I have had a similar problem with contest software from time to time (not
just Writelog). If you have some snap-on toroids, try putting one next to
your keyboard on the line that goes from the keyboard to the computer.
Sometimes it is a little sensitive where along the cable you put it. I have
seen toroids on various cables of contesters' computers, so I guess that you
and I aren't the only ones!

Hi All;
I am having RF issues when running CW, Writelog and the amp.  What is  
interesting is I don't have RF issues when running CW, the amp and
Here is what happens.  I hit an F-key on the computer  keyboard and the rig 
goes into a 'key down' mode meaning continuous  transmit, no cw.  One way to

cure this is to back off on the rig RF output  such that the amp output is
400 watts and then the cw starts again.  
This only happens when I work from the keyboard.  I do not have  problems 
when I work the vibroplex key on either rig.  So that means there  is
relative to the computer and rig(s) interface.
I have tested each rig/amp and on same band/freq/antenna.
Rigs are:
TS-950 SDX and TL-922A
TS-870S and TL-922A
Yet I don't have any issues when using TR........I can hear y'all saying  
then use TR.  My software choice is a function of the particular  contest.
