I did a little research. Many rock-bound CW QRP or QRPp kits come with crytals around 7.030, 7.040, or 7.110.? My Two Tinned Tunahs came with 7.110 and another I forget.? The March Buildathon and

Rex isn't kidding. I've built a few TT2 transmitters that way. Be thankful for the lip and up-top connectors. In the pic, you can see a Rex Super Tuna, an updated (aka toroid version) TT2, and an

Rex, The big three Ham manufacturers have nothing on your tuna cans!? Thanks for sharing and thanks for the history lesson! Davey - KU9L

Dave & Gangue, The new Sea Sprite+ kit will come in all sealed up in a 401 size can....with a special label. Short lesson on cans for QRPme proto boards is here: http://qrpme.com/pages/TCPCBS.php Back

Rex, Does the kit still use the large-size Dole can? I see in your video it is about 2" tall, but our local Walmart either had the skinnier cans or the 5-6" tall variety. I am learning about cans more

Ordered and I also received my desoldering iron today with 3 spare tips. My XYL Ham is accusing all of the kit builders of putting something addicting into those kits!!!!

Gangue, I was wondering why nobody ordered an RF Probe kit from me in a long time even after all the RF Probe emails that flew around a few weeks ago. I went looking for them, as Ihave more than 1

Gangue, While Dan has been keeping you all aware of my upcoming Buildathon, I thought you might care for an update from me directly. This will be the 9th & 10th live streamed Buildathon I've done in

Daniel, I used the AD9850 DDS. I have attached pictures of the board and the circuit for the pixie. The firmware I would have to track down. I did the CWOPS Basic course a couple of years ago. It

I ordered. That weekend is only a few days before we leave FL for the weekend, We will be in IL for 2-3 weeks before we head to Colorado for the summer so worst case we will make it a buildathon with

Hello John,I am learning via Long Island CW Club.? I recommend the club for CW newbies.? They have 1-hour zoom meetings where you can see and hear other hams - CW students - learning the code.? And

Chuck, It may have tweeked back. A previous power reading was .56 watts which matches. That calls into question the accuracy of the watt meter at low values. Have to set up some standard tests maybe

Daniel, I built the Sea Sprite a few weeks ago. Nice build, clean harmonics. Power about .54w as measured on one of my wattmeters. I have register for the buildathon and ordered the kit. I will have

John, Your scope indicates an Vrms value of 5.14V. If you trust the accuracy of the scope, the power would be 528mW. When dialed up it showed .74w into a 50 ohm dummy. Enjoy, ---John AC9UV

Hello, By the way, I ordered the March 2023 Buildathon's Sea Sprite+ kit.? ?I still need to register for the event though. I have some comments and questions on down. Has anybody else ordered this

John, Very nice.? Thanks for showing us the screen shots.? It is an inspiration for others. I like the nice sine wave.? My TTT has 2 peaks. Another ham suggested I use the pot to turn down my power

Group, I played around with my TT EZ-build and replaced the final with a 2n2222a in a T0-18 case with a heat sink. I think I had the original transistor in wrong so got a much smaller output.

$11.? That is a good deal. I have a Radio Shack desoldering iron I got years ago.? I used it last Saturday to desolder pins I put in the wrong place.? And get rid of excess solder that dropped from

Gangue, I forgot to mention that on their de-soldering page, they have replacement tips for that tool. Pretty cheap. I added some of those to my order. I always like to stash away any specialty items

Rex, Thanks, order in. I have a nice little solder sucker that is from Japan that works well but the timing of lifting solder and positioning the tip has always been a source of humor. ---John AC9UV
