Radio-less Node

Here is a very inexpensive way to get an AllStar node up and running.

Raspberry Pi 3 Model B, Manhattan USB Sound Adapter, Cheap Headset with boom microphone and a USB extension cable. I use a 3 foot extension cable, you may want to use a longer one.

Links to all parts will be at the bottom of the page.

Configuration:

Use Doug Crompton’s image. Here is the current link as of today. 10/11/2017 Boot the image up however you want with your node information. You may want to read more info on Doug’s site https://hamvoip.org before continuing. When completed, edit your two simple USB config files to be identical to these.

simpleusb.conf

[general]
[usb]
eeprom=0
rxboost=1
carrierfrom=usbinvert
ctcssfrom=no
invertptt=0
plfilter=yes
deemphasis=no
preemphasis=no
deemphasis = no
rxondelay = 0
rxaudiodelay=0
queuesize = 8
txmixa=voice
txmixb=no

simpleusb_tune_usb.conf

[usb]
devstr=1-1.3:1.0
rxmixerset=650
txmixaset=500
txmixbset=500

Plug your USB extension cable into one of the USB ports of your Ras Pi and your Manhattan Sound FOB into that. Then plug your headset into the Sound FOB.

Reboot your node.

To connect and disconnect your node use the CLI and commands such as rpt fun NodeNumber *3NodeNumber and  rpt fun NodeNumber *1NodeNumber.

Examples:

If your node number is 12345 and you want to connect to node number 67890 do the following in the CLI.

rpt fun 12345 *367890

<hit ENTER key>

To disconnect you would do the following in the CLI.

rpt fun 12345 *167890

<hit ENTER key>

You may also choose to use other tools such as Supermon or Allmon to control your node. There are many other options as well.

To transmit, press the Volume Down button.

Let me know if you have any!
