I enjoy visiting local National Trust properties and am a keen gardener. I enjoy photography in general and have a photo gallery listed below

My first attempt at growing Streptocarpus from seed - seed from @dibleys nursery

@Juverein @jamjake01 Headed towards Lands End, going home??

[Paul Gulliver @ipgphotography]

@Aviation_Movies @jamjake01 They're just returning now 17.55z

[Paul Gulliver @ipgphotography]

@LBoergerding @ElbaSatGuy No - just interested in normal acars messaging - from all sources

[Paul Gulliver @ipgphotography]

@LBoergerding @ElbaSatGuy If you are close to the aircraft you get uplinks as well, they're within the same frequency band. I usually get around 20 to 30 uplink messages per day compared to many hundred downlink messages. Military uplinks often contain position reports so are useful

[Paul Gulliver @ipgphotography]

@thebaldgeek @auonsson From the feeds I have, 25E, 54w,vdl2 and Iridium, everything is normal, getting ini messages from USAF traffic on most formats. Who is complaining about what exactly? Those complaining should set up a receiver and feed you.

[Paul Gulliver @ipgphotography]

@cemaxecuter @ElbaSatGuy @AirframesIO @thebaldgeek Thanks that sounds good, I will try it later

[Paul Gulliver @ipgphotography]

@DefenceGeek Did you mention the KC-46's - possibly 7 in Prince Sultan AB, 4 went in Thursday, I believe there were already 3 there from the beginning of January

[Paul Gulliver @ipgphotography]

@thebaldgeek @cemaxecuter Are you sure? Yesterday when I was testing I put in a gain of 20 and didn't get anything, when I increased it to 30 it started working, not much difference between 40 and 50

[Paul Gulliver @ipgphotography]

@cemaxecuter @thebaldgeek Yeah using Airspy R2, I started with default gain, changed it in the hope of getting an improvement - I'll go back to default

[Paul Gulliver @ipgphotography]

@cemaxecuter @thebaldgeek This is the command line to run the sniffer
./iridium-sniffer -l -i soapy-0 --soapy-gain=50 | python3 -u /usr/src/iridium-toolkit/iridium-parser.py -o zmq

@cemaxecuter @thebaldgeek How do I find that now? I'm not very familiar with Linux so I need simple instructions - When I installed it I just followed the instruction on your site - Using Dragon Focal by the way - not the latest Dragon o/s

[Paul Gulliver @ipgphotography]

@thebaldgeek @cemaxecuter Optiplex i5-8500 16Gb RAM - it's the same computer I've been using for iridium for around 12 months now -

[Paul Gulliver @ipgphotography]

@cemaxecuter @thebaldgeek I just know it as Iridium toolkit as describe on the @thebaldgeek github page https://t.co/koHIXyYf0X I've had this running for around 4 years now - for acars - I also noticed the cpu usage is almost double for the sniffer against the toolkit

[Paul Gulliver @ipgphotography]

@thebaldgeek @cemaxecuter I thought I would join in the fun, got the new sniffer working without too much trouble but disappointed with the results - the q-max and ok_avg% figures are not looking good - both running on the same X86 system, Airspy R2, sniffer gain = 40 - any thoughts?

[Paul Gulliver @ipgphotography]

@DefenceGeek 59-1464 just got airborne from Souda, are the tankers coming home? - perhaps they just stopped off for coffee and a sandwich

[Paul Gulliver @ipgphotography]

@DefenceGeek Last tanker just airborne from EGUN:
LAGR 12 AE04FB 57-2605 possible just with VALKYRIE 09
