Being a new owner of an IC746pro which I used in the CW contest this past
weekend revealed a problem in that the first element of code is sending for
example "AD9SV" instead of KD9SV which was programed into the F4 menu.
Using a foot switch overcomes that problem "if" the switch is activated
before CT keying starts. Reading in the CT manual (v9.37) page 19 says:
"CT also provides a PTT (push to talk) control signal on the parallel ports,
which is asserted one baud (dot period) before CW sending begins. This
provides time for amplifier relays to close before RF arrives from the
transceiver, in cases where the amplifier switching is slow or the
transceiver sequencing is poorly designed"
My question to the reflector: is it possible or can the QSK/TR input of my
antenna switch/keying circuit be paralleled (Hsend signal and PTT from CT)
without causing problems? If I transmit without CT or the Hsend connected I
will toast my changeover relay/pre-amp circuits. Has anybody reading this
had problems of not sending the first code element and found any other
solutions. Thanks in advance, de gary, kd9sv
