New Radio
Well, I finally broke down and bought a new rig this week. You may recall I was debating between a Yaesu 950, Kenwood TS-590, Elecraft K3, and Ten Tec Eagle. I ended up buying a Kenwood TS-590. What led to my decision, you ask?
The simplicity of the Ten Tec Eagle is nice and refreshing, but I just couldn’t bear spending over $1,800 for such a simple rig. It bugged me that the MARS mod wasn’t readily available. This is one of my idiosyncrasies; any rig that I have must be able to transmit on whatever bands its capable of transmitting on, and I abhor hardware limited by software. And for over a kilobuck, can’t Ten Tec spring for a second antenna connector?
Volumes have been written about the Elecraft K3, and any review below a 5 out of 5 gets dirty looks from the studio audience. Yes, it’s a great rig, and initially it looks like a great deal until you start adding on the add-ons you really need to operate this rig. Right off the bat it’s $2,100 for a 100 watt rig. If you’re like me you’ll want a CW filter, a tighter phone filter, perhaps one to listen to and operate AM, and the general coverage filter band pass unit, and you’re looking at another $580. Also, the chassis of the K3 is below what I would consider for a rig in this price class. It’s not badly designed, but it’s really time Elecraft puts the big boy pants on and makes a die cast chassis. I know someone will quip that the Yaesu 950 and Kenwood TS-590 receivers aren’t as good as the K3. You’re absolutely correct. Is that extra few dB of IMD performance or receiver sensitivity really worth an extra $500 – $1K?
I was torn between the Yaesu 950 and Kenwood TS-590. Two things tipped the scales in Kenwood’s favor. A read several reviews about the Yaesu’s multiple roofing filters being not that useful, however they made it a major part of the user interface on the front panel. The other mention was Yaesu’s menuing system. Having three Yaesu products currently I’m quite familiar with Yaesu’s menus, however I can’t say I really like them.
A few reviews of the Kenwood TS-590 indicated better performance on CW than the 950. Admittedly I wanted to give Kenwood another try after their HF “design drought” of eight years, my fond memories of Kenwood back in the 80s and 90s, and the 850 I have has given me lots of great service for 14 years. I was a bit nervous about the TS-590 having operated a TS-570 years ago at Field Day and being disappointed in the receiver, however Kenwood literature, which was quite extensive, indicated that the 590 was designed anew from the ground up.
The TS-590 so far hasn’t disappointed me. I was able to figure out nearly all of the functions in the first 15 minutes without cracking open the manual. Power, mic gain, and VOX settings are easily accessed with single keystrokes and don’t require menu navigation. The menu is accessed via a button aptly labeled MENU. The knobs have a quality feel to them and the front interface is consistent and well laid out. What don’t I like? Two items: the number keypad on the left side has the bands (1.8, 3.5, 7, 10, etc.) as the primary marking on the buttons and the number (1, 2, 3, 4…) are secondary, which gets confusing when doing direct frequency entry. The second item is the CW QSK. Much like my TS-850, it makes more relay noise than I would like, however it sounds good in the headphones.
The manual is very well laid out, and doesn’t have the Japanglish commonly found in older Kenwood manuals. The rig achieves a nice balance between simplicity and complexity, not being overly flashy and offering a straightforward and useful display. The free software controls every aspect of the rig, down to the AF and RF gain and power, and it’s a rather well designed and intuitive application. New firmware can be uploaded to the rig as it becomes available. I especially like the filter controls which are on one knob. In CW mode it acts in shift and width mode, and in phone it changes to lo cut / high cut, which makes a lot of sense.
Overall, I’m pleased with my decision, and hats off to Kenwood for a nice little rig. Sorry Yaesu, but let me know when you have an FT-817 replacement out and we’ll talk. :-)
Thoughts While Lawnmowing
“I wonder if that new antenna radial I dropped last fall settled into the grass enough by now?”
THWAAAAAAAAAAAAACK!
“No.”
FCC Relinquishes Amateur Radio Licensing
In a shocking and unexpected move, the FCC today transferred all amateur radio licensing responsibility to QRZ.com, releasing Report and Order 2013-699. Outgoing Chairman Julius Genchowski read a statement noting that the decision was due to a combination automatic budget cuts from budget sequestration and an acknowledgement of reality. Other commissioners released similar written statements. The Report and Order stated, ”Our enforcement bureau received an inquiry from a radio amateur who was banned from QRZ.com (“QRZ”), an amateur radio portal and a popular callsign database. After his callsign listing was removed from the QRZ database, amateurs frequently questioned on the air whether he was really licensed. On a few occasions he was actually referred to as a ‘bootlegger’ by other radio amateurs, a derogatory term for an unlicensed individual operating illegally. Our research indicates that few licensees actually use the FCC ULS [the official online licensing database] for amateur radio license queries. In this ruling we have identified an opportunity to shed the responsibility of licensing and reduce administrative costs, and are therefore transferring administration of amateur radio licensing to a private entity.”
FCC Chairman Genchowski Makes Announcement to Stunned Audience
At press time ARRL had not released a written statement due to a backlog in the ARRL email server, still processing emails from a month ago. However, in a conference call this afternoon it was announced that ARRL was petitioning the FCC to withdraw the R&O until it could present its solution for privatizing amateur radio licensing, a solution employing 65,535 bit encryption technology which would be ready sometime in 2019.
QRZ praised the FCC change and announced that for a limited time free Extra class upgrades will be included with an XML subscription or purchase of Ham Radio Deluxe. QRZ forums were abuzz, with both support for and opposition against the change. One super moderator stated that QRZ super moderators will have enforcement privileges, with the ability to revoke licenses for bad behavior both online and on the air, later taunting to users to step out of line and “feel his wrath.”
The FCC announcement is the most notable change in US amateur radio licensing since the controversial and still-debated Incentive Licensing program, and will go into effect upon publication of the Report and Order in the Federal Register.
Misconduct and Consequences
Larry, W2LJ, recently wrote about a topic that all of us can identify with, the LID in a DX station pileup who ignores protocol and has no sense of manners. They ignore DX requests for specific stations to respond and just blast the frequency, often with high power, until they get their contact. The problem has existed for decades and is nothing new. It’s one reason why I get turned off by DXing (despite dreaming of going on a high profile DXpedition someday), and it’s especially frustrating for a QRPer where timing and skill are much more important due to the power disadvantage. Conversely, RF power often makes up for a lack of skill or manners, and the DX pileup LID makes a nuisance of himself to the point where the DX station can’t ignore him, and rewards him with a QSO.
The problem has been going on too long. The reason it continues to exist is much like why we have email spam after nearly 20 years of the “mainstream” Internet. There’s no cost associated it, and the bad behavior is rewarded. The DX Code of Conduct is a great model for people to follow, but unfortunately it’s only the honest and polite people who follow it. There must be consequences for bad behavior.
First off, DX stations need to stop rewarding these LIDs with contacts. They need to call them out and let them know they’re not getting a contact during the DXpedition. Perhaps we could create a specific Q signal that says “you’re blacklisted” to keep it short and sweet and avoid long on the air explanations. Or they can work the station and not QSL the contact and let the station know through some means they got a non-QSL for their bad behavior.
Second, DX organizations and organizations like ARRL, CQ, and perhaps RSGB need to maintain a “three strikes” policy. If they receive evidence, such as recordings, of bad on the air behavior three times within a given period, the offender has awards stripped and they’re identified on a blacklist that can be accessed by high profile DXpeditions. The minutia of appeals and reinstatement and the level of public notification can be debated, but I think the basic idea is sound and something that needs to be done.
This all may sound harsh, but in order to change bad behavior there needs to be consequences. All too often in amateur radio we don’t call out bad behavior and it affects the enjoyment of the hobby for the rest of us. It’s time for the organizations who have the power to enforce consequences, to take action, rather than continue to provide rewards.
Don’t Fear the Penguin
It’s day four of my hopefully last Windows-to-Linux migration, and so far so good. I have my HRD log imported into CQRLog and it’s talking to both my Arduino Keyer and Yaesu FT-897. The Keyer is happily sending CW and CQLog is reading the rig frequency. The rig control function is very simple and utilitarian compared to HRD’s, but it works. What I cannot get working is controlling the Kenwood TS-850. This appears to be a problem with Hamlib, which CQRLog uses via rigctld.
I found that Linux re-enumerates USB /dev/ devices if you unplug one. For example, I had my Arduino Keyer at /dev/ttyUSB0, my TS-850 interface at /dev/ttyUSB1, and my FT-897 interface at /dev/ttyUSB2. Upon unplugging the Arduino Keyer and TS-850 interface, the FT-897 became /dev/ttyUSB0, and with nary a mention in syslog. I find this behavior strange. But I’m really pleased Linux handles USB device insertions and ejections so well. Back in the day to do stuff like this you’d have to edit some text file, recompile your kernel, and walk uphill in snow both ways.
To run N1MM I installed Virtualbox and within that installed a very bare bones Windows XP installation. This enables me to run Windows XP as a virtual machine within Linux, without rebooting. N1MM installed and ran without a hitch in the virtual machine. I was reminded N1MM likes to install in C: root, like it’s 1994 on Windows 3.1. But I digress. Attaching host USB devices to virtual machines in Virtualbox is a piece of cake and I had N1MM talking with the 850. So I’ve got my contesting needs covered.
It occurred to me that it wouldn’t take much to get CQRlog to do basic contest logging. It already has cw interface keying and function key definitions and macros. All it really needs is serial number generation with corresponding function key macros, previous QSO report lookup, and perhaps a little more field customization. This would cover the basics. One can handle scoring outside the program, but a band map with the DX cluster integrated would be the next feature on the list. I may just look at the source code and see if I can make sense of it and maybe play around with some customizations. I sense another project I’m going to get sucked into.
So far I haven’t had to go back to my native Windows installation for anything, other than to steal more disk partition space. Maybe I cheated a little by installing an instance of Windows XP on Virtualbox, but hey, whatever gets the job done!
(Update: I just found the CQRLog band map window and it is integrated with the DX cluster!)
Migrating to Linux (Again)
I’m no stranger to Linux. I’ve run numerous distributions since about 1995, even venturing into BSD territory, running FreeBSD and some other Berkeley variants. I’ve also used Linux quite a bit in my professional life for servers. However, I’ve never made the jump to using it as my primary desktop operating system at home; it’s always been a novelty to play with and never a desktop workhorse that I would use to actually get things done.
Linux Mint is a Linux distribution that has become more popular recently. It’s based on the venerable Ubuntu distribution and appears to be taking some market share from Ubuntu. Ubuntu in my opinion went off the tracks with its migration to the Unity desktop. For the first time recently I hit a brick wall trying to install the latest Ubuntu within a virtual machine. While Ubuntu was quite polished and arguably had the best usability in the Linux world, I still felt that I was often fighting the operating system to make it work.
Linux Mint seems to have taken care of those issues. Last night I made the plunge and partitioned off some space on my hard disk and installed it so I could dual boot between Windows and Linux. The installation went extremely well and within two hours I was able to browse the web, play videos and hear sound, send email, work on Kicad schematics, compile Arduino code, open Excel and Word docs, do my banking with the same program I used on Windows, and I had amateur radio logging and digital programs installed. The only speed bump was getting my wireless working. I was able to fix that in five minutes after Googling and finding one command line to run. On previous distributions, items like this would take hours to resolve and there would be several of them to deal with. For the first time I feel I have something equivalent to what I had on Windows, and it doesn’t look goofy and didn’t require days of tweaking with arcane command line syntax to make it acceptable. The browser actually renders things like they look on Windows. You install a program and it actually appears in the menu. Quite simply, Linux Mint isn’t a compromise like previous desktop installations.
I’ve often complained about the state of amateur radio open source software. I stand by my previous statements as I think we still don’t have a suite of amateur radio open source software that compares with offerings in Windows, mainly in the areas of logging and contest programs. However, CQRLog has evolved quite a bit and I’ve decided to take a more minimalist approach and see if I can make it work. I still think Ham Radio Deluxe is the gold standard, but lately I’ve become annoyed with its bloat and the commercialization and marketing of it.
I’m still keeping my Windows partition, mainly to run one particular contest program and store my documents (which I access from Linux), but I may eventually run Virtual Box on Linux and have a small Windows installation virtualized to run the contest program rather than booting back into Linux.
Will this be the time I finally run my shack on Linux? I hope.
I Was A Radio Pirate
Back when I was a young radio artisan I would eagerly await my monthly copy of Popular Communications to arrive. My favorite column was Pirates Den which covered the latest happenings in pirate radio such as new stations, signal reports, programming, and stations shutting down, either voluntarily or involuntarily at the hands of FCC enforcement. The often grainy black and white images of stations with masked DJs seemed like a glamorous and exciting thing at the time. Back then you couldn’t just setup your own audio stream on the Internet and broadcast to the world. As a pirate you could say whatever you wanted, play whatever music you liked, and all the while stick it to the “man”, the brutal, authoritarian FCC. Fines at the time were only a few hundred dollars, paltry by today’s standards.
There were basically two pirate “worlds”, local broadcast and shortwave. Shortwave stations would operate just above the 40m amateur band. In later years the pirate band moved to below 40m. Other frequencies on other international shortwave bands were used, but the neighborhood around 40m seemed to have the most action. Local broadcast would be done mainly on FM radio. I actually can’t recall a report of an AM broadcast pirate, but I assume there were a few out there. But considering the effort and equipment one had to put into an AM broadcast band operation, those people with the skills and inclination to go to that effort probably did shortwave pirating.
I had dreams of becoming a real DJ and perhaps owning my own commercial FM station one day, but luckily I realized that the broadcast industry had a rather low pay to frustration ratio and steered clear of it professionally. In college I finally got the gumption to attempt to become a radio pirate. I didn’t have two nickels to rub together at the time, so any purchase was a big decision. I sent away for a mail order FM radio kit. It was mono, not stereo, but it boasted a phase-locked loop (PLL) and a clean 1 watt output. Paradoxically, being a licensed radio amateur I wanted a very clean and professional pirate FM signal. I assembled the kit, however, much to my dismay after weeks of trying to get the PLL to lock up, I gave up and tossed the unit in the closet.
Two years later I was working professionally in the RF world, working on TV transmitters around the globe. I learned a lot in this new world. Being a field engineer in the middle of nowhere like South America or the Middle East with a minimal assortment of parts and people staring over your shoulder expecting you to fix their only transmitter in the village makes you learn quickly and think on your feet. This is something they don’t teach in college or outline in an ARRL Handbook. It was a rough job that no one wanted but I came into the company bright eyed and bushy-tailed and commanded more pay than some of the travel-adverse bench techs with years of experience under their belts.
One day I got bit by the pirate bug again and snuck a spectrum analyzer out of work to my bachelor pad. I got the bright idea of bypassing the PLL and just driving the voltage controlled oscillator with a multi-turn pot, also borrowed from work. The unit would drift but after a few hours warmup it didn’t require much adjustment to stay on frequency. Later I found an old low band VHF TV amplifier rated for 25 watts at work. It was a design that apparently was a bit unstable, but we had several of them lying around at work, destined for the dumpster. I took one home and tweaked it up and found I could get 40 watts cleanly out of the unit. Now I was in business.
I assembled a station, acquiring an audio mixing board and other components. I built a ground plane antenna and got four 5′ Radio Shack masts to elevate it. My third floor apartment was in a great location, in the middle of a nine mile long heavily populated valley in northeastern PA.
A college friend would come over Friday night and stay over for a pirate broadcast weekend. We would do a few two hour shows and identify as WMRX, “the station jamming the nation.” Though a bit kooky now, it sounded pretty cool back then. We spun mostly records and a few CDs, and we augmented our programming with supermixes or song medleys recorded from a commercial station in Philadelphia. We even did a ten minute fake news report with some comedy thrown in. For a phone line we announced the phone number of the pay telephone across the street. One of us would stand at the phone while the other announced the number on the air. We never did have anyone call in.
One show ended early when my co-host got intoxicated and fell over. Another show had to be cut short when a guest DJ announced my name over the air. After each broadcast we disassembled everything, including the antenna and mast and hid it, naively assuming this would minimize our chances of getting caught. Eventually work and life got too busy and complicated and the pirate operation stopped. Every few years I fired up the transmitter, put a CD on, and just drove around to hear the signal and admire the coverage. Although it wasn’t stereo and it didn’t fill every nook and cranny in the valley with RF, it was my signal, my station, built with my own hands, and to me it sounded wonderful.
Today FM pirate broadcasting lives on, as regular reports of FCC enforcement would attest with fines in the neighborhood of $10K to $20K. It’s hard to tell if shortwave pirating is still alive. It’s certainly not at the level it was in the 80s. I get the feeling anyone with a desire to get a message out rather than just spin records or taunt the FCC has moved to Internet broadcasting or perhaps uses a blog to get their message out, though it lacks the mystique and excitement that pirate radio once had.
