Quartzfest Update 2025

I delayed my departure for Quartzfest to ship the remaining assembled launchers from the current batch which were nearing completion. Unfortunately they all failed pressure testing and it will require more time to remedy than I have now so it will be addressed after I return from the trip. It appears that the latest batch of pressure relief valves is leaking. I’ve never had such a high failure rate for pressure testing. The kits in this batch which were already sent out used safety valves from previous inventory which did not have the problem. The pressure relief valves can be disassembled and cleaned and we have some instructions for doing that online if you find a similar problem. Hopefully a cleaning will work here, otherwise they will all have to be re-ordered and replaced.

I hope to be at Quartzfest in a couple of days, it is a long drive. Hope to see you there!

My apologies for the lateness of this batch, it has stretched out longer than expected. We plan to start another batch later next month. They fill up fast so make sure you are on the notification email list. Drop me an email if you need to be added to the email list.

Pacificon and Launcher Batch

Thanks to all that put in orders in the recent launcher batch. We have been busy making parts for this batch of orders and will start shipping in a few weeks. Now we’re taking a break to prepare for Pacificon which is this weekend. Dawn will have her jewelry booth near Elecraft on the back wall and you can find me around there from time to time, and I’ll set up at the flea market on Sunday with some flea market stuff and some launcher accessories. I have a K3 to sell, among other things. On Friday I’ll be at the Antenna Forum. There is always something to learn about antennas.

One special feature of the current batch of launchers is that we’ve moved to PETG for the parts on the launcher. This is primarily to avoid problems at high temperatures such as inside a vehicle on a hot summer day. We still do not recommend leaving the launcher in a hot space, but PETG will handle more heat than PLA which is the most common 3D printed plastic. If you have one of our launchers that becomes damaged from heat contact us and we can review options for replacing the damaged plastic.

The next batch of launchers will be made early next year after Quartzfest. We hope to be at Quartzsite this year for the fest. Hope to see you there. After QF we’ll start another batch of launchers. If you want to be on the notification list please let me know to add your email to the list. The batch orders fill up pretty fast, so be ready when we get there. The pattern we seem to be settling into is two batches per year, one early for Field Day, and one late for Christmas. We never know quite how long a batch will take with the variations in the supply chain and the availability of our effort, but every order is filled or refunded, even if it takes longer than initially expected.

Pneumatic Launchers can be repaired or refurbished, as long as it is one we built or one of our kits. Recycling the parts is better than adding to the landfill.

April Launcher Sale

We are opening the catalog for the next batch of our Original Pneumatic Antenna Launchers. The quantity of orders in each batch is limited, then these catalog items will revert back to out of stock in hours or days.

These products are individually made after receipt of paid orders, they are not off the shelf items. The making process may take up to several months. The goal is to ship these orders before Field Day. Some orders in this batch may not be done in time for Field Day. Kits will be done first, then assembled units.

Printers are making parts now. Some parts are in house, others will be ordered soon.
