October 2025 Tech Talk – JS8Call

KD5HIY 12 October, 2025

Join Us Saturday Morning, October 18 at the EOC * For an Introduction to JS8Call Advanced Text Communications via HF Radio Presented by Steve W5HK • FT8 is the only digital mode used by most hams, and its impact is legendary, but it is only the beginning.... • Digital modes in amateur radio include both voice and data. • There are two advanced modes today that allow moderate speed Texting on HF. • There are several trends taking place that indicate the hobby is moving away from voice on HF; Many hams today seem to prefer text over other modes. • We reviewed VarAC a few months ago. Today we will look at JS&Call, an offshoot of FT8. • VarAC, a purely text mode, is the virtual standard for EMCOM across the country where speed is an essential element. • JS8Call is very effective and uses less bandwidth than VarAC. Both have their place. • These modes allow reliable text communications out hundreds of miles running 5-10 watts and simple antennas.
