This varies from model to model, and can be difficult to determine without a manual. The next challenge is to determine how to wire the microphone or other jack from your transceiver to the PC or TNC. WM2U's Soundcard Interfacing might be a source of information for interfacing with older transceivers. See the HF Hardware Decoders page for examples of each. Fortunately there are many such schematics on the web. There are other soundcard devices that simply feed audio back and forth from the transceiver, but you would need to build your own keying circuit for your transceiver. These devices remove the restriction of only working on some modes - there's usually a wide variety of software vailable, and in this case, all the transmit keying and audio is also in a single box. There are several models such as the Tigertronics SignaLink. Without firmware updates, you are limited to the modes the TNC covers.įar and away the more popular way to go is via the soundcard. Unfortunately sometimes these TNCs are a bit limited in the modes they cover. There are several advantages - transmit keying, isolation and audio are all handled in a single box. There are still some folks that connect their transceivers to a Terminal Node Controller or TNC (such as the Kantronics KAM-XL).
