Next time Rex has a build-o-thon at a conference - start up conversations on this group please


Daniel KK4MRN
 

Hello hams or potential hams who want to build and play with QRP radios.

The next time Rex Harper and others go to build-o-thon sessions at some conferences, can you start up a conversation on this group please?
Blog about?

Take notes, photos, and videos.? And post the notes here as an attachment to a message.? Upload videos to YouTube and link to the videos in a message on this group.? Photos - well, you can attach in email, point to the file section but there is a limit there...? Or upload the photo to flickr.com but I have never used them. And then put a link in the message to the photo on your flickr.com account.? Make the photo visible to the public.? Not sure if there is a limit or criteria on flickr.com

For each build-o-thon, create a new topic and then everyone posts to that topic if they were part of that build-o-thon or they bought the kit and built it from home.

Not only a build-o-thon conference but your own stuff your built recently.? ?I know in the Richmond Amateur Radio Club has people who are put of a Radio Builders Group in Richmond, Virginia.? ?So, see if your club is building anything or suggest to build something from QRPme.com - their kits are low cost, and simple to build and understand.

So, show off those Two Tinned Tuna transmitters you built.?
And show off those Sudden Receivers.? ?
Include accessories and test tools RockMite IIs and amps and tuners.? ?

What contacts did you make?? What antenna did you use?? ?What bands did you chose?

Did you have any issues?? What did you do to fix the issues?? What did any elmers suggest to you?

Did you make any modifications or enhancements to your rigs?

Inquiring minds would like to know...

Thank you,
Daniel Morgan, KK4MRN in South Carolina

Gangue,

OK, here is the very latest news...

I will be hosting another Saturday Buildathon live streamed for the March QSO Today Virtual Ham Expo. The kit we will be building is a brand new updated version of the Sea Sprite transceiver operating on 7110. I have changed the output portion of the kit to a low pass filter with built in antenna coupler. I will be adding a half wave end fed Zepp antenna wire and simple pcb key to the mix. So in a couple of hours, a brand new Technicion ticket holder can be completely on the air on 40m. Yes, they will have to source a 12V battery and some headphones.

I know the Sea Sprite rig is very simplistic and the performance is questionable but I have to start with a kit that can be built by practically anybody in a couple of hours. My hope is that any beginner builder could get an 'hf station' ready for on air operation in one session. Half of the workshop is aimed at getting beginners to build while the other half is the on the air action. I will be pushing for everyone to put their rigs on the air for a mini event on Saturday night and Sunday morning. Possible a couple of hundred exact same rigs & antennas on the same frequency operating at the same time. This is an neat opportunity to get a real handle on whether or not one can actually make contacts on such a rig. In a Sunday workshop on the QSO Today event, we will discuss the mini-event results and then talk about the parts of the little transceiver as to how they work and affect the performance thereof AND possible changes and improvements.? Should be fun. More info as it develops....

Hey Rex, a moderator has the ability to separate messages into a new topic.

Would you like to make this a new topic starting with yours for the brand new Updated Sea Sprite and the March 2023 QSO Today Virtual Ham Expo?

I am guessing you will link to a kit on qrpme.com for this kit when it is ready?

I am curious about the RF Power Output.? Will it be similar to the current QRPme Sea Sprite?? I think heard another ham got 0.680W output on the currently sold Sea Sprite.

The QSO Today Virtual Ham Expo is the first and only on-line amateur radio convention, since August 2020.? ?
For more information on how we do what we do, PLEASE SCROLL DOWN THIS PAGE
Event tickets and registration cost $15.00 per person for the Expo weekend and 30 day on demand period
