LIVE streamed Buildathon
¿ªÔÆÌåÓýGangue,
QRPme 2024 LIVE Stream Buildathon #1 W1REX & friends will be hosting a LIVE streamed BUILDATHON...over 3 nights....starting at the end of January. Sunday January 28, Wednesday January 31 and the following Sunday February 4 are the nights scheduled for the 3 sessions centered around building a Tuna Tin 2 40th Anniversary kit. In previous LIVE streamed BUILDATHONS, we have been limited in trying to cram an entire BUILDATHON in a 2 or 3 hour time slot. The builds were done in a rather quick pace in order to get everything into the single session with not much time for in depth discussion on the what and why. This BUILDATHON will be much different. Each session will focus on a different aspect of the process.
Sunday January 28 5PM EST Objectives: WHY QRP, TT2 circuit operation, parts identification & sorting, soldering techniques and practice. We will be talking about all the above stuff then ending with soldering practice building a couple of elementary pieces of QRP test equipment useful after your successful completion of the 40th Anniversary Tuna Tin 2 kit. Lots of time to cover these topics with Q&A encouraged. Additions to the 40th Anniversary kit will include parts & pcb for a simple straight key, dummy load and RF Probe. These 3 items are much simpler than the actual TT2 transmitter so easier to build. They will make good starting points for those learning to solder YET very useful when checking out your completed Tuna Tin 2 transmitter.
Wednesday January 31 8PM EST Objectives: BUILDING a QRP kit! Since you now know 'everything' about the Tuna Tin 2 design and how to solder, we get to work and actually BUILD the kit. With 37 total parts, this TT2 kit is a relatively simple to build and should be able to be completed in one evening. We will take it slow and since this session is not in another event's time window, we should be able to take it slowly so that everyone should be able to keep up....now that you are ALL experienced solderers....
Sunday February 4 5PM EST Objectives: Getting everyone's kit up & running and testing its performance. We will have the whole session devoted to getting EVERYONE's kit completed and running as expected. We will learn how to use the key, dummy load and RF Probe to debug and check transmitter performance. We will be LIVE streaming this BUILDATHON from Stephen, N1SH, Houser's QTH and will have plenty of time each evening to get through the objectives. It will be broadcast on my YouTube account (Rex Harper) and on Charlie ¡°Red¡± Brown, NJ7V, (Red Summit RF) Podcast channel. All 3 sessions will be archived on those sites immediately after their broadcast so latecomers will be able to review any missed material.... Times will be 4PM EST on the Sunday sessions and 8PM EST on the Wednesday session. All kits will be shipped via USPS Priority Mail so US and Canada orders should have ample time to arrive on time. DX orders are a little iffy unless they are ordered ASAP.
Stay tuned to this product page for more information as I will be posting lots of pre-Buildathon information before the 1st session. Website: Buildathn page:
Hope to see you there! Rex W1REX |

Hey Rex, 1. Is this going to be during a QSO Today Academy?or a virtual HAM Expo or is it in another format. 2. Is this Xmtr output freq crystal controlled or does it include some sort of VFO? Thanks, Mike KG0P On Sun, Jan 14, 2024 at 2:07?PM Rex Harper <w1rex@...> wrote:

Rex,
Are you including a 7.030 or 7.060 Or 7.112 MHz crystal? No worries, I have an abundance of each & I saw you may be including the 3-pin socket so we can swap them out. I have had my Super Tuna II 95% assembled for some time now & was looking forward to finishing it this winter, but my Ham XYL took a tumble in the RV to obtain a spiral fracture of her right humorous. Mostly now we only go outside to go to the SSA, Drs, or the Surgery center, otherwise it's 24/7 tending to her basic needs since she isn't left handed unfortunately. Learning to cook & do the housework & laundry has me just where she wanted me in the first place, lol. She pulled the ole For Better or For Worse, clause. But, she said I can do the online Buildathon since I have been a Saint for 8 weeks now. She is exaggerating of course. Whether 250mw, 350mw, or 500mw output, I plan to pair it up with my IC-75A communications RX with 250Hz 455Khz IF filter to drive my 66' 49:1 EFHW before we leave FL in April. If I remember right, this circuit pulls a couple Khz down in Freq so putting it on 7.058 MHz? actually is close to my typical POTA QRP 40M hangout. Cheers, Davey & Sheila --KU9L & KB9YYI |
¿ªÔÆÌåÓýMike, This is not through any other entity. I will be broadcasting it using my YouTube broadcast account and Red sill be streaming out of his RedSummit RF podcast. The TT2 is crystal controlled so no VFO. REX On 1/14/2024 4:49 PM, Mike - KG0P
