RasPi4 Setup Guide

June 11, 2022

After ramping up 2 packet nodes on the latest Raspberry Pi OS 2022-04-06 release and struggling, I decided I’d write up the steps I followed, for my own benefit, and that of others: pi4-setup.

Chromebook for Amateur Radio?

April 15, 2022

Sure! Why not? After hearing about a fellow ham’s recent experience installing GalliumOS Linux on a chromebook, I decided to take the plunge myself since I need multiple low-cost, low-power nodes for packet radio and APRS use and the Raspberry Pi is currently in low supply and expensive. Plus the built in screen, keyboard, mouse and battery is hard to beat for monitoring, troubleshooting and tweaking settings at the repeater site.

Packet Radio

March 26, 2022

Thanks to a local ham, Ed K7WCT, 3 club members have received new Signalink devices and training from myself on how to configure and use them. Unsurprisingly this has created a buzz of APRS activity and conversations about packet radio on the local repeater.

Cowlitz Ham Activity Calendar

January 3, 2022

Our recent silent key, Randy Greeley (NU7D), provided a weekly newsletter / calendar with activities of interest to ham radio operators in Cowlitz County, including nets, club meetings, and club-sponsored events. In his absence, I have compiled the most recent list of recurring events to my knowledge and will publish a calendar and ICS file containing these events for 2022 and beyond.

Local Digipeaters

September 21, 2021

In the last month, I’ve helped stand up 2 new digipeaters. One at the top of Columbia Heights in Longview and (soon to be) on Rainier hill across the river. Both of these machines have good elevation and line of sight, so in a default digipeater configuration of ^WIDE[12]-[12]$, they end up bringing in a fair bit of “out of area” traffic to the local RF channel that can clog up the works.

September 2021 Station Update

September 7, 2021

Unlike summer 2020, I found significantly less time for radio projects this year. Between mentoring a team of interns at my day job and twice as many weddings as usual, I rarely had time for more than Monday net control and occasional check ins.

Banned From Repeaterbook

February 7, 2021

Your account at Repeaterbook.com has been temporarily suspended due to unusual export activity. We are seeing multiple CSV exports occurring from multiple IP addresses less than a second apart. This could only be accomplished by some sort of bot. This puts a substantial strain on the server resources.

ham2mon scanner down for a few weeks

December 30, 2020

I’ve been having a lot of fun with the SDR scanner and ham2mon-gui interface for playing back the recorded calls. However, in the last week, there have problems keeping the calls flowing, causing the interface to be hours or days behind.

Staticman Comments

September 29, 2020

Comments make an otherwise static site interactive and engaging for readers, but for jekyll/github pages sites, there aren’t a lot of options for enabling comments. Disqus and Facebook comments are free, but include invasive tracking that slows the site down and forced sign up which increases friction and reduces contribution.

In this post, I share my 2m/70cm frequency and repeater list which I’m constantly revising and editing. I program these frequencies into my various radios to achieve somewhat consistent results regardless of which unit I’m operating.

ham2mon multi-channel scanner on macOS

September 11, 2020

This setup allows for the automatic simultaneous capture of multiple narrowband FM signals. The ham2mon-gui enables easy archiving and playback of captured files. Primarily I’m using it to listen to every 2 meter repeater within hearing distance to my home QTH of Longview, WA.
