The QRPer Board

Gene -- what a coincidence. I just got the FedEx notice for my QMX yesterday! (Deliver is expected next week.) I'm not sure what power supply I'll use, but I will be careful. The operating manual states, "The supply voltage range for QMX is 6.0 to 12.0V. Maximum power output depends on the supp...

I use that brand (50 Ah version), two of them in parallel, in my shack. I use a different brand (same chemistry), two 20 Ah in parallel in a Harbor Freight box for portable operation. That portable box works great for me for picnic-table style POTA operations. With my IC-7300 at QRO levels and my st...

I've run my SW-3B on LiFePO4 voltage (13+) just fine.

Hey everyone, I'll be in South Carolina near Hilton Head for the first weekend in August, and there's so many parks to activate! Are there any special considerations for operating on an east coast beach? Optimal times of day or antenna deployments to reach Europe? Is vertical my best bet? I should ...

Same boat ... I'm 2/3 through building a QDX, but went ahead and ordered a QMX anyway.
So much to do ... so little time.

Brian -- looks like it's sold. However, there's another guy also getting rid of his. I'll see if I can find his contact info and post it here.

Brian -- I'll have to check. It's on loan to someone who wanted to try it for a while before buying it. I'll check today.

Rick N8TGQ is right. There are lots of boards printed with "QRPguys," including those sold on amazon, that are not made by QRPguys. It's really shameful. Also, that style of board (with a copper ground plate incorporated into the winder) seems to have some quirky performance. There was a t...
