So I've been trying unsuccessfully to interface a secondary GPS NMEA stream to my quad with Pixhawk installed.  Finally I just connected my terminal program directly to Pixhawk and started sending a single GGA message.Here is a sample message I've…

Art commented on Chris Anderson's blog post Cool Pixhawk-compatible long-distance directional radio
"@Hugo Chamberland  I don't really care that much one way or another.  Just communicate advantages of a unit clearly and support it with facts rather than emotions and conjecture.  900 Mhz is not widely accepted by who exactly?   (433MHz for Europe)…"

Art commented on Chris Anderson's blog post Cool Pixhawk-compatible long-distance directional radio
"You increased complexity of the system for no quantifiable gain.  Since it is touted as a multi-mile range solution I assume that intent was to improve range of communications.  Well let's just try to use math instead of colorful superlatives to see…"

Art commented on Chris Anderson's blog post Cool Pixhawk-compatible long-distance directional radio
"The technical data is pretty limited, but based on what I see and data available, I don't think it is a "beam shaping 'radio'" As well as the statement on their web site: "high gain beam and keeps it always pointed to the drone control station"…"

Art commented on CSG's blog post 433MHz Super Long Distance FHSS LoRa Wireless data modem with USB UART 5+ km range
"I looked at LoRa modems some time ago.  I think Semtech somewhat misrepresent their product.  Just like with any other data you have to compare apples to apples, and they make it as hard as possible.  Since max power output of Semtech modem is the…"

Art commented on Thomas J Coyle III's blog post US Forest Service Clarifies Drone Use
"Last time I checked US Forest Service didn't regulate airspace.  This would be enforceable if they had had FAA amend already existing regulations.  Other than that they can try to enforce the rules until the first lawsuit"

Art replied to Hugues's discussion What is the status of 3DR radios?
"As far as I know none of the telemetry radios on the RC/FPV/"Drone" market (clones or otherwise) had their designs licensed by FCC to operate in ISM band.  It doesn't mean that it is not compliant - most of them are of similar design and rely on the…"

Art replied to Hugues's discussion What is the status of 3DR radios?
"The statement: "The RFD900 is designed to be compliant with the following standards" tells me that they didn't obtain license from FCC for this radio as well.  They also say that :"The user is responsible for compliance with local regulations for…"

Art replied to Hugues's discussion What is the status of 3DR radios?
"HK, got the same hardware and plastic for the most part.  It is actually a better design since it doesn't rely on HM-TRP module but it is all done from the ground up.  I got the 433 radio from them and made it work on 915Mhz.  You pretty much have…"

Art commented on Jake Stew's blog post 915 MHz 3DR Radio Tuning With $7 SDR Spectrum Analyzer! Spectacular range boost!?
"Jake,  if your goal to have internal zen about your equipment reaching the state of perfection then it is definitely not a waste of time.  However if you are trying to improve your radio performance then your experiment failed.  Your original…"

"note the question mark

I'm so sorry to misquote you.  There is really no particular meaning to the combination of "!?"  There is a valid combination of "?!" called interrobang designed to convey exclamatory question, like in: "What were you…"

Art commented on Jake Stew's blog post 915 MHz 3DR Radio Tuning With $7 SDR Spectrum Analyzer! Spectacular range boost!?
"I confess I didn't read the whole thread but in what I read I didn't find any data about the "spectacular range boost"  Seems like an entertaining albeit rather pointless frequency analyzer exercise but I don't think it affects you radio performance…"

Art commented on Hugues's blog post How-To avoid sparks when connecting battery
"Capacitors can be viewed as current storage devices

With statements like that I can only conclude that it is time to take that EL101 again."

Art commented on Chris Anderson's blog post Latest on US vs. Trappy
"It was long coming and well deserved by him.  Not to side with FAA and current rules, which are antiquated for sure and FAA is a slow government behemoth that's not in a hurry to change, but you can not just go out and do whatever the heck you want…"

"@HeliStorm @SgtRic  Nothing you wrote contradicts my statement: " Shotguns don't shoot bullets"  Yes you can shoot slugs, you can even shoot razor blades, incinerating round and who knows what else.  But you can't shoot bullets. "
