Hi Michael, I’ve been away for a bit but I’m back in the lab. What you are seeing is the CODEC Turning on and the DC Bias charging up the coupling Cap. At this point yes you should see a sine wave. Th

Hi Jim, You bought the kit and haven’t received the backordered case, We’ve refunded the difference. Thanks, Bryan K7UDR

No Red LED is unhappy power supply/ Measure the 5V Rail, I have seen issues with Pi4. Bryan K7UDR

Thanks Steve! I’ve got one local but I’ll keep you as a backup Bryan

If I can borrow a 7000 I’m sure we can figure out what the issue is. We’ll pay freight both ways of course. Also, are you connecting via the Data or Accessory Connector? Anyone have a loaner? Bryan K7

Thanks Andrew, we’ll check it out. Bryan K7UDR

Hi Ruben, A month ago? Yes You can verify just by looking at the board with a magnifying glass and comparing to the photo. The yellow resistors will be marked 104 instead of 100. We’re figuring out ho

David, you are right! 100ohm Resistors we’re incorrectly Stuffed as 100k creating a 20dB attenuator. I should have caught it when we had the cap problem. With the new run, 8 Components were stuffed in

Hi David, I will look into this. The last run of DRAWS did not have any value changes in the audio section. You may have found another assembly error. Thanks, Bryan K7UDR

Yes Dave, The latest updates is cases have been modified for Pi3/4 and samples have been sent for approval. Thanks, Bryan K7UDR

Hi David, There should be no difference in Audio Input between the revisions. 6dB sounds suspiciously like the resistor settings. Run Basil’s Script and let us know. Bryan

A note on the Power Supply: DRAWS is designed for a nominal 12V Input. 9-15VDC is the recommended range. There is a 16V Tranzorb on the Input which provides over voltage and reverse protection (if fus

Fabien, You probably have one of the recall units with the cap problem. Return it for rework or refund, your choice. Thanks, Bryan K7UDR

Hi Mitch, It was buried in my office/house move. You no doubt have one of the units with the cap/TX Audio problem. I will fix and ship your unit tomorrow. I’d like to hear more about your potential ap

Drivers only look at ProductID which is 4 for DRAWS

We are just pulling the caps.

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
