Effect of changing 5m of RG58 coaxial cable into LMR400 coaxial cable
The following picture shows the theoretical improvement from making this change.
Changing coaxial cable on Solar Cooker Radio Telescope at LRO 2/1/2025
My son and I have changed the coaxial cable on my 1.5m parabolic solar cooker radio telescope from 5m of RG58 coaxial cable to similar length of LMR400 coax and…
Changing over to using SDR# and IFAverage on both LRO-H1 and LRO-H2 radio telescopes 21/12/2024
Having now mapped the Milky Way successfully using the Ptarmigan Array (LRO-H1) radio telescope over the last year, it is clear that there are some issues with signal to noise…
