Fred, this list is NOT a place for personally insulting remarks such as that. That type of behavior is not tolerated here.
Besides, as far as I am aware, Cory has, and uses, more then his 'ears' to make such determinations. He is one of the people on this list that has good, proper test equipment, and knows how to use it.

Cory, You might have your hearing checked, you most likely think
d-star sounds good also.
I never said USBradio was horrible, simply said usbradio audio is
superior. It's a subjective thing, most can hear the difference..
obviously you can't or you would not have made such a statement...
The only answer to the argument you want.. Fred

What degraded audio? I have ran many many test and have yet
to find this 'degraded audio'. I have heard people talk about
it but have yet seen any proof...

Larry can't answer #1.
I simply program the radio to provide what I want on the
accessory connector, then there is no EEPROM needed.
As for answer #2
When you have COS and CTCSS (PL) available use simpleUSB it
not only requires less processing power, it also does not
suffer from degraded audio.
Just add the file and stanza you need..

Two questions for the group:
#1 I'm seeing this in my /var/log/asterisk - I'm using a
DMK URI with EEPROM and a Motorola GM300 with one of
Marshall's Motorola Maxtrac, GM300 and M120 16 Pin Radio
to URI cables.
[Nov 1 11:30:05] NOTICE[6852]
chan_usbradio.c: USB Adapter has no EEPROM installed
or Checksum BAD on channel usb42372
I understand that the benefit of the DMK URI with
EEPROM is that the interface configuration can be
stored in the URI as apposed to (where else?) - is
this URI EEPROM feature taken advantage of with
app_rpt and associated drivers?
#2 How do I choose which channel driver to use -
simpleusb or USBRadio? From what I've been able to
learn through varius wikis and posts on the subject, I
would want to use simpleusb because all of the
hardware connections for COS and CTCSS are provided so
there is no reason to use the DSP features of USBRadio
thus simplifying what the driver has to do and perhaps
lowering the CPU utilization. I've also read some
posts that describe audio degredation in the USBRadio
driver but I can't tell you the cause. I expect the
right answer here is for me to try out both and
experiment - which I will do but would appreciate any
wisdome from the group on their experience with these
drivers when using the DMK URI and hardware
connections for COS/CTCSS. My current configuration
below is getting favorable audio reports.
I have no simpleusb.conf in my /etc/asterisk
I have usbradio.conf and
usbradio_tune_usb42372.conf
I have the following in my
rpt.conf: rxchannel=Radio/usb42372
I have the following in my usbradio.conf:
