Here's the link to my report on the 9:1 antenna build from over at QRPer.com:

Thanks Andrew. Further details on the antenna build are coming soon, and I will link them here after they are posted. In a sneak peek, I had 3x17 ft ground radials deployed at the feedpoint.

My reason for building this antenna was 2-fold. First, I wanted to prove out the QRP-level 9:1 unun design. I am satisfied with its performance. Second, I wanted to assemble a field antenna that would let me use the 160m band. By pairing the antenna with a wide-range tuner (in this case an LDG Z-11P...

Thanks all! I am going to build a QRP 9:1 using tri-filar winding, and no capacitor. I'm not yet sure about radiator length. All I'm lacking now is a bit of shop time. When I get things together, I will let you know how it works. Best 73 de Brian - K3ES I finished my build this month, and used the ...

When I power up my TR35 on 20 meters it always starts on 14.262 in the phone portion of the band. The other three bands always start at the bottom of the CW portion of the band. It's not a big deal, but I was wondering if that is the nature of the beast or if there is a fix, maybe a firmware upgrad...

Question. What type of connector do you use for linking this antenna? I just built a copy of the K6AEK 49:1 and 9:1 Unun. Very small to use, I just want to add a quick connection to the output of the Unun to try different length wire elements. TU in advance and 73, Jeff K9JP Hi Jeff, First, whateve...

Yaesu apparently alerted their dealers that FT-818ND (and also FTM-400XDR) production will be discontinued due to parts supply problems.

How much do you trust that an EFHW will have good SWR when using a rig that doesn’t show SWR such as the TR-35. I’ve heard people say that they don’t worry because the ant supposed to be resonant on 40m & 20m. I’ve always used an ATU when using my TR-35. Max - WG4Z Hi Max, I home brewed the lin...

Thanks, Skip.
