Re: #ubitx-help Strong Audio Tones in and outside audio receive passband #ubitx-help
For anything this complicated, a few units will fail in the field, if only due to rough handling through the mails.toggle quoted messageShow quoted text
The uBitx count is now up in the thousands.
Most uBitx's just work as delivered, no offending tones.
We're still trying to figure out how it is that a handful of rigs are misbehaving, and how best to fix them.
The initial complaint of audio tones in the audio passband on a couple rigs would be distracting, but the rig might still be usable.
The 13khz tones that John mentions are outside the audio passband, easily filtered if they ever get as far as the headphones.

I’ve been following this post. What does this all mean for a beginner who is waiting on a uBitx? Is there a problem with original design? Are these strong audio tones noticeable or interfering with when using the ubitx straight away?
