Hi, All

It seems to be a common problem the 12C509A JW devices. I have just designed a product using a 12C509A (JW) pic for wireless data transfer with a Chipcon CC1050 transmitter. When using the 12C509A (JW) pic my project works perfectly and on frequency but here is the catch.

When I use the excact same program but I program a 12C509A (OTP) pic I can still see my transmitter transmitting but it is transmitting faster and it is not on frequency and it does not transmit full power. 
JW - 433.135Mhz
OTP - 433.085Mhz

If there is any body with any suggestions please will you help me.

Many Thanks,

Gary Gasson'
