micro Banddecoder

Automatic band decoder with CW/PTT Interface and control of an antenna switch

The micro Band Decoder™ is a device which gathers information about working frequency from the radio's serial communication port or the radio's band data parallel port or the computer's parallel port. It uses this information to control devices such as Band Pass Filters, Antenna Switches, Stubs, PA etc. This device is an essential part of the station setup for every contester!
micro Band Decoder can listen to the communication between radio and computer and exacts needed frequency information. If the radio is not communicating with computer (computer is OFF or logging software not running), the decoder acquires the needed information on actual frequency itself. With micro Band Decoder you will never ever forget to switch something when changing bands! You'll be on the air with properly switched devices even if your computer locks up or freezes.

microHAM antenna switches

Remote controlled antenna switches for 6 or 10 antennas

The antenna switches by microHAM are weatherproof for mast mounting, but can be operated in the shack as well. The switches can be controlled by the "micoHAM band decoder" (see above, 5m cable included) or other band decoders. The PCB in the switches is a special HF design with striplines, using individual stubs for optimum SWR and lowest insertion losses. Unused antennas are grounded, when unit is powered off all antennas are grounded. The solid aluminum die cast chassis with 4mm wall thickness provides excellent protection against RF interference (class IP66). Normally all switches come with PL jack (female), N jacks are optionally available. Switches are available with 1-to-6, 2-to-6 or 1-to-10 configurations.
