I have used the older boards as well as the new
version 1.2 board. HUGE improvement!
I just moved and integrated my old board without
the de-emphasis network into another radio and put the 1.2 in the DR-135.
The upgrade is worth it.

I have a T2-135 board that is probably several
years old now installed in a DR-135 Mk II that
was new at just about the same time. I know
there's been past discussion about the decode
performance of these units and I'd just like to
get updated on the status of any fixes. I think
there was talk of some hardware changes to
better shape the audio, but I don't know where that stands now.
I do have the latest firmware build installed
(55076) and today I was running my DR-135 system
next to my other home system using a Yaesu
FT-1500M and AGWPE and the home system is
decoding many more transmissions than the
Alinco. I'm using two identical antennas at the
same height with just about the same
transmission line lengths and quality. The
Alinco gets most of the strong signals, but the
weaker ones are not handled well. The radio
hears them (the "meter" moves) but the board does not decode them.
So, is there a practical fix for those of us who
are a little hesitant about surface mount techniques?
