My 101zd has a long delay on CW, dots and dashes are equally as long
and I can only transmit CW on MOX but there is no receive on MOX, if I
switch back to PTT there is receive but no transmit, I do hear the
sidetone but no clicking of the relays while on PTT. There is no
change by adjusting VOX or DELAY.

SSB works fine with no problems.

Can someone help me out?
