For testing a 22 GHz LNB, you don’t necessarily need a laboratory-grade signal generator. The cheapest options are: If your goal is simply to confirm that your LNB and receiver…
TRIMBLE EXTERNAL CLOCKS: It depends on the specific Trimble device. For Trimble GPS-disciplined oscillators (GPSDOs) commonly used as 10 MHz frequency references: If you mean one of the surplus Trimble…
Yes. In fact, that’s the normal way to parameterize a custom Python block in GNU Radio. There are several ways to do it: 1. Pass a GNU Radio variable as…
For soldering the edge of a large piece of metal, the problem is its thermal mass: it conducts heat away faster than a normal soldering iron (typically 25–80 W) can…
The SETI League provides a set of dimensions to build a hydrogen horn. This has two components – the waveguide element at the far end which must have specific dimensions…
There are several maser transitions accessible to amateur radio astronomers, although 22.235 GHz water (Hâ‚‚O) is by far the most popular because the sources are strong and the equipment is…
Eduard Mol on one of the SARA meetings/online videos shows plot of W3ORS5 of water maser at 22 GHz. The plot shows LSR velocity km/s from -70 to -20 on…
Yes. On a Samsung Galaxy A34 you can exempt Microsoft Authenticator from Samsung’s battery restrictions, although it depends slightly on the One UI version. The setting you want is Unrestricted…
Before we all watched England successfully get through to the semi-finals of the FIFA world cup, this change in detection rate was seen on my PicoMuon detector. Other observers on…
Airspy HF+ Discovery and Airspy HF+ are closely related, but the HF+ Discovery is the improved second-generation design. For weak-signal work (including radio astronomy experiments) the Discovery is generally the…
