Hi everybody, I am trying to set up a CW-PPT trough LPT1 the keying (pin17) works all ok but there seems to be not output on pin 16 for the control of the PTT except a very short blip (abt 50 msec) when switched to transmit. Any helping suggestions ? 73s Gerd, DJ5BV -- WWW: http://www.writelog.com/ Submissions: writelog@contesting.com Administrative requests: writelog-REQUEST@contesting.com Problems: owner-writelog@contesting.com
