Re: PI + Packet radio + GPS

I have two TNC-Pi: v1 for the original Pi's, V2 for Pi3 - there doesn't seem to be a version for Pi4, and I haven't checked whether V2 would fit a Pi4 in a full case. For software, I use Xastir. It may be possible to send messages to individual callsigns, I haven't used that feature. The Adafruit ul...

Re: Raspberry Pi Zero W.....for a pub

Many years ago, a company was making devices attached to the optics: each shot was logged, as were bottle changes. This was long before microcontrollers and the Raspberry Pi. The idea was that the management could keep tabs on when and what was sold/dispensed. Of course, you would still have to keep...

Re: We're looking at introducing more swag - what would you like to see?

There's a guy somewhere on the forum asking if he should get his son a Pi for going to uni. He's going to need a key-ring, isn't he? Giving your son a bottle opener for the university may send the wrong message. I think an official Pi heatsink shaped into the Raspberry logo (along with a 3B+ to ins...

Re: GPS MODULE

The Adafruit Ultimate GPS (Hat or breakout board) also has a 1pps pin, which can be used to synchronise a NTP server, should you wish to build one.
Not required in all use cases, but useful if you want one.

Re: Red Artifacts on Video from HDMI

I had something similar: HDMI to dvi lead into a TV/monitor, screen would occasionally flash red intermittently, wiggling it made it better/worse, until I replaced the cable.

Try some other HDMI cables & see if the problem goes away.

It's possible to use an Adafruit Ultimate GPS, and feed the 1pps output into a GPIO pin.

Re: Amateur radio PPT function

I use APRS on Pi:
I currently use two methods for implementing TNCs, TNC-Pi (a hardware kit by John W2FS), and a USB soundcard. Software for the soundcard is direwolf, which gives you the option of using a GPIO pin for PTT.

Re: Record USB audio input

I'm using a GeneralPlus USB soundcard to input audio ax25 tones to Xastir, for APRS.

Rather than use soundmodem, I am using direwolf, which has the advantage of allowing PTT control via a GPIO pin.
Currently, receive works: I have yet to wire up a GPIO pin and feed audio output to the rig.
