Re: net group
When does the QRP group get together on 70 and/or 40 meters? I would like to join a group. Ron Hi Ron, Here are some resources: 1. QRP calling frequencies are often monitored by operators running low power. The link below has a list of frequencies by band and mode. This gives you good places to cal...

Re: thoughts on band scopes
What are your thoughts on full break-in or qsk operation? How important is that feature to you? I am newer to CW operating than many (about 3 years into my CW journey now), and it would be good to have others comment. Here are my thoughts. Semi-break-in can be an advantage when sending in crowded c...

Re: thoughts on band scopes
How useful is a band scope for a CW only operator? Any and all comments appreciated. Thank you. Personal opinion: It depends how you are operating. For hunting DXpeditions working split, a band scope can be a great help in finding where to position yourself among the callers. For contesting, a band...

Re: Recorded Morse classes?
I’m struggling to make my LICW classes due my shifts and the time difference (UK based ) Are there any recorded CW classes (from anyone) that I can work my way through on YouTube? Something that builds on the class before and has an instructor talking you through? I have a basic understanding of th...

Re: Wet weather antennas
Hi Andrew, I use wire antennas for my QRP work. I did one outing with my antenna exposed to steady rain (I sat in the truck with feedline running in through the door seal after a generous drip loop). I noticed two issues. First, it was the only time I recall having RF in "shack" issues whi...

Re: KM4CFT Antenna kit 30/17 meters
Hi Folks, please excuse my ignorance on this but several weeks ago Tom did a review/activation on the KM4CFT EFHW/EFRW antenna kit where he was able to activate most of the bands from 40-10 using this antenna kit with a 30M and 40M link. He was able to to use the 30M wire to activate 17M. I current...

Re: 9:1 unun 20m
I want to use my 9:1 unun with my 20m QCX mini. What length wire recommendations? 9:1 ununs are typically used with random wire antennas, which are intentionally non-resonant. So, you would need a tuner to match the antenna to your QCX. An advantage of the random wire is its ability to be matched w...

Re: Battery for QRO operations
Hi Matteo, The LiFePO4 batteries that I use have a built-in battery management system (BMS) to protect the battery. In addition to a low voltage cut-off (battery charge expended), they have a high current cut-off. If you draw more than the rated current, the BMS will shut down the battery. After pro...

Re: Best Practices for an EFRW Setup
Mike, you're looking at it just from the point of view of "nasty effects during transmission", that isn't the only way, let me expand it; first of all there's nothing like "power levels" when it comes to common mode currents, the point is that a feedline (coax) should work as a ...
