As a way to help a good cause and to say thank you to the Lions for using their club house for Winter Field Day we are a having a impromptu eye glasses drive. The Lions have a recycle program for eye glasses. Here is a link to what they do with used glasses pdf

There will be a collection box at the meeting. If you forget to bring your used eye glasses to the meeting, you can bring your used eye glasses to Winter Field Day.

A member said they will donate $2 to the New Capital Fund for every pair of glasses donated during the meeting and Winter Field Day.

LinPac

LinPac is a program to connect to a packet BBS or do Keyboard to Keyboard Radio Communication.

Watch Keyboard to Keyboard Radio Coms with AX.25 and Linpac! and VA7SHG - LinPac - Packet radio on linux, beyond Winlink and APRS to get the idea.

The guides I used were Direwolf soundcard packet on Linux, with ax25 and LinPacSetting up Packet Radio on a Raspberry Pi (4 thru Zero-W) running Raspberry Pi OS Bullseye, Buster, Stretch or Jessie.

My system is a 64 bit Intel based laptop running an Ubuntu derivative connect to a G90. Installing LinPac on my laptop for use with my G90 required a few modifications from the first set of instructions. Many of the changes I used were in the second set of instructions.

My changes

1. The best way to control a G90 is to use Flrig.

2. Besides installing Flrig, hamlib needs to be installed.

3. direwolf.conf needs to be edited to be used with hamlib.

PPT 2 localhost:4532

4. Since LinPac is being used on HF the modem speed in direwolf.conf needs to be changed:

MODEM 300 1600:1800 7@30 /4

5. After installing all the packages for AX.25 the /etc/ax25axports file needs to be edited:

Replace my call sign with yours including SSID

wl2k W9RWB-3 300 255 7 HF

The first entry is just the name of the port. I used wl2k but you can name the port anything you like. The second is your call sign with SSID. The third is desired modem speed. Since I am on HF I used 300. I am not sure what the 255 is but every example had it. I am also unsure about the next number but if you are doing UHF use 2 and if you are doing HF use 7. The next is just a description of the port.

5. Making listen work properly

sudo chmod 4755 /usr/bin/listen

or

sudo chmod 4755 /usr/bin/axlisten

6. Install LinPac

How to start LinPac.

1. Start Flrig and make sure it is connected to your radio.

2. Run the following in a terminal window and let it run. This is command connects hamlib to flrig.

rigctld -m 4 -vvvv

3. Start direwolf with the following command: (Replace direwolf-ax25.conf with the name of your configuration file.)

direwolf -t 0 -p -B 300 -X 16 -d tx -c direwolf-ax25.conf

Only use the command options if you want to use FX.25 in place of AX.25

-X 16 and -d tx

4. Run the following command:

sudo kissattach /dev/ptmx wl2k

sudo kissparms -c 1 -p wl2k -t 300 -l 30 -s 20 -80 -f n
