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,

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;

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
