While it could be many more things than I might mention here,
If your alinco is in simplex mode (single half duplex) you may
have the incorrect duplex mode set for it if you are seeing ping
What is it ?
Sometimes you may be picking up EMI pulses from the transition on
the COS line.
So say some more about it and perhaps we can hone in on it.

I finally received my Alinco DR-135 and hooked it up this morning,
but I am having a couple issues. I am currently testing it low
power over a simplex freq. Eventually it will be setup as an
in-band link to my 2 meter repeater. I've set the simpleusb
levels, and have made connections on Allstar and Echolink.
Everything appears working ok there, and audio is good. DTMF
commands are working fine as well.
However, I am not getting any audio on the dvswitch side of
things. I am linked to my TG (my 7 digit DMR ID), and I can hear
audio when I talk thru my hotspot and listen on the dvswitch
mobile app. I can also TX with the mobile app and hear my audio
over my hotspot. However, no audio is being transmitted to or from
my analog HT via the node. FYI, I am using the "bundled"
ASL/dvswitch install on a rpi 3b+. If someone can steer me to
directions to get the dmr<>analog issue fixed that would be
The second problem is when I tune the Alinco to my 2 meter
repeater pair, it seems they "lock up" one another. That is the
repeater keys then unkeys (super short hang time on the repeater),
then the Alinco keys, and so on. Hoping it is just a tail time or
some other setting that needs to be tweaked in the node setup.
Otherwise my thoughts of using the Alinco as an in-band Allstar,
Echolink, DMR bridge link to the repeater is all for naught. FYI,
2 meter repeater is a 40+ y/o VHF Engineering repeater. So
changing hang times and such on the build-in controller may be an
issue. Hopefully a setting in the node will fix the problem.
Thanks in advance,
