Have built the keyer, but did not put the CW Speed Pot. Question is the pot
necessary for operation.?
Also did not hook up anything to the "pbck or rec" Everything else is
installed and has been checked by
A second party. The only test instrument that I have is dvm and vom. There
is activity at the Xtal terminals,
But do not know if it is the correct freq or not. I get keying at the input
of U2 the 68hc705p. There is no output
>From this chip. Anyone have any idea's on anything to check or on what is
bad. My next thoughts is to get
Another 68hc705p to see if the chip is defective.
