:+1: I well remember the internal reactions when highlighting one of the LoRa 2014 HAB flights that went over the Bristol channel, s.west England, over The Channel and a long way down towards Marseille (tracked by HAB enthusiasts for >1Kkm IIRC) - sadly the wind took it on a slow arc away from s.ea…

(Blush) that was me. It went over the Britol channel because it was launched from Caerrphilly common, just North of Cardiff. A simple foil party balloon, PICAXE microcontroller and LoRa device. I was the only one able to track with LoRa (from my shed in Cardiff) there were at the time only about tw…

Sorry Stuart - you are dead right! Was looking for my variant of that picture to add to post…I remember the PICAXE… even have one lost spares box that I picked up shortly after off the back of that story… Now part of LoRa marketing folklore! :sunglasses: :beers:

The choice of PICAXE was as a result of my PICAXE in space exploits and experience. Whilst many were puzzled as to why a PICAXE was used for that HAB flight it was the obvious choice for me, there were no ‘Arduino’ libraries for LoRa at the time and neither was there a PICAXE one so I stuck with wha…

[image] bertrik: Fun, but not so useful if you theoretically reach > 100 km, while I’m still seeing occassional loss over a distance of 1.5km in a city. “Occasional loss” is the norm in radio communication, especially in shared spectrum. There are some useful similarities between ultra long …

Indeed and when I pitch LoRa to potential audiences I always call out Long Range as a ‘proxy’ for deeper penetration into absorbant environments - loss through double/triple glazing? Loss through old stone walls in castles/stately homes/national monuments? Penetration through concrete walls of nucle…

There’s a balloon flying right now over the north sea being tracked through TTN gateways: https://tracker.habhub.org/#!mt=roadmap&mz=11&qm=1_day&f=xttn&q=xttn Probably using my https://revspace.nl/TTNHABBridge “middleware” to relay data from TTN to the habhub webpage. The blue circle is the “radi…

What’s that icon at -1 meter? Its coordinates don’t match the last position in the upper left. [HAB] And it seems it’s DevAddr 2601149D: [Gateway traffic]

I have been watching several hits on Local (Bourne End & Cookham) community GW in the N.West corner W/N.West of London at >200km and that is nothing to the ones going to Durham & TyneValley, Anglesey & West side of South Wales at >400km and can see several over in N.Ireland at >600km! :slight_smile: …

The bright red line (to the south) is the path over ground the balloon has moved already, and the other red line (to the north) goes to the ‘target’, i.e. the estimated landing location, based on a weather model. Some balloons carry photo and/or video cameras, for those balloons people in a “chase t…

Ah, @cslorabox explained:

Can I occasionally transmit at SF11 / SF12 without ADR?
