Tentec 1213 rig to soundcard isolation and hookup kit
The model 1213 kit allows the rear panel AUX I/O jack on the Orion and Orion II transceivers, the rear panel ACC 1 jack on the Omni VII and Jupiter transceivers, or the front panel ACCESSORY jack on the Pegasus to be directly connected to a typical PC sound card for digital mode operation. No intermediate interface between the transceiver and PC is required; simply connect the 1213 with provided cables to your rig and soundcard and use your favorite digital mode software with the interface and radio.
The 1213 is a sound card isolation device that utilizes a pair of 1:1 600 ohm transformers to prevent ground loops from introducing hum or distortion into your rig-to-PC connection.
This easy to construct kit requires only a few solder connections and the use of basic hand tools and can be built by someone with no prior kit building experience.
