Failure on first use?

 

I received my new ZBitx last week and pulled it out for an initial operation today. Mostly checking out FT8, recriving signals and had answered a couple when suddenly the receiver started putting out noise and could not hear anything but the noise. ?Verified the antenna was good by hooking up another transceiver, checked and messed with the various options to no avail. ?Any thoughts on possible causes? ?I took some pics and videos and will reach out to HF Signals after the weekend unless anyone does have some suggestions. Definitely disappointed.
 

On its predecessor, the sBitx, the?codec would occasionally go out to lunch (usually on startup) and then you get zilch nada nothing.? ?There have been various improvements in the I2C connections, but the chip has been difficult.? ? I don't know if that is what is happening to you, but if it is, there is a decent chance it will work within a bit again.

And of course, there could always be a bad connection, too......the world of just-built radios is just like the world of "new cars" and "new houses" -- not everything is always perfect!

Russell,

Check your power supply (or batteries if using). ?Two of us from our club bought the zBitX at FDIM and bought batteries in the flea market. ?After about 15 minutes of just listening the screen flickered, went gray, and the radio shut down. ?We thought we had bought duds. ?But on getting home I used a stable power supply (and later with new 18650 batteries) it works well. ?Later we heard that the flea market seller was selling 8 year old batteries he had bought cheep as one of our group went back to exchange a defective charger.

Just hoping that is your problem.
