Wow! Absolutely amazing. I had no idea the stuff was going on. I need to get with the times. Gordon kx4z

I suspect common mode RF from the antenna especially if you are using an end fed even with low SWR. Try adding a counterpoise of 10-12 ft of wire connected to the shield of the antenna connector or

Hi all, My uBitx v6 cat control crash when transmit on FT8. Problem happens in 10m band, when the radio is transmitting, almost half way through 15 second tx interval, error msg pops up that "a usb

The processor has to generate the BCD depending on your dial frequency. With 3 lines from processor you can get 7 bands or with this chip 4 lines and 9 bands. In the older rigs of the 80s this was a

Gordon, That is the chip used in the adalm pluto. If you want a nice project look for the langstone project. Juan

Raj, How did you generate the bcd inputs? Juan

I used a BCD to decimal chip. See attached datasheet. Raj

So my usual reply to the concerns that this or that corporation is unfairly making a? profit from their expertise ..... (which reminds me of the joke about the mechanic who chastises the surgeon for

Amazing. That’s simply amazing. An entire radio on a chip with those capabilities. Thanks for providing that!! Gordonkx4z

Analog devices has become a bit of the dark lord of all things RF and analog. They have bought out everyone except the Si5351 and they sell them at exhorbitant

It is ok to buy wm8731seds either Ali... Or ebay. An year back I had them from mouser. You need not suspect every item of ali... . Regards Sarma vu3zmv

Hi, I use this board from amazon. Audio Injector Zero Sound Card for The Raspberry Pi https://a.co/d/i7hAkat Juan WP3DN

Wired the 4 outputs and change the band limits and now have 30m to 6m bandpass working. That should be enough to finish wiring the tx and see how the output looks. Later will check the free gpio to

Hi Kevin, I noted that the frequency is 7.075 MHz. However, I believe that the correct frequency for FT8 is 7.074 MHz. Try that and see if the QSOs are answered. I do not know why the power is

Hi guys!!! Today Im testing a band pass filter with the ad831 if at 70mhz. The band pass board that Im using covers the bands from 160m to 6m. It apparently works very well. Now to figure out a way

I plan to use a Radxa Zero 3W which has a slighly different pin layout.

But you don't sell the chips. I am building my interpretation of zBitx and would prefer to use a CODEC that is available.
