Ron, A quick glance at BITXmap.com ( http://BITXmap.com ) shows there are more ZLs than you might think.? Although it looks like Christchurch would make you the first from the South Island.

The rig ships with a perfectly functional sketch installed.? I recommend you get it all put together and fully tested before trying any of the other sketches or modifications floating around.

I believe you are transmitting an audio tone through a SSB transmitter. If your freq dial is set to 7.074.000 and you are sending a 1khz audio tone you will actually be transmitting on 7.075.000 (i.e.

Never one to take the easy road, I thought I'd share my progress so far with building up my uBitx. I call it my "Franken-uBitx" because it is made up from a lot of different parts I had laying

Hello Dex, There doesn't seem to be many ZLs building the uBitx so wonder if we could link up? I am in Christchurch 03 3389021 Cheers Ron ZL3VX

What do you know! Mine is uglier than yours.

Rod ill give it a go.. vince n2aie

Ordered on March 14th and was delivered on 4-19-2018, 3 days after being notified by DHL. ?Now if the case would come I will be happy person. ?I need to download the construction manual, if I can

The parallel resonance helps us to a point, though an ideal inductor would generally be better. For example, if the inductor is self resonant at 14mhz, we'd see much more power out on 20m than we see

You will receive a message from PayPal with a tracking number when it ships. They are running 4 to 6 weeks behind. Marco - KG5PRT

Aha!!! Thanks. Didn’t realize it was parallel. Much appreciated. Learn something every day! Gordon

Good question. It's a parallel resonance:?? ? ??https://www.everythingrf.com/community/what-is-self-resonant-frequency

How is a series resonance 30,000 ohms? I’m kind of dumb, but I thought at series resonance , reactive components cancel and all that is left is the tiny ohmic resistance of the wire. What am I

Here's mine.? I made it from an old 9 volt flashlight.

Gordon: Very high, about 30 K. It actually helps us. Howard

That is a good question. In our application, the impedance is still high, it just becomes more capacitive then inductive. If you look at the impedance plot, the resonance is about 20 MHz, but the

Hi Doug, Agreed. I operate remotely from the Yukon as VY1AAA a lot... when on FT8, it generates Big pileups. Those people who understand how to use split in FT8 get through faster. Technique is

?I found some on digikey with a self resonaance 40 Mhz or higher.... probably does matter. At the self resonant point the series impeane will be very

Understood. I’m wanting to put transverters in my ubitx; would love to control the I/O switching, as well as have the display show the transverted frequency. So, these would not be signals that
