W6LG on SWR
Standing wave ration (SWR) is arguably one of the most debated—and misunderstood—topics in amateur radio. Here is Jim, W6LG’s, take on it.
CW without Morse Code?
In amateur radio, we tend to use the terms “CW” and “Morse Code” interchangeably. Technically, though, we send Morse Code using continuous wave (CW) transmissions. CW could be used to send other codes, such as the one proposed by this video.
It doesn’t’ seem like the code proposed here is all that practical, but YMMV. Let me know what you think.
MONTV on impedance matching
Impedance and impedance matching are two more misunderstood topics. Here, Nick, M0NTV, explains some of the basics of LC matching networks. What good is knowing this? Well, for example, if you really want to understand how your antenna tuner works, you’ll want to watch this. This is Part 1 of 2 videos.
Hello Dan, the video about T9 code is really interesting. Is it really easier to learn compared to CW? I probabely going to try. 73, Bas
Hi Bas
The T9-code might be easier to learn and remember, if you are familiar with T9, however the code is very inefficient. International Morse was designed so that the most used letters (in English) have the shortest code. That’s not the case with this code (I have included a few examples in the comment of the video).
I agree with W6LG. It’s worth adding that most modern radios with solid-state RF finals will automatically reduce transmit power if they sense high SWR. Older solid-state radios without the foldback feature can be vulnerable to high SWRs in certain circumstances. Tube radios are generally more forgiving.
