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!

Costa Brava 6M fun!

Image
I'm currently on vacation in Spain.  I've been able to string up a 23m long random wire into a balun and am currently running FT-8 as EA3/G7GGW. I've been heard from Japan to Chile with my FT-891 running 25W with a LDG Z100 plus tuner. I've also made antennas for 6M  and 2M based on instructions here https://vk1nam.wordpress.com/6m-sota-antenna/ from VK1NAM's website so thanks to him for posting that. The antenna is attached to a 6M long carp fishing rod from Decathlon that compacts down to about 40cm when travelling and costs about 17 euros to buy. There is some activity on 6M and I have been received at a distance of more than 2000km!

Dual antenna hotspots

I've got two MMDVM hotspots with me here in the Spanish Pyrenees. One is a Jumbospot on a Pi Zero W and the other is a dual antenna hotspot on a Raspberry Pi B. When on the dual antenna hotspot I noticed that at the end of a QSO I could hear the last two seconds of my own voice when I de-keyed. I suspect, but haven't measured, that a dual antenna hotspot in duplex mode uses twice as much data to send an receive the QSO. So on holiday a simplex hotspot will use half the data during a QSO when compared to a dual antenna hotspot. I suspect the test will be to see what happens when only TG9 is running with no Internet connection. If I hear my own voice then the hotspot re-transmits the received signal rather than the stream if receives from the network the Brandmeister/Fusion server. Testing this is left as an exercise for the reader, I'm on holiday! ;-)
