I recently acquired a RT-665/TRC-88 on eBay. There is minimal information on the set on the Internet except that was tested in SE Asia along with the TRC-77, HC-162, among others for Special Forces use. The PRC-74 eventually won the competition. Anyone have any docs for this set? -- Joseph Pinner Kingston, TN KC5IJD / NNN0PHR Roane County OES 408
