split mode will not transmit

DonE

When i go to split mode, B is TX but not key the 6400 , this is true on all bands.

Same issue here, remote

I gave up and use RIT -offset . It works locally with CW at least and afaik also SSB

I seem to have the same issue with my 6400 running 3.4.24. It is intermittent. Most often, it does not work, then once in a while, it works fine.

I fooled with it and think I see the pattern:

Split

Transmit on Slice B

Doesn't work

Close Slice B

Close Split

Transmit briefly on Slice A (i.e. hit PTT button)

Split

Transmit on Slice B

Works every time

EDIT: Basically, tap the PTT just before clicking Split and it works.

It's one of the 3.3 + Features, Sometimes you can make it work by toggling between modes.

This and the loss of persistence on RX antennas making the RX ports useless keeps us on 3.2.39 at the contest station...

Fingers Crossed for version 3.6.66

DonE

I am running 2.9.2 never had a problem until now

Trying to work today several expedition and it very annoying to open Split, close split, TX on A slice OK, open split, no TX on slice B, close split start over.

Takes several attempts to make it work.

Ver3.5.9

N5NHJ

Same here.

KD0RC

I had the problem on 3.4.24, but 3.5.9 seems to have resolved it for me. I'm running a plain 6400.

I will experiment with it to see if I can recreate the problem. In the meantime, I recommend submitting a help desk ticket.

I was able to recreate the issue. The same fix outlined before works - tap the PTT before selecting SPLIT.

To recreate the issue:
Open one slice
click SPLIT 
Press PTT - rig may or may not key up (i.e. go into transmit, but no RF out)
Click SPLIT to close second slice
Click SPLIT
Press PTT - rig will not key up

This is not a fix, just a workaround...

This is intermittent and you have to do it several times unless it works

Oh well, tried to call TX7L on 18mhz SSB today. Spent 15min + to try to make SPLIT work. It would not transmit in SPLIT mode, period! In the end, opened 2nd Slice, added 5khz to TX7L TX frequency and work them.

When DX is lonely and not far away, you can dance around and try to figure out how to transmit, but sometimes you have a small window and do not have time to play.

Flex, PLEASE FIX THAT ISSUE ASAP.
