I have a Yaesu FT-817ND and recently purchased the Z-817H auto antenna tuner specifically for this radio. I just received a Toykyo Hy-Power Model HL-45B 45w Linear Power Amp. Can someone please show me the correct hookup diagram to hook all of these together? I also have an swr/wattmeter to put inline to the antenna.

The way to connect these is:

FT-817 to the HL-45B to the Z-817H to the antenna. An SWR meter is not needed as the FT-817 has a built-in SWR meter. If you want to add the external SWR meter it goes between the HL-45B and the Z-817H.

One issue is that the HL-45B and the Z-817H both connect to the FT-817 ACC connector. So, the HL-45B will have to be left unconnected and band switched from its front panel. The ALC feature is lost but I don't think this will be a problem as the 5 watts from the FT-817 is not enough to overdrive the HL-45B.

I have an FT-817 and have been considering getting the HL-45B to go with it.

You are asking for very expensive trouble.   From the FT-817 manual:

-------------------------
• Designed specifically for the Yaesu FT-817 QRP HF transceiver.
• Also works with any transceiver with maximum 20 watts power rating.
-------------------------

If you put the Z-817 at the output of the HL-45 (where it belongs, as the preceeding post says), you will be exceeding the Z-817's power rating.

If and when the Z-817 fails, it could cause a failure in the HL-45.

A 100-watt tuner (Z-11 Pro, or something similar) would work fine.

Charles, he has the Z-817H and not the Z-817 tuner. The difference is one will handle 20 watts and the other 75 watts.

Oops -- thanks for the correction.  I'm out of touch with new-product announcements!

Yes I never heard of the 817H before and had to look it up for the same reason. I used to have an 817 for my FT-817ND and it was only rated for 20 watts.
