I’ve discovered following works with Spectrum Lab software on my Dell M6800 laptop: Plug audio cable into microphone socket on Dell M6800. Select line in rather than microphone when pop-up…
Table showing SWG sizes in imperial and metric to help choose brass tube sizes for making tuneable monopoles for cantennas
Here’s a clean SWG table from 16 down to 30. Diameters shown in inches and millimetres. SWG Inches mm 16 0.0640″ 1.626 mm 17 0.0560″ 1.422 mm 18 0.0480″ 1.219…
Paradar X-400 coaxial cable
I have just taken delivery of 5m run of Paradpr X-400. This is meant to be a cheaper alternative to LMR-400 cable, but with similar specifications. My initial impression is…
Building tuneable waveguide probe
Since you’re building a tuneable waveguide probe (I’m assuming 1420 MHz given your past adventures…), here’s a clean, mechanically stable way to do it without it turning into a wobbly…
What brass tube will snugly fit inside or outside 1/8 inch diameter brass tubing, for making a tuneable cantenna monopole probe?
Here are the standard brass tube sizes that will fit snugly either inside or outside 1/8-inch brass tubing: 📏 Basic Dimensions of 1/8″ Brass Tube So you want tubing whose…
My new theory of Quantum Gravity……and why it doesn’t work!
The Theory: I have been thinking about how quantum physics joins up to gravity. How about this? Quantum physics tells us you can’t know whether something is present with certainty,…
How does an FIR filter work in GNU Radio
An FIR filter (Finite Impulse Response filter) in GNU Radio works by applying a weighted sum of a finite number of input samples to produce each output sample. Let’s break…
How could I create the equivalent of the FM demodulator block in GNU Radio, if the block did not exist?
FM demodulation looks mysterious in GNU Radio because it’s one tidy block… but under the hood it’s actually very simple. FM is just information encoded as changes in instantaneous frequency.…
