Interfacce Soundcard

Le interfacce soundcard sono usate principalmente per isolare il PC dal transceiver. Questo riduce il rischio di loop di massa ,previene disturbi e runori sulla modulazione.Oltre all'isolamento dai segnali AF alcuni di questi dispositivi offrono funzioni varie come regolazione del livello , controllo del PTT , CW keying e inoltre l'interfaccia CAT.
I piu' recenti sviluppi ti permettono di interfacciarsi tramite la porta USB invece della seriale per il controllo delle funzioni.

SB-2000Mk2 USB Transceiver Interface

Interfaccia USB compatta con separazione galvanica fra apparato e computer. Cavi disponibili per Icom, Kenwood e Yaesu. CAT e FSK, commutazione PTT e manipolazione CW attraverso porte COM virtuali.

Yaesu SCU-17 CAT- and sound card interface with built-in sound card

Yaesu SCU-17 Interface

The Yaesu SCU-17 is an interface to run with digital operating modes for almost all current Yaesu transceivers. The SCU-17 works as a USB sound card, therefore only one USB cable is required between interface and computer. The interface isolates all signals galvanically to avoid potential ground loops. In doing so the audio-in and audio-out, PTT, FSK and CAT signals are transmitted. The key signals are seperated by Opto-isolators, the audio signals by coupling transformers.

Overview microHAM Sound card interfaces and station controllers

microKEYER-2R/2R+
Universal controller for two radios. The microHAM device with the most fucntions! Ideal for contest operation with two radios at the same time (SO2R) or for everybody who wishes to control two (even different) radios at the same time. Supports all modes: Phone, CW, digital modes. The microKEYER-2R+ has an internal sound card integrated, the microKEYER-2R uses the built-in sound card of your computer.

microKEYER-II
Controller with internal USB sound card. The microKEYER-II supports the flexible selection of the audio source (microphone, sound card) depending on mode. Ideal for users who wish to use all modes including phone, CW or digital modes, and who wish to have a separate high level sound card for digital modes. Useful for day to day operations as well for the contest, all modes.

USB-II
Controller which supports all basic functions like CAT, PTT and CW keying as well as audio from the computer sound card. Like all microHAM interfaces of course with galvanic isolation of all signals. Excellent price/performance ratio, regardless if used during the contest or for the daily operations with a computer log at home.

microHAM USB-3 USB-III Interface USB-III

Like USB-II, plus built-in sound card. Only one USB cable from interface to your computer, better sound quality. The computer soundcard remains free for other purposes, no more swaping cables when using the radio.

Other CAT interfaces

Besides the above mentioned sound and CAT interfaces we offer a few pure CAT interfaces, i.e. devices which allow only the control of the CAT functions by the computer.
