I would attempt to use my Arduino keyer, however when I switch over to straight key mode I still notice the delay, so an outboard keyer won¡¯t help.
I reniced the sbitx process several times, and went all the way down to -20 (maximum priority), with no change in the responsiveness.
I¡¯m also experiencing the issue with attempts at keyboard-sent CW putting sbitx into a cycling loop between TX and RX loop with no RF coming out. ?

If it was
me, I'd tie into the transmit relay coil, you only
need a few milliamps of current for an led. What
happens if the radio gets RF into it and locks up
the PI? It might not indicate that the radio is in
transmit when it really is. That and a time-out
timer on the transmitter should be done in hardware,
not software.
I wonder
how many here know that the version of Linux that is
being used is NOT a real time operating system and
will do little housekeeping jobs whenever it needs
to. I hope this doesn't cause operational problems
for the sBit.

Hi
All,
I am adding a simple PWR LED to indicate when
the PWR switch is turned on.? I am also looking
for a way to drive a single LED that activates
when the sBitx is in transmit mode.? The reason
I think it would be helpful is once the screen
saver activates, there is no way to determine if
the radio has a stuck PTT or something you might
want to know about.? I know Ashhar is extremely
busy but in a previous post, he suggested using
one of the two unused pins of the encoder.? I
don't think he means one of the two rotary but I
am confused what he meant.? So I am asking the
question to the group: if you were going to
drive an LED to indicate transmit, how would you
do it?
I am thinking once the tie-in location is
identified, writing/adding a define and
digitalWrite to turn on the LED is the task.? Of
course I am hoping for a single location for the
addition, perhaps in in the tx_process but that
a guess.? Any suggestions would be great.
Thanks in advance, Scott?
