Re: QRP Transceiver Comparison

Thanks to all for the detailed replies! It's nice to have folks available willing to share such a vast base of knowledge. As I suspected in the beginning, it indeed does seem like a no lose scenario between the TR-35 and QCX+. One more question - Should I decide to start with the QCX+, what single ...

Re: Linked End Fed Halfwave Antenna

A related question: As pointed out, an EFHW is resonant on multiple bands. For portable operations, where deployment conditions might vary, is it safe to trust the SWR will be as it should, or is some sort of SWR indicator recommended?

Choosing battery size

I’m about to receive my first portable QRP rig—a QCX-mini—and am battery shopping. Specifically, I’m stuck between two Eremit LiFePo4 models (I live in Europe), 2 Ah or 4 Ah. I’m drawn to the compactness of the smaller one, and it appears that it can power the QCX for several hours. But I’d like to ...

Re: My portable setup

Thanks for the inspiration -- you've got me thinking about 'shack on a board' possibilities. (What about leaving some empty space on the cutting board for making a picnic sandwich? OK, maybe keep the food and electronics separate...) The way you've repurposed old gift cards is especially clever and ...

portable antennas for 15, 12, or 10 meters?

As the sunspots start bringing the high bands back into play, I'm curious about preferred portable antennas for 15, 12, or 10 meters. Do the compact sizes at these frequencies invite any designs that might be too long or bulky for portable use on the lower bands? Or is the EFHW still king? (Let's as...
