The operation of the tuner is done very conveniently by the push button on the tuner, with the IT-100 alternatively by the "Tune" button on the radio. A longer push starts a new tuning cycle, a short push switches to "bypass". With 2000 memories the tuners find once tuned frequencies very fast, for new frequencies the tuning takes max. 6 seconds. The tuners match a SWR from 10:1 (3:1 on 6m) and therefore a much wider tuning range than many other tuners. Two LEDs show the "SWR too high" error and the tuning process.

Both devices are connected with the supplied cable (35cm long) to the CAT (Yaesu) or Tuner (Icom) socket of the radio, which also supplies them with power. This reduces the required cabling to an absolute minimum.

The IT-100 tuner supports all Icom radios with a 4-pin tuner socket (i.e. IC-706Mk2G, IC-718, IC-746, IC-7400, IC-756Pro3 etc.). The size of the tuner is 17x17x4cm, the weight is 750g.
The YT-100 is intended for use with the Yaesu FT-100, FT-857 and FT-897. The tuner has a size of 20x9x4.6cm and has a free CAT socket on the rear, allowing you to connect radio and computer at the same time.
