Correct, I am using the DB-9 on the TNC.? I may flash them into standalone mode and test them individually with winlink on my laptop.

Side note, the 12/96 jumper is for the mini 6 connector. Are you using the DB9 connector on the TNC? Mat

Each one is tested in stand alone mode and then I flash them with the Pi firmware. Do the yellow and red leds come on at any time? You can flash them back to the stand alone mode and plug them into

"?I'm starting to wonder if it is some heavy QRM here from an external source to be honest." Have you tried listening to the the radio? How does it sound? You should be able to hear QRM.? Does the

I am using a cable from HamMadeParts.com that connects to the 6-pin data connector and terminates to a DB-9.? I got all three of my Pi9k6's from etsy.? The jumper is set to 1200 I thought of that

Also make sure you have the 1200/9600 jumper in the right place. This selects which pin on the 6 pin mini din is used for receive audio. Ideally Input peaks need to be above +-20000. 73, John

It's a Perl 5 script so doesn't need installing. In the terminal, type perl -v to see which version of perl, if any, you have installed. Docs are here:

Has anyone installed Yfktest contest logger on Bullseye or Buster? Looking for some guidance on if/how to do that. Thanks Steve AK0M

Based on that output, it seems the pi9k6 isn't hearing anything. I assume you're putting the audio out of your TM-V71A via the 6pin DATA jack so check the cabling from the radio to the TNC. If that

This is the output from the serial console connected to the pi USB port while still connected to the hat.? Hopefully this helps.? Also the radio is a TM-V71A

I am using 3 TNCs on this pi to control a VHF/UHF radio, a VHF radio, and an HF radio for my go box.? By lock I mean decode.? The I2C address in the pitnc_getparams command does not show the i2c

Hello KN6FOA, Two things here: 1. Are you really intending to use the PI9k6 TNC in I2C mode and not serial mode? This is NOT the default as the default is to use the Raspberry Pi's build-in

I am having issues with getting AX.25 to work correctly with PAT. I was finally able to build the firmware and flash the Arduino with the I2C settings for my pi9k6 TNCs.?I am using " sudo i2ckiss 1

David Thanks for helping. I have tried this before but I will give it a try again. Thanks Tom AE5NF

Is your Hifiberry HATT board recognized upon boot up? You *do* need to enable it via the /boot/config.txt file: https://www.hifiberry.com/docs/software/configuring-linux-3-18-x/ --David KI6ZHD

I would like to use a hifiberry dac+adc to run my SDR radio using Quisk, HAMLIB, FLDigi and WSJT-X software. I cannot get the Rpi4 to recognize the hifiberry. Has anyone got the hifiberry working as a

David, Those other Pi's are long gone, so there is no way I can do any further debugging. At present I've only got two Mac Mini's (one M1, one Intel) and this new RPi 400. This afternoon I hooked up

Ah.. I know BOINC and it's one of the more brutal sustained high CPU loading applications out there. If you turn OFF BOINC and your Rpi remains idle for days, do you see better uptime? If so, this

Here's where the MoPi2 hot-swap power supply hat really shines. It takes two 6-30VDC inputs, plus a charge input. Normally, your primary power goes into port 1 and your backup battery goes to port 2.
