[VHFcontesting] usb to 232 noise

[Dan Evans]

Has anyone had any success curing noise from a USB to RS232 adapter?

I use a "cheapy" adapter to run my sound card interface from my laptop 
when I am Roving.  Unfortunately, I've found a ton of noise on 2m due to 
the adapter.  6m has some noise, but it is not as bad.

The sound card interface is used mostly for voice and cw keying, but I 
don't want to rule out WSJT modes in the future.   However, with the 
current noise it just won't work....  Clamp on ferrite's didn't seem to 
help.   I regret selling my old Thinkpad now.   Looks like I may have to 
"down grade" my computer system, hi hi.
