Good Morning All,

I have a CMOS Si570 mounted on a Lite+Xtall board and am obderving 
strange behavior of the RF output of the device.

The RF output is on for about 4msec, goes off for about 2msec, and 
continues to repeat this on-off pattern continuously.  The frequency of 
the RF output is about 50MHz during the on time.  The RF output 
envelope displays sudden transitions from on to off or off to on.  The 
PIC on the board acts as if I2C communications is proceeding normally 
with each DIP switch input change but results in no change in the RF 
output of the Si570.

Has anyone observed proper operation of the CMOS Si570 devices I have 
been filling orders with in recent weeks?  Also, has anyone else 
observed faulty operation of a CMOS Si570 device?

Thanks and 73,
Tony KB9YIG
