Scanners & Radios · Volume 1
Overview, Decision Graph, and How to Read This Series
Tour of every radio, scanner, and DMR hotspot in Jeff's lineup — license tiers, posture mapping, decision graphs, per-radio volume template, and how to navigate the 25-volume series
Contents
1. About this volume
This is the navigator for a 25-volume reference covering every radio, scanner, and DMR hotspot in Jeff’s lineup. The series consolidates into a single Scanners_and_Radios_Complete.html deliverable; this volume tells you how to read it, where to look for what, and how the per-radio volumes relate to the cross-cutting synthesis volumes that follow them.
Each owned radio, scanner, or hotspot gets its own volume (Vols 2-19) following a standard 8-section template — hardware tour, operating modes, programming workflow, codeplug backups, field use, tips, resources. Three cross-cutting synthesis volumes (Vols 20-22) cover DMR network architecture, the programming software landscape, and the frequency-planning / license envelope across all the radios in one place. A test-equipment volume (Vol 23) groups the bench instruments — Gigatronics signal generators, the MFJ CW gear, the vintage RCP-665 vacuum tube voltmeter. The WiPhone (Vol 24) is the radio-adjacent oddity that lives in the bench drawer because that’s where it ended up. The closeout (Vol 25) is a laminate-ready cheatsheet + A-Z glossary + canonical anchor index for sibling deep dives in the hub.
This volume is the page that gets opened first. The other 24 are reached from here.
The sibling project Antennas (in Hack Tools/) is the 33-volume antenna-side reference; every TX-capable radio in this series pairs with antenna recommendations there. Don’t re-derive antenna content here; cross-link to Antennas Vol 29 (Use-case Matrix) which has explicit per-radio antenna recommendations.
2. The lineup at a glance
The 22 owned items in the lineup, organized by category. Each row points to the volume that covers it in depth.

Total: 19 RF devices + 3 bench/test items + 1 radio-adjacent device = 23 entries, plus the three cross-cutting synthesis volumes (DMR network, programming software, frequency planning) for 25 volumes.
3. The decision graph — “I want to do X, which radio?”
Use this table when the question is “I want to do this, which radio?” The cross-link in the third column points to the volume that covers it in depth.
| Use case | First-choice radio (with antenna note) | Deep dive |
|---|---|---|
| Monitor local public safety (PD/FD/EMS) — P25 trunked | Uniden SDS100 (HT) or SDS200 (base) — outdoor discone for base | Vol 10, Vol 11 |
| Monitor airband (AM voice, 108-137 MHz) | Uniden SDS100 / SDS200 with discone; Tecsun PL-880 for AM-only listening | Vol 10, Vol 11, Vol 8 |
| Monitor marine VHF | Uniden SDS100 / SDS200; any Uniden scanner covers 156-162 MHz | Vol 10 |
| Monitor weather alerts (S.A.M.E. county-coded) | Midland WR120 — dedicated weather alerter; scanners can do WX but no S.A.M.E. alerting | Vol 9 |
| Operate amateur HF SSB (DX, contests, ragchew) | Xiegu X6100 standalone, or X6100 + XPA125B for 100 W out | Vol 6, Vol 7 |
| Operate amateur VHF/UHF FM (repeaters, simplex) | AnyTone D878UVII (best analog audio), Yaesu VX-8DR (rugged), Baofeng F8HP (cheap) | Vol 5, Vol 2, Vol 3 |
| Operate DMR (talkgroups, BrandMeister/TGIF) | AnyTone D878UVII direct to a repeater, or AnyTone + WPSD hotspot for any-talkgroup-anywhere | Vol 5, Vol 19, Vol 20 |
| Operate APRS (position beacons, messaging) | Yaesu VX-8DR (internal TNC + optional GPS module) | Vol 2 |
| Operate GMRS / family-channel UHF | Need a GMRS-certified radio (none in lineup); flagged as gap. Baofeng F8HP can TX into GMRS but is not Part 95 certified. | (gap) |
| Shortwave listening (SWL — broadcast, utility) | Tecsun PL-880 (premium portable); X6100 if you want SSB tuning + spectrum | Vol 8, Vol 6 |
| Test equipment / bench RX | Gigatronics 6060A/6062A as sig gen; SDS200 + spectrum mode as poor-man’s SA | Vol 23, Vol 11 |
| General wideband scanning | Uniden SDS100 / SDS200 with discone — covers HF (limited) through 1.3 GHz | Vol 10, Vol 11 |
| Field-day portable HF | Xiegu X6100 + Wolf River Coil + 30-50 W direct out (XPA125B too heavy for portable) | Vol 6 |
| Mobile DMR (vehicle) | AnyTone D878 on the belt, or BCD536HP for scanning while operating | Vol 5, Vol 12 |
| RF safety / EMC compliance check | Cross-link to Antennas Vol 31 (Regulatory & RF Safety) and Vol 27 (Spectrum Analyzers) | (Antennas) |
When two radios both fit a use case, the choice tilts on posture (handheld vs. mobile vs. base), audio quality (the AnyTone has noticeably better receive audio than the Baofeng F8HP), and feature depth (the SDS100 is the only handheld with TrueIQ baseband decoding for the latest digital trunked systems).
4. The license envelope
Jeff holds FCC Amateur Extra-class with full Part 97 privileges across all amateur bands HF through microwave, up to 1.5 kW PEP. That covers TX on every radio in Vols 2-7 and the two hotspots in Vols 18-19. For everything outside the amateur bands, the table below is the operating envelope. Cross-link to the deep treatment in Vol 22 (Frequency Planning & License Envelope) and the regulatory deep dive in Antennas Vol 31.
| Service | Authorization | TX legal? | RX legal? |
|---|---|---|---|
| Amateur HF/VHF/UHF/microwave (Part 97) | Amateur Extra (Jeff has) | Yes — all bands | Yes |
| GMRS (Part 95 §95E, 462/467 MHz) | $35 GMRS license (10 yr) | Need license + certified radio | Yes |
| FRS (Part 95 §95B, 462/467 MHz) | No license | Need FRS-certified radio | Yes |
| MURS (Part 95 §95J, 151-154 MHz) | No license | Need MURS-certified radio (≤2 W) | Yes |
| CB (Part 95 §95D, 26.965-27.405 MHz) | No license | Need CB-certified radio | Yes |
| Marine VHF (Part 80, 156-162 MHz) | License (on vessel) | Vessel + license | Yes |
| Aero VHF AM (Part 87, 118-137 MHz) | Aircraft station license | No (no TX) | Yes |
| Cellular (Part 22/24/27) | Carrier-issued | Carrier only | RX is legal — but ECPA §2511 prohibits intentional intercept of certain content |
| Land Mobile Radio (Part 90, various) | Site/business license | No (no TX) | Yes |
| Public safety encrypted (P25 Phase II + encryption) | Agency only | No | RX legal where unencrypted; decrypting is illegal even passively |
The asymmetry that matters: TX needs a license; RX (in most cases) does not. Scanners are RX-only and lawful across almost every frequency. Where it gets nuanced is the ECPA § 2511 carve-out for cellular and encrypted communications — see Vol 22 §5 (Part 22 cellular) for the boundary.
5. Categorization — radios, scanners, hotspots
Three categories of device in the lineup:
Radios (Vols 2-9) — TX-capable transceivers. Bound by licensing for TX. Each requires a specific license tier (Amateur for Vols 2-7, none for Vols 8 and 9 because they’re RX-only despite being categorized here for purposes of “ham bench”). The Yaesu VX-8DR, the Baofengs, the AnyTone, the Xiegu X6100 (and amplifier) are full transceivers. The Tecsun PL-880 and Midland WR120 are receive-only despite being “radio” devices conceptually.
Scanners (Vols 10-17) — Receive-only by hardware and by Part 15 certification. The Uniden lineup spans flagship (SDS100/SDS200) → mid (BCD536HP/BCD396XT) → legacy (BC246T/BC350A/BC355N/Homepatrol). The legacy Uniden lineup is on the bench partly for historical/sentimental reasons; the flagships are the daily drivers. Modern scanners decode trunked digital systems (P25 Phase II most common) and analog conventional; legacy scanners are analog-only.
Hotspots (Vols 18-19) — Specialized appliances that bridge a local low-power VHF/UHF DMR signal to the internet, allowing access to any BrandMeister/TGIF/W0CHP talkgroup from anywhere with internet. The SkyBridge Plus is the turnkey commercial appliance (BridgeCom Systems); the DIY WPSD hotspot is a Pi-based MMDVM build with a Nextion display, hand-assembled by Jeff. Both transmit at very low power (10-20 mW) on amateur 70cm or 2m frequencies. Hotspot operation requires an amateur license; coordinate with local repeater coordinators to avoid stomping on the local repeater output.
The duality matters: a Uniden SDS100 is a scanner (RX-only); an AnyTone D878 is a radio (TX-capable). A hotspot is neither — it’s an RF transport bridge from local VHF/UHF to the internet DMR network.
6. The per-radio volume template
Each radio, scanner, or hotspot volume (Vols 2-19) follows this 8-section template, so once you’ve read one you know how to read the others:
1. About this volume — overview, when this radio earns the bench slot,
posture (home/portable/mobile/handheld), license tier required for TX
2. Hardware tour — controls, display, ports, battery, size/weight, build quality
3. Operating modes — bands covered, modulations, simplex/duplex/digital
4. Programming workflow — channels, scan lists, talkgroups, CPS pipeline
(cross-link to Vol 21 for the software)
5. Codeplug backups — versioned snapshots with file paths into ./programs/
6. Field use — antenna pairing (cross-link to Hack Tools/Antennas Vol 29),
posture, common gotchas
7. Tips & tricks — non-obvious operations, hidden menus, firmware mods
8. Resources — manuals, vendor links, community forums
Cross-cutting volumes (Vols 20-22 and Vol 23, 24, 25) use adapted templates because they’re not single-device — Vol 20 (DMR Network Architecture) has its own section structure focused on networks rather than hardware; Vol 23 (Test Equipment) groups multiple instruments with a per-instrument sub-treatment; Vol 25 (closeout) is cheatsheets + glossary + anchor index.
7. Programming software landscape (preview)
A quick map of which software programs which radio. Vol 21 has the deep treatment.
| Software | Radios it programs | OS | Cost |
|---|---|---|---|
| ProScan (Uniden CPS) | Uniden SDS100, SDS200, BCD536HP, BCD396XT | Windows | Paid (license) |
| Sentinel (Uniden CPS) | Uniden BCD436HP / BCD536HP family | Windows | Free (Uniden) |
| FreeScan (Uniden CPS alternative) | Uniden BC246T, BC346XT, BCD396XT, etc. (older) | Windows | Free |
| AnyTone CPS (D878UVII) | AnyTone AT-D878UVII PLUS | Windows | Free (vendor) |
| CHIRP | Baofeng F8HP, UV-B5, Yaesu VX-8DR, dozens of others | Windows/Mac/Linux | Free (OSS) |
| RT Systems VX-8 Programmer | Yaesu VX-8DR (alternative to CHIRP) | Windows | Paid |
| wfView | Icom radios (none in this lineup currently) — CI-V control | Windows/Mac/Linux | Free (OSS) |
| Pi-Star / WPSD web UI | DIY WPSD hotspot | Browser-based | Free (OSS) |
| BridgeCom config tool | SkyBridge Plus | Browser-based | Free (with appliance) |
The notable patterns: Uniden flagship line consolidates around ProScan + Sentinel (Windows); CHIRP is the universal cross-vendor backup that handles almost every cheap dual-band HT including the Baofengs and (sub-optimally) the Yaesu; AnyTone DMR has its own vendor CPS because the codeplug structure (talkgroups + contacts + roaming + APRS in one bundle) is too complex for CHIRP to handle well.
8. Posture mapping
Each radio fits one or more postures. The “best” posture isn’t always the most-used — the AnyTone D878UVII is technically a handheld but spends most of its time docked to a desktop charger because that’s how Jeff uses it.
Home base / shack:
- Xiegu X6100 + XPA125B (the HF rig)
- Uniden SDS200 + outdoor discone (the daily-driver scanner)
- SkyBridge Plus + DIY WPSD hotspots (DMR network access)
- Tecsun PL-880 reading at the kitchen table (SWL)
- Midland WR120 (always-on weather alerter)
- Gigatronics signal generator + RCP-665 VTVM (bench)
Portable / field day:
- Xiegu X6100 + portable antenna (POTA, SOTA, parks)
- AnyTone D878UVII + Wolf River Coil setup (DMR on the road)
- Uniden SDS100 walking around (incident scanning)
- Tecsun PL-880 in the backpack (travel SWL)
Mobile / vehicle:
- Uniden BCD536HP under dash (mobile scanning)
- Uniden BC355N as a backup vehicle scanner (cheap, reliable)
- Baofeng F8HP in the glove box (ham emergency comms)
Handheld / EDC:
- AnyTone D878UVII on the belt (daily DMR)
- Baofeng F8HP or Yaesu VX-8DR as backup HT (depending on band/use)
- Uniden SDS100 for incident scanning (loud crowd / parade / event)
The bench-drawer items (Vol 24 WiPhone, Vol 23 test gear) don’t have an active posture — they live where they live until needed.
9. DMR network architecture (preview)
A 30-second framing of how the hotspots fit into the DMR world. Vol 20 has the deep treatment.
Three big networks carry the bulk of amateur DMR traffic: BrandMeister (the largest, ~140k registered users worldwide), TGIF Network (smaller, more community-driven, easier hotspot setup), and W0CHP-PiStar-Dash (WPSD) as both a network and a Pi-Star dashboard replacement that Jeff’s hotspot runs. Each network has thousands of talkgroups — virtual rooms where users hang out. Some are geographic (TG 3162 = Michigan), some are special-interest (TG 91 = Worldwide English chat), some are time-slot-restricted, some are PTT-triggered (only active when someone keys up).
Repeaters are infrastructure-grade DMR devices that hams within RF range can use directly. Hotspots are personal low-power DMR devices that bridge your HT’s RF signal to the internet — they exist because most hams aren’t within range of a local DMR repeater, and even when they are, the hotspot gives access to any talkgroup on any network without the repeater operator’s gatekeeping.
Jeff’s two hotspots (SkyBridge Plus + DIY WPSD) point at the same DMR networks but give two different deployment options: turnkey (SkyBridge) vs. tinker-friendly (WPSD). Both produce essentially the same on-air experience; the difference is in configuration depth and update cadence.
10. Antenna pairing reference (preview)
Don’t re-derive antenna content here — every TX-capable radio in this series has its antenna recommendations in Antennas Vol 29 (Use-case Matrix), which has 17 per-radio sections (including all the radios in this project’s Vols 2-19) with specific antenna types, BALUN/UNUN choices, feedline recommendations, and a 4-tier upgrade ladder per radio.
A quick high-traffic reference:
| Radio | First-pick antenna upgrade |
|---|---|
| Yaesu VX-8DR / Baofeng F8HP | Nagoya NA-771 38 cm whip (~$20-25, +6 dB on 2m, +3 dB on 70cm) |
| AnyTone D878UVII | Same NA-771; the D878 stock antenna is below average |
| Xiegu X6100 | EFHW + 49:1 UNUN (HF) or Wolf River Coil portable setup |
| Tecsun PL-880 | Stock telescopic for SWL; YouLoop active loop for indoor weak-signal |
| Uniden SDS100 (HT scanner) | Diamond SRH77CA dual-band whip or RH-771 clone |
| Uniden SDS200 (base scanner) | Discone (Diamond D-130J, Comet DS-150S) outdoors |
| BCD536HP (mobile) | NMO mag-mount dual-band |
| SkyBridge Plus / DIY WPSD | 70cm rubber duck (stock); or 70cm J-pole / Slim Jim for slightly more range |
The hotspot antenna case is unusual — you want low power into a low-gain antenna since the hotspot is in the same room as your HT; high gain would just create RF problems for nearby electronics.
11. Cheatsheet and closeout preview
Vol 25 is the closeout — laminate-ready cheatsheet cards (DMR talkgroup quick refs, programming-cable pinouts, frequency-band reference, license-class quick chart), an A-Z glossary of radio terms used across the series, and a canonical anchor index listing every cross-deep-dive anchor that sibling deep dives can link into.
Use it as the field reference card; use the rest of the series as the bench-side deep reference.
