This was a fun little project – and it gave me an idea for a future one. Sometimes, I find that the more complex undertakings, which require more planning, can get to the point that they “take me over” somewhat. At that point, for me, some of the fun starts getting squeezed out and that, […]
Note – lots of photos, so please allow time for them to load! In a previous offering, I posted a few photos and a brief description of a QCX 5W CW transceiver from QRP Labs that I recently assembled for Fred, a ham friend. It was fun, because I got to assemble and experience first-hand, […]
Note that although the audio processor described in this article is intended primarily for Part 15 AM broadcasters, and perhaps also low power licensed AM broadcasters on a budget, it may also have applications for hams with their AM endeavors. I’m thinking of the AM enthusiasts on 160, 80, and 40. Some of them are ex-broadcast […]
The original intention wasn’t to write a post about this, but seeing that I’ve been absent from blogging for a while, I thought there was no harm in putting up a few pictures of the kit I just assembled for a friend. He’s been having a rough time recently with his health. As an experienced […]
Bob W3BBO and I have been communicating via e-mail for a couple of years now, and I’ve been meaning to write this post for quite a long time. I’ve been on hiatus from home-brewing, and expect to be in the future too. The brief run of Manhattan projects I built was really fun, but I […]
Lately, I’ve been thinking more and more about how the K2 is not going to be available for ever. As a literal statement, it is obviously true. I suppose it would be more accurate to say that with the way that a few of the original leaded components in both the K2 and some of […]
I’ve added a few new tools and construction aids to the shack here recently and would like to pass the info on to you, in case it is of any help. The first is nothing out of the ordinary, but I’ll include it here, if for no other reason than the excellent instructions that were […]
The WBR seems to get a bit of a bad rap with some people for it’s sensitivity. A comment on the last post from a reader called Simon, reminded me that some WBR builders have experienced poor sensitivity. Based on my experience, this design does seem to be fairly deaf on AM, but the sensitivity […]
Occasionally, I drag out old projects from their resting and display positions on my shelf, plug ’em in, and give ’em a whirl. It’s fun to watch as past home-brew rigs come back to life, and relive the feelings of wonder, as a handful of parts that I soldered together actually receive signals and in […]
I’m a very casual operator, and an even more casual portable operator. My main reason for not putting much effort into portable operation is that when I go out into nature, I want to enjoy my surroundings and not be distracted by radios. It sounds like an excuse, but it’s true. I spend quite a […]
