“Don’t you remember?” –Starship, “We Built This City”
Haven’t done much radio stuff in the last week or so, except for finally getting on the air with the group of locals I hear on 146.52 – one of them was demoing FT8 for another on 10m, and I replied. When he said on 2m, “man this guy is loud” I finally found my comfortable opening to key up and say, “I should be, I live two blocks away from you.” Laughs were had and I found a group who was quite welcoming to my presence, we all chatted for an hour or so before turning into pumpkins.
The other big thing I did was bit the bullet on a virtual table top license for Foundry, and started setting up the campaign I ran with the kids before using the Lost Mine of Phandelver module from the D&D starter set. Already I’m more comfortable with some of the things I’ll need to do as a DM, and the only reason we haven’t started playing yet is because there’s some areas I want to pre-stage before the kids might decide to go that way instead of towards the main storyline. Of course I could fix that by asking them if they’re sure that’s how they want to go, and if they say yes then I close the window and say “then you’ll have to wait until I finish setting it up, now get ready for bed.” 😀
“When I’m on the mic, the suckers run.” — The Beastie Boys, “The New Style”
Back when I first started doing DJ type work, I picked up a microphone from Radio Shack. That Realistic Highball-7 has seen a lot, and when I started using a mixing board for amateur radio work I plugged it in and gave it a slider as “Desk Mic” for sitting on the keyboard tray in front of me so I could work hands free without the headset. But since my headset was starting to show signs of wear (the right speaker is “crunchy” due to a broken wire in the crossover from left to right) and I was going to get new headphones anyway, and since not only am I using the mic for radio work but now every day for work I use it in meetings, I decided it was time to upgrade to the Right Stuff.
So I picked up the Heil PR-40 that I’ve wanted for almost as long as I’ve been a ham. A kit from B&H included the mic, an Auray boom, shock mount, and wind screen all for less than the sum of the parts. At the same time I did some research into headphones and found that of the two best ones on the market for general use – the Sony MDR-7506 or the Sennheiser HD-280 Pro – the Sony had a slightly better rating for breathability when just about every other metric measured was the same. This tells me that after a long day of wearing them, your ears will feel more comfortable with the Sony than with the Sennheiser, even though from all accounts they’re almost equivalent in likability. So they went in the shopping cart as well, and now I have a nice pair of studio cans to go with my broadcast-quality microphone. It’s even getting me to make more SSB contacts because I *know* that sounds better than the old Realistic microphone ever did!
When I first thought about taking my radios portable, I picked up some Pelican cases to store it safely. Those cases have taken my gear from Tampa Bay in Florida to Bangor, Maine and many points in between. I realized one of the latches on my large case (a Pelican 1600) was broken, so I ordered replacement latches. They arrived today and were the complete wrong size. How could that be I wondered… apparently, Pelican redesigned their cases at some point and kept the same model numbers. I have an old one. Who knows if I’d ever find a replacement latch at this point. But two things are keeping me from bothering too much now: first, I don’t use the case in marine environments where I’m concerned with water ingress, so the fact that the one side doesn’t seal as tight isn’t much of a concern for me. And secondly, that latch has been “off” since day one – it always required that you smash it just right to close – and taking the pin out of it I realize why. The holes from the left and right side don’t line up, so it was defective at purchase and I didn’t realize it, just thought that one was quite tight. No, it was stretching to reach the edge of the case because the one side is too far away. I guess if I found the right size latch I could straighten the hole on the one side, but I don’t think it’s worth worrying about too much anyway. I mostly utilize the case to carry the equipment safely from shocks and bumps, and be able to stack things nicely.
I mentioned elsewhere about problems I had with my antenna tuner. While nobody asked, I figured it’s good writing practice to sit down and tell the story. Also, then it’s preserved for hysterical reasons. There’s also the fact that this stems from buying a new house and setting up everything in the ham shack all over again, which is a story that might deserve to be told, but at least right now that’ll be for another day.
I alluded before to a problem with my antenna tuner at home. To not tell the long story yet but get to today’s point, it’s on the way back to the manufacturer to be diagnosed and hopefully replaced. Meanwhile I took the old unun (which is a 4:1 transformer that connects the coax from the transmitter to the two points of the antenna, the radiating element above ground and the ground radials) and mounted it back on the antenna. Kept my homemade RF choke coming off the feedline, and connected the other end of it into the unun – probably overkill but so be it for now. Then managed to crimp two ring terminals onto a piece of 10ga wire I had laying around from an old UPS, and used that to connect the ground lug of the unun to the mounting bracket so it would ground things properly. Finally went to take the positive wire that mounts to the radiating element and put it on the positive lug, only to find the stud is too big for the ring terminal. Well fine, this is temporary anyway – so I literally sandwiched the ring terminal next to the stud and between two washers, then twisted the wing nut down nice and tight. Hey, it’ll work in a pinch right?
Right I was, when I hooked the tuner up in the shack and found I was able to get on the air quite easily. Even turned the power up to 100W with no problems either from the tuner freaking out or from RF coming back into the shack. Did I mention that since this is temporary I didn’t connect a ground line to the tuner either? Today I got a couple 90-degree PL-259 to SO-239 adapters so I can more easily mount the thick coax onto the tuner, and since I had to buy a four pack when I only needed three I used the third on the back of the radio too just to make that a little easier.
So things aren’t how they should be: I should replace that 10ga wire with a better crimped 12ga one (I failed to mention I didn’t have 10ga ring terminals so I spread the 12ga ones out a little), I should replace the other wire with one that has properly sized ring terminals as well, not to mention I should have my actual tuner sitting there instead of this hack, and maybe when that tuner returns I should put a better choke balun at the antenna feed point either in addition to the homemade one or to replace it. But all that aside… I have a working HF station that maybe even works a little better than it did at the previous house. I noticed during lunch today when I hooked everything up and tested quickly that the noise level on 20m was quite low between transmissions, something I don’t remember seeing here previously and may be better than the previous location as well but I can’t recall. So it’s all still not right, but it’s getting better. Just gotta remember that, it’s getting better.
When I started in amateur radio, I did the simplest of things – used the hand mic plugged into the front of the rig. Over time, I drifted away from radio usage for a bit and then came back into it (that’s a story for another post.) When I did, I started to make my shack more complex and versatile, and even added new radios for more functionality. Now I had the problem of having different ways of talking into different radios, and I didn’t like that as much. So I designed a switch box that could take some inputs and mix up the outputs to make things more convenient for how I like to operate. I had someone on my radio club email list ask about a product that could do a similar thing, and I mentioned that I built one for not that much time or money. Since he was interested in more information, I wrote the whole thing up as a nice article. And now, I present it to you, my Home-Made Microphone Switch.
Recently I’ve started reading for pleasure again – more than just technical manuals and white papers anyway. I asked around my friends about a good place for recommendations for books. Mostly what I wanted was a kind of “if you like those, you may like these” type of thing – rate a few books and get recommendations for things other people have rated similarly. Everyone said Goodreads was the answer to that, so I set up an account there. I don’t have many books in my “read list” yet, mostly ones that either I could see from my shelf at the time I created the account or some that were purchased after that and added in there like the Dan Brown series of books I got since the holidays (which was precipitated by watching the movies not that long ago and enjoying them). Some books from when I was younger, like a lot of Dean Koontz novels, have made the list too. Others I’ll add as time permits and I remember them.
Since Goodreads has its own built-in review pages and whatnot, I don’t know if I’m going to duplicate them here. It seems silly to post in both places, though they do have a nice feature that when you post a review you can get a HTML code block that includes the review and links back to the site and whatnot (which is included below for my latest finished book) so I’ll think about it. Meanwhile, at the very least, this post serves to link you to my Goodreads account, as well as an offhand way to mention I finished “The Lost Symbol” by Dan Brown last night and enjoyed it.
A lot of people seem to crap on Dan Brown for his writing style. I don’t understand the hatred myself – this is the third of his books I’ve read and I’ve enjoyed them all. Are there parts that maybe are a little predictable? Perhaps. But on the other hand there’s the benefit of having your brain draw a conclusion that in the end is found to be false. Maybe you saw it coming a mile away and that’s why you didn’t enjoy it. For me, I enjoyed this book, found a few twists I did not expect and enjoyed, and found it hard to put down more than once when I knew I should be going to bed. I look forward to the next one as well.
I’m starting to get there with the site layout. Adjusted some things, I think I broke some things too, but it doesn’t look half bad. Except the black text in the top bar, I don’t think I like that. Maybe I’ll play with other themes and see if I find one I like soon. Meanwhile, back to the topic of “why are you reviving this”, some information on ideas I’ve got and whatnot. Strap in kids, it’s gonna get bumpy.
I wondered myself. Why do I feel the need to come back here and write again? I used to write on Facebook, though it was always shorter things. And then when Google Plus opened I wrote there quite a bit, and pretty much abandoned my website because the same content on G+ drew a lot more traffic. So why come back to here again? Well, even though I don’t pick up the microphone on the radios that often, I do like to talk. Especially when it’s things I’m passionate about. Tinkering, electronics, these are things that I enjoy a lot. And when I think of a new thing to explore, I like to talk about it to people. Sometimes when I talk about stuff it’s because I need to think it through, and having someone else to listen and especially ask questions is helpful for me to hash out the idea myself or gain a greater understanding. Other times it’s because I want to share my excitement with someone and maybe they’ll want to join in the fun. And sometimes it’s just to make a connection – I find a lot of geeky types are eager to share their geekiness in hopes of finding another geek who likes it, if only to have someone to work with and come up with new ideas. Unfortunately, and especially when the audience doesn’t share in the excitement, that kind of gushing about a new thing can be boring at best, or off-putting at the worst. So rather than subject my family to it all the time, I thought maybe writing about it would help me to still have that moment I feel like I need where I talk about something that has sparked in my head, without forcing others in the house to look for a way out of hearing range 😀 But first, I still need to do some housekeeping around here. The cobwebs are a bit thick, and there’s definitely a layer of dust everywhere. Only I have a couple things I’m working on that have prevented me from working here, so we’ll see how it goes. Maybe I’ll start writing those things as drafts to share later, so I still get it down to publish without making it seem like I’m ignoring the mess everywhere…
About five months shy of ten years since my last post on this site. Why? Well, for a while I was writing more long-form stuff on teh Plus of Goog, but they eventually went away. Then I caught some flak for posting things that some people felt I shouldn’t be posting, so I retreated into my own little world of not saying much of anything, certainly nothing controversial or even vaguely pearl-clutching. But I keep finding things I want to write up or talk about, and teh Book of Face isn’t the right audience more often than not. Sure I could go with Medium or something like that, but… I have this domain with WordPress installed, why not use it? So I think I will. Soon. Gonna fix up the place a bit first, and clean out some cobwebs.
