The QRPer Board

An easy, simple rule of thumb that I learned helping my dad back in the 60s:

At least a quarter-wave on the lowest band you plan to work.
Not a half-wave on any band you plan to work.

How did it work for you?

The whole setup, except for the LPF is home brew. Antenna, radio, crystal switching board, even the key. My goal was to show what I was doing. I wasn't asking for suggestions to improve it or to build my own stuff. I can look up internet posts and repost them also, but I would much rather see what y...

With this setup, my big goals are simplicity and very small size. I want everything to fit into an old eyeglasses case, including the antenna. I want to pull it out of my pack and be on the air in minutes. And it needs to pack up in minutes. I'll find the resonant points on the wire and put knots th...

I finally got out to the park for first time this summer. I only had my homebrew QRPp rig, an EFHW cut for 40m and a 9 v battery. I did work one of the 13 colony stations, but everything else was just hits on the RBN. I need to get out with the analyzer and find the other 06072024 qrpp.jpg resonant ...

Anyone doing the 13 Colonies special event using QRP?

I usually work 7 or 8 of them every year. Things are lining up that I can put a real effort in this weekend.

I hope you all have a great 4th of July!

I enjoy going to the local parks to play radio. I don't drive, so getting to parks for POTA are too far away. POTA is boring to me anyway. Like shooting fish in a barrel using a $30k bass boat. I try calling CQ, but if I'm not on the spot page and showing up on their waterfall, no one bothers to ans...

It shouldn't matter, as long as the connection to the tuner or radio is made with the winding not between the wire and radio. That means having uninsulated wire if the winding is at the near end. Having the winding at the far end will have little or no effect.

Todd The winder is always at the far end of the antenna. Most of the time, I use a telescoping pole. For the times I'm forced to use a tree, I just throw the near end of the wire over from the opposite side of the branch. I really hate using trees in public parks. My wires are light enough to use co...

I devised a winder frim an old gift card that lets me lock the wire at any length. I put knots at the resonant points of the wire so I can work any band. The points allow the wire to spin off very quickly. The "ears" and notches catch the half- hitch knot I lock the wire with. Loop.jpg win...
