Demonstration of a Cisco SPA504G IP Phone on AREDN Mesh Using Battery Power

Parts list:

  • TP-Link CPE610 Dish with POE adapter connected to a local ARDEN MESH AP over RF
  • TP-Link TL-SG105E Managed Switch
  • Cisco SPA504G IP Phone
  • Generic 150w DC to AC converter
  • Duracell 7aH AGM 12v DC Battery

The video shows direct dialing via IP address. No PBX or external internet is needed for point to point connections as long as both nodes are connected to the same greater ARDEN mesh nework. Also, there are various ways to power up the devices. I chose the simple route of using existing AC adapters plugged into a DC to AC converter. You can …

Our First Summit Activation

My wife Julie (KN6AOC) and I did our first summits on the air activation over the weekend at Strawberry Peak W6/CT-086 in the Twin Peaks area between Lake Gregory and Lake Arrowhead.   I logged 23 contacts and Julie got 17.  I also made my first summit to summit contact with K1BAA who was working the Table Mountain W6/CT-067 summit near Wrightwood some 23 miles away.  And for a bonus, I sent a WinLink message to Cerritos American Red Cross station KK6SMD-10, about 50 miles away.  My longest contact of the day was 100 miles away with station KI6YLQ in Ridgecrest.  …

Antennas for Emergency Communications

Over the past year, I have experimented with a lot of antennas trying to find a good combination of gain and portability since the majority of my contacts are in the field. I will summarize my observations and make some recommendations broken down into two categories: packable and transportable.  There are plenty of good vehicle-mounted and home base antennas to talk about, but since this article is about emergency communications in the field (as in, on foot or on a bike – my experience), I won’t discuss those here.

Packable Antennas

By “packable”, I literally mean an antenna that can …

Yaesu System Fusion with a Pi 2 Model B

While experimenting with the digital world, I thought I’d try to build a Pi-Star as a connection point for my Yaesu FT3DR.  There are plenty of tutorials online on how to do this, so I won’t get into that.  I’ll just say that yes it works and it only took about an hour from downloading the latest Pi-Star image, formatting the SD card and configuring the Pi-Star to get up and running. 

Compared to the Wires-X software, I definitely like the Pi-Star dashboard better since it keeps track of everything I hear and it’s linked up to QRZ.com for looking …

FT3DR No Audio on Wires-X

A rather odd thing happened with my Yaesu FT3DR when connected to the computer with the SCU-39 USB audio cable – I could transmit but could not receive any audio!  I knew that the radio’s audio was working because I could hear non Wires-X stations just fine – just no digital.  I tried reinstalling the Wires-X software – no change.  Finally I realized that the radio was starting up in Analog Wires-X mode.  The only reason I noticed this was by looking at the log that shows up in the Wires-X software and then over at the radio which was …

Yaesu FT3DR Digital Fusion Untethered Using ZUM Spot USB

A few weeks ago I bought the Yaesu FT3DR and the SC-39 Wires-X interface cable kit.  Wires-X makes it possible for me to talk to other Ham operators all around the world while I’m at my home where the path to nearby repeaters is obstructed by hills all around.  By itself, this has been a blessing to be able to talk to people outside Orange County, checking in on the current state of affairs as we all weather this COVID-19 pandemic.  I’ve also experimented with taking my home setup mobile in a previous article, “Fully Mobile Digital Ham
