Data files from LRO-H2 created using draft SDRplay GNU Radio Software and SDRplay RSPduo SDR 21-23/10/2025
Unfortunately, these do not seem to be able to be processed in ezRA. GRC file used for data collection below (GNU Radio Companion File): https://www.astronomy.me.uk/wp-content/uploads/2025/10/ezColGR251018eA-AT201025@2240.zip Data Files created by above…
Compare specifications of SDRplay RSP1, RSP2, RSPDuo, HackRF, PlutoSDR, and USRP B210 USB Software-Defined Radios.
Compare RSP1 RSP2 RSPDuo HackRF PlutoSDR USRP. Here’s a practical, spec-level compare of the popular SDRs you named, with notes for radio astronomy / interferometry use. Device RX freq. range…
Test data from LRO-H2, using GNU Radio and RSPduo 16/10/2025
https://www.astronomy.me.uk/wp-content/uploads/2025/10/DSES251016_10.txt Not worked! This first attempt to generate GNU Radio Companion GRC script with SDRplay RSPduo SDR which creates data files in ezRA’s ezCol.py .txt format does not appear to…
SDRplay RSPduo and bias tee
Yes — the RSPduo does include a bias-tee on its Tuner 2 SMA port. (SDRplay) Here are some details and caveats:
Easy Radio Astronomy Software (ezRA)
LRO-H2 Radio Telescope (150cm Solar Cooker Dish)
SDRplay RSPduo Software-Defined Radio (SDR)
GNU Radio Companion GRC file used for test of alternative to ezCol with SDRplay RSPduo for data collection for later analysis by ezRA on LRO-H2 radio telescope 16/10/2025
I am just about to use the following file on the Solar Cooker Radio Telescope (LRO-H2) as part of a test of a system to collect data in ezCol .txt…
Using USRP B210 SDR with GNU Radio Win10 revised 14/10/2025
Collated document I have put together, which I think might tell people how to do this……no promises! I got it working once, but twice might be too much to ask!!…
First output from SDRplay RSPduo GNU Radio based on modified DSPIRA GRC using small handheld Moxon aerial on aerial input 1 of 2 — 15/10/2025
This will not be Milky Way as inside and Doppler shift on the 1420 MHz line too big – about 190 km/s (calculated from the difference in frequency on plot…
