Uniden SX507-2CKHS

Published · Researched 2026-09-21

2026 availability note: A 2019-era model still listed on Amazon in 2026 (ASIN B07KNY3DT3, Best Sellers Rank #3,313 in Portable FRS Two-Way Radios) — legacy stock, not a current-generation product. No US MSRP published; historical street ~$85/pair (2019). Current price UNVERIFIED — check the live listing before buying.

Version lineage (2023–2026)

• The SX507-2CKHS launched ~2018–2019 as the top of Uniden's SX walkie-talkie line (above the SX167/237/327/377).
• Hardware unchanged since launch; Uniden has not announced a successor as of 2026-09-20. The Amazon listing remains active with the same bullet set.
• Treat it as a legacy-but-available pick, not a current flagship.

Overview

The Uniden SX507-2CKHS is a 2-pack of floating, submersible FRS two-way radios with the richest feature set in Uniden's SX line: 22 channels, 142 privacy codes plus 142 Direct Call codes, an exclusive Group Mode that lets you "ring" one person by 4-letter nickname, NOAA weather scan with alerts, 10 call tones, vibrate alert, and VOX hands-free. It ships with a dual charging cradle, 6 AA NiMH batteries, and 2 hands-free earbuds — the most complete kit in the in-catalog radio set. Uniden rates it JIS7 (submersible 3 ft / 30 min) and it floats. The 50-mile range claim is the standard line-of-sight fiction; real-world is the same 0.5–2 miles as every FRS radio.

Key Specs

• Channels: 22 FRS + 142 privacy codes + 142 Direct Call codes; exclusive Group Mode (nickname direct call)
• Range claim: up to 50 mi ideal (line-of-sight; terrain-limited like all FRS)
• Waterproofing: JIS7 (submersible 3 ft / 30 min) per product description; floats; Amazon metadata says IP65 — rating conflict flagged, JIS7 is the manufacturer's stated cert
• Weather: NOAA weather scan + alerts
• Battery: 14 h on included 6× AA NiMH; dual charging cradle with USB adapter; also takes alkaline AAs
• Extras: 10 call tones, vibrate alert, VOX, 2 hands-free earbuds included
• Frequency: 462–467 MHz (FRS)
• Package weight: 1.8 lb (shipping, incl. cradle)

Pricing

• MSRP: not published (UNVERIFIED).
• Street: ~$85/pair historical (2019 barcodeindex figure). Current price UNVERIFIED — the Amazon listing was live on 2026-09-20 but the price block did not render in this pass; check the live listing.
• Legacy-stock pricing is volatile; do not pay more than the Motorola T600 H2O's $85–100 street for it.

In the Box

• 2× SX507 radios
• 2× belt clips
• 6× AA NiMH rechargeable batteries
• Dual charging cradle with USB adapter
• 2× hands-free earbuds
• Printed materials

Warranty

1-year limited warranty (Uniden standard for consumer radios — UNVERIFIED for this specific SKU; Uniden's consumer-radio warranty is 1 year per brand policy).

Support & Parts

Uniden US-based support. AA NiMH batteries and earbuds are standard replaceables; the cradle is the proprietary part — verify availability before buying legacy stock.

Community Verdict

The feature-rich legacy pick — Direct Call nicknames, the dual cradle, and included earbuds make it the most complete kit of the three in-catalog radios on paper. But it's a 2019 design at legacy-stock availability with an unverified current price and a 1-year warranty on old inventory. Buy it only if the live price undercuts the Motorola T600 H2O; otherwise the T600 is the better-supported waterproof pick.

Long-term durability & warranty-claim reality (enrichment, Sept 2026)

• What survives: The SX507's durability story is its continued listing — still ranked #3,313 in FRS radios on Amazon in 2026, which means units keep selling and (presumably) working. The AA-NiMH standard battery format is the longevity feature: when the included cells die, any AA works. The dual cradle is a robust desktop charger with fewer cable-loss failure modes than Y-cables.
• What wears/breaks: (1) NiMH AA cells — included cells are the wear item; 14 h new, decaying. (2) Legacy inventory risk — buying 2019-era stock in 2026 means batteries may have sat for years; test capacity on arrival. (3) Earbud cables — thin wired earbuds are consumables.
• Warranty-claim reality: 1-year Uniden warranty (brand policy); on legacy stock, the practical warranty is the retailer's return window. No widespread defect pattern found.

Version history — year by year (enrichment, Sept 2026)

• 2023: Legacy SKU, still listed; the SX line otherwise static.
• 2024: Same listing, same bullets; motoadventura-style deal posts show it moving at discount.
• 2025: Still listed on Amazon; no successor announced.
• 2026: Still listed (BSR #3,313 in FRS radios, Sept 2026); no successor announced. The radio equivalent of a greatest-hits album that never left the shelf.

Head-to-head vs closest rivals

• vs Motorola Talkabout T600 H2O ($85–100 street): the Motorola is IP67 with a water-activated flashlight, USB-C on newer revisions, a 2-year warranty, and live retail support; the Uniden counters with Direct Call nicknames, the dual cradle, and included earbuds. For water use the Motorola wins on rating clarity; for group coordination the Uniden's Direct Call is genuinely useful. Buy the Uniden only at a discount to the Motorola.
• vs Midland GXT1000VP4 (~$70 street): the Midland is the value land pick with the bigger channel set; the Uniden is the waterproof/floating pick of the two. Different jobs — see the T600 for the water flagship.
• Bottom line: the Uniden is the "most kit for the money" radio if the live price is right; verify price and battery freshness before committing.

Care & maintenance

• Battery freshness: test the included NiMH AAs on arrival — legacy stock may have degraded cells; replace with fresh low-self-discharge NiMH (Eneloop-class) if runtime is short.
• Post-water: rinse after saltwater use; dry the cradle contacts.
• Cradle: keep the charging contacts clean; the cradle is the proprietary part — don't lose it.
• Storage: remove batteries for off-season storage to prevent leakage.

Buying traps

• Legacy-stock batteries: 2019-era inventory in 2026 = potentially tired NiMH cells — factor a $15 battery replacement into the price.
• Rating confusion: Amazon metadata says IP65 while the product description claims JIS7 submersion + floating — the JIS7 claim is the manufacturer's; IP65 alone would not cover submersion. Don't rely on the IP65 line.
• The 50-mile claim: the biggest number of the three in-catalog radios and the least real — same 0.5–2 mile reality as all FRS.
• Price volatility: legacy listings swing; if it's priced above the T600 H2O's street, walk away.

Community Verdict — added voices (Sept 2026 enrichment)

• Amazon listing (live 2026): BSR #3,313 in Portable FRS Two-Way Radios — still selling seven years after launch, which is itself a durability signal.
