Pullin’ my hair out: Making FLDigi/FLRig make nice with a Heath SB-1400/Yaesu FT-747GX?

Uhg.

So the FT-747GX uses TTL level logic — so I got an FTDI chip cable. The Heath SB-1400 (what I have) is an FT-747GX with Heath’s name slapped on it and better knobs.

SO I want rigcat control. I’ve beaten my head against it for an evening. First, I beat my head against FLDigi; I learnt me a “FLDigi should use flrig”. So I grab flrig. Flrig claims to support the FT-747GX.

When I attempt to configure FLrig to talk to the radio, my radio makes some fantastic noises that can be easily described as “having ones mind suction-cupped through a blender and presented /r/fifthworldproblems for a day” The radio otherwise works, just gets really jiggered around until you reboot it, toggle the VFO a few times and spin through the bands.

I’ve made my own parts for this. In the interest of completeness, here’s the layout of the pins:

Rig side
1	GND	BLK
2	SERIN	BRN
3	SEROUT	RED
4	PTT	ORG
5	AGC	YEL
6	NC	NC

FTDI side
Red wire	5V
Black wire	GND	BLK rig side.
White wire	RXD	RED rig side?
Green wire	TXD	BRN rig side?
Yellow wire	RTS	NC
Blue wire	CTS

Halp.
