Not to discourage you, but check the prices of the ICs and Crystals now if
they can even be found .

Hi all,

Way back when I built the AK-1 on perfboard.  Used it with a KWM-1 circa
1971.  I haven't fired it up yet to see if it still works.  I was
considering upgrading it to a AK-2.

The RTTY journal mentions K8JUG having PCB for the AK-1,  I didn't find any
reference to there being boards for the AK-2.  Does anyone know there were?
Or perhaps gerber files exist somewhere.  

It just occurred to me as I type that the ST-6 set of boards probably
included.  I'll have to go research that.  I know at one time images or
gerber were floating around at the time.

I would consider doing my own layout and boards if I don't find anything.

Pointers appreciated.

John, W9DDD
