Evidence-centre purpose: Allow a technically competent reader to reconstruct the model, understand every assumption and distinguish simulation, field reference and manufacturer-guide evidence.
Accepted Solver Foundation
The project’s native macOS NEC-4.2 baseline has passed its controlled validation and rollback requirements. Licensed NEC-4 source, solver binaries, protected examples and private installation information are never part of the public package.
Current Rybakov Studies
| Study | Purpose | Available evidence | Status |
|---|---|---|---|
| R000 | First SS25 impedance sweep | Safe model, manifest, raw output, CSV and JSON | Exploratory |
| R001A/B | 16.5 ft versus 33 ft radial-length sensitivity | Safe models, manifests, raw output, CSV and JSON | Exploratory sensitivity—not Bob replication |
| R002 | Nine-band full-SS25 elevation/azimuth patterns | Safe model, manifest, raw patterns, CSV, JSON and SVG graphics | Controlled exploratory simulation |
| R003A–D | MPAS guide SS25/SS17 geometries and one counterpoise | Safe models, raw patterns, evidence-anchored JSON and SVG graphics | Controlled exploratory simulation |

The following figures are controlled NEC-4 education graphics, not measured far-field product specifications. The two overview figures establish the band progression; the representative 40 m, 20 m and 10 m pairs show how the classic full-SS25 and MPAS guide geometries differ.

Outstanding Measurement Programme
- 4:1, HYBRID-MINI and HYBRID-MICRO two-port/load-dependent loss and thermal behaviour.
- URT1 tuning range, matched loss, memory repeatability and common-mode behaviour.
- M-COIL and M25-COIL inductance, Q, loss, tuning sensitivity, bandwidth and temperature in their specified SS17 and SS25 branches.
- Coax/choke characterization and feed-line-current mapping.
- Return-system comparisons for MPAS wire, Counterpoise Kit, DIY, FSR and Stinger.
- Three-deployment repeatability, bounded ground and alternating field-strength tests.
Correction Policy
Accepted results are not silently overwritten. A correction creates a new revision, identifies what changed and why, preserves the earlier record and states which customer guidance is affected.
Status: Evidence architecture complete; public downloads remain gated pending technical validation, rights review and Carl’s approval.
