Universal RX Data Mode Cable for Receivers Fitted with 6.35 mm Audio Output Jack



Universal RX Data Mode Cable for Receivers Fitted with 6.35 mm Audio Output Jack

If you have a receiver with 6.35 mm mono jack audio output (speaker or headphones) then this cable-interface is a simple way of getting into data modes with the minimum of outlay by using your receiver and any soundcard equipped computer. In effect, it enables you to connect your receiver directly to your PC and safely monitor a selection of data modes without risk of damaging your radio or the computer. No external power supply or any drivers are required. Components are of the highest quality and the unit underwent the stringent quality control and inspection standards. It is not recommended to use long data mode cables, therefore this cable is 100 cm long only. Please note that this cable does not provide CAT control, it’s made for data mode monitoring using your receiver and the computer.

The cable is fitted with a 3.5 mm stereo jack at the computer’s end (connects to the sound card input), and 6.35 mm jack at the receiver’s end (connects to the speaker or headphones output). Input and output audio signals from the receiver to the computer are supplied through 1:1 bidirectional audio transformer for proper isolation of the circuit. If you use a straight audio cable without this audio transformer you can easily damage your radio and/or computer!

We do not write data mode programs. We also cannot properly support software, only the author of that software can. There is a lot of data mode programs can be found on the Internet! Most of these are «freeware» or «shareware» and in many cases provide a level of performance beyond your wildest dreams!
