Nimit Hongyim <nimith@catsemi.com> reports succes on proramming UHF phoenix radios...:

Hi  Lawrence, 

Good news and thank for respond to me, the GE radio is very fine radio for the repeater set up and for IRLP, 

I spend a couple days to figure out the UHF program and its work finally.  Thank for your program and here the part of them that I changed:

/*==========  MODIFY THE VALUES BELOW TO SETUP YOUR RADIO ================*/

/* radio wide definitions */
# define CCT 4          /* 0..7 carrier controlled timer n*30sec + 30sec [1:30 = 2] [ 2:30 = 4] */
# define REF 13.2       /* ref oscillator in Mhz */
# define SPACE 0.0125    /* channel spacing in Mhz */
# define REFCODE  1     /* 2=13.2mhz ref osc and ch spacing of 5khz ****** UHF 1 CH A/B WILL USED 1 TO CALCULATE THE RX CODE*/
// # define REFCODE  2  USED REFCODE 2 For VHF 
/* note. each channel can have its own refcode but unless you need 12.5khz */
/* channel spacing, we simplified the program to used one reference divider code */

/* for each channel, one has to define the following data... */
/* the first 8 are mode A and the second 8 are mode B        */
struct CH{
    int cg_type;    /* see table 2 in LBI doc, 0 = none or PL */
    float rx;       /* rx freq ie 147.280 */
    int rxcg_code;  /* see table 3A in LBI doc 100hz = 0xB0, 141.3 = 0x51 ,162.2 = 0x91 */
    int cct;        /* TX timeout timer enable for ch 0=none,8=enabled */
    float tx;       /* TX freq ie 147.880 */
    int txcg_code;  /* see table 3A in LBI doc 100hz = 0xB0, 141.3 = 0x51 */
}channels[16] = {
   /*cg    RX freq   cgcode   CCT  TX freq    cgcode */

{ 2,    442.900,    0x91,   8,  447.900,    0x91},     /* WINSYS   ======> CH A if only 2 Ch assiged HERE */
