T4: Setting up digipeater function

#1
After finally discovering that my Yaesu FTM-400XDR radio does not support digipeat, I'm hoping that I can make the T4 in the same truck do the work. I have a serial interface to the T4 so I'm working at the command line.
Build 161

So far, I've not been able to demonstrate that my T4 is actually digipeating. Here's what I've done:

set enable_digi=true
set digi7_enabled=true (the number 0 and 1 give a parameter error; haven't tried 3-6 yet)
set digi7_alias=RELAY7 (so others won't likely accidentally use it)
save
reset system

when it comes back up, i see:

show enable_digi
enable_digi=true
show digi7_enabled
digi7_enabled=true
show digi7_alias
digi7_alias=RELAY7

However, when I attempt to use it as a digi, it doesn't seem to digipeat when my handheld radio is set to RELAY, WIDE2-2.

Any ideas? Cheers and 73 - Jon N7UV
