I don't have LPT on this computer. I have the RS-232 PTT in the K3 menu set to OFF OFF. The serial # is #1037. I am wondering if there was a change made in the pull up resistors as a little while ago I removed my PTT IN lead from my remote microbit box which was turned off and it cured the problem. I don't have time to pursue it any more now as I burned up a horrible amount of time today trying to figure it out. I don't have anything hooked to the ACC jack other than what I need for FSK RTTY. I will pursue it next week.

We had a problem like his with the DVK out of the computer during phone SS in Nov. I think Joe W0DB who operated from here had something plugged into PTT in for SO2R but I have to confirm that with him. More next week.

Thanks Dave!

Are you using PTT via RS-232 command? I have noticed an increasing number of K3 hang-ups here with that method, with the rig left in transmit, until I push another F-key. Finally, today, I had enough, and switched to PTT via LPT. There were no hangups during the two RTTY Roundup practices, and the final tail seems substantially shorter, and more consistent.

Subject: [Elecraft] K3 RTTY Delay on RX

I have a delay after I stop sending RTTY before going into RX. It is
just long enough to be annoying. I am using Writelog.
I have it on one K3 and not another. I am using version 4.51 on both K3's.

I have read and tried everything I can think of with no success.

Anyone know how to get it to drop out right away?

Thanks,

Ed W0SD
