The Yaesu FT-7900R can programmed with a computer via a 6-pin mini-DIN data port on the back of the rig. You can e-mail me at k1oc at .Ī Programming Cable for the Yaesu FT-7900R Using the Radio Shack Scanner Cable If anyone tries the new model, I would be interested in hearing of the results. I have no idea whether the new model also works for the applications described below. You can still (early 2012) sometimes find the 20-047 on closeout at some Radio Shack stores. Unfortunately, Radio Shack has discontinued this particularly cable and replaced it with a new model. Note that you do have to install the USB driver on the CD that comes with the cable. I also use it out of the box for controlling an ICOM IC-746 using Ham Radio Deluxe. I use it to program a Yaesu FT-7900R dual-band FM transceiver and an ICOM IC-T7H HT using adapters described below. Theoretically it can be used to program or computer-control any amateur radio that is programmable or controllable by TTL-level signals. I believe it uses an FTDI level converter chip.

The USB/TTL circuitry is in a small plastic case in the middle. It has a USB connector at one end and a 1/8" stereo mini-phone plug at the other. 20-047, about $25, originally used to program a PRO-83 scanner) is a simple USB-TTL level converter.
