Stryker SR-447HPC2: The Compact 55+ Watt PEP 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 small chassis. Rated by Stryker at 55+ watts PEP on AM and 45 watts on FM, with a seven-color LED faceplate, digital echo, variable talkback, and a slim body made for tight mounting spots, 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 includes a 3-year Stryker factory warranty and free standard shipping in the lower 48.

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, tight center dashes, factory radio cutouts, and narrow consoles all leave little room to work with. You can spec any of the big Stryker chassis you want, but if the radio doesn't fit, none of it matters. The 447HPC2 gives you a much smaller chassis to work with, without giving up the Stryker feature set.

• 55+ Watts PEP on AM. Manufacturer-rated at 55+ W PEP on AM and 45 W on FM, with enough output to get out 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.

Truck Fitment: Where the SR-447HPC2 Mounts

The SR-447HPC2 is one of the most compact Strykers we carry, which makes it a strong candidate when space is tight. Space varies by model year and options, so measure your mounting location before ordering, and allow room for the mic, power, and coax connections (the radio is 10" deep from controls to heatsink). Common places to check:

• Kenworth (T680, W900): Measure first. T680 overhead cubby; W900 dash slot.
• Freightliner (Cascadia): Measure first. Center dash; verify depth clearance behind trim.
• Peterbilt (389, 579): Measure first. Factory radio cutout, overhead pocket, or DIN opening.
• Volvo (VNL): Measure first. Slim chassis for tight VNL cubbies where a 497 won't clear.
• Mack (Anthem): Measure first. Standard bracket install.
• International (LT/RH): Measure first. Under-dash or DIN mount.
• Pickup / SUV / Jeep: Measure first. Center console, seat bracket, or under-dash.

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 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. Here's what we measured on a bench-tuned SR-447HPC2 with an LP-1000A digital wattmeter, 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, in line with the 55+ W PEP AM manufacturer rating
• 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. Bands A through H give you 40 channels per band across 28.000-29.700 MHz.

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: for programming with Stryker's downloadable software and a special USB cable, sold separately

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

License Note

The Stryker SR-447HPC2 is a 10 meter amateur radio, not a Part 95 CB. An FCC amateur radio license is required to transmit, with General class or higher required for its full 28.000-29.700 MHz range. Receive-only monitoring does not require a license.

Stryker SR-447HPC2 FAQ

Is the Stryker SR-447HPC2 a CB radio?

No. Despite the "Stryker 447 CB radio" nickname, the SR-447HPC2 is a 10 meter amateur radio operating on 28.000-29.700 MHz. An FCC amateur radio license is required to transmit, with General class or higher required for its full range. Receive-only monitoring does not require a license.

How much power does the Stryker SR-447HPC2 put out?

Stryker rates it at 55+ watts PEP on AM, 12 watts AM carrier, and 45 watts FM. On a bench-tuned radio we measured about 8.5 W dead key on high, 60+ W PEP on tone, and about 80 W voice peaks with a 13.8V supply and matched antenna. 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?

Measure first. The chassis is 6.25"W × 1.88"H × 8.25"D, 10" including controls to heatsink, and available space varies by truck, model year, and options. Allow extra room for the mic, power, and coax connections. If you're not sure, contact us with your truck details and measurements before ordering.

Do I need a license to operate the SR-447HPC2?

Yes, to transmit. An FCC amateur radio license is required, with General class or higher required for its full 28.000-29.700 MHz range. Receive-only monitoring does not require a license.

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, a 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.

What's the warranty on the SR-447HPC2?

The Stryker SR-447HPC2 comes with a 3-year factory warranty from the original purchase date through Stryker Radios. It's non-transferable and activated online. 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 to 15 amps continuous. Any quality 15A supply will handle a single SR-447HPC2 comfortably.

Does the SR-447HPC2 have a frequency counter?

No. Unlike the SR-655HPC+ and SR-955HPC+, the SR-447HPC2 has a channel display only, with no frequency counter. It is programmable with Stryker's downloadable software and a special USB cable, sold separately.
