Didnt see any audio specs but it hints it has discriminator and

Being a DSP
based radio,
the BF888 is a
cheap low
power analog
only RF
package. Given
the lack of
discriminator
and modulator
access it is
limited.<br>
<br>
For a receiver
the Maxtrac /
Radius / GM300
work well. For
a transmitter
not so much.
Heat output
and with the
Maxtrac,
problems with
power and
deviation
control out of
band can cause
problems
without custom
firmware or
hardware
hacks.<br>
<br>
My absolute
favorite RF
gear for
Analog /
Digital
repeaters is
Tait. The T800
series is a
purpose built
programmable
Exciter /
Receiver
package. With
access to all
the signals
anyone would
want. I
started using
them for 927
MHz repeaters
and have had
great
performance on
UHF and VHF.
Mix and match
at will. Pair
a VHF receiver
with a UHF or
900 MHz
transmitter
for a nice RF
linked
receiver site.
For link
radios simplex
nodes and "Hot
Spots" I've
come to favor
the Tait T2000
mobiles. They
are easy to
program, well
documented,
lots of IO and
run cool in
transmit.<br>
<br>
The above is
not to say
there are not
a LOT of great
repeater /
node packages
out there. The
GE MASTR II
comes to mind.
I have to
mention the
Micor to keep
the flack
down. ;) I've
built
repeaters
using
everything
from a
Motorola 30D
to current
equipment.<br>
<br>
Your mileage
may vary.<br>
