WordPress Security

WordPressMy site has been down for a few days due to a “security problem” that I encountered. it seems that some malware showed up on the server and my host disabled the site. It took a bit of ftp’ing to get the offending files removed but we are back on the air.

I can’t say for certain how the bad guys got into the site but it would appear they were specifically targeting sites using WordPress. I was already running a security plugin for WordPress but since the attack I’ve tightened up the parameters considerably. If I inadvertently locked you out, my apologies.

It is interested to watch how many attacks are reported by the security plugin, mostly from locations outside of the US. If you are using WordPress and don’t have a security plugin installed, I highly recommend installing one and locking things down tight.

ARRL Field Day: Season To Taste

2015 Field Day Logo Red Design 1I’ve written before about the flexibility of Field Day and the need to season to taste to make it your own. I have always thought that one of the great things about Field Day is that it can be tuned to whatever interests you or your club. It can be a serious radio contest (well, almost); it can be an emcomm drill. It can be a radio campout; it can be a foodfest, it can be a beer-drinking party. Insert your idea here.

This year, our local club, the Tri-Lakes Monument Radio Association is going to try a new approach that we call Tech Field Day. We previously have held a one-day educational event that we call Tech Day, that featured a series of presentations and hands-on demonstrations. The main theme of Tech Day was to help the Technician level hams gain more knowledge and help them move on up to General class operating.

We are taking the basic idea of Tech Day and combining with a shortened one-day version of Field Day. So on Saturday June 27th, we’ll offer a series of educational presentations along with some classic Field Day radio operating. The operating emphasis will be on giving newer hams a chance to get on the air, probably on both HF and VHF. (Our plans are still coming together.) We will also promote the theme of emergency communications, operating off a emergency power source, etc.

There are a number of things that we are intentionally leaving out. We won’t operate the entire 24 hour period…in fact, we’ll probably just be on the air Saturday afternoon. We won’t worry about making a lot of contacts or running up the score. Our stations will be relatively simple (no towers, no amplifiers).

So that’s our idea of a fun Field Day. What are you planning to do?

2015 SOTA VHF Activity Days

Bob summitOn the topic of operating events for Summits On The Air (SOTA) activations, Guy N7UN suggested focusing on six major events for 2015. Most of these are VHF-oriented but HF activity can also occur on these days.

IMG_1836Of course, any day is a good day for SOTA activity. I also think six weekends are a great way to focus our operating activity and create S2S (summit to summit) radio contacts. The August 1-2 weekend looks to be the alignment of the planets with four events happening on that weekend. Early August usually offers excellent conditions for hiking the highest peaks in Colorado, so come on out and play.

For more info on VHF SOTA, see How To Do a VHF SOTA Activation.

Get off the couch, put on your hiking boots, grab your backpack, grab your radio but most important: get on the air!

What’s All the Fuss About K1N?

If you have been paying any attention to the world of ham radio DX, you have heard about the DXpedition to Navassa Island. According to Wikipedia, Navassa Island is a unorganized, unincorporated territory of the United States. Haiti (just 40 miles to the east) also claims ownership of the island but it appears that the US currently has control. The island is designated as the Navassa National Wildlife Refuge by the US Fish and Wildlife Service and access to the island is severely limited. (There is some interesting reading about the various territories of the US on Wikipedia.)

Navassa Island mapFor the purposes of DXCC, Navassa Island is considered a separate country (I mean entity), one that is very difficult to work because no one lives there. Actually, its worse than that because hardly anyone is even allowed to set foot on the island, let alone install a ham station. This means that Navassa is near the top of the list of the most wanted DXCC entities.

An enterprising and persistent group of radio hams managed to get permission to visit the island and put it on the air. The logistical challenge is large, including the use of ships and helicopters to get all of the people, radio gear and supplies on and off the island. As you can imagine this gets quite expensive.

This is where I have to chuckle at the silliness of the situation. Imagine explaining this to someone that drops in from another planet. We have this hobby that involves communicating long distances via electromagnetic waves. One of the pursuits in this hobby is counting up how many countries you have contacted. Well, they aren’t all true independent countries, so we have to keep a special list to keep track of which ones are considered countries. Now, we have this one island that is on the list but we also have this rule that no one is allowed to live on this island. This causes a group of people to assemble a major expedition, costing a great deal of time and treasure, with the sole purpose of enabling electromagnetic communication from the island.

At this point, I should mention I am a slacker DXer. Many years ago, I did take the time to get >100 countries confirmed so that I could claim DXCC but I don’t spend much effort trying to chase new countries.  When I heard about the Navassa DXpedition, it did peak my interest because I knew it was such a rare opportunity. Who knows when and if I would get another shot at working this country? I also knew the getting enough RF from my station to Navassa would not be very difficult. It is only 2300 miles from Colorado, a slam dunk on 20m, even with my modest 100W to a dipole antenna. Except that there would be 20,000 other hams called at the same time, creating a huge pileup. Which is why I don’t get into chasing rare DX. While I love the challenge of bouncing my signal off the ionosphere to reach distant locations, I don’t groove on the pile up that normally ensues. That quickly turns into a contest of who has the biggest signal (size does matter) and who is most adapt at getting the attention of the DX station.

About the time that K1N started operating from the island, I was out of town on business. I began to think that working Navassa was not for me. However, I did manage to find some operating time on Feb 14, which turned out to be the last full day of K1N operation. After just a couple of calls, I got through the pileup and worked them on 20m SSB. (I’d like to think that it was superior operating technique but it was probably just dumb luck.)

Thanks to the team that put Navassa Island on the air. (Yes, I did send in a small donation to help the cause.) From what I experienced, this DXpedition was very efficient and well run. Take a look at the interview with one of the participants, Glenn W0GJ,  who had some interesting comments about the experience.

2014 World Radiosport Team Championship

From the World Radiosport Team Championship (WRTC) website:

The World Radiosport Team Championship (WRTC) is a competition between two-person teams of amateur radio operators testing their skills to make contacts with other Amateur Radio operators around the world over a 24 hour period. All teams use identical antennas from the same geographic region, eliminating all variables except operating ability.

WRTC2014 included 59 competing teams from 29 qualifying regions around the world. Competitors represented 38 different countries.

This is a unique contest in that the stations used are roughly identical so that operator skill is the main variable. I love watching these guys work the radios, especially the CW ops. Even if you are not a contester, take a look at this excellent video and enjoy radio hams having fun messing around with radios.

2013 Ford F-150 Ham Radio Installation

After acquiring a Ford F-150 truck last year, I’ve been working on getting a ham radio installed in it. At times, I have loaded up my vehicle with multiple radios covering HF through 70 cm but lately I am content with just having a reasonable dualband 2m/70 cm FM rig in the mobile. Actually, I used a Yaesu FT-8900 that does FM on 10m, 6m, 2m and 70 cm but just set it up for the two bands.

Figure 1 IMG_2206

One of the most critical questions for a mobile installation is what kind of antenna to install and where to put it. In the end, the antenna is going to be the main determinant of mobile performance. Ideally, I’d like to have the antenna on the roof of the cab but the truck will not fit in my garage in that configuration. Another option I considered was mounting a longer dualband antenna using one of the stake pocket mounts from Breedlove. I prefer NMO mounts for VHF/UHF antennas and the stake pocket looked like a good way to go. However, a little measuring revealed that a 1/2-wave or 5/8-wave 2m antenna on the stack pocket was not going to clear my garage door. So it seemed that I was limited to a shorter antenna. I may still use the stake pocket mount for an additional antenna for road trips or to add 6m and 10m antennas.

Figure 2 IMG_2036

At this point, the F-150 bracket offered by The Antenna Farm looked like a good option. They have a number of these brackets made specifically for various vehicles, so check them out. This made the antenna installation quite simple. <click on any of the photos for a larger view>

 

Figure 3 IMG_2041

The antenna is an NMO-mount dualband that I had laying around the hamshack. I don’t recall the exact model number but these are very common, about 19-inch long for 1/4-wave operation on 2m and a small loading coil to make it work on the 70cm band.

 

 

Figure 4 IMG_2163

The F-150 has several precut holes for passing wires through the firewall. I used one that is on the passenger side just  below a large module, as shown in the photo. It took a stiff wire and some force to punch my way through the rubber plug and into the cab compartment.

I don’t have a photo of the battery connection but I connected the positive lead right onto the battery terminal while the negative lead was attached to the truck chassis near the battery. You may have been told to always connect directly to the battery terminals but that advice no longer applies to some newer cars because there is a current monitoring device in the negative battery lead. To avoid confusing the vehicle battery monitoring system, the negative connection to your transceiver needs to be on the chassis side of the current monitor. Alan K0BG explains this issue on his web site. Actually, Alan has a wealth of information on mobile installations on his web site: www.k0bg.com. Oh, of course, I used inline fuses on both the positive and negative power cables.

Figure 5 IMG_2166

I mounted the FT-8900 transceiver on the floor under the back seat. To route the power cables and antenna coax, I pulled up the flat plastic trim piece that runs along the floor at the passenger door. I started from the front and did some careful prying (and praying) to remove the trim without breaking it. This exposes a trough with a factory wiring harness in it but there’s room for more. A few other plastic trim pieces were removed to get access to the wires coming through the firewall. All in all, this was not that difficult. (Yea, Ford!)

Figure 6 IMG_2197

The photo to the left shows the FT-8900 radio installed under the passenger side rear seat. I drilled holes through the floor and mounted the radio with hefty sheet metal screws. The screws go right through the metal floor and and can be seen from under the truck. (Check that out before drilling!) Because the radio body is under the rear seat, I am using a small external speaker mounted near the drivers seat.

Figure 7 IMG_2200

The radio control head is mounted inside a little door/shelf that normally pops open to reveal the USB port for plugging in a smartphone. (Note that Ford has multiple seat / dashboard configurations.)

 

Figure 8 IMG_2201The FT-8900 control head just fits inside this little shelf, even when the door is closed (see photo). The microphone does have to be removed to close the door. I mounted a microphone hanger with a couple of sheet metal screws, as shown in the photo. I don’t like the crappy little hanger that usually comes with a ham transceiver so I bought some higher quality hangers on Amazon.

Overall, I am pleased with the radio install. The antenna location is clearly a compromise and I notice the performance is not as good as my previous vehicle (which was a small SUV with an NMO mount antenna in the middle of the roof.) But the antenna is “low profile” and sufficient for “around town” mobile operating. I am getting a little noise on the 2m band which needs some investigation. The 70cm band is very clean and is the band I use the most.

Dorking With VHF Contest Rules

300px-International_amateur_radio_symbol.svgOne continuing discussion in the VHF community is how to promote more activity, especially during the major VHF contests. One central theme that always emerges is how to modify the VHF contest rules to make them better, to make them fairer and to encourage new contesters. (Let me say up front that there is room for improvement in the contest rules but I don’t think rule changes alone will change contest participation significantly.)

In 2013, the ARRL contests added the Three-Band Single Operator and Single Operator FM Only entry categories. In January 2015, the ARRL added three more categories: Single Operator Unlimited High Power, Single Operator Unlimited Low Power, and Single Operator Unlimited Portable. These “unlimited” categories allow “passive use of spotting assistance” which roughly means these operators can monitor the various DX spotting networks but not spot themselves. The CQ Worldwide VHF Contest already allows passive assistance for all participants and self-spotting for digital EME and meteor scatter contacts. See the CQ WW VHF rules.

In January, the ARRL announced additional changes:

The Board … adopted amendments to the General Rules for ARRL Contests Above 50 MHz to encourage greater participation and band utilization. The changes become effective with the 2015 June ARRL VHF Contest. The revisions stemmed from recommendations offered by the Board’s Programs and Services Committee’s ad-hoc VHF and Above Revitalization subcommittee, composed of active VHF/UHF contesters, and they received strong support from the VHF/UHF community.

The subcommittee was charged with developing recommendations to increase the level and breadth of ARRL VHF and above contest participation and encourage operation on lesser-used bands. As a start to the process, the Board approved three changes that will permit assistance for all operator categories, with no effect on entry category; permit self-spotting for all operator categories, and allow single operators to transmit on more than one band at a time.

The changes will permit assistance in arranging contacts, but not in conducting contacts. They will, for example, allow a station to announce its location in a chat room, on a repeater, or even via e-mail.

The self-spotting/assistance issue is a hotly debated issue among VHFers, with two main schools of thought:

1) Contacts should be made completely independent of non-amateur assistance. Sometimes passive spotting assistance is allowed, but some folks want to eliminate that practice as well.

2) Contacts can be made with non-amateur assistance (spotting networks, chat rooms, etc.) as long as a complete radio contact occurs over the ham bands. This follows the common practice of internet spotting for EME and meteor scatter. Also, some rover stations have requested the ability to spot themselves when they enter a new grid.

There are a number of shades of gray positions between these two points of view (see the CQ WW VHF rules, for example), but I won’t try to explain them here. In general, I support the move to loosening up the restrictions on assistance (#2). Without good 6m propagation, VHF contests tend to be “QSO poor” and expanded use of spotting will allow for additional contacts. The potential risk is that we’ll get sloppy with what constitutes a legitimate contact. Once I know the exact frequency and call sign of the other station, it will be easier to “hear” the other station even when the path is not there. Of course, we already have this situation when we complete a QSO on one band and QSY to another band to work the same station. We know the frequency and call sign (and the grid)…did we really hear the other guy or just think we did? In the end, it all comes down to the integrity of the radio hams involved in the contact.

Those are my thoughts. What do you think?
