Picture of QRP-ARCI FDIM 2020 Buildathon


WELL! It is official. Dayton Hamvention 2020 and ARCIs FDIM have BOTH been cancelled due to the virus and public gathering restrictions.
I will be attempting to continue efforts to host the FDIM Buildathon via LIVE streaming it from here in Limerick. Stay tuned for further details as they develop!


I did a live stream Buildathon way back in 2011. We streamed it from the FDIM hotel media room with the help of Steve Fletcher & BATC. It was a while ago so the details are a little fuzzy but if I remember correctly, we had 18 builders in the room and another 40+ builders around the world and another 20+ watchers. It was a last minute thing but we pulled it off. I have 2 months to figure out how to do a better job so I am on the case! Our library here in Limerick has a full video streaming system as part of the inter-library education network. I will be checking in with the town librarian this week to see what we have and what else I need to pull off the event.

So there will be no more Buildathon seats or limit on builders or picking up of kits. All kits will now be sent in time for them to arrive wherever they need to go before the date of the Buildathon. If you are interested in the LIVE streamed event, You had better put your oar in early. The kit has parts that are rather unique and I have to buy them early and in bulk to get the best price....and make sure they get to ME in time to get them into kit form AND get them to you in time!

This year we will be building a QRP Glowbug. This kit will be an updated version of the PP2 twin acorn tube design by GM3OXO.



The original GM3OXO schematic from SPRAT #112 can be found below. Yes! If you closely, you might find a couple of errors in the schematic. They were brought up in following issues of SPRAT and I have that under control. Hopefully, the working prototype will be finished sometime this week and I will post new info as it is developed..

I kludged up a box just for illustration so you can see what I am seeing. I could not turn up any 955s in my cavernous junque box but I did find a pair of 9004 acorn diodes with the same heater voltage. I used those in the Kludge pictures. Later I found a single 955 in a piece of Priceless Antique Radio Equipment so I hosed it up to a power supply and took a night shot of that. You can see that it is definitely a QRP Glowbug!

Since there is no Buildathon room and everyone will building at their QTHs, there is no limit to the number of builders...except the practicality of kitting and shipping them. I will start the list and 40 and see where that goes...
