A Tale of two QCXs

As you may know, I am a Ham Radio operator and that, among other aspects of the hobby, of which there are many, I do two things. I operate QRP (low-power) operation, mostly CW (Morse code) and I like to build electronic kits.

Ugly on the left. Beauty on the right.

Sometimes those things cross over.

A while ago, probably more than a year, I became aware of a neat little QRP radio kit called the QCX. It was offered for sale by a German Ham, living in Turkey, for only $50. It was a single-band, 5 watt CW radio that was pocket-sized. Slightly bigger than a pack of Canadian cigarettes.

There have been many small, inexpensive QRP radios before. I have a few. But this one was built around the little microprocessor chip found in the Arduino boards. It had a display, and the chip allowed it to do a lot of neat things that usually took place in outboard boards. For $50 buck, I had to try one.

So I did and I wrote about it before, so I won’t get into it too much. Once it was done, it needed to be put into an enclosure. So I decided to fit it into one. I got an extruded aluminum box that seemed to be the right size to do justice to the small size of the radio and I started doing what needed to make it fit inside.

Let me tell you, it might be aluminum, but extruded aluminum is tough. Tough to work on. drilling holes wasn’t too bad, but cutting big openings for the display was hard. Then there was the challenge of making the controls work. The push buttons were tiny and needed some kind of extension to reach out of the case. The two knobs – one encoder and one potentiometer, were at different lengths as well. I had to fabricate extensions for all those with my limited machine shop. (Hand tools.)

When it was done, and working, it was crude, but did the job. I built it for 40 meters. Naturally, I wanted another, so I bought on and built it for 20 meters. This time though, I bought the matching case from another company that made them for Hans.

It took a while to arrive, but came after I had completed building the second kit. It looked fantastic. I was happy that I spent the extra money rather than struggle with making my own case.

Fast forward a year. Hans, being ever busy and industrious, improved his radio and replaced the QCX with a new model called the QCX+. He also came out with a even more compact version called the QCX-mini. The plus is bigger and easier to build. The mini is smaller, comes with many surface mount components pre-installed and to make it smaller, he came up with a scheme of nesting circuit boards that increased the density while still being easy to build.

The writing on the wall, though, was the the company that sold the cases probably would not sell them forever. I decided to order one and put my original kit in a proper case to match the second one.

I ordered it in November. Then COVID hit and disrupted the world’s shipping. The first one was slow to arrive, but not unreasonably so. I patiently waited for it, but I began to fear it had gotten lost. They were shipped without tracking to save cost, so there was no way to tell. I emailed the maker, Markus, but received no reply. I imagine he got so many inquiries that he stopped responding.

So, I gave up on it. I actually went ahead and ordered two of the QCX-minis with matching cases and planned to build one of them to replace the 40 meter QCX. But they won’t be available for a while.

Then, out of the blue, the case arrived today. Hallelujah! Heere’s some photos of the transformation from my ugly box to a beautiful QCX that matches my 20 meter version.

Out of the old case. Seeing if it fits the new one.

Front. Board. Rear. Almost ready.

All done! I decided to keep the oversized knob I added. Maybe I’ll get one for the 20m version.

Almost twins!

A new Radio for my shack

Well, I’ve been getting back into Ham Radio lately. With the pandemic stifling most things that are fun, I figured it would be a good activity for being social distanced. Little did I know which way it would go.

I had a good radio, my main radio, which served me well for over 20 years. I used it in many contests to make thousands of contacts over the years. I didn’t scrimp on it, I spent until it hurt, which at that time was a lot of money. I put all the accessories into it. Over the years, it needed some maintenance. It had a battery that died every ten years or so, and when it turned on and said “TILT” this time, I assumed it was time for a new battery.

I ordered a new battery, a li-ion coin cell. The original was the type that solders directly onto a circuit board. It’s hard to find the exact right one of those, but I ordered a holder as well. I figured I’d put the holder in once and from then on, changing the battery would be a snap.

But I put it all in and it did not fix the problem. I looked into the feasibility of sending it out for repair. I had shipped it to a fellow in Texas once before for work. he was about the only Kenwood certified repairman left. I looked him up and his web site said he had retired. But it referred me to a new service place, up in Minnesota, I believe. They did indeed still service my radio. For only $350. Shipping would be about $50 each way. I looked at the prices of used models of the radio, and they were barely getting $500.

I decided that I have had my money’s worth out of the old radio, the Kenwood TS-850SAT, and it was time to replace it with something new. But I didn’t want to spend the kind of money it would take to replace it with an updated equivalent. That would have taken at least $2-3000.

Instead, I lowered my sights a bit and found the Icom IC-7300. it was going for $1100 with a $100 rebate. It’s a modern style radio, a bit smaller th an the old one, but very capable. Many of the extras I had to add to the old radio came built in on it. How do they do that at such a low price? Well, technology. It’s a radio based on DSP – Digital Signal Processing. Most of the work that used to be done by stages of mixers and filters and amplification, is now done by microprocessors.

The 7300 has been on the market for at least 5 years, but I hadn’t been paying attention to it. It still looks like a traditional radio, but with a fancy touch screen that gives you all kinds of menus for settings and different ways to display what it is doing. It also interfaces with your computer, not through a serial port, like the old one did (with a special adapter) but through a USB cable. The computer sees a virtual serial port to control the radio’s frequency and other settings, just like the old radio, but it also acts like a sound card so that the computer has access to sound coming to and from the radio. This greatly simplifies using data modes.

So, I got the new radio and have been having a great time making it work and setting it up. One thing I found, that I already knew, but didn’t matter with a radio that didn’t work, was my antennas have deteriorated to the point of being almost useless. The only one that is even partially useful is my 40 meter vertical and there is something wrong with it, but I can still make some contacts on it. In fact, I’ve been using it on most bands with the tuner built into the radio.

My triband yagi, A Cushcraft A3S, had been out of commission for years. The center, driven element fell off. The U-bolt broke and the whole element came down. I can’t get up there to do anything, so that’s not going to change.

My 80 meter dipole, a high wire antenna that runs from a tree in front of my house to a tree at the back fence, just doesn’t work. All I hear on it is noise. I can see that one end was caught up in some branches and has unravelled, but not fallen down. But there must be something more wrong than that. Maybe the coaxial cable is broken, maybe the balun at the center is bad. It’s held up by ropes that go through pulleys, but the back one won’t let it down because it’s caught up in the tree branches. I’ll have to get up on my kitchen roof and pull the center down by the coax to free it up. But I’m not going to do that until spring.

The 40 meter vertical, I suspect has a bad coax, but I’m not yet 100% sure of that. It’s buried in the ground, and even though it is direct burial cable, that’s only good for so many years. I ran a piece of RG-8X to replace it, just letting it lie on the grass and that improved it somewhat. It’s time to replace the coax in the ground just on principal, but again that will have to wait until spring.

So, I’ve got a nice new radio, but can’t fully enjoy it right away.

F Facebook

Well, I haven’t been posting much here lately and most of my thoughts and rants have been going on Facebook.

They make it so easy, so seductive, to just put a short couple paragraphs or just a comment on someone else’s thoughts. It becomes too easy to spend time there.

But, once again, I’m in Facebook jail.

I don’t know why. They say I posted something that violated “community standards.” They gave me no details and I don’t remember what it may have been. Just suddenly, I can’t post anything. I can’t leave a comment. I can’t even like a photo of a furry cat.

I dug around and found – with some difficulty – a reference to their deleting a post.

This is all I know…

I can’t tell from the little thumbnails what it was, or what about it they didn’t like. I have a “Page” where I post things. Things about Trump, our government, and politics. I started the page so I could keep those things off my personal timeline and let only those who want to read them see them. I was being considerate to those who might be offended by anything critical of our illegitimate president.

And, ordinarily, I avoid anything offensive. I lean towards the ironic, humorous, or satirical commentary.

95% of what I post is graphics – cartoons, memes, photos, and articles from major news sources. I mostly “share” not “create.”

And, yes, it’s mostly anti-Trump, anti-conservative, anti-GOP, etc. because, well, how can any moral, thinking person not be?

So, I am in the corner, getting a three-day time out from Facebook. Like that is supposed to teach me a lesson, whereas not telling me what the offense is does…

My experience with these things (I have known others who have also suffered the same fate) is that you usually get these things as a response to someone’s complaint. They are either processed by some algorithm or some person who reviews hundreds per hour. No deep thought is put into it. And there is no way to get a meaningful review. You can click a box that asks them to look into it, but I have not received a response.

From the thumbnails, I can tell it was a cartoon. That’s about all. I routinely download and keep the images I post, rather than just hit share. I do that because I want to break the chain of “So and so shared so and so’s post where they shared so and so’s…” I also sometimes copy and paste commentary along with it that I think the person may not want to have attributed to them. Public figures, I quote with full attribution, I spare the average friend.

So I checked through my collected images and did not find that one. It doesn’t mean it didn’t come from me, but it’s odd that I did not keep a copy. It might be left on a different computer that I don’t normally use. I only checked my laptop and phone. You can bet, if I do find it, I will post it here!

And, I did. I could not find it on any of my computers, but a couple of them have been reworked recently and may have been erased. But with a little Google-Fu and some help from Tineye, I found it.

That’s it. That’s the “offensive” post. I vaguely remember it. It was quite a while ago, so either they dug deep, or someone is going around looking for that particular picture.

This photo was found many times on Twitter. It was on Reddit. It was on Instagram and Pinterest, so it clearly doesn’t cross any lines for most places. It was totally used to target my account. There was also a version of it with a ghostly figure, possibly Jesus, leaning over 45.

So, I supposedly “violated community standards” by posting a graphic that came from the community. Hmmm…

Looking at the timing of it, where we are in the middle of the peak of the Trump impeachment Senate hearings, one has to wonder if it isn’t part of an organized strategy to use Facebook’s’ policies against anyone openly critical of him? Right now, silencing a bunch of his critics for three days without any hearing or recourse, would be huge. You almost wonder if it’s not a new wave of Russian hackers turning to suppressing criticism instead of posting pro-Trump propaganda?

I don’t flatter myself to think that I am that important, or widely influential to garner special attention. So, the explanation of a widespread organized process makes more sense. I just got caught up in it.

So, Facebook put me and possibly many others in Facebook Jail. I’ll live. Actually a three day break will do me good. After all, it got me back to my long neglected blog…

Frank’s Really steps in it when it comes to the dressing

Local news erupted in horror recently when Frank’s Red Hot sauce tweeted that Ranch Dressing was appropriate dressing to go with “Buffalo Wings.”

It was immediately pounced upon by the Buffalo media and followers.

Of course, runny Ranch Dressing just isn’t up to the job of replacing real Bleu Cheese dressing, as one tweeter recounted that his wife put out some ranch dressing at a superbowl party, and no one touched it.

But this is a long time pet peeve of mine. There are so many things wrong here that I have to set the record straight.
