A Plethora of Projects Q2 2025 Edition

It’s hard to believe it’s been 3 months since I last posted – which roughly coincides with my return to work post-Christmas. It should therefore come as no surprise that I am on leave from work and am now trying to catch up.

I’ve had many projects happening, but the problem with having many projects is that you get less time to focus on each one. Here’s what been going on:

Radio Club Website

My local radio club, REAST, has a website that I maintain. With the need to migrate web hosting providers it was time to, as part of the process to give the site some TLC, with much of it’s platform code having been neglected for 5 years or more. Fixing the site theme, replacing plugins that were no longer developed and adding functionality for editors have been just some of the things being worked on.

Packet Radio

I definitely have not forgotten about my packet radio project, though it has taken a back seat in recent times. I now can re-welcome an MFJ-1720B back into the fray with the help of another hobbyist and might post on that again shortly. I still need to do some more work on trying to understand how to connect my node to the greater 44Net.

Portable Operations

As I have discovered, summer has not been particularly good to attempt portable radio operations in the general Hobart area, with strong sea breezes making the nearby POTA locations impossible to operate from. While we are now seeing more moderate conditions, we’re also seeing a loss of daylight much earlier again now, with daylight savings ending next week which will make it dark by 6pm, and then in a couple of months it will be dark by 4.45pm. Realistically POTA on weekdays probably will not start up again until September/October.

Outdoor Upgrades

Outside, it’s time to replace coax. Most of my coax was originally gifted to me when I started in the Hobby – 20 years ago, which an expectation it is at least that old again. There are signs of water ingress, so it’s time to replace.

I recently bought some aluminium poles to assemble a second fence-mounted mast at home, with the plan that the packet radio node can get a dedicated antenna.

Also mulling the idea of retiring my Bushcomm antenna from service, which while it has performed admirably, I feel like a 80m EFHW may now be a better option for my changing antenna setup and coax placement.

Indoor Upgrades

Frustratingly Microsoft in their infinite wisdom have decided that Windows 11 cannot run on the CPU of my existing ham radio computer, despite being more than adequate for its needs. Along with the stagnation of development of Ham Radio Deluxe, this has left me agonising over what the upgrade/replacement path, given the choice of running Win10 without security patches, purchasing a second-hand Win11 capable laptop, or switching to Linux and using alternate ham radio applications.

Anyway, I am sure there will be more posts in the coming weeks as I make my way through my backlog!

Just what is NET/ROM?

Introduction

One of the things that was important to get working this time around with my Linux TNC Node interface was the concept of a “NET/ROM”. Perhaps naively in a post-internet world, my mind jumped to this being a gateway between nodes available via radio and via the internet, meaning I could connect to any BBS around the world that is using “netrom”. The reality is a lot more complex.

According to the Linux Programmers Manual (man netrom)

“NET/ROM  is  a  protocol used extensively by radio amateurs. The Linux NET/ROM protocol family permits access to these protocols via the standard networking socket metaphor.”

It would appear that NET/ROM is a protocol, not a gateway, and it overlays on top of AX/25 to provide a network stack. Poking around online, the Linux Amateur Radio AX.25 HOWTO says as much:

“The NET/ROM protocol is an attempt at a full network protocol and uses AX.25 at its lowest layer as a datalink protocol. It provides a network layer that is an adapted form of AX.25. The NET/ROM protocol features dynamic routing and node aliases.”

So what is NET/ROM?

Suddenly 3 Years Later…

I’m not going to lie, when I last posted to my blog, I didn’t think it was going to be 3 years until I posted again. Time flies at an amazing pace.

A big part of that was due to the Covid-19 pandemic and shortly after my last post it exploded in Australia and borders were closed and some time after that essential movement only. It wasn’t until mid 2021 and after vaccines that things started to open up again.

You would think this would have been a good time to play radio, however with all my gear hidden behind things and propagation conditions yet to improve, my interests lay elsewhere at the time, in video games and storm chasing.

The latter half of 2021 also allowed me to use my health insurance for the first time and a ride in the back of an ambulance thanks to the acute onset of kidney stones. While recovering from surgery and a subsequent stent I was introduced to the game Destiny 2, and so began another obsession that has consumed my spare time since.

It’s rare for me to get so invested in a video game, but the rich stories and lore, game mechanics, crafting and game lay along with having an amazing clan to play with just hits all the magic buttons for me.

All that time though amateur radio still hasn’t been far from my mind and certainly plenty of cajoling from fellow local operators has seen me gradually get my gear operational. Probably some of the notable radio things I have had going on include:

  • Purchasing an Icom IC-9700 to give myself easier access to 2m, 70cm and 23cm
  • Participated is several contests, including RD and VHF/UHF Field Days
  • Placed a dedicated small form factor Windows workstation in for the shack operations

During late December 2022 everything started coming together though and I am now starting to get back on air – mostly with FT8, which I can easily control out of my office. I am finding it amazing how much FT8 has taken over and how much the propagation continues to be active on the higher bands past midnight in some cases now.

Seems like a perfect time to start getting back into the hobby.
