[Drake] Going price of R4-C

Fri, 19 Mar 2004 15:18:20 -0600

Hi Bob,

Most all upgrades improve and enhance the radio's receive
quality.  Mine I have
the original SSB filter then I can select a Sherwood USB or
LSB filter.  On CW
I can use the rear filters or  engage the great 600 Hz
roofing filter for great CW
reception.
I couldn't ask for more.

Best 73,

Bill  KB9IV
