Many thanks to SWLing Post contributor, Dan Robinson, who recently spotted a Galaxy R-530 on eBay and notes:
Some observations on this. The R-530, and military version R-1530, were considered fairly top of the line when they were made. They’re still among the rarer radios on the used market, though not the rarest. The R-1530 is not seen often. On performance, these receivers were not on the same level as National HRO-500s, 51Js, and R-390s. This was made by Hy-Gain after all, which was not top of the heap in receiving design. However, the R-530/1530s are great looking pieces. Anyone considering these should make absolutely sure that the PLL circuit functions on all bands. Poor cosmetic condition is a tipoff that the radio had a hard life.
