I want to buy a Kenwood R-300 or QR-666, help!

I would love to purchase a Kenwood R-300 or QR-666 (don't make fun, I like playing with these old guys) If someone has one sitting under a pile of old radio parts, that they wouldn't mind parting with...I'd luv to hear from you and we could work out a price. =) If you have one let me know. *drop me and e-mail or whatever* Not much info in the 1976 WRTH, but here is the pertinant stuff: Selectivity: 2.5 and 5 kHz. Sensitivity: AM 2 uV CW/SSB 1 uV Says that the shape factor of the filters is not good. There are images and birdies. There is an optional calibrator available, QR-6 MK, 500 kHz.

Enjoyed your two analog auldies reviews, Judah(have both around da shack,
also). Found some info on your two "new" requested Trio-Kenwood receivers in Fred J. Osterman's first edition "Shortwave Receivers Past and Present". The R-300 was manufactured in 1976, and has 170-30,000 khz coverage. Has band spread, just like your Realistic DX-160. Six bands: Band A is 170 - 410 khz; Band B, 525 - 1,250 khz; Band C, 1.25 - 3.0 mhz; Band D, 3 - 7.5 mhz; Band E, 7.5 - 18.0 mhz; Band F, 18.0 - 30 mhz. Sensitivity for band A is better than 1 microvolt in a.m. mode, 0.3 uv in s.s.b./c.w.; 0.3 uv a.m. & 0.3 uv s.s.b./c.w. for Band's B ,C, & F; 1.5 uv a.m. & 0.5 uv s.s.b./c.w. for Band's D & E. Selectivity in narrow mode: more than 2.5 khz @ -6 db, less than 12 khz @ -60 db; in wide mode more than 5 khz @ -6 db, less than 17 khz @ -60 db. Audio rated @ 1.5 watts @ 8 ohms with 10 % distortion. Uses 8 watts-per-hour a.c. ... Here are 1975-vintage QR-666 specs: Same six band ranges. Sensitivity: 3.0 uv in a.m. mode, 2.0 uv s.s.b./c.w. for Band A ; 1.6 uv in a.m. and 1.0 uv s.s.b./c.w. for Band's B & C; 2.0 uv in a.m. & 1.4 uv s.s.b./c.w. for Band D; 3.0 uv in a.m. & 2.0 uv s.s.b./c.w. for Band's E & F.
