[Premium-Rx] Tuning Knob's-past and present...

[Clemens Ostergaard]

The new fabulous edition of Fred Osterman's "Shortwave Receivers Past and
Present. Communications receivers 1942-2013" Fourth Edition, that came out
in August this year, now includes even more of the great receivers that we
are referring to here. Now from 370 manufacturers the world over, compared
to the 100+ represented in the Third Edition of the work. Mouth-watering
reading indeed.  And Boris, the P-250 is on page 744 :-)   While Ten-Tec's
RX-340 graces the back of the book's cover. How lucky we are to have this
kind of reference work, and in an updated, yet not pricey, version.

Best,

Clemens
