Thank you to everyone for their answers to my question about using the Synchronous Detection feature of my Drake R8. I received so many replies to my inquiry, I am sending this message to the list, so as not to leave anyone out.
As suggested, I tried using it when tuning in somewhat stronger signals from other stations on other bands, and it did improve the signal strenght and intelligibility, so it is definitely not broken. As several of you commented in your replies, the two intermediate-width filters are insufficient for what is needed. The 4.0 khz filter is too wide to be truly effective on adjacent channel QRM on bradcast band, and the 2.3 khz filter is too narrow for listenable audio. I will begin working with trying to tune these signals with sideband and/or my digital signal processor and hope for better results. 73, J.D.
