just build on a linux laptop and plug in the dongle. You can run chrome and
open the web interface, and that works just well for most cases. I actually
prefer the terminal interface out in the field because you can see
everything right there in bold in bright sun.

For aircraft operating at or above FL180 (18,000 feet), you must be
equipped with a Mode S-transponder-based ADS-Btransmitter. For aircraft
operating below 18,000 feet and within U.S. airspace, you must be equipped
with either a Mode S transponder with Extended Squitter or a Universal
Access Transceiver (UAT).* Universal Access Transceiver (UAT) equipment* must
meet the performance requirements of TSO-C154c

Hello James! Figures you would be up to date with the latest and
greatest. ;-)
This is new to me. I haven’t used Raspberry Pi for projects before; just
Arduino projects. I’m beginning to appreciate how powerful the Raspberry
Pi is.
Anyway, looks like there is a much greater percentage of aircraft equipped
with ADS-B now, compared to 6 years ago. I’m receiving ADS-B 1090 data
from many aircraft, some over 100nm from me; wow!
What do you think, for rocket launch application, which of the frequencies
would be better to monitor, 978 or 1090 MHz?

Doesn't do Military for obvious reasons, but been using for years to see

airspeed
and GPS current pos.

I was at a ROC launch at the end of last year, perhaps it was ROCtober?
Anyway, someone at LCO asked what the altitude of a commercial aircraft
going over and someone called back the altitude. So, just wondering what
they were using. For the military aircraft part of the question, I asked
this because of FAR launches. If it’s something that I could use before
launching any rocket I had, I would. Even if it increases safety a little
bit, I would consider it worthwhile. There are times when there’s no
contrail and not much sound either.
The fact is, there have been times when aircraft pass over the range and
no one says anything until we see it as it is going away. Even at launches
with many people that may see incoming air traffic.
I’m not even close to suggesting anything that would interfere with
aircraft. Hum, actually, the opposite. :-)
And, I’ve been advocating a two-way communication between the far pads
and LCO for years now. Hey, it beats the LCO trying to get the attention
of people at the far pads using the PA and then trying to understand their
hand signals. And, I’ve checked, because I was curious if a simple baby
monitor could pick up and amplify aerial sound better than without any aid,
and it does.
So, both practical and maybe just a little curious too.

I heard several people mention an app that shows aircraft in the area
during a launch. I’m curious about the current state of his kind of
technology. Do small non-commercial aircraft and perhaps military aircraft
have transmitters can be seen on these apps?
What are people using now for this?
Also, I noticed that you can be at the far pads and hear aircraft in the
vicinity that are not heard at the LCO. There are monitors that are pretty
sensitive now and this might be a good way to have direct communication
with the far pads as well. Worth a try?
Thank you,
