Chris,

I think i'll take a closer look to those Maxon LPD's.

I've seen the ARRL handbooks already, but i want a good syntethized module, and you can mostrly find crystal and transistor TX's.
Not a problem, but i want to change frequency a lot of times.

Nevertheless, thanks for your help, i gave me a new perspective!!
