WIFI connections for Pi-Star on the raspberry pi

My hotspot is setup to connect to three WiFi networks 1) my home network, 2) tethered to my mobile phone and 3) my hotspot. The Pi-Star wifi settings (and for most Linux distrubtions are stored in a file located in /etc/wpa_supplicant/wpa_supplicant.conf. Mine looks like this: #cat /etc/wpa_supplicant/wpa_supplicant.conf ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 ap_scan=1 fast_reauth=1 country=UK network={     ssid="wifihome"     psk="mypassword"     id_str="0"     priority=100 } network={     ssid="mobilephone"     psk="mypassword"     id_str="1"     priority=99 } network={         ssid="holidayhotspot"         psk="mypassword"         id_str="2"         priority=98 } Note that each entry has a unique id_str value. Additionally I have set a preference order for connecting using the priority field. The higher the value the higher the preference. If you want

APN settings when abroad

I spent a good morning trying to get my hotspot working this morning. I'd verified if before leaving for Spain but once here I could make a receive calls and text messages but not data. It turned out the APN settings were incorrect. Once I'd found what they needed to be I changed them on the hotspot and once again, the world was my oyster!

Turning your hotspot off from your radio

The pistar OS has a nice feature to turn off or reboot the hotspot from the radio. Simply configure it with your dmr Id and connect with the following TG room numbers.

Why a Hotspot display is a good idea!

So I'm on the campsite and I've discovered why a display on your hotspot is useful. I turned on tethering on my phone but couldn't discover what IP address my hotspot had been given. I have a laptop with me but using nmap returns incorrect results. It claims there is a host active on each 192.168.43/24 ip address with port 80 open. So what to do? Using 'arp -a' I managed to discover the active MAC to IP addresses. rob@ThinkPad-X230:~$ arp -a ? (192.168.8.100) at 74:da:38:88:5a:09 [ether] on wlp3s0 www.huaweimobilewifi.com (192.168.8.1) at f0:0f:ec:95:e2:90 [ether] on wlp3s0 I was subsequently able to browse to my hotspot and all was well. The world is once again my oyster!

Lightening the load

Going on holiday this year I've decided to lighten the load. No HF gear for me! I'm taking a shortwave radio, a TYT MD380, Yaesu FT-71D and a Hotspot. I'll be tethering through my phone.

FT-817ND woes

I took a flight with my Yaesu FT-817ND the other week with my radio in my hand baggage. Unfortunately, I forgot to disconnect the battery and when I arrived at my destination I found the radio had switched on and was trasmitting without an aerial attached :-(. After one QSO the final stage broke and I can see there is modulation but there is no power output. This means a change of plans for my summer holidays!
