I bought Lenny&#39;s PT-3 preamp years ago but recently connected it  for the first time.   I thought even though it wouldn’t be at the antenna feedpoint, it might be helpful with low band receive antennas with low output.  <div dir="auto"><br></div><div dir="auto">I tried it and it has gain, but it doesn’t really seem to help the S/N ratio.  I haven’t found a lot of online info yet, but it seems that it is mainly helpful on higher bands.  It probably would have helpful on one of my old tube rigs that lost sensitivity on 10M.  </div><div dir="auto"><br></div><div dir="auto">I just wondered if anyone else had any experience or tips for this piece of equipment, especially for use on 160 or 80 meters.</div><div dir="auto"><br></div><div dir="auto">73,</div><div dir="auto">Dennis/RZ</div>
