 			  16F628 by Manuel Sánchez Raya EB7HPM. 
    4/01/04 - Version 0b - First Try to program PLL in C failed.
   10/08/05 - Version 1.0 - Frequency control works!!
   18/08/05 - Version 2.0 - Droped several features due to space exahusted. :-(
   29/08/05 - Version 2.3 - First production revised version.

This is work in progress, as the 144 and 50MHz bands works only summing the
frecuency of the FI. FM FI in 10.7MHz dont work yet, it works by now at 10MHz.
As soon as posible a updated version will be released.

Comments and sugerencies apreciated.
