7127 kHz on 4/4/2014 23:50 UTC What is it?
« on: April 04, 2014, 2352 UTC »
My DX-160 can only give me garbled voice on AM, but it sounds like discussion, but not in a ham-way as I cannot hear a carrier switching on/off, but m-a-y-b-e.  Any ideas?

7127 kHz on  4/4/'14 23:50 UTC  S5-10, depending on voice.  Why am I only getting garbled voice on this set at that signal strength?

You're probably hearing ham operators talking in lower side band (LSB), which will sound garbled in AM. I think the DX-160 has sideband capability?

Thanks for your reply.  Yes, I eventually sorted it out on another signal in switching to SSB/CW and adjusting BFO ever so slightly.

Question:  with my 160, does SSB setting include BOTH LSB and USB?  If so, then why do more modern receivers (like my ICF 7600) have separate setting for these two modes?
