Hi Thomas, hope you’re well.
Just a short message to bring you up to date on the performance of the new equipment.
In a nutshell, it’s brought me back to my old faithful friend, the FT-817. I bought my FT-817 20 years ago and it’s served me flawlessly all these years. It’s not the best at everything but it’s a perfect QRP shack-in-the-box.
The TB Box makes the little Yaesu a pleasure to use. The tuner tunes my 43’ vertical and K6ARK end fed random wire from 80-10 for the vertical and 40-10 for the ef random wire.
The battery tray slips out to reveal 6 Panasonic 18650 cells. The battery life is exceptional even with the 817 set on 5 watts. I’m just now in the process of topping the batteries up.
Attached are a couple pics of my operating situation today….it was such a nice day out on the driveway. I have a telescopic pole attached to the RV and strung the 41’ of wire up. Also, a closeup of the battery tray and one of the cells.
I can whole heartedly recommend this piece of gear to supplement an FT-817/FT-817ND/FT-818ND.
Very cool! Thank you for sharing the update, Brent! I’ll admit that I like the “old school” simplicity of this power and trans match system.

Very nice Brent. I feel the same way about my IC-705. I use can use either the AH-705 or an Elecraft T1 for a tuner. It’s nice to work with things you like. BTW I also have a Begali Traveler (mine is blue). It is the paddle I use the most when out and about. Hope to work you in the future.
Thanks Scott, I think the IC-705 is going to be my next rig. My KX3 and PX3 sit idle, not because I don’t like them, but I really get a kick out of using things I’ve built. The Hendricks PFR3B and the Pentek TR-35 are fantastic QRP cw rigs that seem to be my go to rig. The PFR3B with the built in balanced liner tuner is so versatile. Recently I upgraded the Traveller finger pieces to aluminum and find that makes a world of difference for accuracy in sending…
The TB Box looks like a great idea for the FT817. I’d add one to my FT817 if I did not already have it in a PVC frame go box with LDG Z817 tuner, battery and AC supply.

Nice setup Ron
Thanks for sharing this. How long do you get in the battery pack, assuming 5W and usual transmitting:receiving?
Hi Bruce. I’m away right now and can’t recall. From memory, I’ve not been disappointed. When I return home shortly, I’ll get that estimate and publish it or perhaps email you.
