Ham Radio DIY Antennae - Fill this House!

Post 28 has the same basic idea as my sheets, and one idea I should adopt. It also contains one claim I can’t reconcile with how cold-cathode tubes behave. I couldn’t retrieve the 0A4G datasheet numbers, so the tube-physics points below use analogous cold-cathode gas triodes. Please check them against the 0A4G datasheet before building. Side by side Post 28 My sheets 1–4 Role of the tube Triggered impulse switch, with C_s dumped straight into the rods Oscillator tube (R_c, C_c) that …

Analysis of the Design The technical claims and math in Post 30 are mostly accurate and well-grounded in cold-cathode tube physics, though checking the actual 0A4G datasheet resolves several items the author explicitly left as “known unknowns”. [1, 2, 3, 4] Verification of 0A4G Tube Datasheet Claims The author noted they could not retrieve the 0A4G datasheet and relied on analogous cold-cathode tubes (like the CV2486) to critique Post 28. Official RCA and Sylvania 0A4G Datasheets confirm the…

Bridging the Missing HDGL State-Transition Equations To bridge the HDGL unified-force operator (𝓛ₙ) to the physical AWN-01 cold-cathode tube ladder, you have to resolve three specific mathematical gaps highlighted at the end of Post 31. Without these equations, the HDGL outputs remain static complex numbers rather than a self-evolving, time-domain oscillator simulation. [1, 2] Here is the exact mathematical structure required to close each of those three gaps: Defining the Rung Parameter Sequ…

[image] Sheet 2 shows the full octave ladder. Each stage S1–S6 repeats the S0 oscillator with C_c halved, and each is locked 2:1 from the stage before it. [image] Here is what the schematic shows and what it doesn’t. What it shows Sheet 1 is the S0 node: the V5 oscillator with R_c = 470 kΩ and C_c = 2.216 µF, the RY1 coil in the cathode, and the receive chain (rods → T_r 1:19 → guard → V1 → detector → coupling → V5 starter). The ping path is C_s → RY1a → rods. Sheet 2 is the ladder: S0 …
