1. [WriteLog] PTT timing (score: 1): Author: W7OM@aol.com (W7OM@aol.com); Date: Sun Jun 8 15:21:19 2003; Built new interface for cw and push-to-talk [PTT] using 4N33s. CW works great. The PTT function seems to slow to react. Sending "CQ TEST DE ......" it pulls the FT-1000MP into transmit during the "TE; /archives//html/WriteLog/2003-06/msg00053.html (6,826 bytes)
2. [WriteLog] PTT timing (score: 1): Author: wa9als@starband.net (WA9ALS - John); Date: Sun Jun 8 18:04:44 2003; If you find a solution for that rig using optos, let us know. I tried several and could never get it to pull low enough to key the rig. A transistor switch will solve your problem if you can get over; /archives//html/WriteLog/2003-06/msg00055.html (7,659 bytes)
3. [WriteLog] PTT timing (score: 1): Author: rojomn@charter.net (rojomn); Date: Sun Jun 8 18:21:35 2003; You could use the OPTO to key a transistor switch. Hat would give the isolation and would key the radio.; /archives//html/WriteLog/2003-06/msg00056.html (8,723 bytes)
4. [WriteLog] PTT timing (score: 1): Author: NB1B@attbi.com (NB1B); Date: Mon Jun 9 06:14:28 2003; Rod Why the PTT line control? Why not let WL control the MP via the Com port line? The MP can be put into xmit by one line of the serial radio control cable. Use that feature, and no interface is nee; /archives//html/WriteLog/2003-06/msg00059.html (6,679 bytes)
5. [WriteLog] PTT timing (score: 1): Author: jpixton@shentel.net (Jerry Pixton); Date: Mon Jun 9 06:55:03 2003; Dennis, The problem is the FT1000mp has a software bug that cancels the PTT command after the first cw element so another PTT signal is needed for CW. Sad but so far true in all the 1000mp. The CAT c; /archives//html/WriteLog/2003-06/msg00060.html (7,712 bytes)
