Adding bricks to point the Ptarmigan Array beyond the Zenith 21/12/2023
Admin
Today I decided to find out what happens when I take the array to point other side of Zenith (ie > 90 degrees). Will it just give same data as…

Working settings for meteor radio scatter detection at LRO during Geminid Meteor Shower 16/12/2023
These settings were very effective, and I should use them in future.

Stack of Mini-PCs at Lichfield Radio Observatory (LRO)
I am using one mini-PC for each radio astronomy experiment at LRO = these 2nd hand PCs are cheaply available on ebay.
Sudden Ionospheric Disturbance (SID) Monitors
SIDs are changes in the ionosphere total power detected when solar flare hits the atmosphere. The power is detected from Very Low Frequency (VLF) radio signals travelling through the ionosphere.…
Major problems with multiplying interferometer
I think I bit off more than I could chew by deciding to build a multiplying interferometer based on AD8302 amplitude phase comparator board from Amazon. I am very grateful…
First light on additive interferometer
Experiencing difficulties with my multiplying interferometer (which means it doesn’t work yet!), I am trying a simpler additive interferometer using 2 x Nooelec 1.4GHz dishes, SAWBird+ H1M LNAs at dishes,…
Determining the galactic rotation curve of the Milky successfully with my 1420MHz array
Galactic rotation curve from my data: Below shows exercise of picking points for curve above in my data: Compare my rotation curve above with typical Keplarian rotation curve (not from…
Interferometer test rig
My proposed test rig for interferometer, although I intend to change the splitter to power splitter. Andy
