Sommerkamp was known for rebadging other manufacturers’ radios. The FT-250 might be identical to a President or Uniden model.
Allows you to monitor Plate Current (IC), Relative Power Output (PO), or Automatic Level Control (ALC).
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.
Covers the 80 through 10-meter amateur bands (3.5–4, 7–7.5, 14–14.5, 21–21.5, and 28.5–29 MHz, with optional crystals available for the rest of the 10-meter band). sommerkamp ft 250
: As a vintage rig, it is often subject to component aging. Common maintenance tasks include cleaning potentiometers, replacing electrolytic capacitors, and occasionally swapping tubes like the 12BY7A driver or 6146 final amplifiers. Manuals & Documentation
Includes Voice Operated Transmit (VOX) and a 100 kHz calibrator for accurate frequency setting.
The stands as a landmark in amateur radio history, representing a golden era of hybrid design where robust vacuum tube technology met the increasing miniaturization of components. Often recognized in Europe as the "rebadged" European version of the famous Yaesu FT-101/FT-200 series lineage, the FT-250 offers a unique blend of vintage performance, compact portability, and reliable HF communication.
Set the Bandswitch to your desired band and use the Main Tuning knob to find signals. Adjust the Grid control for maximum background noise or signal strength. Transmitter Tuning (TUNE Mode): : Detailed instruction and service manuals are available
A well-maintained Sommerkamp FT-250 typically sells for . Prices vary based on condition and included accessories. The external power supplies (especially the original FP-200/250) are integral to the system and can be difficult to find, so a complete set is far more valuable.
In the 1960s and 1970s, trade restrictions and marketing challenges made it difficult for Japanese amateur radio manufacturers to break into European markets. DJ2UT, Wolfgang Sommerkamp, established a company in Lugano, Switzerland, to import, modify, and rebadge high-quality Japanese equipment for sale across Europe.
The operator tunes the Preselector control for maximum received noise or signal on the desired frequency.
The Sommerkamp FT-250 represents a masterpiece of late-60s radio engineering. Whether you are operating it on 20-meter SSB or using it to drive a 432 MHz transverter, the radio delivers a nostalgic, high-quality audio experience. It remains a testament to the longevity of Yaesu-built equipment and is a must-have for any serious collector of vintage Sommerkamp gear. Key Takeaways Yaesu Musen (for Sommerkamp). Era: ~1969. Modes: SSB (USB/LSB), CW, AM. Decades of dust oxidize the band switch and mode pots
During the late 1960s, completely solid-state high-power transmitters were not yet commercially viable or reliable. Transistors easily burned out if the antenna system had a poor Standing Wave Ratio (SWR).
Voice-Operated Transmission (VOX) was included for hands-free operation.
Beyond its technical specifications and performance capabilities, the Sommerkamp FT 250 offers significant practical value to its users. Its durability and reliability mean that it requires less maintenance and can withstand the rigors of frequent use. This aspect, combined with its accuracy and versatility, makes the FT 250 a cost-effective option over the long term, as it can serve multiple roles from hunting to target shooting.
Provides ±5 kc variation for fine receiver tuning without changing your transmit frequency.
Because these radios are now several decades old, finding an FT-250 in pristine, plug-and-play condition is rare. If you are looking to acquire or restore one, keep the following factors in mind:
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.
