Good afternoon all,
I run the MB7IIP node in the UK and at present have an
Alinco in 9600 Baud running my node. The USB mod on the key fob works great and
I would like to add a 70cm link. The radio is a Yaesu VX 2000 can someone give
us a hand with the connectivity of this radio and the changes to my USB config
please.
I have included the wire code I have and the wire code of
the VX2000. I have swapped the TX RX over as this seemed to me as the only
change needed but still nothing from DTMF. I can go into asterisk and force a
ptt as a console command and the radio will then PTT help now needed as I have
tried most of last night and today. Many thanks for any help
Details are:
The Alinco is wired as follows and I have flat audio
set on key fob plus key fob is sorting CTCSS
:
The Yaesu VX2000 is as follows as this too has a 9 pin
connector on the rear of the radio. The radio is set in DFLT mode at the
moment.

Squelch
Output
High
level (5VDC / 47 kOhms) when carrier received. This does NOT care
about any kind of coded squelch, just RF signal.

Receive
Audio
Output
DFLT - De-emphasized Audio Output:
100mV, 10 kOhm. The output level is fixed at the factory by having no jumper
at JP1003 and soldering the jumper at JP1002 on the Main unit.
ALT - Flat (not De-Emphasized) Unmuted Audio Output: 250mV, 10 kOhm.
Unsolder the jumper at JP1002 and solder a jumper at JP1003 on the Main unit.

DFLT - Pre-Emphasized / IDC /
Splatter Filtered Audio Input: 2.5mV, 600 Ohm. This input is fixed at the
factory by attaching capacitor C1254 across JP1005 and soldering a jumper at
JP1004 on the Main unit.
ALT - Flat (not Pre-Emphasized) Audio Input: 650mV, 10 kOhm. Remove
the jumper at JP1004 and solder a jumper across JP1005 on the Main unit.

jumper at JP1001 on the MAIN Unit.

I
hope someone can assist in the wire code changes from the Alinco to the VX2000.
If whomever can help explains that the VX2000 would work better if I change to
the ALT method I am happy to make the changes.
Once
again many thanks
