[Boatanchors] Boatanchor receiver

Wed, 11 Feb 2004 18:17:40 -0800

I think most of the ham and SWL world doesn't understand receivers and 
what takes to receive radio signals below 30 mHz. The Drake R4b (not the 
R2, r3 or r4a or c) is by far the better receiver as far as performance 
is concerned. It is not designed to be general coverage and to get it to 
go places where it is not equipped requires changing some crystals. The 
intermod, IF distortion and detector circuitry is far in advance of any 
other of the tube receivers and has only recently been equalled by some 
high end SWL solid-state receivers and multi-kilobuck ham equipments. It 
is not the easiest receiver to operate, but it is worth the learning curve.

Get a copy of Rohde's, etal, book on receiver design from the ARRL 
bookstore. He understands receivers a bunch.

Drakes were rated good but don't "look the part" & "AM filter is too tight".
