Re: TNC-PI9K6 Firmware Download

VA3ZUK
 

Mat,

I assume this was done on windows with pitnc_setparams. I'm running Linux and am unable to find a `amd64` build of pitnc_setparams. I've attempted to put the TNC back on the raspberry pi but am unable to use it anymore. I can not find the original firmware to revert the changes.

Who is the developer of pitnc_setparms? Surely there is an appropriate place to find support for their product.

Thanks,
Ash

And you don't have to use NOOBS ... you can install synaptic on various Raspbian (and other Debian family) images.

I had to change the screw resolution to get it to show. 

try that. 

Re: Cannot currently show the desktop

Diane,

edit
/boot/config.txt
and add
framebuffer_width=1900
framebuffer_height=1024

without the hdmi connected you need to set a size suitable for your screen.

Ian..

Did you ssh from the host computer to the Pi before activating VNC?

Get your Raspbian Buster image

Use Etcher to install the image.

Since it's basically acting like an antenna, keeping the GPS as far away from the HDMI ports as possible would be helpful, and of course, don't plug any HDMI cables in.

If your Pi4 is in a case, you could try getting some adhesive copper foil and putting it on the part of the case near the HDMI ports. I'd be curious to know if that makes a difference, assuming that interference from the HDMI port is what's causing the sporadic GPS issues for you).

Re: GPS looses FIX when HDMI is in use...

HDMI puts out enough RF noise to block the sensitive input to the GPS, move the GPS away from the Pi and cables as far as possible or test it by taking everything outside for a stronger GPS satellite signal. I had this problem with a GPS disciplined oscillator putting out a strong signal and had to move the GPS antenna about 10 feet away.
