Radio comms hobby: Weather satellite and ISS pictures, shortwave radio signals, space news
Another post about interesting signals from space 🙂 The International Space Station (ISS) occasionally transmits SSTV (Slow Scan TV) images on a 2 metre band VHF frequency. I have received these images on previous occasions and I show one below as an example. But the ISS also has a 'cross-band repeater' on board, whereby licenced radio hams can transmit up to the ISS on a VHF frequency, and their signal is retransmitted in real-time back down to Earth on a UHF frequency. Occasionally, the astronauts on the ISS will also chat with the radio ham 🙂 I noted that the ISS was going to pass over my location at the ungodly hour of 3.10am last night. So I decided to see if I could contact another radio amateur via this repeater. I set up my equipment using a small 'walkie-talki' as the uplink transmitter and monitoring the UHF downlink frequency using my SDR dongle and software. Ideally, I should move my UHF yagi antenna to follow the ISS as it moves across the sky above me, but this was impossible, since I also had to use my walkie-talkie and monitor my laptop for received signals (I have to manually rotate/swing the antenna mast - I have no Az/El rotator).. So I pointed my antenna sort of mid-pass.... Anyway, as the ISS came over me, indeed I heard another radio ham who had also got out of bed like me! This was Liu Cheung in Hong-Kong, callsign VR2WAZ, and I attach a short audio recording of his signal that was being relayed by ISS 🙂 Unfortunately, although I called back, my signal was quite weak, but the ISS relayed it. You can hear Liu say "QRZ" which is a short code for "who was that?" so he heard my signal but the ISS was already at a low angle and moving northwards over China. (AN doesn't support mp3 files so I saved it as a blank mp4) VR2WAZ.mp4 BTW, for anyone not interested in space comms, it must be more exciting to watch paint dry... 🙂 -

Crime Foreign Man Damages ATM Outside Indian Restaurant in Pattaya After Card Is Swallowed
Haha that's it, what I did when it was my fault. Bali airport, big new shiny bank ATM display and you'd think they'd have someone to sort nearby. No got. Rang the number provided, and advised as after hours Friday, I would only be able to retrieve on Monday. The credit card was about to expire so I dug out the new one out and found an ATM nearby to use the correct debit card. -

New footage shows Brit strolling out of air crash.
@richard_smith237 and his little posse “I am not racist, but…….” All the while we are immigrants in Thailand ourselves. And they are the first to cry if they feel slighted by Thais not rolling out the red carpet. The irony.
