Hi All,
does this SM1000 effect any significant improvement of FreeDV's current
performance? If yes, what's the reason for?

Betreff: [Freetel-codec2] Setting up the new SM1000
Hi there,
I got my SM100 yesterday and just set it up on my FT-897D.
Please be aware that the RJ45 pinout on this YAESU is different from the
description in "SM1000 FreeDV Adaptor".
If someone wants to use the CN12 please with the FT-897D please connect:
pin 7 to pin 9 (GND),
pin 6 to pin 14 (PTT),
pin 5 to pin 15 (RIG MIC),
pin 4 to pin 11 (MIC GND) and
pin 10 (PTT GND) to pin 13 (SPKR GND).
Maybe it also works without the speaker ground and direct connection from
pin 7 to pin 13.
The RJ45 of the FT-897D doesn't have a speaker signal, so the headphone
output has to be used with a separate cable.
I could easily set the correct driving level not to produce any ALC on the
PA.
First tests show good audio on direct SSB RX and TX.
This evening will proceed with codec2 tests.
Regards
Gerhard OE3GBB
