I have not used one, but they do have a very good reputation. It is not a great DX machine, but it is a great, well built, reliable & easy to use SWL receiver. That many SWL's have & would never think of parting with. These radios were also sold under both a Garex & a Lowe badge. This radio will never compete with a top line SWL RX. But lots of SWL's would also NEVER change their Target for anything else either.
I use one alongside my old FRG7, good solid receiver, easy to use just need to remember to offset upper/lower ssb freq +/- 2Kcs on digital read out. I think it is possible to adjust freq readout but not sure what happens on am then, you get used to it I can email you the user manual as a pdf if you want to check it out. Dave
The original radio was the AKD HF3, however, AKD sold the design to Garex who in turn sold it on to Spectrum. I had one many years ago. It was a basic HF receiver, sensitivity is not a problem on HF but the filtering could have been better. I have a CommRadio CR1A which is smaller than the HF3 with superb selectivity and a good choice of bandwidths, problem is I cannot justify keeping the CommRadio having purchased a Yaesu FT991 transceiver, and thinking about a Yaesu FT817 for mobile qrp use !
