Back to the Mac

My wife and I have an annual tradition of buying ourselves something around Christmas each year. Not only is it Christmas, it’s bonus time at the company where I work. These things frequently take the form of electronic gadgets.

This year, my plan was to buy a Chromebook. These are pretty inexpensive laptops that run Chrome OS. I ordered one online at Best Buy, and arranged to pick it up in the store.

However, when we arrived to pick it up, it wasn’t ready. So we started browsing. That’s where the trouble started. They sell Apple gear.

To make a very long story short, between then and now, I’ve managed to replace most of our gear with Apple stuff. We traded our Android phones for iPhones. We replaced our Android tablets with iPads. And I ended up replacing my PC with an iMac. (my wife will still be using a Windows PC)

I was fortunate to be able to sell my old desktop PC for a reasonable price. So that helped. But my allowance will take awhile to recover from this.

So far, I’m enjoying being an Apple user again. I originally became a Mac user back in 2002, shortly after they introduced their new operating system based on FreeBSD (OS X). I think I sold my last Mac somewhere around 2009.

So Macs aren’t new to me. I had a bunch of old software licenses for stuff that I used to use back then. I’ve renewed and updated the licenses for a number of those things. Of course some of them are now defunct.

Before this, I was pretty deep into the whole Google ecosystem. All my stuff was on Google Drive. I have used Gmail for many years. But I figured if I was going to do the Apple thing, I would go the full route.

So I am now using the Apple iCloud stuff. It’s not perfect, but it seems to work pretty well. I have cloud storage, plus a lot of the Mac and iOS software use iCloud to sync data. I’m also using iCloud email. There was once a time where I had higher-end needs. But now for the most part, any reasonably capable service will fit my needs just fine.

And of course we’re using the Apple Music service for our tunes. When we switched our phones, we also dumped Verizon in favor of T-Mobile. One nice thing about T-Mobile is, they have free music streaming. So that’s what I end up listening to in my car most of the time.

Desense

I had a little problem with my ham radio setup at home. I figured I’d post about it here just for kicks. I have two “base” radios at home. One is a dual-receive Yaesu FT-7900R that I use to monitor local repeaters. My second rig is an Alinco DR-135 that is connected to my Allstar node. The antenna for my Yaesu is up in the attic above the garage. The antenna for the Alinco was in the garage below.

The Alinco is a 2-meter radio. I run it at 5 watts. When my Allstar node is connected to another node/hub, the Alinco transmits whenever there is activity on that node/hub. The output of the Alinco was essentially “desensing” my FT-7900. The symptom being that the FT-8900 suddenly became “hearing-impaired” whenever the Alinco was transmitting.

I typically monitor the Alinco radio from inside the house on my HT. And 5 watts is way more than I need for that. Unfortunately, regular mobile rigs don’t usually go lower than that.

I tried moving the Alinco node radio into my office in order to gain a little more distance between the two antennas. But even on low power the RF got into some of the electronics in the room which made that an unworkable solution.

After considering a number of other possibilities, I decided to take the antenna off the Alinco node radio and swap it with a dummy load. I tried this last night and it seems to work really well. I located the node right in my office and the RF no longer interferes with any electronics. And the dummy load allows enough RF to pass where I can talk though it from my HT with no problem.

Gear swapping

After concluding a couple of weeks ago that I wasn’t going to be able to do HF here at home, I sold all my HF gear on eBay. I sold my Yaesu FTdx1200, my Buddipole and my Comet antenna analyzer. I also sold my Signalink (since it’s intended use was on HF).

I got pretty good prices for what I was selling. I actually sold the FTdx1200 for only $45 less than what I’d originally paid a few months back. So I’m officially out of the HF business.

After selling all that gear I decided to make a few more changes. I have a node radio (a Yaesu FT-7900R) that I use with my Allstar node. I’ve been running it on 5 watts, but even 5 watts is overkill just for my local use. And it’s certainly a much nicer rig than what is required for a node radio.

So there’s this guy that obtains used commercial radios and resells them along with the necessary control cables for use as node radios for both Allstar and IRLP. You can’t just spin a dial and put these radios on the frequency you choose. These radios must be programmed via special software for the frequency and tone you wish to operate on. And that’s part of the service he provides.

So I ordered a GE MVS commercial radio for use as my node radio. And I requested he set the transmit power level to 500mw. It will be very sweet to have a commercial radio as my node radio that only transmits with 1/2 watt. Should be about perfect. I talk to my node radio with my HT on it’s lowest power setting which also happens to be 500mw.

I had been toying with putting my current node radio (the FT-7900R) in the car, but decided against it. Instead, I bought a second Yaesu FT-60R for mobile use and put my FT-7900R up for sale on eBay.

My wife and I switch cars fairly frequently. So it is really better that I don’t have something permanently mounted in a vehicle. What I will have is a mag-mount antenna in each vehicle. And I’ll move my FT-60R back and forth as I switch vehicles.

Node relocation

I’ve learned a couple of things about running an Allstar node. Nothing too earth-shaking.

1. The mobile radio hanging off the node computer can spend a LOT of time transmitting. Typically a non-commercial ham radio is not rated for this sort of duty-cycle. But I’m hoping that having the power set to the lowest setting (5w) will make a difference.
2. I’ve been experiencing a high number of dropped cellular calls. I don’t know for sure, but it seemed that most of the dropped calls happened while sitting 3ft from my node antenna. And these dropped calls probably happened while the node was transmitting. It is for this reason, as well as general RF safety that I decided to relocate my node to the garage (see pictures).
3. Technically I’m supposed to be monitoring the node at all times and have the ability to turn it off if need be. That is part of the definition of a “control operator”, which every ham station must have. However when someone is using my node, they are transmitting and my node is not. When my node is receiving RF it is sending VoIP out over the net, but it would be the repeater or node on the other end of the connection that would be transmitting. And for that I would not be responsible to the FCC. The repeater or node-owner on the other end would. My node would only be transmitting what gets received from the repeater or node that is on the other end of the VoIP connection.  Of course the repeater or node-owner on the other end may block me (and be justified in doing so) if someone on my end is abusing my node.

As part of the move out to the garage I set up a spare router that runs the Tomato open-source firmware to act as a wireless bridge. It connects to the wireless router in the house via WiFi signal and connects to this PC via ethernet. It’s not that different than having a wireless card in the PC, except that this PC runs an ancient version of CentOS Linux that probably has really iffy support for wireless cards. With the bridge it only needs to support the on-board ethernet.

How to setup an Allstar Link simplex node

Check out these three links:

Allstar getting started info: https://allstarlink.org/getstarted.html

URI: http://www.dmkeng.com/URI_Order_Page.htm

Cables: http://www.uricables.com/

The Allstar folks are the ones who offer the ACID Linux distribution which has all the software you need to run a node. Much of it is preconfigured. It’s essentially CentOS 5.11.

So, buy the URI and the right cable for your radio. Download ACID Linux and install it on an old PC. And hook up the radio. Then configure and adjust the audio tuning in the software.

Most all the configuration can be handled via the Allstar portal. You set the configuration there and and it actually pushes it onto your computer. You do need to setup port forwarding on your router for this to work.

If you wish to enable Echolink, you need to forward those ports as well. This software will do Echolink with very little extra effort. But you will want to change your callsign to have the -L suffix and switch it over to “sysop” mode.

Simplex node

Because of a recent VHF/UHF radio purchase, I ended up with a “spare” dual-band radio. And, I’ve been having some fun lately monitoring the WIN System on a local repeater (that is connected via IRLP). So I figured I might try my hand at setting up an IRLP simplex node. I’ve had some experience with IRLP in the past and have really enjoyed it.

However as I was looking into it, I started hearing about Allstar. That is an alternative to IRLP. It’s a little cheaper to get started with Allstar, and it offers full-duplex operation. And it uses standard open-source VoIP software to do it’s thing.

So here you see my main computer, and next to it is a $45 Goodwill special. It’s a Core 2 Duo with 1GB RAM and an 80GB HD. Pretty wimpy, but more than enough to run the special Allstar Linux CentOS distribution. This Linux distribution comes with all the stuff needed to run an Allstar node and does the setup for most of it.

So I’ve applied for and received my node number. I went ahead and finished the Linux installation last night and that’s all good.

The only things I had to buy (besides the computer) were the URI (USB Radio Interface) and the URI cable. The URI plugs into a USB port and the cable connects it to the radio.

Now patiently awaiting those last two pieces.

So in theory… once this is all complete… I should be able to sit on my couch with my HT and talk to my node radio in the back room which will control the node. I can connect to other nodes all over the world with a few DTMF commands. And the connection quality should be rock-solid and full-quieting.

Plus, I have a neighbor who is a ham. He should be able to use it as well.

Trial and hopefully not error

For most ham radio operators… having a decent working HF station is somewhat of a holy grail. First, let me define HF for those not familiar. The term HF stands for “high frequency”. This is the type of ham radio where you can talk around the world. Other types of ham radio (like VHF and UHF) are only suitable for local communications.

So most hams want to do HF, but it takes a lot more energy and effort. It also takes more dollars and higher license privileges. I’ve had the license privileges needed to do this for quite a few years. But I’ve only had an HF station very briefly. An HF antenna typically takes a lot of room. People who live in apartments or in houses that are on small lots face many challenges in setting up an antenna that will work. Also, many homeowners find themselves restricted from putting up antennas due to CC&R rules and such.

My wife and I recently bought a house and we live under such restrictions. The rule is basically, no antennas. However, there are a lot of “stealth” options available where you can put up an antenna (particularly a wire antenna) that people cannot see or will not recognize as an antenna. As I’ve recently become interested in operating HF, I’ve been thinking a lot about those options.

One possibility is putting up an antenna in one’s attic. Radio waves typically go right through wood and other building materials like sheetrock and roofing. However metal such as ducting or electrical wiring are problems. Other problems with antennas indoors or in the attic have to do with all the interference caused by normal household electronics. Not only will the electronics bother the radio reception, but the radio will likely bother the household electronics when it transmits as well. Then there is the reality that a misstep in the attic will mean a large hole in the ceiling and/or an injury. That’s the part that discourages me.

One can string wire antennas around their property. But a common example of a wire antenna would be 102 feet long. I have nowhere outside where I could possibly string a wire that long in a straight line. You can get creative and zig zag wires different directions or around corners but then you face the fact that it’s fairly likely that you’ll try many things that don’t work or don’t work very well. I know a lot of hams like this trial and error. But honestly, I just don’t want to dork around that much.

So I decided to go with the very well-known portable antenna called a Buddipole.

This will be 18 feet high. And while it’s not exactly “stealth”. It is not a fixed antenna. I can take it down in about one minute. And I would typically only have it up when it’s in use. So I think because it’s not mounted on the house or any fixed structure, I should be able to squeak by the restrictions. And it has the distinct advantage of being known as a very effective antenna (for it’s kind) where you basically follow the instructions, put it together, and it works! Gotta love it.

For my radio… I have long been wanting a Yaesu FT-857D. There was a $50 rebate on these that ended two days ago. I bought the radio online with the “will-call” shipping option on the last day of the rebate offer. I had been debating between that radio and the Yaesu FTDX1200. The FTDX1200 is far more radio. But it’s not as versatile (and certainly not as cheap). And it didn’t have a rebate.

However, the day after the rebate offer on the FT-857D expired I was on the store’s web site and guess what was on their front page? The FTDX1200… with a $200 rebate!

While it’s not typically going to be something I’ll take out of the house to operate at the park or whatever, it will be much nicer to use at home than the little FT-857D.

The reason for the title of this post… is because in spite of the fact that this is a “good” radio and a “good” antenna. There is no guarantee that it will work well here, or even be usable. There is only one way to know. It’s possible that it will totally suck. Here’s hoping it doesn’t.

More new gear

I’ve been playing with my new Yaesu FT-60R HT a bit. Works great at home. And works fine in the mobile. I have ordered a headset to use with it while I’m driving. But even without the headset I was able to use it while driving with the top down on the freeway today. Although it was a little hard to hear. However the audio is quite good.

My involvement in ham radio has dramatically increased since getting the new HT. Mainly as a result of trying harder. Rather than simply tossing out my call sign and hoping someone will come back to me (which they rarely did). I am now attempting to come back to others who come on the air wanting to talk. Really, for that to work I just need to be willing to talk to anyone. And honestly, that’s great practice for life in general.

As a result of my renewed interest and increase in activity, I decided to go ahead with my initial plan to replace my ICOM base (IC-208H) with the Yaesu equivalent shown below (the FT-7900R). I’ll be running it on low power (5 watts) using a 1/2 wave mag mount stuck to my metal desk. This is a setup that I already know works quite well for the local repeaters.

I figure I’ll use new FT-7900R for my base unit at home, and my HT for mobile use… with a mag mount and a headset. I’ve decided that I’m definitely a Yaesu fan.

One of the issues I’ve been wrestling with is the idea that an SMA connector on an HT is not designed robustly enough to withstand repeated and frequent swapping back and forth between antennas. So my thought was that I need to stick with either the normal HT whip, or a pigtail for connecting to an PL-259, but not normally switch between both. So that means if I default to using it for mobile/base use with a pigtail, then I generally won’t be using it as a portable.

While this is a little bit of a disappointment, considering how nicely the FT-60R works as an actual “handheld”. The idea of having a radio that is strictly for handheld use is not that feasible either. Because it would rarely get used. Although it’s hard to anticipate my usage habits. As I get more involved, my past habits are not necessarily useful for determining future usage.

I have thought of the idea of perhaps getting a second FT-60R. I already have all the accessories. But how doofy would it be to have a second radio just so I don’t have to swap antennas. I will continue to ponder this.

The eBay auction where I was selling my old ICOM IC-208H closed yesterday for $282. That should cover the new radio. I like the top-facing speaker. That means I might get away without having to use an external speaker on my desk.

Rock music… pride comes before a fall

I’ve recently been driving our convertible more than normal. I always drive it with the top down whenever I can. We’ve been pretty blessed this year with many sunny days.

As I am driving with the top down and the sun shining, I tend to crank the tunes. I often find that Christian music just doesn’t capture the mood. Although I can’t for sure tell you why. Except that the SiriusXM Christian station is way more pop than it is rock. And I’ve always been a rock fan. Pop often makes me cringe.

So I will often find a secular rock station and crank it to 11 while I’m cruising down the highway.

That’s all good right? Or is it? Here’s where I wrestle. As I observe my own behavior and the music I choose, I’ve noticed a few things.

First, let’s establish one thing. God hates pride. A lot of folks think that God is love and everything is good. Well God definitely hates certain things and pride is on the top of his list. Here are a few quotes out of Proverbs.

“These six things the Lord hates, yes, seven are an abomination to Him: A proud look, a lying tongue, hands that shed innocent blood, a heart that devises wicked plans, feet that are swift in running to evil, a false witness who speaks lies, and one who sows discord among brethren” (Proverbs 6:16-19).

“Every one that is proud in heart is an abomination to the LORD” (Proverbs 16:5)

There are many other quotes I could add, but that is a small sample. As I was listening to certain secular rock, I was thinking to myself… I don’t know anything at all in this world that exudes pride more than secular rock. I mean think about it! Much of it really boils down to artists thumbing their nose at God and authority in general. And according to the Bible, God really hates that. He doesn’t use the word “abomination” lightly.

Does all secular rock fit that stereotype? No. But I believe the great majority of it does. I think maybe it was AC/DC that I was listening to when I had the thought about pride. But there are any number of bands that fit that description.

The other thought I had was this… why do I listen to the music I do? Of course part of it is the enjoyment I get. I really love a wailing guitar. But there are people I know, maybe not very well, whose main knowledge and information they have about my personal life consists of the music they hear me listen to.

And maybe I listen to what I do in part, because I sub-consciously want to send a certain message. It’s sort of fun to listen to “cool” music and have people be a bit surprised that this 54 year old guy is rocking out.

Jesus tells us that His people will suffer persecution because they believe in Him. I wonder if He appreciates one of His children essentially identifying with the rebellion and pride of the world by way of what music they listen to. Should one of His children really want to gain the acceptance of the world in this manner?

When I have Christian music turned up loud in the convertible, do I turn it down at the stop light so those around me don’t hear? If there is a really good ZZ Top tune on… I might be way more tempted to leave it cranking at the light. Maybe?

This is my observation. That much of secular rock exudes pride. And when we listen to that, we are participants and are actually identifying with that mindset. And we are likely transmitting that to others around us.

Well, I don’t think that’s something that God feels very good about. Historically I’ve pretty much blown this off as a “gray area” that cannot necessarily be categorized as sin. But not caring about this is quite prideful in and of itself.

In psychology there is information about a phenomenon that is quite interesting. When we view movies or listen to music. Our brains play certain tricks on us to make us feel like we are participating. Can anyone identify with playing the air guitar? or invisible drums? Of course! And when you see a very moving film. Why do you think it has that effect on you? Because you feel part of the story!

So there you go. Maybe the choices we make about the “media” we consume are not as benign as we like to think.

Ham radio equipment fun

I haven’t been that into ham radio since moving out of Salem. I knew folks in Salem. The further away I move, the lower the percentage of people on the radio I actually know. In addition… my involvement/usage declined quite a bit after getting married. Funny how that happens when you actually have someone to talk to (as opposed to when you don’t).

A couple of months ago I sold one of my two mobile radios and my HT to help offset the cost of the new PC that I built. This left me with one mobile radio, which I was using at home as a base. Since I use this radio with an indoor antenna, I don’t go above low power (5 watts). But that’s no problem because I can hit all the local repeaters with that just fine.

The HT I sold was a Kenwood TH-F6A. Widely held (at one time) to be the best HT out there. It’s a tri-band radio that will transmit with a full 5 watts on 220. It has dual-receive and all sorts of nice things. I never liked it. The main reason was the lack of a physical squelch adjustment, and an inconveniently located volume control. To me, those two things totally deserve their own physical controls that are easy to manipulate.

After selling these two radios, it wasn’t too long before I was kinda longing for a Yaesu FT-60R HT. I’ve had one of those before and really liked it. And it has nicely-placed squelch and volume controls. It’s also very well-built.

So a couple of days ago I did it. I bought the FT-60R along with a number of accessories. I’ve always had spare batteries and quick-chargers for every HT that I’ve had. So I wanted to do that again. But this time instead of going with cheap knock-off accessories, I went with the name-brand Yaesu battery and quick-charger. Add to that a factory Yaesu speaker-mic, a Diamond after-market antenna, and an antenna pigtail/adapter so that I can use the HT with standard external antennas.

After this purchase I started thinking that, dang, I like Yaesu products! Maybe I should sell my ICOM IC-208H base rig and replace it with a Yaesu too! However I also started thinking that, dang, that new Yaesu HT was spendy. My poor allowance is going to be in the hole for awhile on that one.

That’s when I made the decision to sell my ICOM base rig and use the new Yaesu HT for both base and mobile. No replacement necessary. I already have two really good mag-mount antennas. One for use at home and one to use in the car.

One really nice aspect to using an HT and a mag-mount for mobile use is… no installation. Slap it on and go! No issue with where to get power. No issue with where to mount the antenna. Perfect! Of course I won’t be able to work weak repeaters with that mobile setup. But it seems to me that the benefits are totally worth that tradeoff.
