Hi Ed,
I saw your previous email on the subject also. Keying the sequencer
with TX1 is fine, but by using an output from the sequencer to then key
the 5000A you have created a latch. Once the PTT input to the 5000A is
asserted, TX1 will never release, and if TX1 doesn't release, then the
sequencer keeps asserting PTT to the 5000A. I'm not sure why it worked
for you in earlier releases, but I wouldn't have expected it to.
Instead of keying the 5000A with the sequencer,enable and then set the
TX1 delay in the Antenna form. That value (in milliseconds) is how long
the 5000A delays transmitting after asserting TX1. When PTT is
released, the 5000A will stop transmitting that many milliseconds before
releasing TX1. Essentially, the 5000A becomes part of your sequencer.
I haven't used my V/U module for 2M EME yet (waiting for good weather to
get my antenna back up), but I do use it for 6M EME. I'm not currently
using an external sequencer. Instead I program the delays for TX1 and
TX2 to control the preamp and amplifier switching, respectively. With
this configuration I get conventional sequencer behavior. When going to
transmit the preamp switches out first, then the amp turns on and
finally the 5000A starts transmitting. When going to receive, the 5000A
stops transmitting first, then the amp switches off and finally the
preamp switches back in. I'll have an external sequencer soon, but this
is working fine for now.
Hope this helps.

Hi Gang:
Have a question on the TX1, TX2, TX3 with respect to the U/V upgrade
and 2.0.16?
Before I sent the 5000A back all worked with the EME set up 1.18.6 and
WSJT 7.
and the TX1 would work with my sequencer ARRL handbook with relay's
Now with the new SDR program and the mod U/V TX1 allows the sequencer
to activate but will not allow it to drop back to normal. The spectrum
screen on the SDR program has a band width of only the transmit and
nothing in the rest of the spectrum screen. If I turn power off on the
sequencer all goes normal.
Question did something change in the TX1-3 or did the SDR program
change this.
Any EME op that is using the Flex5000A U/V with 2.0.16 have any
problems?
