As far as WINMOR and ARDOP areĬoncerned we always recommend (and the radio control code Modulation source, PTT mechanism, etc) if they want their mode to To have to use the correct radio programming (e.g. Rick Muething, KN6KB Author of ARDOP and WINMORīut modes that support radios with built in sound cards are going

This is a significant advantage in multi mode software such as Winlink Express and RMS Trimode. Operating Pactor or robust packet (e.g External TNCs) while providing support for sound card modes. This is particularly true for those injecting sound cards/sound card interfaces into the Mic jack of radios.ģ) Using the internal sound card of the radio eliminates having to swap cables or use external audio "muxes" or "mixers" when multiple mode support is desired. Typical sound cards and interfaces like the SignaLink range 100-250 ppm or higher especially on some specific sample rates.Ģ) The primary advantage of the integrated sound card is that there are significantly less problems with RF feedback since the internal sound card is integral to the radio and works with better shielding, filtering and at a more optimum level than using an external sound card or sound card interface. Most integrated sound cards show sample rate errors of < +/- 50 ppm. Contrary to what many believe sample rate errors are not easily "calibrated out" especially in wide band modes like WINMOR and ARDOP. Icom F8101 and I have found the following:ġ) Integrated sound cards generally have better sampling accuracy. Over many years I have tested many sound card interfaces (including several SignaLink's and RigBlaster Advantage's) along with the "integrated" sound cards in the following radios: TS-590, IC-7100, IC7200, IC-7300, IC-7600, and Yaesu FT991A.
