Deal Alert: Tactical pack sale at Spec.-Ops. Brand

The Spec.-Ops. Brand THE Tactical Pack UAP

SWLing Post readers know I’m a certified pack geek. Well, I just received an email from one of my favorite tactical backpack and gear suppliers: Spec.-Ops. Brand. They’re having an unheard of 70% off sale on some of their overstocked tactical packs.

 

I’ve mentioned Spec.-Ops. in a number of previous posts as I own a lot of their gear including the T.H.E. Pack, Pack Rat, Triple S, DPO, Op Order Pouch, and All Purpose Bag.

If you’re into camping, preparedness, or just like backpacks, I highly recommend Spec.-Ops. gear. Everything is made in Texas and carries a lifetime warranty. When I bought my ($189) T.H.E. Pack Tactical, ACU on sale I got a great deal at $110–now they have this same pack for $56!! Yep–I’m likely going to buy another at this price.

Portable antennas: a review of the Par Electronics EF-SWL

Last August and part of September, I traveled through the US with the CommRadio CR-1 and a couple of portable antennas: the Par Electronics EF-SWL and  NASA PA-30. I had the opportunity to try both in the field, and took notes as I used them. Following is a short review of the Par Electronics EF-SWL.

Par Electronics EF-SWL 

At the Dayton Hamvention last year, I had the pleasure of speaking with representatives of the North Carolina-based LNR Precision Inc. LNR is a mom-and-pop company with a focus on providing antennas, keys, and transceivers for the ham radio and shortwave listener markets.  Indeed I have several SWL friends who use on a daily basis an antenna this company manufactures and retails: the Par Electronics EF-SWL. LNR asked if I would consider reviewing their antenna, and since I was planning a road trip with radios in tow–the perfect opportunity to test such an antenna–I agreed.

The Par Electronics EF-SWL is an end-fed shortwave antenna designed for 1-30 MHz reception. It’s a receive only-antenna–perfect for the SWL. The radiator is 45 feet of #14 black polyethylene coated Flex-Weave wire. When I first used the EF-SWL, I noted the quality of its construction: no doubt it can withstand many deployments in all weather conditions–and it’s manufactured here in the US.

With a 45′ radiator, the EF-SWL needs a little space, but offers more gain than the other portable antenna I packed, the NASA PA-30 (look for its review in the near future). I put the EF-SWL to use in New Mexico where several large trees were readily available. I hooked the EF-SWL up to the CommRadio CR-1 and simply hung the end of the radiator as high as I could in a nearby tree. Though not a picture-perfect installation, it nonetheless certainly did the trick! I didn’t bother with a ground connection as I wasn’t in an area with much radio noise (RFI).

In the past, when setting up portable ham radio and shortwave listening, I’ve typically built my own antenna either for the specific meter band I hoped to use, or brought along a portable antenna tuner. It was quite nice having an antenna designed to be resonant on the broadcast bands.

Par-EF-SWL

Though I didn’t do this, I did noticed that the EF-SWL’s radiator is attached via a stainless stud–Par Electronics did this so you can remove the radiator and replace it with a different wire length. With the stock 45′ radiator, I still find the EF-SWL quite portable, especially when compared with most of the portable amateur radio antennas I use, which tend to take a dipole or delta loop configuration.

After returning from my trip, I decided to hook up the EF-SWL at my home base for longer-term evaluation. These past months I’ve had it on the air as an auxiliary antenna, and I’ve been impressed with its performance. In truth, it’s not in an optimal location hanging off the corner of my house, but I think this may actually represent with some accuracy the installation most SWLs will likewise be able to provide–in other words, placement that must factor in antenna restrictions or limited space. Of course, for any permanent installation, you will need to ground the EF-SWL for lower noise reception.

And yet, even in these suboptimal conditions, the antenna performs remarkably well.

As with any exterior antenna, of course, take precautions against lightening if you live in an area with thunder storms. If nothing else, at least disconnect the antenna when not in use.

Moving forward, I will plan to relocate the EF-SWL to a more ideal permanent location and most likely purchase another to keep in my antenna bag. I hope to use this antenna in a DXpedition I’ve planned later this year.

The EF-SWL retails for $75 US directly from LNR Pecision or $72 US from Universal Radio.

Note that LNR also sells a number of QRP field-portable transceivers: the LD-5, FX-4a and Mountain TopperClick here for more details.

Traveling light, SWLing right: the best shortwave radios for travel

This article originally appeared in the March 2014 issue of The Spectrum Monitor Magazine.


SWL Travel Gear - Grundig G6

With spring around the corner, my thoughts drift toward the outdoors…and especially, toward travel. Those who know me know that I love travelling, anywhere and everywhere–and that I prefer to travel light, with only one bag. In fact, I can easily live for two weeks out of a convertible shoulderbag/backpack (the Timbuk2 Wingman) that’s so compact, I can fit it under the the seat of even the smallest, most restrictive aircraft. I never have to check luggage unless the nature of my travel requires extra supplies (I run Ears To Our World, a non-profit that donates radios and other technologies to powerless regions in the developing world).

My Timbuk2 Small Wingman is very compact, yet holds everything I need--including radio gear--for two weeks (or more!) of travel.

My Timbuk2 Small Wingman is very compact, yet holds everything I need for two weeks (or more!) of travel.

So, why not pack everything you could possibly ever want on a journey?  While this remains an option, travelling light has many advantages over the take-it-all traveler’s method. First, it gives one incredible freedom, especially when travelling by air or train.  I never have to worry about being among the first to be seated in an aircraft, nor do I worry about my luggage not making a connection when I do.  Second, it’s kinder on the back and shoulders, and easier to maneuver wherever I go–no wheels required–whether in a busy first-world airport or bustling third-world street market.  Third, I always have my most important gear right there with me.  And finally (I must admit) I find light travel to be fun, an entertaining challenge; the looks on friends’ faces when they meet me at the airport to “help” with my luggage is, frankly, priceless.  Seeing me hop off a flight with my small shoulder bag, friends ask in bewilderment, “Where’s your stuff?” It’s music to my ears.

You would think that having such self-imposed restrictions on travel–carrying a small, light bag–would make it nearly impossible to travel with radio. On the contrary!  Radio is requisite, in my book–er, bag.  I carry a surprising amount of gear in my small bag:  once at an airport security checkpoint, an inspector commented, “It’s like you have the contents of a Radio Shack in here–!” But more significantly, each piece–and radio–is carefully selected to give me the best performance, durability, versatility, and reliability.

So what do I look for in a travel radio? Let’s take a closer look.

SWL Travel Gear - full selection

Travel Radio Features

While the CountyComm GP5DSP only has average performance for its price class, it has three different ways of auto tuning stations quickly, an alarm function and the display will even indicate the current temperature. Its unique vertical, thin body might be easier to pack at times, depending on your travel gear.

The CountyComm GP5DSP has three different ways of auto tuning stations quickly, an alarm function and the display will even indicate the current temperature. Its unique vertical, thin body might be easier to pack at times, depending on your travel gear.

In a travel shortwave radio, I search for features I wouldn’t necessarily pick for home use, where I’m mainly concerned with raw performance. I don’t want to carry an expensive receiver while traveling, either: $100.00 US is usually my maximum. This way, if I accidently break the radio (or my gear gets stolen), I won’t feel like I’m out very much money.  I also prioritize features that benefit a traveler, of course; here are some that I look for:

  • Small size: Naturally, it’s sensible to look for a travel radio that’s small for its receiver class for ease in packing.
  • Overall sturdy chassis: Any travel radio should have a sturdy body case that can withstand the rigors of travel.
  • Built-in Alarm/Sleep Timer functions: While my iPhone works as an alarm, I hate to miss an early flight or connection, so it’s extra security when I can set a back-up alarm.
  • Powered by AA batteries: While the newer lithium ion battery packs are fairly efficient, I still prefer the AA battery standard, which allows me to obtain batteries as needed in most settings; a fresh set of alkaline (or freshly-charged) batteries will power most portables for hours on end.
  • Standard USB charging cable: If I can charge batteries internally, a USB charging cable can simply plug into my smart phone’s USB power adapter or the USB port on my laptop; no extra “wall wart” equals less weight and less annoyance.
  • ETM: Many new digital portables have an ETM function which allow auto-scanning of a radio band (AM/FM/SW), saving what it finds in temporary memory locations–a great way to get a quick overview of stations.  (As this function typically takes several minutes to complete on shortwave, I usually set it before unpacking or taking a shower. When I return to my radio, it’s ready to browse.)
  • Single-Side Band: While I rarely listen to SSB broadcasts when traveling, I still like to pack an SSB-capable receiver when travelling for an extended time.
  • RDS: Though an RDS (Radio Data System) is FM-only, it’s a great feature for identifying station call signs and genre (i.e., public radio, rock, pop, country, jazz, classical, etc.)
  • External antenna jack: I like to carry a reel-type or clip-on wire external antenna if I plan to spend serious time SWLing. Having a built-in external jack means that the connection is easy, no need to bother with wire and an alligator clip to the telescoping whip.
  • Tuning wheel/knob: Since I spend a lot of time band-scanning while travelling, I prefer a tactile wheel or knob for tuning my travel radio.
  • Key lock: Most radios have a key lock to prevent accidentally turning a radio on in transit–but with a travel radio, it’s especially important to have a key lock that can’t be accidentally disengaged.
  • LED flashlight: Few radios have this, but it’s handy to have when travelling.
  • Temperature display: Many DSP-based radios have a built-in thermometer and temperature display; I like this when I travel anytime, but especially when I’m camping.

While I don’t have a portable that meets 100% of the above travel radio wish-list, I do have several that score very highly.  I also rank my travel radios by size, as sometimes limited space will force me to select a smaller radio.

Here are a few of the radios I’ve used and/or evaluated for travel–I’ll break them down by size. Note that all portable radios have alarm/timer functions, unless noted otherwise.

My Tecsun PL-380 and the small Eagle Creek pack that also holds my Zoom H1 recorder, earphones, audio cables, external antenna, spare batteries and Kindle.

I often grab the Tecsun PL-380 for travel. It’s an ultra-portable that truly performs and even has a selection of six AM bandwidths.

Full-Featured Portable:

I have also been known to travel with an SDR (software defined radio), especially if travelling to an RF-quiet location where I could make spectrum recordings. While SDRs all require a computer (laptop) to operate, those best suited for travel derive their power from the same USB cable plugged into the PC. Neither of the SDR models below require a power source other than what’s provided by their USB cable.

The RadioJet is an excellent travel radio: it’s an excellent performer, über-rugged and is powered by one USB cable.

“Black box” radios (SDRs & PC-controlled radios):

  • RFSpace SDR-IQ • Pros: Small size, works on multiple operating systems (Windows, Mac, Linux) • Cons: front end can overload if close to strong signals
  • Bonito RadioJet • Pros: Great performance, low noise floor, good audio, flexible graphic interface; • Cons: Windows only, limited bandwidth on IF recordings, no third-party applications (note that the RadioJet is technically an IF receiver). Check out our full review.
The CommRadio CR-1

Tabletop:

Seriously? A travel-ready, full-featured tabletop–? Until last year, I would have argued that it was impossible to travel lightly with a full-featured desktop radio in tow.

My view changed when I got my hands on the CommRadio CR-1 tabletop SDR. Indeed, other than it being pricey ($600, as compared with $100 portables) this rig is ideally suited to travel!

The CR-1 has an array of features–most everything you’d expect from a tabletop radio–and even covers some VHF/UHF frequencies. Its built-in rechargeable battery not only powers it for hours at a time, but meets the strict airline standards for battery safety. The CR-1 can also be powered and charged via a common USB cable. It’s also engineered to be tough and is almost identical in size to the Tecsun PL-880.

CommRadioCR-1PowerKnobThough I’ve never needed to do so, you can even remove its resin feet to save still more space. Its only less than travel-friendly feature is the fact that it’s quite possible to accidently power up the CR-1 by bumping the volume button during travel–a problem easily remedied, however, by simply twisting an insulated wire around the stem of the volume knob (see photo).

The importance of a Go-Bag

The SpecOps PackRat

The Spec-Ops Pack-Rat

I keep a dedicated “go-bag” with radio and supplies–specifically, the Spec-Ops Brand Pack-Rat–packed and ready to travel, at the drop of a hat. Why? First of all, I know exactly what I’ll be taking, no need to ponder if I have everything.

Inside the bag, everything has its place: my portable SW radio, my Android tablet, my D-Star Icon ID-51a HT, DVAP (DV Access Point Dongle), my Zoom H2n Handy Recorder, earphones, charging cables, batteries, small notebook, clip-on wire antenna, etc.

If something’s missing, there’s an obvious blank spot in my bag. I also know exactly where and how it fits into my carry-on bag, so if it’s missing, it’s conspicuously missing. Since I’ve been using this go-bag, I’ve never left anything from my pack behind. Incidentally, this is how I pack the rest of my bag, as well: everything has its place, and any gap will draw my attention to exactly what’s missing.

SWL Travel Gear - Spec-Ops Pack-Rat Open

There’s another benefit to having a dedicated go-bag: when flying, before I place my carry-on under the seat in front of me or in an overhead compartment, I can pull the go-bag out of my carry-on and have my Android tablet close at hand with other electronics.  As an added bonus, when going through airport security, all of my electronics can be easily removed from my flight bag by taking out just this kit.

 SWL Travel Gear - Spec-Ops Pack-Rat Contents

I’ve had many versions of the Go-Bag over the years, and they’ve all done a great job. What I love about the Spec-Ops Brand Pack-Rat, though, is the fact that it’s military grade–very durable–opens with all of the main storage pockets on the inside, has a bright yellow interior which makes it easy to see the contents (even in the dimness of a night flight), and it’s just the right size to hold my usual travel gear. The Spec-Ops Brand Pack-Rat also carries a lifetime, no-matter-what, guarantee.

There are thousands of similar packs on the market, and you may already have one, but you should look for something with multiple storage pockets. Small packs I’ve used in the past that only had one or two main compartments made it easy to leave something out when packing.

When I spent a year in France during my undergraduate studies in the early 1990s, shortwave radio was my link with home. I would listen to the VOA–the only source of English I permitted myself to hear–like clockwork, each week. Today, although I travel with a smartphone which can tune in thousands of stations, I always choose to listen to radio. Besides, if the Internet goes down or if–heaven forbid!–your trip takes you into a natural disaster, it’s radio that you will turn to to stay safe and informed.

If you take anything away from this reading, I hope it’s that even when you’re presented with travel restrictions, you won’t hesitate to take your hobby, in the form of a portable radio and a few accessories along. It contributes measurably to the fun of travel, as I’ve discovered when I’m able to tune in local and international stations so different from those I hear at home.  Or sometimes, it’s just the opposite–it’s the chance to pick up a favorite broadcaster or program while you’re on the road.

After all, for me and other travelers like me, the world’s familiar voice is radio.

The Spec-Ops Pack-Rat: A new go pack for my radio gear

The Spec-Ops Pack-Rat makes for an ideal radio gear bag and easily accommodates the Grundig G3

The Spec-Ops Pack-Rat makes for an ideal radio gear bag and easily accommodates the Grundig G3 (Click to enlarge)

As I’ve mentioned before, I love to travel with one bag and efficiently pack my radio gear.

This year at the Dayton Hamvention, my good friend Eric, retiree of the Air National Guard, took me onto the nearby Wright Patterson Air Force Base. Eric is a good buddy and fellow ham, and for several years now, we’ve made it a point to visit both the National Museum of the US Air Force and Wright Patterson AFB while at the Hamvention. This year he was in need of some gear, so we visited the store where those on active duty purchase Air Force-approved gear and clothing. Being a bit of a pack fanatic, I of course quickly found the backpack section. I was searching for the perfect small radio gear pack, and I think I found it: The Spec-Ops Pack-Rat Organizer.
.

Pack-Rat2This little pack (roughly the size of a larger-format paperback book at 10″ high, 7.25″ wide x 3″ thick) is built very well–it seems nearly bullet-proof.  It immediately suggested several uses. Here are a few of its advertised features:

  • 14 separate storage compartments/ slots
  • A unique “inside-out” design which allows for instant open access while inside packs
  • 12″ gear-keeper leash for keys, lights, etc.
  • Clear business card/ID window
  • External mesh pocket
  • External accessory loops and carrying handle
  • “D”-ring attachment points for optional shoulder strap
  • Fully zippered perimeter allows for a 90° opening
  • Extremely tough Cordura® 1000D nylon exterior lined with heavy duty nylon pack cloth
  • Fully seam-taped interior
  • High-tensile nylon web attachment points and
  • Bar-tack reinforcements at critical stress points

One glance at the Pack-Rat, and I knew that one of its two largest interior pockets could hold my larger shortwave portables, the other could hold my Kindle Fire tablet, and there would still be plenty of room for wires, cables, accessories, and headphones.

PackRat3After bringing it home, I was simply amazed at exactly how much gear it could readily hold.  And indeed, this summer I’ve taken it on several trips; including my July trip to Belize for which I packed all of my gear into one small convertible carry-on pack (a small Timbuk2 Wingman).

Here’s the list of items I stashed in the Pack-Rat:

  • Grundig G3
  • Kindle Fire and power cord
  • Zoom H2n Handy Recorder with wind screen and mic stand holder
  • Eight AA batteries
  • Ear buds
  • Icom ID-51A HT and adaptor
  • 2 Cliff Bars (a guy’s gotta eat!)
  • 3′ stereo audio patch cable
  • two alligator clip leads
  • keys
  • pen, pencil, notepad
  • business cards

At this point, the little pack was full, but could close very easily and didn’t even bulge on the sides; even with all that (somewhat bulky) gear inside.

PackRat1Best yet, as I moved around in town, I could use the shoulder strap from my convertible backpack on the Pack-Rat, making it very easy to carry. Even though most of the internal pockets are open from the top, I never had anything fall out, even when the pack was upside down.  When the pack shuts, it seems to put enough pressure on the pockets to hold items securely. It’s bright yellow interior makes it very easy to see the contents even in dim conditions, such as on a night flight.

Spec-Ops packs are made with pride in the USA and obviously meet military standards for durability and construction. They also carry a lifetime warranty. You don’t have to visit a military base to purchase one, either: Spec-Ops has an online store where they carry their full product line. Spec-Ops Brand also has a store on Amazon.com. You’ll find the Pack-Rat on this page–note the number of positive reviews from customers.
