Bill, Yes I have seen that, and have set the polling timing in Commander
to compensate.
Once set , I have had no further issues in the last 6 months with this
setup.
Also CAT is not used for Ptt, the standard comport is dedicated to that
via RTS, so keying is not
affected by VSPE. RTS needs to be disabled in VSPE source comport
properties and CAT RTS turned
off on TCXR for it to work properly without issue.
I don't consider stating method for tracking the TX frequency in SUB VFO
'off topic'.
We are talking about vfo's ?
It may help someone that experiences a swr standby switch fault with
this type of setup.
Ok on VFO names, yes SUB VFO takes the place of VFO B, and I should not
refer to VFO B again
regarding the FTDX101.

Adrian,
you are correct about the SUB VFO on those sort of Yaesu rigs, my
prior statement:
"Other rigs have MAIN and SUB receivers which are also used for SPLIT
mode. These rigs usually (always?) cannot transmit using SUB unless in
SPLIT or full-duplex mode."
covers those.
I should have said:
"I suppose MAIN and SUB means two independent receivers, whereas VFO A
and VFO B are just software concepts mapped onto a single receiver.
Transmit in SUB only happens in full-duplex satellite modes or SPLIT
mode, otherwise SUB is only a second receiver."
SUB should not be called VFO B, that is not correct and will confuse
users.
As for your other off topic comments:
VSPE in splitter mode is categorically not supported by either WSJT-X
or DX Lab Suite Commander. Don't do that! Commander has support for
sending tracking CAT commands to a second device like your SPE amp
using its secondary CAT device capability. Using VSPE in port
splitting mode will inevitably lead to CAT command collisions that
could potentially damage equipment, and I will pre-empt your probable
comment that it has never happened to you with the response "It
hasn't yet".

With RIG Split the FTDX101MP always use's SUB VFO for TX, and it is
easily selected for TX for other TXCR use besides wsjtx.
"Transmit in SUB only happens in full-duplex satellite modes,

the FTDX101 at least. SUB is designed to do all TXing when offsets
are used.
This is why I use commander software to allow the PC cat connected
SPE amp to CAT read the SUB VFO frequency,
as it needs to monitor TX frequency to set SPE ATU as needed before
keyup.
VSPE splitter allows wsjtx and commander to share the enhanced
comport source CAT virtual port with room for another 2
programs to share (4 total).
One receiver VFO can be assigned a A and B VFO profiles switchable
and for split operation,
whereas with two independent receivers, Main and SUB, the SUB VFO is
assigned the VFO B job,
but retains its SUB VFO name, but it could also be called VFO B.

Hi Mike and all,
You find "VFOs.txt" in the main hamlib directory that tries to
describe the abstraction.The differences are rig-dependent along with
rig mode.
It was exactly the contents of this file which has triggered my
question.
Life isn't simple....:-)
Oh yes ! You are right. But my question remains open: What is the
difference between a VFOx and a subVFO ? Is it simply a matter of
definition or is there a difference in the function too ?

Hi Claude,
some rigs like the IC-910 and IC-9700 have two separate receivers
MAIN and SUB, each have a VFO A and VFO B (used for SPLIT mode for
example). They also use SUB as a pseudo VFO B when used in
full-duplex mode for satellite operation.
Other rigs have MAIN and SUB receivers which are also used for SPLIT
mode. These rigs usually (always?) cannot transmit using SUB unless
in SPLIT or full-duplex mode.
VFO A and VFO B where present are mostly indistinguishable, although
there are exceptions to this as some rigs only transmit on VFO B and
that is only when in SPLIT mode, i.e. they have no VFO B receive
capability.
I suppose MAIN and SUB means two independent receivers, whereas VFO
A and VFO B are just software concepts mapped onto a single
receiver. Transmit in SUB only happens in full-duplex satellite
modes, otherwise SUB is only a second receiver.
MAIN and SUB can usually be exchanged just like VFO A and VFO B can.
