Thanks Bryan, I understand and my board is an affected one. While I’m not far from you, I am across the border so am a little reluctant to ship it. I may jump across the border and ship it from Sumas,

We are just pulling the caps.

Are you guys just removing the bad caps like we would, or are you replacing them with the correct ones? I can stand to be without my board for that long, so sending it back sounds like a good option t

If we send our boards back for repair, what's the likely turnaround time? FWIW, I'm just a couple hours south in Seattle.

The issue with large gain settings is you drive the DAC into clipping, which won’t damage anything but the waveform will be distorted. I’ll do some tests in the lab tomorrow and post results. Bryan K7

I share Jim's question and appreciate your response! However, it still leaves me reluctant to make any alterations, as everything (including 1200 Baud Packet) works perfectly. By everything, of course

Hi Jim, First off, if the GPS antenna connector is on the same side as the Mini DIN-6 Connectors your board is not affected. Many low bandwidth HF Programs may work but you will need to raise the leve

Apologies if this is a silly question, but how will the bug manifest itself? What applications would be affected and in what way are they affected. I haven’t pulled my board out of it’s case to judge

Thanks Bryan! In any case, the rework was useful - default alsamixer settings that are shipped with the n7nix repository now work out of the box... Ed

The output of the DAC is clean so the filter is unnecessary from that standpoint. There may be some value from an RFI standpoint but you would be better off with a Ferrite on the Radio Cable.

The output of the DAC is clean so there is no benefit from that standpoint. There may be some value in reducing RFI from the radio but I can’t prove that.

Is there any benefit putting the right value caps back in place rather than just removing them? Ed

Thanks for all the info that's been shared! Is there a way to identify the affected boards from the O/S? GUI or command line either one? Or, is it just every board with the SMA connector down at the e

This only affects Rev 6. The boards with the SMA next to the power connector. Bryan K7UDR

How do we check to see if our board is one of the affected boards?

Here is there info needed to address the problem: The Audio output has an RC Filter of 100ohms and 0.1uF for a -3dB frequency of 16kHz. The boards were stuffed with 10uF instead for a 160Hz cutoff. Th

Thanks for the update! Could this explain why my recent DRAWs board (2 weeks old) doesn't work at all with the default TM-V71A alsa settings that ship with your image ? I mean the `setalsa-tmv71a.sh`

We have discovered that a capacitor was installed in the audio filter chain that can prevent certain applications from functioning properly. We apologize that this was not detected before the boards w
