How to use Discovery Dish hydrogen line feed on LRO-H2 150cm Solar Cooker Radio Telescope Dish
Adapted from advice by Alex Pettit. Alex: The Illumination of the feed is determined by the dish<>feed spacing. For small dishes, beam forming choke rings consume too much area. The…
Detection of hydrogen on LRO-H2 at LRO using Brian Coleman’s handmade hydrogen line feed
This data was collected using ezCol (Ted Cline’s ezRA suite of software). The dish is sold as a solar cooker for use on camping trips. It makes an effective hydrogen…
Jason Burnfield’s Hydrogen Line Drift Scan Analysis Tutorial for Galaxies outside the Milky Way on YouTube

An USA school STEM project has launched UKRAA PicoMuon detector on a high altitude balloon. They noticed low detection level right up to just before the balloon burst at maximum height, when they saw a high spike in detection? Why might this be?
The observations from the balloon flight can be understood in terms of how muons are both produced and lost as cosmic radiation passes through the atmosphere. When high-energy cosmic rays…
At last! Brian Coleman hydrogen line feed mounted somewhere near focal point on LRO-H2 solar cooker radio telescope
The supports now can be altered in length to optimise focal position.

How to check data collection service is running/start service/stop service on UKRAA PicoMuon Detector
Check GetDataRawACM0 service is running sudo systemctl status PicoMuonACM0.service sudo systemctl start PicoMuonACM0.service sudo systemctl stop PicoMuonACM0.service sudo systemctl enable PicoMuonACM0.service sudo systemctl disable PicoMuonACM0.service . Screenshot below is the…
Sketch a practical 20 kHz tuning arrangement (variometer vs switched L/C vs active front-end) tailored to radio astronomy
At 20 kHz you’re really designing a resonant system, not just adding a tuner box. For your kind of radio astronomy / interferometry work, the most practical approach is a…
