How to use the z817 tuner from LDG with your Yaesu FT-818

[@ShooterReadyStandBy]

~6v to run the tuner. Pull the batteries, wire in a buck converter, and hook it to the radio power source?

[@temporarilyoffline]

that's the plan for a future video - already working on it and I don't think you'll even need the buck converter. Stay tuned. (Frankly, I don't know why LDG didn't do this in the first place)

That is incredible, I'm tryin to erase all the years of frustration of screw turning from my memory, I want my time back, I like it!

Nice!

I've said Ope and Y'all in the same sentence before. Everyone was confused.

[@temporarilyoffline]

Ope, Y'all better fix that up. Bless Your Heart!

Tuner relays = ASMR

100% Agreed!

Morning Steve.

Good Morning to you!

Cool tuner but it’s a shame they didn’t use metal insert for the screws since you need to open it rather frequently without a battery door. Personally, I would see if I could hack another power source from the available power wires.

[@temporarilyoffline]

Agreed. New power is on the list!

I had an LDG auto tuner (LDG-Z111 I think) but something happened to it; it smelled of burnt components. I now have a MFJ 969 Versa Tuner II--a roller inductor tuner that was given to me. I love the tuner but hardly ever use it since I no longer have my old Kenwood TS-430S and now have a Yaesu 991a with a built in tuner that will handle all my antennae since they are all nearly resonate.

This is the way!

[@DonzLockz]

I can't believe I bought something before you T.O. haha I love my kit, however, I find that the electronic screwdriver is not super torquey... is that a word?

[@temporarilyoffline]

I agree - I must be getting old. I thought I wouldn't stop using it, but it's not the tool I reach for first.

I know you don’t do a ton of 3D printing videos, but I would like to see a project to print a new case for the z817 that is smaller with rechargeable battery and has 2 bnc’s on the back. Seems like an ideal cheaper tuner option for QRP radios with no ATU. Either way, thanks for the video.

[@temporarilyoffline]

That's a great idea - what do you think of powering the tuner from the radio vs a battery pack?

[@Locksnut]

@temporarilyoffline Love my Z817 tuner. The batteries last a long time. Wished it had a clear access panel for easy changeout and to make sure the batteries aren't leaking!

[@temporarilyoffline]

Me too!

[@DaveW6OOD]

@@temporarilyoffline I’d like the idea of radio supplied power as an option but would still like a smaller rechargeable inside for wider compatibility. Something like a flat pack lipo.

[@temporarilyoffline]

Makes sense!

[@KeepEvery1Guessing]

There is 13.8V on that jack on the 818. You could see if it makes it to an unused pin on the jack on the tuner. Of course, 13.8 V ain't 6V,. The logic probably has a regulator to get 5 V (or maybe 3.3V), and that regulator might be happy to take 13.8 V (a 7805 would, but a 7805 wouldn't be happy with 6V, so that's probably not what it has). But the relays may run on 6V, and they or their drivers may not be happy with 13.8V. Current demand and the radio's sourcing capability would also have to be checked. I assume that these are latching relays so that they only draw power during search for a match, not while operating afterwards, since this tuner is intended for portable operation, further evidenced by the AA cells. Maybe you can explore when you fix the broken one.

[@temporarilyoffline]

That's the plan, stay tuned!

[@phillyedhrj]

Real life "sonic" screwdriver?

[@temporarilyoffline]

Pretty Close

I know I'm a freak and an outlier, but for the record, I read manuals. Recreationally. Sometimes for things I do not own.

[@temporarilyoffline]

An outlier among outliers!

Dem are some long rails bub.
