SB-301 Mods/Updates

[Ed Swynar]

There are a number of mods/changes to this otherwise EXCELLENT rig, as are
documented in the ARRL's "HINTS & KINKS" over the past 35 years, or so...

Most of these are probably better directed toward the SB-300 model---the
'301 is, in my opinion, probably THE best bargain in tube-type receiving
hardware to-day, even "...as is", totally stock.

I built a HB 160-meter receiving converter for mine, AND have the 6- and
2-meter Heath converters (selected coverage from 1.8-MHz to 146-MHz+!). I
also built my own broadband AM filter for mine (used an SSB type as the
foundation), and installed a really tight 250-Hz Fox-Tango CW filter in it.

It's a GREAT rig for the price, bar none...!
