The R-8 model came out in 1991 followed by the R-8A and R-8B models (but I don't know their production years). Production was discontinued in 2005 but that does not mean they changed the design in those 14 years. USB (Universal Serial Port) didn't exist back in 1991. The USB 1.0 spec was released back in January 1996 but it would've been a while after that before commercial devices showed up with a USB port. Does the case actually have a USB port? USB also stands for Upper Side Band which is a feature of the R-8 series (as is LSB = Lower Side Band). Do you have the radio or are you thinking of buying one and the seller mentioned USB? I found pics of the R-8A which has a 9-pin Dsub (DB-9) port for an RS-232 serial connection. RS-232 dates back to 1962 so it existed and was employed in commercial devices before and during when the Drake R-8 series showed up. From an online ad of someone selling a Drake R-8 (found at http://antiqueradios.com/forums/viewtopic.php?f=15&t=192671&view=previous), the case looks like: http://i45.tinypic.com/15hihx2.jpg http://i46.tinypic.com/bi402a.jpg http://i50.tinypic.com/vy1bvt.jpg http://i50.tinypic.com/11c5dnq.jpg http://i47.tinypic.com/2q2log3.jpg http://i47.tinypic.com/2d15cx.jpg http://i45.tinypic.com/35am2yp.jpg http://i45.tinypic.com/2mi3kw2.jpg There is no USB (Universal Serial Bus) port shown for that model. There is a RS-232C port which matches up with the era for this shortwave radio. At http://www.universal-radio.com/catalog/commrxvr/r8.html and at http://www.universal-radio.com/catalog/commrxvr/0082.html (which is for the R8B), the specs and features are listed. USB is mentioned in the sentence: Multi-mode reception (AM, FM, *USB*, LSB, RTTY and CW) is featured throughout the range of the receiver (100 kHz to 30 MHz). So USB means Upper SideBand (just like LSB means Lower SideBand), not Universal Serial Bus. I found a manual for the R-8 at: www.wb4hfn.com/DRAKE/DrakeManuals/PDFDOCS/Drake_R8_Owners_Manual.pdf USB is not even found as a string in that document. Do you actually physically possess the unit and see a USB port on it? I finally found a site via online search that mentioned Drake's web site, which is: https://www.rldrake.com/ Looks like they long ago (11 years ago) dropped shortwave radios. https://www.rldrake.com/technical-support/summary-of-drake-models/ doesn't list any of the R-8 series. I did some FAQs listed at https://www.rldrake.com/faqs/world-band-shortwave-radio-products/ where R-8A and R-8B were mentioned but those articles are of no help to you and they do not mention USB. I happened up http://rigreference.com/en/mfr/drake. Nope, a USB port is not mentioned there, just the same RS-232 port back in the R-8 model. http://www.eham.net/reviews/detail/494 doesn't mention USB, either. It had a link to http://www.rldrake.com/swl/R8B.html (Drake's own site) but that page does not exist. That product was discontinued too long ago. http://www.universal-radio.com/catalog/commrxvr/0082rear.html shows the backpanel of the R-8B. No USB port. --- Platinum Xpress/Win/WINServer v3.1 * Origin: Prison Board BBS Mesquite Tx //telnet.RDFIG.NET www. (1:124/5013) .
