Link isn't good.

Thanks Guru. I loaded your work on my uBitx V6 and everything works cool. Added features are helpful and interface is smooth with better color combo.

Re: Okay new quesetion

A SWR meter is all that is needed to adjust simple antennas. However the nano VNA makes it easy to see where the antenna is resonate. You can take them out to the antenna so you do not have to go to

Russ,
All true until you get high enough and it starts going down.
I'd describe it as higher the closer to 70 ohms (natural impedance for dipole).
Also at less than .25 lambda the impedance is lower

Re: ubitx v6 board only
How cheap was the 5A 14V smps supply used?
As many cheap units lack some or all filtering to save a penny.
You could also have strong local qrm, have you tried any other receiver with the same

As the antenna raised (or lowered) from ground . . . the impedance changes.
The closer to the ground . . .the lower the impedance. Higher from the ground . . . the greater impedance.

Re: uBitx v.4 build information
Evan,
Obrigado pelas imagens.
Consegui queimar mais IRF510, hoje a tarde.
Inclusive os condutores +B (13,8Vcc e +B PA Power).
Evan,
Thanks for the images. I managed to burn more IRF510, this

digital s-meter/power meter forubitx
While at home in lock_down i saw this Web site (Forum.arduino.cc/index?topic=403234.0)
about a adding a digital S-meter/power meter using a arduino board, it looked good project for my
cubit ver 5

Remember to go to usb for cw if you try to use leg the frequency will be off. There are lots of quirks and the tube video is misleading if you zero beat a am signal which is 6 khz wide you will

Re: Okay new quesetion

I built a 20/40 dipole and was really struggling getting the resonance points where I needed them to be using my radio and SWR meter. I finally ordered a nanovna and was able to dial it in quickly

Re: uBitx v.4 build information
Hi Evan
It was feeding the PA with 20Vdc, through a boost (step up converting 13.8Vdc to 20Vdc), therefore with a different power supply.
I noticed that I am not receiving any signal on JTDX (FT8) at

Re: uBitx v.4 build information
Rubens,
Suggestion, verify that the receive function works, then try the transmit function without the power to the PA connection. You should be able to verify the bias settings as being adjustable
