Antenna switch 6-to-2 MK2 Classic manual

This is 6-to-2 (six-2-two) RF switch designed for SO2R operation. Version MK2 have got higher isolation and new hazard protection board. There is still First-Win switching and added BCD inputs. Unused ANT ports are connected to ground. Switch can handle more than 3 kW of the RF power. Do not forget to Hot Switch Protection.

Switch Control - Connection

- It is possible to use connectors A - IN 1-6, B - IN 1-6 for conventional control over 2x6 wires (+ GND). The switch is controlled by + DC voltage > 12 V
- You can also use the BCD inputs A - BCD IN and B - BCD IN
- The switch uses binary combinations for 1 to 6. Again + DC voltage
- The BCD control has a voltage range from 3 V to 15 V. It is therefore compatible with TTL logic
- If you use TTL logic, it is necessary to connect also voltage for relay control - terminal +12 at BCD. The recommended voltage is 13.8 V. It is possible to supply this voltage separately for the A and B part. If the jumper (+12V A/B | AB) is switched to the A/B position, each half of the switch needs its own voltage (+12V at BCD). In this case, the part not in use may be without power. In the AB position, only one power supply to one of the +12 at the BCD connector is needed.
- If the BCD control voltage is higher than +13 V (13 to 15 V DC), you can use only the BCD + GND wires. The voltage for the relay is derived from the BCD control voltage.

When you use device with Open Collector:
- You have to add Pull Up resistors 4k7, 0.25 W from + 12 V DC (12-15 V)
- Or smaller 1k when you use + 5 V for Pull Ups

Third party software FreqEZ

  FreqEZ is a Do-It-Yourself hardware/software project by Larry K8UT that provides highly configurable Band Decoding and Remote Antenna Selection. For amateurs who use N1MM+ and DXLab logging software, FreqEZ will leverage those programs TCP/UDP broadcasts for antenna switching. For other amateurs, FreqEZ can connect to the BCD band outputs available from most transceivers. The FreqEZ software and is freely available to all hams, and consists of a pair of programs that run on the Windows and Raspberry Pi Raspbian operating systems.
