Re: Ordered my March 2023 Buildathon's updated Sea Sprite+ kit with coupler, key, and Zepp - I have comments and questions
Chuck, That is why I mentioned it. You cut off 17ft for the CP and the rest is the antenna. Nice way to give you both and not need a feed line. ---John AC9UV

Rex is including a counterpoise. There are No-Tune sources who are expecting coax to be the counterpoise. Connecting direct to the V6 kit cuts out feed line. Sent: Wednesday, February 22, 2023 4:18

Based on feedback from Chuck, the antenna for the Sea Sprite+ with built-in No-Tune antenna coupler is designed to work with an EFHW (End Fed Half Wave) antenna.? ?The antenna included with the Sea

Daniel, I have only had the experience with the AD9850 DDS in making the VFO project. It went together well and has been a solid stable frequency source for my projects. Also in building various

John, Very cool.? I want to home brew my own VFO.? I will eventually.? I have all the parts to build multiple VFOs using Si5351A (module or chip), LCD, rotary encoder, and a microcontroller (chips

Re: NEAT tool..
John, This procedure works exactly as shown, the smaller the screwdriver the better. Actually, I had more of an issue putting it back together than I did taking it apart (as usual!). How to open and

Re: NEAT tool..
Rex, Just got that nifty tool. I read the instructions but getting the cylinder out to clean seems to be stuck. Not wanting to force it. How is it best to do that. I thought of a screwdriver between

Re: Band Frequencies for QRS (Slow Code), CW and Morse Code Newbie Hams, and Typical Frequencies for Rock-Bound Kits
Oh, yeah--Daniel--? If you haven't tried 7055 kHz, most of the ops there don't go very fast--usually more than 5WPM, but I've heard 10WPM or slower, too. You don't have to stick to 7110-ish for speed

Re: Band Frequencies for QRS (Slow Code), CW and Morse Code Newbie Hams, and Typical Frequencies for Rock-Bound Kits
Daniel-- Short answer: Anything your license will support. Why? When I was a Novice (Tech +, actually, but still a novice operator), I loved the 40m Novice Band. It was years later, as a General or

Band Frequencies for QRS (Slow Code), CW and Morse Code Newbie Hams, and Typical Frequencies for Rock-Bound Kits
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

Re: short lesson on food cans
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

Re: QSO Ham Expo Buildathon
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

RF Probes
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
