Thank you Kyle, I'll give that a try.

Here's what I received from microham:
> How are you keying the radio if the DB15 cables don't come with a mic connector?
All microHAM DB15 cables include PTT - for the FT-1000(D) PTT is pin 1 of the 5 pin DIN PACKET plug.
> I am using a Yaesu FT-1000D, DGII and WSJT-X.
The Yaesu FT-1000(D) - as with all Yaesu transceivers prior to the FT-2000/FT-950 generation - supported digital modes (AFSK, Packet)
only in lower sideband. If you want to operate in USB you will need to make an adapter to connect audio/PTT to the mic jack or
the "PATCH" and PTT jacks on the rear of the rig. *IN ADDITION* you will need to disconnect the microphone and disable the speech
processor in the rig.
For the DB15-FT-1000D cable, the adapter will need to be a 5 pin *FEMALE* DIN with mic audio connected from pin 1 of the DIN to
pin 8 of a mic plug, pin 3 of the DIN connected to *both* pins 5 and 7 of the mic plug and pin 3 of the DIN connected to pin 6
of the mic plug. Alternatively, the 5 pin FEMALE DIN can be connected to two RCA plugs - pin 1 to the tip of an RCA plug
(PATCH), pin 5 to the tip of a second RCA plug (PTT) with the shields of both RCA plugs connected to pin 2 of the 5 pin FEMALE DIN.
Similar adapters will be required to use USB in all obsolete Yaesu transceivers. The specifics of the adapters will depend
on the DB15 cable assembly and transceiver.
I still have no idea what mode to put the radio in to decode and transmit. If WSJT-X requires me to be in USB to decode and transmit, and I don't want to
make up another cable, what mode should the radio be in to decode and allow me to transmit?
PKT puts the radio in PKT/LSB and RTTY puts the radio in RTTY/USB or RTTY/LSB.
I've been searching you tube and google for 2 days. I read the DGII setup with WSJT and I'm able to receive but still can't transmit.
UPDATE:
Since *all legacy Yaesu transceivers lack support* for audio based digital modes in USB and many software authors are too lazy to provide
for LSB operation, you are SOL without making an adapter cable to use the mic or "patch" inputs.
I've uninstalled all WSJT software. One digital mode I won't be using until I either upgrade my radio or make the adapter cable.
