Sommerkamp Ft 250 Upd Jun 2026

The Sommerkamp FT-250 is a charming time capsule. It was a reliable workhorse in its day, but today it is functionally obsolete for most amateur radio operators. Unless you love the smell of old electronics and the challenge of restoration, put your money toward a modern handheld (even a cheap one will outperform it for everyday use).

The "FT" designation in the model name is a clear nod to the Yaesu lineage (think of the legendary FT-101 or the FT-290). While the FT-250 was targeted at the CB market rather than the Amateur (Ham) market, it carried the same philosophy of "form follows function." It was built to be a reliable communication tool, not a toy.

This is the most notorious problem. The PLL board uses obsolete capacitors and a reference crystal that can age. Symptoms: The LED display flickers, the radio won’t transmit, or the frequency jumps. sommerkamp ft 250

Affectionately nicknamed by hams because the tubes generate significant heat during operation. 🛠️ Maintenance & Common Issues

The FT-250 is primarily a vacuum tube-based radio with 16 tubes, though it utilizes 7 transistors and 15 diodes for specific low-level functions like the VFO. The Sommerkamp FT-250 is a charming time capsule

80, 40, 20, 15, and 10-meter amateur bands. Modes: SSB (USB/LSB), CW, and AM. Power Input: Approximately 240W PEP (SSB) and 100W (CW).

Thus, the is physically and electronically identical to the Yaesu FT-225. If you open the case, you will find Yaesu-branded circuit boards and components. This “twin” relationship is crucial for owners today, as service manuals and spare parts for the Yaesu FT-225 are 100% compatible with the Sommerkamp version.

This is where the FT 250 truly shines and why collectors seek it out. The receiver on SSB is surprisingly quiet and selective. The built-in 10.7 MHz crystal filter (typically 2.4 kHz bandwidth) provides adequate adjacent-channel rejection for contesting or DXing. A 10-watt SSB signal on 2 meters, when combined with a small yagi antenna, can work tropospheric ducting (tropo) distances of hundreds of miles. For a mobile rig of its era, the SSB performance is exceptional.

One quirk: Changing mode on the FT 250 requires adjusting the RF gain and volume settings. The receiver’s sensitivity on SSB is different from FM, so expect to re-tweak the controls.

To understand the FT-250, one must first understand the company behind the name. Sommerkamp is a name that carries significant weight, particularly in Europe. Founded in Germany, the company became synonymous with high-quality amateur and CB radio equipment in the 1970s and 1980s.
