The model 712 adapter cable (6ft in length) is a soundcard USBdevice that allows direct connection of the AUX I/O, ACC 1, or AUX1 jacks on the Omni VII, Orion/Orion II, Argonaut V and some Jupiter HF transceivers to an open USB port for digital mode use.

I just received and installed a model 712 Soundcard digital mode adapter cable. I would like to comment on it as to how good it is in
I did get this usb soundcard adapter cable to work on my older Jupiter, following the instructions on the install sheet, along with the help of the tentec yahoo groups forum which someone posted a ,jpg picture of the resistor to change to 33k. The only negative things I found are (1) .The cable length is too short. It is necessary in some hamshacks like mine to separate the desktop PC and the Radio by at least 3 feet in order not to have stray RF get into the PC, even with toroid clamp on donuts on all cables. So, could you please make the cable 5 foot long?
(2) The USB connector is molded right into the plastic glob, and will not fit into the restricted USB slots of my Desktop, an older 3Ghz model with
four USB ports closely spaced on the back of the enclosure. I had to use a USB extension cable to make the connection.
(3) The mike output that goes to the software (MIC) on the pc for waterfall or spectrum display has too high of an output to the mixer, and I have to be careful setting it
or I get too much audio into most of the popular digital mode software like fldigi and DM780. This is just an annoyance, and could be taken care of with custom software, which would make the unit not Plug and Play compatible unless it was certified by Microsoft or Apple. But the unit works as well as I expected it to, I would give it 4 stars on the standard rating system.

I have had mine for a couple of years and it works great with my Jupiter. I have used it with many modes, PSK, Contestia, Feld Hell, Olivia and others. The only problem is that it will not support JT65. If that would work it would be perfect.

I purchased one for my Omni VII and then later another for my Eagle. This is a easy plug-n-play device. It handles the audio TO and FROM the radio along with the PTT functions on one cable. The Windows XP or Vista computer recognizes the USB device when plugged in and the Windows Mixer and application software easily handles the level adjustments. I use it with HRD, MixW2, WSJT and WSPR very successfully.

I'm an old timer, 50 years on the air, but a novice at digital modes. I have been hesitate to get on digital because I have nobody near me to hold my hand. I wanted to give it a try with my new Eagle, so I ordered the Model 712.
My Eagle is an original pre-production engineering model and needed a simple modification before it would work. ALL production units already have this modification.
After I upgraded my Eagle to the level shipping to the field, it was Plug-n-play with the Model 712. Within minutes I was participating in an RTTY contest. Made me wish I had not waited so long.
Configuration: Dell Laditude D-620, WIN XP Pro, and fldigi software.
The bottom line is, the unit does what it is claimed to do. If you are a MAC or Linux user, you may want to purchase something else.

This product is a Windows ONLY h/w solution. It does not work on either Linux or OS X. On either of those OS the PTT line will be permanently set to ON when the device is recognized by the operating system.
