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.

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.

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

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

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: 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
