Regarding noise reduction and the BHI products; I've noticed that the BHI ANEM works substantially better than the K3's NR. For whatever reason, whenever I switch NR on, the band noise seems to get attenuated slightly, but then reshaped to resemble noise in a tunnel. It's very tiring to listen too.
Any suggestions? 73 de James K3JPS Trevor Smithers wrote: > As far as I'm aware there are two companies that produce this technology for the amateur > market, BHI in the UK and Michels-Engineering in Germany.
