One of the tasks, we have to address the CQ WPX Contest, the reliable communication computer – Icom transceiver. Originally intended controller had occasional problems with the start of the communication between these devices. Since we use log N1MM DX cluster, Bandmap-in and RETUNE the specified frequency band or software, this is a very important element of the operator. There is a worse situation than the pile-up “frozen log”. For this reason, we conceived Icom CI-V interface.

Participation is in principle very simple bidirectional voltage converter with two transistors, and a few components as shown in Scheme. Photo shows our solution on a piece of universal circuit. The logs do not forget to activate the voltage at DTR.

Since I started regularly participate in the amateur race, separately for the first VHF, later in the club OM3RKP also VKV. Since gaining access to the TA to work in this area only, primarily contesting (CQWW, IARU HF, SSB Liga, Dippeth and other).
