I know you said you don't want to get into it, but I just wouldn't do that at all. And if you absolutely have to I'm not so sure half a wavelength is even going to help.

It's not for me it's for a friend in our radio club.

Has anybody used the KB9VBR copper J poles? Specifically the 2 m/ 440? If so what do you think of them? Any issues? Any positives?

Cool. Thanks man!

Does the wattage matter? I have some small resistors I could use, but they're only like quarter watt.

How did you build the calibration loads? I would like to do this myself.

But how are they going to enforce that? Meaning whenever I remember to change the address with them, that's the week I moved.

Good question. I haven't used mine on a single frequency yet. I'm scanning different bands on the antennas I have. In fact I never actually calibrated mine. I attached a 50 ohm dummy load to see what the SARK100 said the ohms were. Then I measured the dummy load with my multimeter, and they were...

What you sent here on worldwide DX works fine. Everything else I could find online elsewhere does not. So you should hang on to those files because they don't seem to be available anywhere else. Thanks again!

Thank you very much for that info. I won't be using this schematic right now at least. I purchased another one that works. However the manual in English is invaluable. I've been to several locations trying to download it. The links are broken or do not open up at all. One link goes to an...

I actually never received the return label, documented that with Amazon. So I still have the old one that doesn't work. I have since purchased a brand new one that works perfectly. So I may end up with this non-functioning one as well. They said it's too expensive to return to China. Already...

Start unplugging suspicious Electronics in your house one at a time to see if the noise stops. Or flip the breakers on the house one at a time. Or take a portable AM radio around through the house and outside the house it should pick up any stray RF. The closer you get to the source the louder...

I wrapped it up and sent it back. Buying another one.

Yeah. I figured the same thing. Just thought I'd try to in order to avoid shipping it back getting my money going somewhere else buying another. I am going to buy one of these. Very simple! I tried the Nano VNA. Got sick and tired of all the connection pieces and cables I had to buy. Didn't...

The build itself is all open source. And I've seen the directions for the build. I have not seen a schematic though. Seems like one would Exist by now.
