UHF Satcom 🇬🇧 📡 📻

A few more!

A few photos from @emfcamp - a great techie event! @AmsatUK @BATCOnline @UKGHZ some great GHz stuff going on, tele, narrow band, satellites, 122GHz, frequency references, test kit, lots of cobbeling of things, tonnes of tech chat and general pleasantness, highly recommended.

A GPS module, can't find a lot of info on it, maybe from an Iridium Yellowbrick tracker.

@Gammitin I digg that!

Update on my recent SBC project: x.com/i/status/20778…

M0EYT/P on station at EMF camp, I'll be active on QO100 tomorrow!

ELEKTRO-L 2 GGAK (SKL Instrument) data decoded from the raw L-Band downlink matching official sources :-)

@Gammitin Proper PATA / IDE ! A few Mb up to 500GB! About 75 in that box.

10x 160GB SATA drives, for £1.50 each, they're supposed to be tested and working, but we shall see. They'll be useful in old machines with a sata to IDE converters! 👍

@F4Htq Have you measured the PN? Quite interested to see if this can be a good LNB reference at 25/27MHz from a 10MHz source.

Sex is good, but have you tried to calibrate your si5351 with an offset of less than 0.1 PPM ?

Amazing to see this demo on a 48K spectrum, I really wouldnt have thought the hardware would be capable!

Sadece dahiler bunu 10 saniyede çözer. Sizce cevap nedir?

No, not the late 80s but yesterday, preparing to watch a film. HDMI to composite, into UHF TX then received on the old Trinitron. PAL plus analogue audio.

@SV1XV Brilliant find, thanks! Looks ideal for 934MHz CB!

Anyone have a data sheet for this block PA module. Gut feeling is cellular 900MHz. Ive had a dig around but not come up with anything usable.

You are all welcome to the party! Please connect, have some fun with today's optimizations and report your experience (especially the throughput at the bottom left). WEBSPY SDR: prog.airspy.com:33335 #airspy #sdrsharp #webspysdr

@lambdaprog This is brilliant! Good to tune your Band II!

Getting there, eventually. Self-hosted WEBSPY SDR from a RPi5 using an Airspy R2. You can try it: prog.airspy.com:33334

Well, my diy power sensor for HP436/437 etc. power is now working ok in the -40 dBm to -10 dBm region. I hope to get it working in the -70 dBm to -20 dBm range. More info: groups.io/g/HP-Agilent-K… #hp #diy #powermeter

@G7Jtt Brilliant! I upgraded my usual radome to a plastic milk bottle, its worked well so far ;-)

@uhf_satcom Still using mine complete with high spec radome, only difference now I'm not using a rocket lens instead I'm using an old BSkyB black LNB lens. Thanks Paul 👍

One of the original POTY feeds seen in the wild, sort of! Its GKQs ! Still in excellent condition. Its an early version with SMA and N mounting holes.

@G8XZD_TV I think the new layout altered the perspective, it seemed to be quite busy and some rows I only found after lunch, my usual zig-zag method failed. FRARS @ Wimborne will be great this year!

@uhf_satcom Nice. Did you feel the event was a lot smaller than normal?

A gift found at the Newbury radio rally! Multistandard plus NICAM, and the utter bonus, teletext! it also does the French Antiope system, brilliant!!

@maxime_manceau Good to see another fdm-duo in the wild!

Fielday preparation for saq 17,2 KHz this we 😉 #vlf
