Unfortunately, the receiver overloads very easily (the "attenuator" is nothing more than a 50-ohm potentiometer across the antenna), they tend to have a fairly high "noise floor", they are difficult to "work on", especially if you don't have the extender cards, etc.</span></div><div style="background-color: transparent;"><br></div><div style="background-color: transparent;"><span>Over the years, I have had two SB-301 and one SB-303 receivers, all paired with SB-401 transmitters, still have one pair consisting of SB-301 and SB-401. The weaknesses of the SB-303 were
apparent from "day one"! I had the SB-301 / SB-401 combination from late 1967 until mid 1972 when I acquired a Collins 75S-3A, 75S-3, and 32S-3. Disposed of the SB-301 and SB-401. Got another SB-401 a couple of decades later and the SB-303. Just as soon as I could find another SB-301, I got rid of the SB-303. Have not regretted that one bit! </span></div><div></div><div> </div><div>Glen, K9STH<br><br></div><div>Website: http://k9sth.com</div></div><div></div><div><br></div><div> <div style="font-family: arial, helvetica, sans-serif; font-size: 12pt;"> <div style="font-family: 'times new roman', 'new york', times, serif; font-size: 12pt;"> <div dir="ltr"> <font size="2" face="Arial"> <hr size="1"> <b><span style="font-weight:bold;">From:</span></b> Chris Kepus <ckepus@comcast.net><br> <b><span style="font-weight: bold;">To:</span></b> Heath@puck.nether.net <br> <b><span style="font-weight:
