Hamvention Highlights: The Palstar TR-30A EMP, an EMP-hardened HF transceiver

Each year at the Dayton Hamvention I enjoy checking out the latest radio products and services. This year (2019) I found an exceptional number of innovations and will share these in Hamvention Highlights posts. If you would like to check out 2019 Hamvention Highlights as I publish them, bookmark this tag: 2019 Hamvention Highlights

And now for our first highlight…

The Palstar TR-30A EMP

I’ve long been a fan of Palstar, a US company known for their fine antenna tuners and the classic R30 series HF receiver.

At the 2013 Dayton Hamvention, Palstar showcased a prototype HF transceiver called the TR-30. I posted a note about this at the time on my ham radio blog, QRPer.com. The TR-30 never seemed to make it to the market, but that’s not surprising considering the Elecraft KX3 and a number of other QRP transceivers were released the following year.

This year when I approached the Palstar booth, I found a new prototype transceiver: the Palstar TR-30A EMP.

This TR-30 iteration will, without a doubt, have a unique place in the radio market since it has been designed to withstand electromagnetic pulses (EMPs). To be clear, I know of no other transceivers on the ham radio market that are EMP hardened.

Post readers might recall a primer we published about how to protect your gear from EMP pulses (click here to read).  I believe taking some simple precautions to protect gear from natural or man-made EMPs is simply a sound practice. In fact, I keep one complete rig stored in an EMP-proof container as described in our primer.

The Palstar TR-30A EMP requires no external EMP shielding or special handling/storage. It will be natively EMP-proof, even while hooked up to an antenna and without an RF ground attached.

I spoke with Paul Hrivnak (N8PH), President and CEO of Palstar, at Hamvention and he shared a few details about the Palstar TR-30A EMP:

  • The transceiver will be general coverage and will be able to operate on all of the HF ham radio bands.
  • It will have a very simple set of functions–at this point, he doesn’t even plan to have dual VFOs.
  • The output power will be 20 watts.
  • The front panel controls will be very simple and intuitive.

The TR-30A EMP’s unique internal antenna tuner will–if I understand it correctly–be able to match pretty much any load.  It will have manual controls, but will be digitally controlled. Paul said that the ATU is being designed so that a satisfactory match can be found for any make-shift field antenna. I can’t wait to check it out for myself because I hold Palstar in high regard when it comes to antenna tuners.

Of course, from the ground up, the TR-30A EMP will be hardened against EMPs.

He hopes the Palstar TR-30A EMP will be in production by the end of 2019 and retail for $1,100 – 1,200 US.

Of course, I will post any news and updates about the Palstar TR-30A EMP here on the SWLing Post. I will also plan to review and evaluate the transceiver when it hits the market.

Cyclone Fani: How Ashok prepared for this powerful storm

Category 4 Cyclonic Storm Fani was the strongest tropical cyclone to strike the Indian state of Odisha since Phailin in 2013.

Many thanks to SWLing Post contributor, Ashok Shankar Das, who shares the following post from his blog SWLDAS:

The extremely severe cyclonic storm #Fani recently visited Odisha. It is Peculiar to have a Cyclone in this time of year. Though history says earlier there are some cyclones hit Odisha coast during this summer season.

[…]I have seen several Cyclones including #1999SuperCyclone . Though Super cyclone has done a lot of damage, this one is no less. Wind speed of 200kmph with gust 220 to 250 kmph ripped everything in its path. major damages to infrastructures like power grids, cell towers under construction buildings are name a few.

My Preparedness

The CountyComm GP5-SSB

See this SWLING article–I was runner-up in that challenge. My preparation for Cyclone Fani was as per I have described. Well Not all. I have charged emergency light, arranged candles and lantern. Stocked Biscuits and Flat rice. Stored around 15Liters of drinking water. Emergency medicines and fully Charged 3 Baofeng Walkie Talkies.

The GP5SSB I got as a gift from SWLING Post, put new battery in it. I have downed external antennae for HF and VHF. Baofeng handys are quite good as scanner. I monitored HAM band so I could know the situation in surrounding area and also if situation arises I could give a distress call to Nearby monitoring person. But that situation didn’t arise.

HAM volunteers from WBRC started their communication service since 5th May. They Have setup a VHF in state control room at Bhubaneswar, ADM office Puri and Khurda.
Since 5th may onward I was monitoring and in QSO with VU2IPL(Suresh). VU2FTP VU2XRY VU3YDA and VU3OXI are handling the communication between Puri, Khurda and Bhubaneswar.[…]

Click here to read Ashok’s full post on his blog, SWLDAS.

Thank you for sharing this, Ashok and we’re very pleased that you made it through this extremely dangerous storm well-prepared. It sounds like your community has a good ham radio communications network at the ready as well.

Ashok, you are reminding me that it’s time to dream up another Virtual Radio Challenge along with an enticing prize. I’ll start putting one together! Perhaps I can find a prize at the Hamvention this week. Stay tuned…

Terry remembers monitoring an eventful Sydney to Hobart yacht race

Many thanks to SWLing Post contributor, Terry Cominos, who shred the following story following our recent post about the Sydney to Hobart yacht race. Terry writes:

Here is my story…

It must have been 20 plus years ago whilst monitoring the Sydney to Hobart yacht race on my AOR AR3000.

Around midnight the yacht “Mem” announced a man was lost overboard. They were turning back to find him. The Captain of the oil tanker “Ampol Serel” on his way to Sydney declared he was turning back to assist in the search.

It was a long night with several yachts searching and the “Young Endeavour” providing radio relay support.

More than an hour passed before the “Ampol Serel” arrived on the scene with its powerful search light.

The search was hampered by a swell yet before first light “Ampol Serel” picked up a reflected flash off a life vest.

The sailor was eventually found by a competing yacht and taken on board where he was examined and treated for hypothermia by a doctor onboard.

Several years later I visited the Australian Maritime Museum where the life vest is on display.

That morning I learned a lot about the sea, radio and human nature…

Thank you for sharing this, Terry, and reminding us  that those of us who monitor radio sometimes have a front row seat to events as they unfold.

Source: OneTubeRadio.com

I recall this 1957 Hallicrafter ad from Boy’s Life magazine which of course implies that we may even be in a position to help.

The thought of hearing or assisting–remote as it may have been–certainly had an influence on me when I first started exploring the shortwave bands from my bedroom with a Zenith Transoceanic some forty years ago.

Thanks again for sharing, Terry.

Midland WR120 Review: Aaron says weather radios, like smoke detectors, are something we all need

Storm with lighteningMany thanks to SWLing Post contributor, Aaron Kuhn, who writes:

“Weather radio? I’ll just use my cellphone for alerts.”

If you’ve ever uttered or thought the above words – take heed.

Late last week I awoke at around 12:30 AM to the sound of some incredibly strong winds outdoors. Glancing down at my completely muted phone, I opened up my text messages to reveal a Tornado Warning. In a panic, I threw on some clothes, gathered a dog harness and leash and made my way the pantry closest for shelter.

Then I checked my phone again – and realized that tornado warning was from 30 minutes ago and already expired. Crap. That was too close for comfort. I promptly went on to Amazon and ordered the Midland WR120.

I unboxed and set the radio up yesterday and I’m quite happy with it.

The first thing I suggest doing after initial setup is turning off the button beeps which are incredibly annoying. Past that, I’ve found the radio perfect for my needs of setting it on a window sill and (hopefully) forgetting about it until it alerts me to any nearby danger.

Since SAME Alerts work on a county basis, I was very happy to discover this radio allows you to disable certain kinds of alerts that may not be relevant to you.

One thing that I think Midland should include in the box printed (instead of ads for weather apps they don’t publish anymore!) is the “Editable Events list:
http://midlandusa.com/wp-content/uploads/2011/11/Editable-Events.pdf

By default, the radio doesn’t allow you to turn off 30 some events, including Tornado Warnings among them – this is a good thing in my opinion! However, it is a bit concerning when you first go to setup the radio and realized Tornado Warning is missing in the alert list. The reason for this is because this is one of the 30 some alerts you can’t disable.

Overall I’m happy with the radio, and hoping it’ll never fire off in the middle of the night on me any time soon – but I know it’ll be a lot more reliable than my cellphone prone to being muted.

I view weather radios like smoke alarms now, it’s stupid for you to not have one. I wasn’t expecting Tornadoes in November in Southeastern Pennsylvania, but apparently nature is one to surprise us continuously.

Thank you so much for sharing your story and your WR120 review, Aaron.

I love this quote: “I view weather radios like smoke alarms now, it’s stupid for you to not have one.” I agree completely!

A few weeks ago, there was an alert sent to every phone in the US all at the same time. I received my alert nearly 30 minutes late. Mobile phones and their networks are pretty amazing technology, but they’re not flawless.

We are so lucky to have a robust weather radio broadcasting infrastructure here in the US and Canada. An inexpensive radio like the WR120 will deliver weather alerts reliably and give you a preparedness edge.

And thank you for mentioning the number of events you can edit out of the alert system. No sense in receiving alerts you don’t need.

In addition, some weather alert radios default to receive alerts from counties and regions surrounding your own. I would suggest turning those off–limiting the alert area to your own county–else you could get a lot of alerts that don’t pertain to your location. Using the smoke detector analogy, receiving alerts from surrounding counties is much like putting a smoke detector directly over your stove! You’re just asking for false alarms. 🙂

Thanks again, Aaron, for the important PSA!

Keep in mind as the holiday season approaches: weather radios make for life-saving, affordable gifts.

Steve searches for a USB-powered battery charger for solar recharging

Many thanks to SWLing Post contributor, Steven Crawford, who writes with the following inquiry:

[I’m searching for] good quality USB powered battery chargers for AA and D size rechargeable batteries.

Wall outlet chargers are common but quality USB powered battery chargers appear much less common…less common than the packable solar panels with USB ports such as Anker’s, that could be used to power them. Ideally the charger should handle Nicad’s, NIMH and Ii-on but have standardized on AA, AA + D adapter sleeves, and D batteries for my storm supplies.

If I understand correctly, you’re searching for a good qualityUSB-powered battery charger that supports multiple battery chemistries (nickel-cadmium, NIMH and lithium ion) so you can recharge AA, AAA and D batteries with a portable solar panel.

I’m hoping SWLing Post readers can offer some suggestions.

I’ve also looked into this type of charger for both Ears To Our World and my own personal use when off-grid in the summer. I’ve never found one that truly supports all of the battery chemistries you mentioned. The one I’ve used (an EBL) works quite well, but only supports NiMH AA and AAA batteries. As you mentioned, you can use D cell sleeves with the AAs.

EBL makes a number of USB chargers that can be found by searching Amazon. This one–an EBL Quick Charger (affiliate link)–can recharge NiMH batteries within 40 minutes and I’ve personally used one. I’ve been pleased with EBL batteries as well.

I never use nickel cadmium rechargeable batteries at this point, so really don’t know what’s available on the market.

I have found that there are a number of USB-powered lithium battery chargers, but typically for specific lithium cell configurations like 18650, 16340, 14500, 26650, etc. Some of these inexpensive chargers have magnetic contacts that can fit almost any battery type and on Amazon and eBay they claim to recharge multiple battery chemistries, but frankly I’m quite skeptical. These $9 devices don’t seem to have a way of detecting battery chemistry, thus I’m not sure how they would adjust the charging cycle accordingly. Perhaps I’m incorrect in this assumption?

Other than using Powerfilm solar NiMH battery chargers (I can recommend these) which are incorporated in their folding panels, I’ve never charged batteries directly from a solar panel. Typically I have a 9ah or larger 12V battery floating between the PV panel and the charger.

I’ve found that using a 12VDC charger–like this–that’s pulling power from a 12V battery is simply a little more efficient, faster and reliable than charging directly from a small PV panel. Since I always have 12V batteries on hand when off grid, it’s a simple solution for for my system.

Everyday Carry: My EDC packs and radio kit

SWLing Post contributor, Matt, writes:

Thomas: I know you’re a self-proclaimed pack geek and so am I! You published a photo of your EDC pouch in a post last year. Just a teaser really! What is that pouch and I assume you have a larger carry bag as well? Can you provide more details? I’m ever revising and honing my own EDC pack. Any details would be appreciated.

Thanks for your question Matt!  Besides radio, you’re bringing up on one of my favorite topics: packs! You may regret having asked me!

Yesterday evening, I snapped a few photos of my EDC (Everyday Carry) bag and the pouch you’re referring to. Your inquiry is prompting me to consider publishing a more detailed look at my EDC gear–especially since radio is such an important part of it.

I do carry a larger EDC bag at all times. Typically, this is the Tom Bihn Pilot:

For years, I carried a Timbuk2 messenger bag, but it didn’t have the type of organization I prefer in an EDC bag. My EDC bag must be rugged, water resistant and accommodate my 13″ MacBook Air while still having enough depth to comfortably fit the rest of my gear.

I’ve been using the Tom Bihn Pilot for almost a year and have been very pleased. The Pilot is an investment to be sure, but (like Red Oxx) Tom Bihn construction quality is superb and comes with a lifetime warranty.

It’s amazing how much gear will comfortably fit inside without making the bag bulge. The Pilot also has a dedicated water bottle pocket in the middle of the front panel. While I do carry water, it primarily houses my never-leave-home-without-it Zojirushi Stainless Steel Mug (affiliate link) which is filled with piping hot dark roasted coffee!

I also use the water bottle pocket to hold full-sized handled VHF/UHF radios. It accommodates either my Kenwood TH-F6, Yaesu FT2D, or Anytone AT-D868UV perfectly. Indeed, all of the front pockets will accommodate an HT since the zippers terminate at the top of the bag. Long antennas can easily poke out while the zipper still seals 99% of the opening.

The Pilot has one main compartment that houses my 13″ MacBook Air laptop.

The Pilot laptop compartment is spacious and has two built-in pockets opposite the laptop sleeve: one of these pockets (the one on the right in the photo above) holds my EDC pouch, the other holds first aid supplies, an Olight SR1 flashlight and Nitecore LA10 latern (affiliate link). My laptop is in a TSA-friendly Tom Bihn Cache.

While the Tom Bihn Pilot is the bag I use most days, also use a Red Oxx Micro Manager and–when I need 25 liters of capacity–the Tom Bihn Synapse 25.

I pack most of my EDC gear in pouches, so moving from one bag to another takes me all of one minute.

My EDC pouch is the Maxpedition Fatty Pocket Organizer (affiliate link). I love this pouch because it’s incredibly durable, affordable and opens like a clam shell to lay flat.

Everything has its place. Not only does it hold my Yaesu VX-3R handheld, but also a multi-function knife, a Leatherman Style PS tool, clippers, earphones, multi-bit screwdriver, USB stick, notepad, spare VX-3R battery, a mini first aid kit, titanium spork, and much more! Someday I’ll pull the whole thing apart and note each item.

Why do I choose the Yaesu VX-3R? First of all, it’s compact. This HT is so small it’ll tuck away anywhere. Not only is it dual band, but it’ll also receive the AM broadcast band (even has a little ferrite bar inside), the shortwave bands, and the FM broadcast band.

The mini rubber duck antenna will work in a pinch, but I also carry a flexible Diamond SRH77CA in the floor of the Tom Bihn Pilot’s main compartment.

When I attach the Diamond antenna, it significantly increases the VX-3R’s capabilities.

While the VX-3R does cover the HF bands, don’t expect amazing performance. Selectivity is poor, but sensitivity is adequate. For a shortwave antenna, I carry a short length of coax: one end is terminated with an SMA connector, the other has the center conductor exposed.

I also carry a short alligator clip cable which I clip to the exposed center conductor and then to a length of wire. The end result is a very cheap, flexible and effective portable HF antenna!

Someday, I’ll take everything out of my EDC pack, inventory the contents and publish a post about it. Somehow, that’ll please my inner pack geek! I’m overdue a review of the Tom Bihn PIlot and Synapse 25.

Guest Post: Hans reviews the Freeplay Lifeline and Unity self-powered radios

Many thanks to SWLing Post contributor, Hans Johnson, who shares the following guest post:


Irma-induced Radio Reviews

by Hans Johnson

The primary disaster we face here in Naples, Florida, is hurricanes.  Naples had been spared for over a decade until Irma.  So while I had prepared, I had not needed my supplies or equipment for quite some time.  This included the radios.

I went into Irma with two Freeplay solar and windup radios, a Unity and a Lifeline.  I got these radios probably over a decade ago.  As part of some work I was doing with VT Communications (now Babcock), I was involved with a radio project called Sudan Radio Service.

Both of these radios were being given to listeners as part of this project.  I wanted to have a better understanding of what they faced.  I had some conversations with Freeplay in London, explaining who I was and why I wanted these radios.  During a visit, I was able to purchase both sets with the proviso that I not sell them.

I checked them both out at that time with my focus being on shortwave as that is how Sudan Radio Service was then transmitted.  They were ok at picking out the strongest stations but that’s about it.  I never really needed or wanted to use the radios day to day.  And then Irma struck.

We left Naples on Saturday when we received a mandatory evacuation notice.  The storm struck on Sunday and we returned on Monday.

We were spared.  Many lost everything.  Some lost their lives.  We had a lot of trees down and some roof damage, but nothing substantial.  But we had no power.  Water had to be boiled.  Sewage was backing up in places because the lift stations had no power.  The stop lights were out (this was a real danger, many did not treat them as four-way stops and just blew through them.  But you never knew who it would be.)  A curfew was in place.  The cell phone system was in really bad shape.  I could not call or text my brother across town, let alone get access to the Internet via cell.

This link will give you an idea of what we came back to.  I am the guy sawing wood at 1:47.  (Lesson learned, have two chainsaws in case yours blows a gas line):

http://abc7ny.com/weather/watch-josh-einiger-reports-from-naples-florida/2391120/.

I had blown up some air mattresses before the storm so we slept on them on the screened porch.  I saw the Milky Way from Naples for the first time.

We wanted information and also a bit of entertainment.  Television was out of the question.  The HDTV stations are hard to receive with a great antenna and set in the best of times where we live.  So a battery-operated TV would have been a waste.  Radio was the only game in town, so it was time to put the emergency radios in service.

Sudanese Listeners Receive Unity Radios (Source: Lifeline Energy)

Both of these analogue dial sets cover AM, FM, and shortwave.  The Unity covers 3-22 MHz, the Lifeline just goes up to 18.  The former covers the old American AM band and the latter the new one.   The Unity uses a whip antenna and has a fine tuning knob.  The Lifeline has a bendable wire that fits into the carrying handle and came with an alligator clip and a length of wire.

Ideally, one would be listening a set that has been charged via the solar cell or listening with the set in the sun.  The last place I wanted to be was in or near the sun.  Trying to charge the set and then listen to it is difficult in practice.  It seems that the ratio was about one to one.  15 minutes in the sun would get you about 15 minutes of immediate listening.  It doesn’t seem that the batteries will hold a charge for long periods of time.  I could not charge them during the day and expect to turn them on the next morning, which was the peak time of day for radio to be transmitting local information.  The ratio for using the hand-crank was better, but I grew tired of cranking quite quickly.

I was interested in local stations, so shortwave was not a factor.  We only have a few local AM stations in Naples and I could not receive them (Irma knocked off or damaged a number of stations.)  I tried FM.  Even with the antennas retracted, both sets were overwhelmed by the local stations with certain stations bleeding through over much of the dial.  I could receive some strong, local stations.  With the outlet at Marco Island off and the other apparently on reduced power, receiving NPR was out of the question.

Given how many sources of information I was cut off from, my flow was greatly reduced.  My ignorance increased and learning vital information was hit or miss.  A neighbor told me about the boil order.  Passing on information was difficult.  When we got power I wanted to tell my brother, but the only way to inform him was to drive to his house.

One result was that I put these sets away and broke out my old Sony

ICF-7600GR and used it instead.  I guess I could have used it until I ran out of AA batteries.  I had plenty on hand and can easily afford them.  But that is hardly the case in Southern Sudan and many other places.

The Lifeline came with a few stickers on it that I could not read when I got the set.  Now that Goggle translate is so good I can read them.  They say in part:  “Everyone has the right to receive information,”  “Everyone one has the right to search for, receive, and deliver information.”

The real result of the test was a greater appreciation for how good I have it in many ways.  With regards to information, I have many sources and can readily receive it and pass it on.  It increased my respect for services like Sudan Radio Service and how important they are.  But most especially, I have a much greater admiration for listeners using these sets and what is surely their perseverance, patience, and determination to get information.


Many thanks for your field report of the Freeplay Lifeline and Unity, Hans!

I’m happy to hear you had no serious damage post-Irma. So many in the SWLing Post community have been affected by hurricanes this season.

I have never, personally, reviewed either of these Freeplay units–both are now discontinued and have been replaced with other models at Lifeline, I believe. As you state in your post, these radios are only available to humanitarian organizations. Through Ears To Our World, I have considered acquiring Lineline Energy (Freeplay) radios in the past. However, their radios tend to be rather large in size–we tend to go with smaller receivers that can easily fit in suitcases. In the past we’ve been very happy with the Grundig FR200 (Tecsun GR-88). 

The Lifeplayer MP3

Last year, we did purchase a Freeplay Lifeplayer to test. The hand crank charging mechanism is very robust, though quite noisy. The radio is digital, but performance is mediocre and tuning couldn’t be more cumbersome (5 kHz steps, no memories, only a couple of band steps.  Tuning to your favorite station could literally take a couple of minutes, depending on where it is on the band. When you turn off the radio (or it runs out of power) you’ll have to re-tune to the station again. That’s a lot of extra mechanical wear on the encoder. The real utility of the Lifeplayer is the built-in MP3 player and recorder–a brilliant tool for rural schools. Also, it’s robust and can take abuse from kids much better than other consumer radios.

Your main point, though, is spot-on: these radios serve their purpose, but we radio enthusiasts are incredibly fortunate to have much better grade equipment to take us through information backouts.

Thanks again for your review, Hans!
