Stryker 10 Meter Radio - Stryker SR-447HPC2 Slim and Powerful
Stryker SR-447HPC2 — The Compact 55+ Watt 10 Meter Radio That Talks Above Its Weight
The Stryker SR-447HPC2 is a compact 10 meter amateur mobile radio built for drivers and operators who need real transmit power in a chassis that actually fits. Rated at 55+ watts PEP on AM/FM, with a seven-color LED faceplate, digital echo, variable talkback, and a slim body that slides into places the full-size Strykers can't touch, the SR-447HPC2 has spent years as the go-to Stryker for overhead cubbies, tight dash cutouts, and drivers who don't want to give up the Stryker sound to save an inch.
Every SR-447HPC2 from CB Radio Supply ships with a 3-year Stryker factory warranty, free shipping in the lower 48, and the option to add our in-house 10 Meter Pro Tune and Alignment service before it leaves the bench.

Why Drivers Pick the SR-447HPC2
The SR-447HPC2 exists for one reason: a lot of trucks don't have room for a full-size radio. Overhead cubbies in a Kenworth T680, tight center dashes in a Freightliner Cascadia, factory radio cutouts in a Peterbilt 389, the narrow console real estate in a Volvo VNL — you can spec any of the big Stryker chassis you want, but if the radio doesn't fit, none of it matters. The 447HPC2 fits. And it fits without giving up the Stryker feature set.
- 55+ Watts PEP AM/FM. Manufacturer-rated at 55+ W. On the bench, after a Pro Tune, expect roughly 60 W PEP on tone and voice peaks in the 75–85 W range with a matched antenna and 13.8V supply — well above the 4W federal CB limit and enough to punch through skip and distance without a linear.
- Compact Chassis, Full-Size Feature Set. Even smaller than a Cobra 29 in width and height, but with digital echo, variable talkback, seven-color LED, and NB+ANL onboard. Nothing was stripped out to shrink it.
- Seven-Color LED with Auto Rotate. Cycle through backlight colors on demand or let it auto-rotate. Dimmer knocks it down to almost-off for night driving.
- Dual-Knob Digital Echo. Concentric echo volume and delay controls up front, no menu diving. Stryker's echo section is one of the reasons drivers keep coming back to this brand.
- Variable Talkback. Monitor your outgoing audio without a second radio. Cranks loud enough to hear over a cab.
- SWR Meter with Protection Shutdown. Built-in SWR meter plus a protection circuit that stops transmit if SWR climbs into damaging range. It's a small annoyance the day an antenna problem shows up — and a big win every other day.
- Standard 4-Pin Mic Jack. Drop-in compatible with existing Cobra and 4-pin Uniden microphones, plus every 4-pin CB/ham mic in our lineup. No proprietary connector to fight with.
Stryker Family Comparison: Which 10 Meter Fits Your Install?
CB Radio Supply carries the full Stryker 10 meter line. Here's how the SR-447HPC2 slots against the two radios most people cross-shop it against:

Truck Fitment: Where the SR-447HPC2 Mounts
The SR-447HPC2 is the Stryker to reach for when space is tight. It's the only Stryker that will drop into most factory overhead radio cubbies without fabrication.
| Truck | SR-447HPC2 fit | Notes |
|---|---|---|
| Kenworth (T680, W900) | Yes | Best-fit Stryker for T680 overhead cubby; W900 dash slot also works |
| Freightliner (Cascadia) | Yes | Center dash fits; verify depth clearance behind trim |
| Peterbilt (389, 579) | Yes | Factory radio cutout, overhead pocket, or DIN opening |
| Volvo (VNL) | Yes | Slim chassis handles the tight VNL cubby where a 497 won't |
| Mack (Anthem) | Yes | Standard bracket install |
| International (LT/RH) | Yes | Under-dash or DIN mount |
| Pickup / SUV / Jeep | Yes | Center console, seat bracket, or under-dash — one of the easiest Strykers to fit |
What You'll See in the Video Above
Before you decide, watch our in-depth SR-447HPC2 video above. Here's what we cover:
- Full unboxing of the current-production SR-447HPC2, including every accessory that ships in the box.
- Front-panel walkthrough showing Volume, Squelch, Mic Gain, RF Gain, Echo, Talkback, NB/ANL, and LED color/dimmer controls, so you know exactly where each function lives once the radio is installed.
- Rear-panel overview with the unique power pigtail connector, SO-239 antenna jack, external speaker jack, and firmware programming port.
- Live power test on the LP-1000A wattmeter — dead key low/high, tone output, and real voice PEP — so you can see how the SR-447HPC2 actually performs on the bench.
Power Output: What You'll Actually See on the Meter
Real-world power depends on your supply voltage, coax length, SWR, and whether the radio has been tuned. The SR-447HPC2 ships stock from Stryker. If you want it bench-tested, peaked, and aligned for maximum output and receive performance before it leaves the shop, add our 10 Meter Pro Tune and Alignment service ($50) at checkout.
After a proper Pro Tune, here's what a typical SR-447HPC2 will do on an LP-1000A digital wattmeter with a good 13.8V supply and a matched antenna:
- Low dead key: ~1.5 watts (excellent starting point for driving a linear)
- High dead key: ~8.5 watts
- Tone output (high): ~60+ watts PEP — matches the 55+ W manufacturer claim
- Voice peaks (high): ~80 watts on live audio during bench demonstration
The takeaway is simple: this thing talks hard for a compact radio. On voice peaks it's punching well above the "55 watt" spec-sheet number.
What's in the Box
- Stryker SR-447HPC2 10 meter radio
- Compact mounting bracket (slightly smaller than a typical radio bracket — don't lose it)
- Factory 4-pin dynamic microphone with coiled cord
- Stryker proprietary power pigtail with pre-tinned leads and inline 10A fuses
- Accessory bag: side screws, mic clip, bracket pads
- Owner's manual and warranty card
Power cord note: the SR-447HPC2 uses a proprietary Stryker pigtail plug — not a generic 3-pin or 6-pin cord. If yours goes missing, order a Stryker replacement. Do not improvise; the pinout is specific.
Controls Walkthrough
Volume + Squelch
Standard concentric layout. Volume on the outer, squelch on the inner. No surprises.
Mic Gain + RF Gain
Concentric control. Mic gain sets transmit audio level; RF gain sets receive sensitivity. Turn RF gain down in strong-signal environments to keep the receiver from being overwhelmed.
Digital Echo (VOL + DEL)
Concentric echo volume and delay controls. Stryker labels them VOL and DEL — functionally, it's the same as an aftermarket echo board. Small twist of delay + light echo gives the classic full-bodied Stryker sound.
Channel Selector + Band Switch
Encoder-style channel selector paired with a dedicated band switch. Standard 10 meter operation with band flexibility for operators who need it.
Talkback + RF Power
Dual-purpose concentric control. Strong talkback and adjustable RF power — set the power low if you plan to drive a linear amp later.
Mode Selector (AM / FM / PA)
Three-position mode switch. No SSB on this chassis — if you need SSB, look at the Stryker SR-955HPC+.
Noise Filtering (Off / NB / NB+ANL)
Three-position noise filter switch. NB alone handles pulsed ignition noise; NB+ANL adds analog noise limiting for more aggressive filtering. On receive, the SR-447HPC2 has a reputation for being a genuinely good listener.
LED Color + Dimmer
Seven-color backlight, cycle on demand or set to auto-rotate. Dimmer knocks the display down to nearly off for night driving.
Rear Connections
- Power pigtail port for the proprietary Stryker cord
- SO-239 antenna jack — pair with the Stryker SR-A10 for a matched install, or a SR-A10MM magnet mount for temporary use
- External speaker jack
- Programming port — firmware only (this chassis has no frequency counter display, so no custom handle/callsign programming like on the 655 or 955)
Recommended Accessories
The SR-447HPC2's stock mic will get you on the air, but it's a starter mic — the kind of unit you'd expect from an entry Cobra or Uniden. Customers who care about how their voice sounds nearly always upgrade. Here's what our install techs pair with this radio:
- DRX-6560 4-pin noise-cancelling dynamic microphone — direct plug-in, single biggest upgrade you can make
- Astatic 636L noise-cancelling mic — classic 4-pin choice
- Stryker SR-A10 antenna — matched pairing, 10,000W rated whip, 2-year antenna warranty
- Gear Keeper RT4 retractable mic keeper — keeps the mic off the floor when you're not on channel
Licensing: You Need a Ham License
The Stryker SR-447HPC2 is a 10 meter amateur radio — not a Part 95 CB. Transmitting on the 10 meter band (28.000–29.700 MHz) is regulated by the FCC and requires at least a Technician-class amateur radio license. If you don't already hold a license, start at ARRL's Getting Licensed guide — the Technician exam is 35 multiple-choice questions and study time is measured in evenings, not weeks.
Where to Buy the Stryker SR-447HPC2
You're already there. CB Radio Supply stocks the Stryker SR-447HPC2, ships direct from Indiana, and offers optional Pro Tune & Alignment on our bench before the radio ever leaves the shop. Every SR-447HPC2 ships with the full 3-year Stryker factory warranty and our US-based support.

Stryker SR-447HPC2 FAQ
How much power does the Stryker SR-447HPC2 put out?
Manufacturer-rated at 55+ watts PEP on AM/FM. After a proper Pro Tune and Alignment, expect roughly 8.5 W dead key on high, 60+ W PEP on tone, and ~80 W voice peaks on live audio with a matched antenna and 13.8V supply. Low dead key is around 1.5 W, which is a great starting point if you plan to drive a linear amplifier later.
Does the Stryker SR-447HPC2 have SSB?
No. The SR-447HPC2 is AM / FM / PA only. If you need SSB (single sideband), look at the Stryker SR-955HPC+ (AM/FM/SSB, 100W).
Does the SR-447HPC2 have a NOAA weather radio?
No. NOAA weather channels aren't built into the SR-447HPC2. If you drive through tornado country or want weather alerts inside your radio, the Stryker SR-655HPC+ adds NOAA weather in a short chassis with the same 100W class output.
What's the difference between the SR-447HPC2 and the SR-497HPC?
Same Stryker sound quality, different physical size and power tier. The SR-447HPC2 is a compact chassis (6.25" wide, 1.88" tall) rated for 55+ W PEP — designed for tight overhead cubbies and older trucks with limited dash space. The SR-497HPC is a full-size chassis (7-7/8" wide, 2-3/8" tall) rated for 100+ W PEP — nearly double the peak power, six IRF-520 finals, larger faceplate with dual echo. If you have the room and want maximum audio and reach, go 497. If space is tight or you want the entry Stryker price, go 447HPC2.
Will the SR-447HPC2 fit in an overhead truck cubby?
Yes — this is the Stryker built for that install. The compact chassis (6.25"W × 1.88"H × 8.25"D) fits Kenworth T680 overhead pockets, Volvo VNL cubbies, and other tight factory spaces where the full-size SR-497HPC won't clear. Plan for 10" total depth once you account for controls to heatsink.
Do I need a license to operate the SR-447HPC2?
Yes. The 10 meter band (28.000–29.700 MHz) is regulated by the FCC and requires at least a Technician-class amateur radio license. Operating without one is illegal. Study materials and exam sessions are at arrl.org/getting-licensed.
What microphone should I use with the SR-447HPC2?
The stock 4-pin dynamic mic will get you on the air, but it's a basic starter unit. For clean noise-cancelling audio, pair the radio with the DRX-6560 4-pin noise-cancelling dynamic microphone — direct plug-in, no adapter, no rewiring. The Astatic 636L is another popular 4-pin choice.
What antenna should I pair with the SR-447HPC2?
For a matched Stryker install, use the Stryker SR-A10 — 10,000W rated whip with a 2-year Stryker guarantee. For a temporary or non-drilled install, look at the SR-A10MM magnet mount. Tune to lowest SWR on your operating frequency and the radio's built-in SWR protection will act as a backstop.
Does the SR-447HPC2 have SWR protection?
Yes. There's a built-in SWR meter and a protection circuit that stops transmit if SWR climbs into damaging range. It can be annoying the day an antenna problem shows up — and it's the reason a radio survives it.
What's included with the Stryker SR-447HPC2?
The radio, a compact mounting bracket, a factory 4-pin dynamic microphone with coiled cord, a Stryker proprietary power pigtail with inline fuse, an accessory hardware bag (side screws, mic clip, bracket pads), owner's manual, and warranty card. The Stryker 3-year factory warranty is included.
Can I use existing Cobra or 4-pin mics with the SR-447HPC2?
Yes. The SR-447HPC2 uses a standard 4-pin mic jack — compatible with the same 4-pin Cobra and Uniden microphones many drivers already own. No proprietary mic connector to work around.
Is the SR-447HPC2 pro tuned and aligned when it ships from CB Radio Supply?
Not by default — Stryker ships them stock. If you want yours bench-tested, peaked, and aligned for maximum output and receive performance before it leaves our shop, add our 10 Meter Pro Tune and Alignment service ($50) to your order.
What's the warranty on the SR-447HPC2?
The Stryker SR-447HPC2 comes with a 3-year factory warranty through Stryker Radios. CB Radio Supply is an authorized dealer and can route any warranty claim.
Can I run the SR-447HPC2 as a base station?
Yes. Pair it with a regulated 13.8V power supply rated for at least 12–15 amps continuous. Any quality 15A supply will handle a single SR-447HPC2 comfortably.
Does the SR-447HPC2 have a frequency counter or callsign display?
No. Unlike the SR-655HPC+ and SR-955HPC+, the SR-447HPC2 doesn't have a frequency counter display, so custom handle/callsign programming isn't part of this chassis. The rear programming port is used for firmware updates only.
