The Sommerkamp FT-250 stands as a legendary icon in the world of vintage amateur radio. Released in the late 1960s and stretching into the 1970s, this High Frequency (HF) transceiver is a textbook example of Japanese engineering prowess rebranded for the European market.
A direct sibling to the famous Yaesu FT-200 and the North American Tempo One (marketed by Henry Radio), the FT-250 served as a reliable gateway for thousands of hams to experience the thrill of global shortwave communication. It remains a highly sought-after collectible and restoration project for "boatanchor" and hollow-state radio enthusiasts today. Historical Context: The Sommerkamp Brand
To understand the Sommerkamp FT-250, one must understand the branding of that era. In the 1960s and 70s, a Swiss entrepreneur named DJ2YR, Wolfgang Sommerkamp, recognized the incredible quality and affordability of nascent Japanese amateur radio equipment coming from Yaesu Musen.
Because of import restrictions, shipping logistics, and marketing strategies in Europe, Sommerkamp imported these radios, slapped on his distinct Sommerkamp badge (often featuring a vibrant blue or distinct grey cabinet), and sold them across the continent. Thus, under the hood, the Sommerkamp FT-250 is functionally identical to the Yaesu FT-200, featuring the exact same legendary hybrid design and circuitry. Core Specifications and Capabilities
The FT-250 was built specifically for the traditional, pre-WARC amateur bands. It covers the 80, 40, 20, 15, and 10-meter bands. Because 10 meters is a massive segment of spectrum, the band switch isolates it into four distinct 500 kHz segments.
Modes: Single Sideband (Selectable USB and LSB), CW (Morse Code), and AM (Amplitude Modulation).
Power Output: Rated at an impressive 240 watts DC input for SSB (roughly translating to around 100 to 120 watts of actual RF output power to the antenna).
Architecture: A "hybrid" design. It utilizes 16 vacuum tubes, 15 diodes, and 7 transistors. This was the transitional sweet spot between pure, glowing glass and modern solid-state technology.
Filter: A high-quality 9 MHz crystal filter providing excellent sideband suppression and a warm, distinct receiver audio.
Weight and Size: The transceiver unit itself weighs roughly 17.5 pounds (8 kg), with a matching heavy iron power supply unit weighing even more. Anatomy of the FT-250: Hybrid Design
The Sommerkamp FT-250 is loved because it offers the best of both worlds: the reliability and low noise of solid-state oscillators with the brutal durability of a tube-driven power amplifier. The Receiver Section
The receiver is largely solid-state and pre-mixed vacuum tube architecture, featuring high sensitivity (0.5 uV for a 10 dB signal-to-noise ratio). It boasts a ±5 kHz receiver offset ("Clarifier" or RIT) that allows a operator to fine-tune a frequency without moving the transmit frequency. The Transmitter Section
The transmitter is where the tubes truly shine. To generate massive RF power, the FT-250 uses a 12BY7 driver tube pushing a pair of robust 6JS6C sweep tubes in the final power amplifier cage. These final tubes are incredibly tough but require proper "dipping and loading" (manual tuning of the plate and load controls) to output a clean signal without overheating. Essential Accessories
Operating an FT-250 requires outboard hardware, as it was not an "all-in-one" desktop box.
FP-250 / FP-200 AC Power Supply: The radio does not have an internal power supply. It requires a large external brick that provides the high voltages (up to 600V or more for the tubes) and features a built-in front-facing speaker.
DC-250 / DC-200 DC Supply: For mobile or field use, Sommerkamp offered a heavy-duty 12V DC inverter power supply to run off a car battery.
FV-200 External VFO: While the radio has a great internal analog dial, an external variable frequency oscillator allowed split-frequency operation, highly useful for chasing rare DX stations. Operating a Restored FT-250 Today
If you manage to find a Sommerkamp FT-250 in the wild, you are looking at a masterclass in analog operating. There are no menus, no screens, and no automated tuning.
Warm-up Period: Because of the vacuum tube oscillators, the radio needs about 15 to 30 minutes to thermally stabilize. Without this, the frequency will slowly drift.
The Manual Tune-up: To transmit, the operator must switch the unit to "Tune," observe the current meter, and quickly peak the "Grid" control while dipping the "Plate" control. Leaving it keyed in tune mode for more than a few seconds can permanently ruin the final tubes. If it’s an amateur handheld: Might be a
The Joy of Analog: Spinning the massive, weighted analog VFO dial provides a sensory experience digital radios simply cannot replicate. Common Maintenance Issues
Due to the age of these units, anyone looking to buy an FT-250 should be prepared to do some basic electronic servicing:
Capacitor Failure: The electrolytic capacitors in the external FP-250 power supply are likely dried out and must be replaced to avoid a catastrophic short circuit or loud AC hum.
The "Finals": The 6JS6C sweep tubes can be expensive and hard to find. Many operators modify the radio to use more common 6146B tubes, though this requires circuit modifications.
Dirty Switches: Decades of dust oxidize the band switch and mode pots. A thorough cleaning with a dedicated electronic contact cleaner (like DeoxIT) is usually the first order of business.
Ultimately, the Sommerkamp FT-250 is a gorgeous monument to the golden age of amateur radio. Whether it is resting on a shelf as a display piece or glowing in a dark room making contacts on 40-meter CW, it remains a beloved artifact of 20th-century communications history.

The Sommerkamp FT-250 was a distinctive CB radio from the late 70s, known for its rugged build, 40-channel AM operation, and a unique “side-mic” design. Here’s a story built around that specific model.
The summer of ’79 was the hottest in a decade, but inside the cab of a rust-spotted Ford F-250, it was even hotter. Not from the sun—but from the low, angry static of a Sommerkamp FT-250.
To 17-year-old Leo, the radio wasn’t just a CB. It was a lifeline. His father had bolted that Sommerkamp under the dash before he left for the oil fields of Oklahoma, saying, “Kid, that black box has ears like a rabbit and a voice like a preacher. You listen more than you talk, you’ll be fine.”
Leo wasn’t fine. He was hauling a trailer of stolen tractor batteries, his knuckles white on the wheel. Behind him, two miles back, a sheriff’s cruiser had its lights off but its engine hot.
He keyed the Sommerkamp’s side-mounted mic—a weird design most truckers mocked, but Leo loved because he could palm it like a grenade.
“Breaker, breaker. This is… Rust Bucket. Any Smokey reports on the 101 south, mile marker 42? Over.”
Static. Then a voice like gravel and coffee: “Rust Bucket, you got a tail. Bear in a plain white wrapper, two ticks behind. You copy?”
Leo’s heart slammed. “Copy that, good buddy. Solid copy.”
“Sommerkamp sounds clean, son. You running a silver-stick antenna?”
“Yeah. 1.2 SWR. She’s tuned.”
“Good. Now listen: there’s a dirt turnout exactly 0.3 miles ahead. Kick up dust, kill your lights, and let the bear roll past. He’s looking for a Ford with a mismatched tailgate—you got one, don’t you?”
Leo glanced in the side mirror. The tailgate from a ’72 Chevy was held on with bungee cords. “Maybe.”
“Figured. Now move.”
Leo cut the wheel, bounced onto the dirt path, and killed the headlights. Dust bloomed like a ghost. Thirty seconds later, the white cruiser hummed past, its radar gun sleeping.
He grabbed the mic. “Who is this? You saved my hide.”
A long pause. Then: “Name’s Lonnie. Used to run a Sommerkamp FT-250 back in ‘77 till a fuel pump fire took my rig. Still got the radio, though. Got it bolted to my porch railing. Power it with a deep-cycle battery. Pulls in signals from three counties away.”
Leo laughed—a real one, the first in weeks. “You hear anything else out here tonight?”
“Just you, kid. And the sound of a future you shouldn’t throw away. Those batteries belong to Miller’s Farm Supply. The man has three kids and a bad back. Drive back there before sunrise. Leave them at the gate.”
The mic went silent. Leo sat for a long minute. Then he put the Ford in reverse, turned around, and headed north—not away from, but toward the trouble he’d caused.
He never heard Lonnie again. But every crackle of the Sommerkamp FT-250 after that night sounded less like static and more like a second chance.
As with any radio approaching 40+ years of age, specific maintenance issues are common:
The defining feature of the FT-250 was its power. Delivering roughly 25+ watts of output power, it provided a significant range advantage over standard legal CBs. This made it a favorite for "shooting skip" (communicating over long distances via ionospheric propagation).
