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

Hi All, If we are affected by the error, will we be notified? I’ve had mine about a month. I’ve configured the software, but have not yet transmitted, everything works on receive. Getting antenna and

Good deal Bryan, thanks for the instructions. I’m going to try the piggyback. Always wanted to learn smd. I’ll practice on scrap. Have a good break. David

I just purchased one a week or so ago Bryan, I am wondering wether it was "corrected" before it was posted to me here in Australia. If not, I will source the correct components and repopulate the pcb.

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

Thanks Bryan! No rush, my old board will keep me busy. David

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

To run 1200 baud packet using the discrimintor on the TM-V71a edit setalsa-tmv71a.sh MODE_9600_ENABLE=true and run the script. Bryan should get back to you on that.

This morning I went ahead and measured and then jumped R20 with a wire and left R26 alone. I ran the setalsa-tmv71a.sh with the switch file in place. I ran measure_deviate.sh -f 1042 on first the left

#audio

I had a closer look at the boards. Everywhere there is a 101 on the old board, there is a 104 on the new board. Even on what must be audio in. Is this part of the revision?

"I use the 9600 bps connection even with 1200 baud data which just selects the Kenwood discriminator output (PR9 Output 9600 (bps)) ie. pin 4 on the mDin6 connector is selected by ALSA setting IN1." T

From page 83 of the Kenwood TM-V71a manual Select 1200 or 9600 bps for the data transfer rate, depending on your TNC. 1200 bps: Transmit data input (PKD) sensitivity is 40 mV p-p , input impedance is

Rcv, not rev. Thanks spellcheck.

Well, I must have done something to the first board during my cable fiasco a year ago. I’ve had a tm-v71a since the first of last summer, new-in-box until this morning. I set it up. This eliminates my

OK, I attached the wrong file. Sorry. Here is the showudrc for the powertune/single-Pi/single-sd card experiment.

Thanks Basil, “Things to try for more data points. 1. swap RPi SD cards 2. swap DRAWS hat” I’ll try these things. “One unit has a power-down switch? dtoverlay=gpio-shutdown,gpio_pin=6,gpio_pull=up” Co

David, Trying to understand differences between the two units you are using. Things to try for more data points. 1. swap RPi SD cards 2. swap DRAWS hat One unit has a power-down switch? dtoverlay=gpio

#audio

Thanks Bryan. I just tried new DRAWS with old Pi and same deal with needing to raise the gain. I've attached the two showudrc outputs. Host:husky is the one I have to turn up the gain. David

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
