The English company Lowe Electronics initially sold amateur radio accessories and from the early 1980s offered a shortwave receiver from a Japanese manufacturer under its brand. The SRX-30 was a triple conversion receiver based on the Wadley circuit with 30 linear 1 MHz bands covering the entire shortwave range, not only optically but probably also technically related to the Drake SSR-1, the same set was later offered in Germany as Century-21. The digital version SRX-30D with a built-in frequency counter followed shortly.
In 1987 the company realised, that a shortwave receiver built with standard components could also be sold in Europe at a favourable price / performance ratio. Lowe's first receiver HF-125 developed according to this concept and tailored to the European market was immediately a great success. The HF-125 had only 9 controls and a straightforward operation concept with good filters but no unnecessary gimmicks, and above-average reception performance. In 1990, it was improveded to become the HF-225, the HF-225E - Europe version was tailored to the reception conditions in Central Europe with an even improved filter configuration and various circuit improvements aimed at a perfect large signal stability. The optional D-225 synchronous detector and the external frequency keypad KPAD-1 were included in the Europe package. A professional version of this receiver was the HF-235 in a 19„ rack format with the possibility of PC control, integrated frequency keyboard & additionally improved large signal performance; it was built in small quantities only.
The successor, the HF-250, introduced in 1995, still had ten controls. An infra-red remote control, 255 memories and an RS-232C interface were already part of the standard equipment, in addition to the still generous filter selection. The European version HF-250E was also the high end version of this model with optimised behaviour under difficult reception conditions with strong signal levels in Central Europe.
In 1992, a little brother joined the existing Lowe receivers: The HF-150 had an even more spartan front panel with only the frequency display, the large tuning knob, the volume control and three buttons that could also be operated in combinations and sequences. Numerous accessories like an external S-meter with an active loudspeaker, a preselector and an external frequency keyboard were available as options. With all these accessories in a rack, the receiver gives a lot to adjust and play with. Special versions were the white HF-150M marine version and again the technically improved European version.
Back to the old days: With the designation SRX-100, Lowe had a simple receiver identical in construction to the AKD Target / NASA HF-3 from a Far Eastern production with its own company brand in its catalogue.
