Andre, 

     For whatever it's worth, that site seems to be dead at the moment.

Subject: Re: [aprssig] Using a TNC as a CW Beacon Only

I actualy have a CW beacon right here using nothing more then a 555 
timer and an eprom together with some odd bits.
You can find it on the http://www.pa3gco.com site.
It can be modded to run when you puch the ptt or run all the time, it 
can key the transmitter for you.
