Stryker SR-497HPC 10 Meter Radio — The Loud, Full-Size Flagship

The Stryker SR-497HPC is a full-size 10 meter amateur mobile transceiver built for operators who want big, clean audio and real transmit power without stepping into SSB territory. With 100+ watts PEP on AM/FM, six IRF-520 MOSFET finals, a seven-color LED faceplate, and Stryker's Up-Armored™ receiver, the SR-497HPC has spent years as the shop favorite for truckers, base operators, and mobile installers who want a radio that sounds loud and hears well.

Each SR-497HPC 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 Truckers and Base Operators Choose the SR-497HPC

The Stryker SR-497HPC is built around four themes: loud, clean modulation, a receiver designed to handle rough RF environments, controls laid out for real-world use, and enough headroom to run without an amplifier. Here is what stands out.

• 100+ Watts PEP AM/FM. Six IRF-520 MOSFET transistors deliver 100+ watts peak envelope power on both AM and FM — well above what a stock 4-watt CB or a 40W entry-level 10 meter radio can produce. In real driving conditions after tuning, expect roughly 30 watts dead key on high, with peaks around 104 watts on the meter.
• Seven-Color LED Faceplate. Cycle through seven backlight colors using a dedicated color button on the front panel — no hidden menu required. The multi-step dimmer handles day-to-night driving without washing out.
• Up-Armored™ Receiver. Stryker's advanced receive filtering pulls weak signals through in dirty RF environments — truck stops, city noise, and skip conditions where cheaper radios struggle.
• Big-Radio Modulation. Stryker's ultra-high-fidelity modulation circuitry is what gives the SR-497HPC that "booming" sound. Combined with digital echo and variable talkback, your voice sits loud and clean on channel.
• Advanced NB/ANL. The noise blanker and automatic noise limiter combine to knock down engine noise, alternator whine, and pulsed RF interference.
• Automatic AWI. The Antenna Warning Indicator alerts you the moment SWR climbs into a range that can damage the finals — cheap insurance on a $394 radio.

Stryker Family Comparison: Which 10 Meter Fits Your Install?

CB Radio Supply carries the full Stryker 10 meter line. Here's how the SR-497HPC compares to the two radios most people cross-shop it against:

Not sure which one fits? Call us at the number on our contact page — we install these radios daily and know which chassis clears which dash.

Truck Fitment: Where the SR-497HPC Mounts

The SR-497HPC is a full-size chassis (11-5/8" including the heatsink). It's the "big radio" in the Stryker line — plan the install accordingly.

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-497HPC 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-497HPC will do on a Bird wattmeter with a good 13.8V supply and a matched antenna:

• Low dead key: ~12 watts
• High dead key: ~30 watts
• High output peaks: ~100–110 watts PEP
• Current draw at full modulation: up to ~14 amps on FM

Note that on this radio, the dead key changes more between low and high than the modulation peaks do — that's how the variable power control is designed. If you plan to drive a linear amplifier later, keep dead key low and let the amp do the work.

What's in the Box

Controls Walkthrough: Left to Right

Top-Left Concentric Knob: Talkback + RF Power

• Outer ring: Talkback / monitor volume
• Inner knob: RF power — sets both dead key and peak output

Band Switch

Bands A through H, PC programmable. Most operators leave it on the 10 meter amateur band (D) and stay there.

Volume + Squelch (Concentric)

Volume up front, squelch on the back ring. Squelch cuts background hash so you only hear traffic strong enough to break threshold.

Mic Gain + RF Gain (Concentric)

• Mic gain: transmit audio level. Turn down if you're overdriving or getting complaints about being "too loud."
• RF gain: receive sensitivity. Turn down in strong-signal environments to keep the receiver from being overwhelmed.

Echo Volume + Echo Delay (Concentric)

Independent volume and delay controls for the digital echo — Stryker labels this pair "Volume/Delay." Small twist of delay + light echo gives that classic full-bodied Stryker sound without sounding cartoonish.

Color Button

Cycles the LED faceplate through seven colors. One press to change, no menu required.

Mode + Beep + Filter Switches

• AM / FM / PA: operating mode
• Roger Beep 1 / Beep 2 / Off: two selectable end-of-transmission beeps or none
• NB+ANL / ANL / Off: noise blanker and noise limiter modes
• 10K switch: shifts operating frequency by +10 kHz for quick channel separation when two radios are running side-by-side

Rear Connections

• UHF SO-239 antenna jack. Pair with the Stryker SR-A10 Antenna for a matched Stryker install, or with a Skipshooter if you want more length. Use Stryker's magnetic mount for temporary installs.
• PA speaker output
• External speaker output
• Frequency counter jack pre-wired for FC-390-style counters
• Robust heatsink with internal automated fan
• Easily accessible external fuse holder — automotive-style fuse, no need to open the case for replacement

Recommended Accessories

The SR-497HPC's stock mic gets the job done, but customers who care about audio quality nearly always upgrade. Here are the accessories our install techs use:

• DRX-6560 4-pin noise-cancelling dynamic microphone — direct plug-in, big improvement over stock
• Astatic 636L noise-cancelling mic — classic choice, wired for Stryker/Galaxy 4-pin
• Stryker SR-A10 antenna — matched pairing, 2-year antenna warranty
• Gear Keeper RT4 retractable mic keeper — keeps the mic off the floor when you're not on channel

Want a complete install? Ask about our SR-497HPC + SR-A10 + mirror mount + 18-ft coax combo — everything you need to install this radio from bare metal.

Licensing: You Need a Ham License

The Stryker SR-497HPC 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 the study time is measured in evenings, not weeks.

Stryker SR-497HPC FAQ

How much power does the Stryker SR-497HPC put out?

The SR-497HPC is rated for 100+ watts PEP on both AM and FM using six IRF-520 MOSFET transistors. After a proper Pro Tune and Alignment, expect roughly 30 watts dead key on high and 100–110 watts on the peaks with a matched antenna and good 13.8V supply.

Does the Stryker SR-497HPC have SSB?

No. The SR-497HPC is an AM / FM / PA radio. If you need single sideband, look at the Stryker SR-955HPC+ (100W AM/FM + SSB) instead.

Does the SR-497HPC have a NOAA weather radio?

No. NOAA weather channels are not built into the SR-497HPC. If you drive through tornado country or want weather alerts inside your radio, the Stryker SR-655HPC+ adds NOAA weather to the same 100W chassis class.

What's the difference between the SR-497HPC and the SR-447HPC2?

Same brand and same Stryker sound quality, but different physical size and power tier. The SR-447HPC2 is a compact chassis (6.2" wide, 1.9" 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. If you have the room and want maximum audio and reach, choose the 497. If space is tight, choose the 447HPC2.

What antenna should I pair with the SR-497HPC?

For a matched Stryker install, use the Stryker SR-A10. For longer signal reach, look at a Skipshooter. Either way, tune the antenna to the operating frequency after install — the SR-497HPC's Automatic AWI will bark at you if SWR climbs too high, which is your cue to stop and adjust before the finals take a hit.

Do I need a license to operate the SR-497HPC?

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's included with the Stryker SR-497HPC?

Each SR-497HPC ships with the radio, a Stryker stock 4-pin microphone, a DX1-style mounting bracket with hardware, a proprietary heavy-duty Stryker power cord, an accessory bag (mic clip, side knobs, screws), and the owner's manual. The Stryker 3-year factory warranty is included.

What's the warranty on the SR-497HPC?

The Stryker SR-497HPC comes with a 3-year factory warranty through Stryker Radios. CB Radio Supply is an authorized dealer and can help you route any warranty claim.

Is the SR-497HPC 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.

How does the 10K switch work?

The 10K switch shifts the operating frequency by +10 kHz. It's used most often when two operators want to stay off each other's exact frequency during a group ride — flip 10K on and you're mid-channel instead of stepping on your partner. It's a quick channel-separation trick, not a permanent frequency change.

Can I run the SR-497HPC as a base station?

Yes. Pair it with a regulated 13.8V power supply rated for at least 20 amps continuous (the radio can pull ~14A on FM peaks). Any quality 20–25A supply will handle a single SR-497HPC comfortably.

What's the difference between the low and high power settings?

The dead key (idle carrier level) is what changes most between low and high — roughly 12W dead key on low vs. 30W dead key on high. Modulation peaks after tuning land in the 100–110W range on both settings. If you're driving a linear amp later, run low dead key and let the amp handle the swing.

Does the SR-497HPC fit in an overhead truck cubby?

Usually no. The SR-497HPC is a full-size chassis (7-7/8" wide, 2-3/8" tall, 9-1/4" deep — 11-5/8" including the rear heatsink). For overhead cubbies in Peterbilts, Kenworths, and Volvos, look at the compact Stryker SR-447HPC2 (6.25" × 1.88" × 8.25") or the short-chassis SR-655HPC+ (9.25" × 7.875" × 2.375").
