Does anyone have any experience with the MFJ 1279? Let me explain why I'm even asking...
I have a Yaesu FT-847 All band/All mode transceiver. Specially called a Sat/Data radio. What this translates to is that there are special data ports on the back, one for HF and one for VHF. The problem is that the cool 6 pin din plug is the VHF data port and that's what my ancient packet interface uses. I've rigged up a way to parallel off for the HF data port that I thought worked. (see with WSPR thread) However PSK isn't working at all and I believe it's the way the interface is working. What the 1279 does that would be an improvement for me is that it interfaces through the 8 pin mic plug. It also gives me the ability to plug the mic into the interface so I don't have to change a bunch of wires to switch modes. There are a bunch more things it does after that, but this is the feature that puts it ahead of all the other sound card interfaces for me. So, anyone? |
| I am using an ancient Buxcomm Rascal that is completely hardwired. And yes, HF just uses a 3.5mm stereo plug. I've wired a stereo plug in to try and make it a "dual mode" interface for my radio which I thought worked. Maybe I'll try again later this evening with WSPR to see if I can make it work again. |

I assume you were wiring it like the pic in this link.
Were you having trouble with audio or PTT? |

Here is a plan for building an interface for that rig.
