No, we didn’t re-invent the wheel, we just made a convenient, single board, isolated, digital interface that works for almost all of the digital modes on HF and VHF/UHF. Works with DIGIPAN, FLDIGI, MTTY, MMSSTV and most all other sound card programs! Work PSK-31, PSK-63, RTTY, SSTV, NBEMS, plus many other modes on your HF or VHF/UHF rig. Nothing new about this technology, it consists of two 600 ohm line transformers for audio input and output from your pc to your transceiver, and an opto-coupled push to talk circuit that works off of an RS-232 port on your computer.

This is the “DIY” (Do it yourself) version of our interface.

What you get:

Assembled and tested board assembly

Plastic case with holes drilled and countersunk for mounting the board

Plastic cover with mounting slots for convenient mounting wherever you wish

2 ea screws to attach the cover to the plastic case.

2 ea 2:56 screws and nuts to mount the pcb

1 ea wiring diagram

1 ea circuit board layout

• Transformer coupled audio eliminates ground loops and AC hum on your signal
• Opto Coupled push to talk circuit also eliminates ground loops and false triggering of your PTT lines.
• Very small size, only 2 1/16” x 1 3/8” x .625” high, can be incorporated inside of many radios, with only your RS-232 cable coming outside of the radio.
• Weighs less than 3 ounces
• High quality FR-4 double sided, solder masked, silk screened Printed Circuit Board
• Compatible with most modern ham radio transceivers.

These interfaces have been tested on many Kenwood , Icom, Yeasu, and other brand radios.

 Simply hook up per the enclosed wiring diagram and load your software, configure your com port, turn on the radio and have fun on your favorite digital mode!

 Board layout and transformer styles may vary.
