One of the best receivers made for noisy bands is the RCA designed pre WW2 USN RAK/RAL pair.
Regen design with 2 TRF stages and a rather unique audio AVC/Limiter and excellent audio selectivity for CW. I use a RAK at times to cruise MF and LF when the static is too much for the HRO-500/LF-10 and a RAL for some vintage rig CW. Havent given it any consideration for 160 so thats been added to the list...move the 70# RAL and 41# PS to somewhere I can fit it (-; Carl ----- Original Message ----- From: "Brian Mattson" <[email protected]> To: <[email protected]> Sent: Thursday, March 29, 2012 7:27 PM Subject: Topband: How to hear through static crashes? >I find that my 1927 Regenerative Receiver does quite well with QRN.
