0 |Enter Set Mode |Mute keypad bleep |Set Band Edge Limit| | 1 | 1 |PTT Lock |1/5 beeps when paged|Tx wait on c-b rept| | 2 | 2 |Dual Watch |1kHz entry on keypad|Match CTCSS on scan| | 3 | 3 |Output Power |Tx Delay on repeater|Switch UHF Bands | | 4 | 4 |Frequency Lock |Mute noises dur sql |Dir Input 4/3 figrs| | 5 | 5 |Battery Saver |Automatic power off |No audio after page| | 6 | 6 |Select Step Size |Enable tune in lock |Fast tune 1MHz/100k| | 7 | 7 |CTCSS select TX/RX |CTCSS tone frequency|Single/Dual tone MF| | 8 | 8 |Repeater Shift +/- |Set Tx/Rx split freq|Cross Band Repeater| | 9 | 9 |Reverse Repeat Shift|Make LAMP button REV|Up/Dn keys do 10MHz| | * |Step Down|Search 1MHz band | | | | # |Step Up |Memory Shift | | | | A |Cancel | | | | | B |Pager On |Set Pager Codes | | | | C |Mem Scan |Partial Memory Scan | | | | D |Dial/Mem |Store Dial In Memory| |Extend RX coverage | |---------------------------------------------------------------------------| | Expand:VHF F+0 F+D A | Independent Transmit/Receive Frequency | | UHF F+L F+0 F+B F+L F+3 A | [Rx] F+D <mem> [Tx] F+D F+A F+<mem> A | | VHF F+6 step to 12.5MHz A | Remove Independent Tx Freq From Memory | | F+8 F+8 F+C | F+D F+A <mem>+A F+A A | | tune down to 144.9875 | Clone One Set To Another | | F+0 F+D PTT F+8 F+C | B B F+0 F+* [PTT] on source set | \---------------------------------------------------------------------------/ Origin 2:252/140 @ fido :: 17/09/91 :: sysop@f140.n252.z2.fidonet.org
