How to edit Ted Cline’s GNU Radio ezCol-style data collector to change the FFT
Admin
Answer: I think you mean edit my GNU Radio collector ? I do not easily have the hardware to test. I attach 3 images, so that you can edit it…
Processing drift scan using LRO-H5 radio telescope of M33 taken in June 2026 on 29/6/2026
This was single drift scan and was processed using Jaspn Burnfield’s procedure for extra-galactic hydrogen sources with his help. The results of this attempt are available in this Excel spreadsheet,…

What are beta emission rates at 37000 feet vs ground level?
At an altitude of about 37,000 feet (11.3 km), the environment contains much more secondary cosmic radiation than at ground level, but it’s important to distinguish between beta particles and…
What types of radiation cause radiation exposure to airplane staff?
Airline crew are exposed primarily to cosmic radiation rather than radiation from the aircraft itself. At cruising altitude, the atmosphere provides much less shielding than it does at ground level.…
Chip sets used in the NESDR SMARTee vs RTL-SDR V4
Here are the actual chipsets inside both devices, stripped down to the essentials: 📡 RTL-SDR Blog V4 Uses: 👉 So the V4 is basically: R828D + RTL2832U This combination is…
Radio observing M33 with small dishes
This involves looking to detect the 21-cm (1.42 GHz) neutral atomic hydrogen (HI) line. Mapping extragalactic hydrogen with a small backyard dish is incredibly challenging, but is possoble. It was…
