X marks the spot. #XRIT and working on WX Sandwich Maker today. Auto mode. https://t.co/TCCJjmPZSQ1 day ago
Apparently yellow is not the perfect map overlay color... now you can choose your own. #XRIT https://t.co/Q4MiqbI5PU1 day ago
It might be cloudy and rainy here but i can find sun and warmth using MetOpC this morning. This nice crisp image collected with #XHRPT using the new @SDRPlay RSPdx https://t.co/1ti7NQNISm3 days ago
front side of the phased array. Only 4/7 antennas. Rest of blades should be here by the weekend. https://t.co/IeUGwRXIoC3 days ago
The simplest form of a beamforming network (boresight beam) 😊 is a @MiniCircuits ZFSZ-8-43. Happened to have one in my toolbox. #phasedarray #radar #rf #antenna https://t.co/Qair0bFjRa Categories

ISEE-3 (ICE) Spacecraft Detected
ISEE-3 (ICE) Spacecraft was detected today using a 1.2m dish at 2270.390831 MHz. The signal at this frequency was also simultaneously detected and confirmed by Paul over at UHF-Satcom. The detection was accomplished by integrating multiple FFTs with the spacecraft … Continue reading

Comet ISON
Comet ISON is getting closer. Here is an image I grabbed in the early morning hours before sunrise. This image was taken October 18th at the KESA Observatory in Colfax CA. I am in the process of imaging ISON again … Continue reading
Lunar Reconnaissance Orbiter
Here is a quick look at the Lunar Reconnaissance Orbiter (LRO) signal. Even though NASA is shutdown as part the US government shutdown, there is still a good signal coming from the LRO. I was doing a quick 1.2m dish … Continue reading
