I was going to say the LDG-Z817 uses latching relays, so it saves battery draw versus other tuners that do not use latching relays. Depending on how you operate your mileage my vary.. I did however

The LDG Z-817 uses latching relays. Just wonder how little power is required between tunings. Alkaline versus zinc-carbon cells seem old fashioned. They are both "cheap" and poorly sealed. Suggest

With the amount of alkaline batteries that have leaked on me in the past few years (much more than in all years past) I would remove them if you know the tuner will not be used for a while.? Store

Ok guys. Thanks. How you are preventing from the leakage alkaline cells damage inside the tuner? I have very bad experiences with leaked AA alkaline cells and damaged Mizuho radios and other

Hi Petr NiMH cells would probably work, at first !? Their voltage is lower than AA alkalines, drops off even more with use, and are not recomended for that reason. Also the "shelf-life" (time to

if LDG say alkaline AA needed only then i would go with what they say, they know best, i use alkaline AA battieries and they have been in their for over 2 years and still going strong Mick SA4MDN

Hi all, merry xmas and enjoy relaxing event with relatives together. Could someone help please? Z-817 tuner arrived this year as xmas gift for my son. I am worrying how to power it from inside

Interesting comment on the bad ground, Joe. I didn't want to open the box, as it was brand new and didn't want to void the warranty. I like the idea of this compact all-in-one unit, though. There

Hi Ron. I believe the antenna has a 5:1 balun. Like I said, I always got great results with the Z817, as I confirm the swr on the radio's swr meter. When I use this new manual tuner, I don't get

Sorry I left out that info. The sound card interface is a Signalink, and the antenna is a Buddipole. I am also using a Z817 auto tuner. Have a great day!

Correction. I was mistaken that the 9219 is an L network. That means it isn't derived from the 16010.? ?My experience with MFJ chassis grounding through paint stands however. Joe n1khb? Sent from

I'm willing to venture that it's an mfj 16010 repackaged with extra stuff. I actually like the 16010. I did need to remove paint for the chassis ground connections before it would work right

I am sure the reason you got a better SWR reading at low levels and then high SWR with high power was what the watt/SWR meter could read.? SWR meters have diodes inside and act as a envelop detector

Hello all.? Wondering if anyone has used this product with the FT-817 or otherwise? It is an all-in-one QRP manual antenna tuner with watt/swr meter, dummy load,? and impedance matching network

You don't say what you're using for a sound card. I'm new myself particularly to FT8. I use an FT818 a signalink, a 10 mm antenna and my PC so you're only asking about the FT8 and making contact.

If you put the rig's display into "PO" position what does it show?? In my experience if you have output it will show on the display.? I suspect you either don't have your clock synced, or the audio

Try to make an SSB contact? Is your clock accurate (within 0.5 seconds)? If you can make an SSB contact,,your finals are likely OK, and if your clock is too far off you may be able to decode other

I have two of these radios. I do not have access to a watt meter at this time. If I am operating FT8, when the radio keys, the voltage shown on the LCD drops at least one volt. Would it be safe to

Put it in the System32 sub directory and then reboot your system so it will load the .dll 72/73, Robin W4IEN SKCC #7294

*Does anyone know if JTDX will work under Windows XP? I have a laptop that I want to use for portable use, but it's the old XP. I keep getting a error of Kernal32.dll missing and I can figure out
