TRW-24G Help

I have a TRW-24G module connected to an attiny85, which is connected to a USBtinyISP, and OS X. I also have an accompanying TRW-24G connected to the Nordic USB Serial Converter. The attiny85 runs the following code, and the serial port is receiving nothing.

/*
 * PB4	CE
 * PB3	CS
 * PB2	CLK1
 * PB1	DR1
 * PB0	DATA
 */

#include <avr/io.h>

#define F_CPU 1000000UL
#include <util/delay.h>

#define sbi(var, mask)   ((var) |= (unsigned char)(1 << mask))
#define cbi(var, mask)   ((var) &= (unsigned char)(~(1 << mask)))

unsigned char address[]= {0xE7, 0xE7, 0xE7, 0xE7, 0xE7};

void send(unsigned int message);


int delay= 50;


int main(){
	ioinit();
	while(1){
		send(0b01010111010011110101001001001011);
		_delay_ms(500);
	}
}

void write(unsigned int message){
	sbi(DDRB, PB0);		//DATA output for MCU master
	for(int i= 7; i>=0; i--){
		if(message & (1<<i)){sbi(PORTB, PB0);}

euh, CLK1 is now enabled as an output, but it still won’t work.
