The IRYS device lets you control Icom AH-4 compatible tuners (including LDG) from your Yaesu radio natively. This means the radio controls the tuner, indicates the tuning state on the screen, and does not require use of the key jack to do this. Benefits:

• Use your native "TUNE" button on the radio, see tuner status on the screen
• Remote-mount a tuner, control it from the radio
• Access the much wider range of available tuners for Icom radios with your Yaesu
• Retain the ability to use your remote keypad and an external tuner!
• Tuner is powered from the radio (like an Icom radio does, when supported by the tuner)

I designed this so that people at field day with Yaesu radios can use their voice keyer keypad and an external tuner at the same time. It also brings the extra benefit of being able to swap antennas and tuners with Icom users!

This has been tested with the following radios:

• Yaesu FT-450
• Yaesu FT-710
• Yaesu FT-891
• Yaesu FT-991A
• Yaesu FTDX10
• Yaesu FTDX101MP
• Vertex Standard VX-1700

It should work with any Yaesu radio that supports the FC-40 tuner (i.e. FT-857, FT-897, etc), but the above have been tested. It should also work with any tuner that implements the AH-4 tuner protocol, but the following have been tested:

• Icom AH-4, AH-730, AT-120
• LDG Z-100A, IT-100 (and friends) with the IC-100 cable
• LDG AT-100/200/600/1000 Pro-II with the IC-PAC cable
• MFJ-929

The device has an 8-pin Mini-DIN plug that interfaces with your Yaesu radio's TUNER/LIN jack, and provides a 4-pin Molex connector for connection to an Icom-compatible tuner.

If you have any questions, please contact me ahead of time and I'll be glad to provide more detail, instructions, etc.

Note that color and finish of the enclosure, pigtail, etc may vary from the photo.
