Let’s hit the field with the new lab599 TX-500 Discovery QRP transceiver!

Yesterday, I took delivery of a lab599 TX-500 Discovery QRP transceiver. Many thanks to Josh at Ham Radio Crash Course for shipping it here and Ham Radio Outlet for trusting me with this fine machine for the next couple of weeks.

I’ve been looking forward to this day for months–indeed, nearly a year.

A few initial impressions…

I won’t lie: the TX-500 is a gorgeous little transceiver and it’s solid.

The form factor is even a little smaller and lighter weight than I had imagined. I thought the multi-pin connectors on the side panels were the same size as, say, an XLR connector. Turns out, they’re much smaller and quite easy to use.

To put the TX-500 on the air, you’ll need to connect a minimum of three things: the power cable (terminated with Anderson Power Poles on the battery side), an antenna (BNC), and the speaker microphone. The TX-500 has no built-in speaker.

That’s all you’ll need if operating SSB. If operating CW, of course you’ll need to connect your key, but you’ll still need the speaker/mic connected for audio. That does make for quite a few things connected to the radio all at once.

The backlit display is high-contrast and easy to read indoors and in full sunlight. (And yes, that’s the Voice of Greece!)

In the spirit of full disclosure, I am not a fan of speaker microphone combos, but I’ll readily admit that the one with the TX-500 is about as good as they come. It feels durable and produces serious volume. The audio fidelity is obviously built around voice and CW, so it’s not ideal for HF broadcast listening, although it does have an external mono speaker port on the side of the mic.

If I owned this TX-500, I would order another speaker/mic 6 pin connector and build a headphone cable for broadcast listening and CW use. An easy fix.

For SSB though? The provided speaker/mic works. Indeed, it works quite well in the field because it’s so easy to hear.

There’s so much more to this radio, but I’ll save that for future posts and my full review. Let’s talk code…

Attaching a key

This morning, the first thing I did was fire up my soldering iron and make a CW paddle cable. (I hope HRO doesn’t mind–I didn’t exactly think to ask. Come to think of it, let’s just keep this between us, ok?). I soldered three wires to the supplied 5 pin connector (pins 1, 2, and 5).

To keep things simple, I hooked the TX-500 up to my Vibroplex single lever paddle which sports three terminals, making it easy to connect to the CW cable pigtail. Plus, heck, any excuse to play with the Vibroplex, right!?

CW

I was so eager to see how the TX-500 would perform on CW, that immediately after hooking up the key the first time, I checked POTA spots and worked two stations (WR8F in Ohio and NG5E in Texas) in rapid succession. Here’s a video of the exchange with NG5E:

Note that I used my iPad to make this video and, for some reason, the mic accentuated the clicking/clacking of my Vibroplex key. It’s not normally that pronounced. 🙂

CW memory keying

One of my complaints about the TX-500 when I read the final feature list a couple weeks ago was that it lacked CW memory keying. To me, this was a major negative because many POTA and SOTA activators rely on CW keyer memories to help with their logging workflow in the field. I certainly do.

lab599 must have been listening because I found out last week that they implemented CW memory keying in the most recent beta firmware update. Woo hoo!

I was sent the firmware file and this morning had no issues installing it in the TX-500 with the firmware application/tool.

After I sorted out how to record and play back the CW memories using the top row of function buttons, I was ready to hit the field!

I packed the TX-500, and headed to the Blue Ridge Parkway for a POTA activation!

CW POTA activation

I only had a brief period of time to fit in an activation today, so I kept it simple by going to the Folk Art Center which has a number of picnic tables. A park ranger once asked that I not hang an antenna in a tree at this particular site, so I used my Wolf River Coils TIA portable vertical antenna.

The Wolf River Coils TIA

Truth is, I feel like I always get more mileage out of a wire antenna than a vertical when running QRP, but I worked with what I had.

I started calling CQ on 7063 kHz and within 10 minutes worked five stations.

The CW memory keyer worked well. There is currently a two second delay before the TX-500 begins transmitting, but I’m guessing that can be fixed in a future firmware update.

Here’s a short video of the TX-500 memory keyer in action:

The TX-500 uses a relay to switch between transmit and receive, so you can hear clicking in the background. I had the recovery time set to the shortest interval which resulted in the maximum amount of clicking. Good news is the TX-500 body is so solid, the clicking is quite soft and muted–about the softest clicking I’ve ever heard in a transceiver. You could, of course, minimize relay clicks by setting the T/R delay to a higher number.

I’m very impressed with the TX-500’s low noise floor and filtering. Signals just seem to pop out of this thing.

I played radio for a while longer but was eventually chased off by a thunderstorm.

I must admit: for the first time, I wasn’t terribly worried if it started raining and the radio got a bit wet. The TX-500 is weather-resistant so can certainly cope with a sprinkle.

More to come!

I’ve set a personal goal to take the TX-500 to the field seven days in a row. I’m not entirely sure that’s realistic as I see the amount of thunderstorm activity in the forecast. Still, one must have goals, right? Plus, any excuse to hit the field and play radio!

Please comment if you have questions about the TX-500. I’ll do my best to answer as many as I can!

Parks On The Air: Finally biting the CW bullet!

14 Replies

I mentioned in a previous post that one of my Social DX goals was to activate a Parks On The Air (POTA) site in CW (Morse Code).

Mission accomplished!

Yesterday, I mustered up the nerve and drove to the Blue Ridge Parkway (site K-3378 in POTA).

My wife and kids were knee-deep in another project so I planned to go solo until my dog, Hazel, caught wind I was leaving with my radio backpack in-tow. Always ready for a hike or road trip, she jumped in the car the moment I opened the door.

I’ll admit it: I was nervous. I had the same jitters I had the first time I spoke in front of a large crowd.

In the end, though, I really had nothing to fear. The POTA community is a very kind, courteous, cohesive and supportive group of radio operators.

I picked the Blue Ridge Parkway as my first site not only because it’s so convenient to where I live, but it’s also one of the most activated parks in the POTA program. I knew a BRP activation wouldn’t attract a mad pile-up of park hunters because everyone in POTA has this one in the books already.

My full radio kit–including my KX2 transceiver, KXPA100 100W amplifier, two antennas, Heil headset, two battery packs, chargers, and all accessories–is packed in my Red Oxx C-Ruck and always ready for action. I grabbed the full kit, although in truth I only needed the KX2, my CW paddles, coax cable and antenna.

Conditions were rough yesterday. Propagation was pretty good, but there were pop-up thunderstorm everywhere in the region, so the bands were very noisy with constant static crashes. Herein lies one of the great things about CW: you can use a filter width so narrow that it doesn’t affect you as much as it does operating phone.

Because I had limited operating time, I deployed the Wolf River Coils TIA portable antenna. It takes me all of 4 minutes to set up.

I got on 40 meters, started calling “CQ POTA” and the next thing I know I had 13 stations logged.

My nerves dissipated quickly after I logged the first couple of contacts and I was even looking forward to stations answering my call. The operators were also incredibly patient with me and two of them even followed me to higher bands and made contact there.

Hazel the dog staring at my portable logging computer.

Hazel was a bit upset this activation didn’t include a hike, so several times she insisted on “helping” with the logs as I sweated it out!

All-in-all, I logged 17 stations in one hour on three bands using about 10 watts of power.

I deployed my station quickly, and I packed it up quickly. A pop-up thunderstorm, once again, chased me off the air. That’s okay, though, because I was already feeling pretty chuffed about bagging my first CW activation.

If I’m being completely honest here in front of my community of radio enablers, as soon as I arrived back home, I started mentally putting together a super-compact CW activation kit built around an LnR Precision MTR3B transceiver. I’ve always wanted one of these little CW-only transceivers to carry in my EDC bag for impromptu field radio fun, but never could justify it. Until now! 🙂

Upping my CW pile-up game with Morse Runner

4 Replies

I mentioned in a previous post that I’ve been practicing my CW (Morse Code) skills in an effort to build confidence to do a Parks On The Air (POTA) CW activation.

But how in the world do you practice handling a CW pile-up without actually going on the air–?

I’m glad you asked!

My DXing and contest friends have often touted an amazing free PC application developed by Alex Shovkoplyas (VE3NEA) called Morse Runner.

Morse Runner’s goal is simple: teach you how to manage a CW pile-up.

In short? It’s incredibly effective!

When you start a Morse Runner session, the application emulates the sound and atmosphere of the HF bands in CW mode (meaning, a narrower filter setting). It’s very convincing.

Instead of using a key to send a CQ, the Morse Runner interface emulates a contest logging system where a computer generates your CQ and sends the signal report you record for a station.

Screenshot of Morse Runner (click to enlarge)

You simply set a few parameters like your call sign, max CW speed, pitch, and bandwidth, then press the “run” button and call CQ by pressing the F1 key on your keyboard.

Within a few CQ calls, you’ll hear anywhere from one to several stations answer your CQ (depending on your settings). Your job is to then start logging those stations accurately from the pile-up. If you reply with an incorrect call, the other station will repeat their call until you correct it.

Morse runner has band condition settings you can select like: QRN, QRM, Flutter, QSB and–yes–even LIDs.

Quite often I’ll accurately reply to a weak station and they’ll send “AGN?” and I repeat their report until they copy it.

Morse Runner is so convincing that when I’m in the middle of a big pile-up, I honestly forget I’m communicating with a computer application! I get some of the same excitement and the–let’s be frank–anxiety I would get on the air during a live CW pile-up.

If you select the “LIDs” Band Conditions setting, it’ll crack you up with how accurately it portrays annoying operators who either deliberately or unintentionally try to interfere!

Here’s sample audio from a session this morning:

The screen shot above shows the settings I used for this very tame session with no large pile-ups. If you’re a seasoned CW contester, pump up the speed and the activity level then you’ll feel like you’re on the Heard Island DXpedition!

In short: Morse Runner is giving me the courage to do my first CW park activation. I highly recommend it!

Radio Waves: Stories Making Waves in the World of Radio

Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers. To that end: Welcome to the SWLing Post’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Tony, Mike Terry, and the Southgate ARC for the following tips:

Sealand’s caretakers (Boing Boing)

Sealand is an unrecognized micronation off the coast of England, established in the 1960s and issuer of stamps, passports and occasional offshore business shenanigans (“BECOME A LORD“). But Sealand is also a rotting sea fortress in need of constant maintenance. Atlas Obscura met the two caretakers who spend two weeks at a time doing what they can to keep the statelet running smoothly. Dylan Taylor-Lehman’s feature article is a great introduction to the place, if you’re not familiar with it or its wild history.[…]

How Bitcoin Is Like Ham Radio (Coindesk.com)

Understanding bitcoin is difficult. And so we cast around for the perfect metaphor. Bitcoin is email. Digital gold. eCash.

Here’s a new one. Bitcoin is ham radio.

Bitcoin is old-fangled. It takes days to download the Bitcoin blockchain, just like it took forever to download software back in 1994. In an age of instant email and real-time Zelle payments, a bitcoin transfer takes 60 minutes to safely settle. It’s more volatile than gold, a relic of our previous monetary system. Thousands of computers are constantly replicating each others’ work, making it vastly inefficient. And lastly, there’s no privacy. Like a medieval marketplace, everyone can see everybody’s holdings.

All of these features are anachronistic. But they do sum up to something unique. What exactly is that thing?

A ham radio allows its operator, otherwise known as an amateur radio operator, to use certain bands in the radio spectrum to communicate by voice or code. This is an old technology. Italian inventor Guglielmo Marconi became the first ham radio operator in 1897 when he transmitted Morse code across Salisbury Plain in England.

It seems odd that something as archaic as ham radio continues to exist in a world with email, Snapchat, iPhone and Facebook. A ham transmission can only be used over a couple of kilometers. No emojis. No video. No gifs. Forget about privacy! Anyone can listen into your radio conversation.

Yet, ham radio is a very active niche. Associations all over the world keep the hobby going. According to the American Radio Relay League, there are some 764,000 ham radio operators in the U.S. Japan has more than a million. The International Amateur Radio Union pegs the global number of amateur radio licensees at 3 million.

Like ham radio, Bitcoin is for hobbyists. I’m not talking here about all of the frenetic speculators who keep their coins at Coinbase. I’m talking about users who can run a full node, use Lightning, securely store their own coins and make frequent transactions with the stuff. This pool of bitcoiners is tiny. It’s probably smaller than the number of active licensed ham radio operators.[…]

CW Training Program (Southgate ARC)

In this video Howard WB2UZE and John K2NY of the Long Island CW Club talk to David W0DHG about their CW training program

The club started in 2017 offers over 45 hours of CW classes EACH week, and has grown to over 600 members from all 50 states and 15 countries all over the world.

50 Years Ago, Casey Kasem Began Counting Down The Hits On American Top 40 (NPR)

On July 4, 1970, the countdown started. Originally hosted by Casey Kasem, American Top 40 played “the best selling and most-played songs from the Atlantic to the Pacific, from Canada to Mexico,” as he stated on the first program broadcast 50 years ago as of tomorrow.

On any given week, American Top 40 could feature a ballad, next to a country song, next to a funk song, next to a rock song. The show became a national obsession but 50 years ago, it was considered a risky idea.

“You remember, at the end of the ’60s, Top 40 was not the most popular format,” Casey Kasem told NPR in 1982. “And here we were coming along with a show called American Top 40, and people said, ‘You must be nuts!’ “[…]

Hamvention Special: Begali offers free shipping to US

2 Replies

My Begali Simplex paddles have served me so well and perform flawlessly.

If you planned to pick up a Begali key at Hamvention this year, you’re in luck.

I just found out through SWLing Post contributor, Grayhat, that in honor of Hamvention, Begali is offering free shipping to the US and 50% off shipping to the rest of the world. This promotion ends tomorrow.

Since Begali keys are heavy by design, this is a great deal on shipping!

The Begali family not only makes the best keys, but they are amazing friends to so many in the radio community.

I purchased my Begali Simplex paddles, pictured the top of this post, at the 2008 Hamvention. I absolutely love them. While they’re one of the least expensive hand-crafted precision keys in the Begali line-up, I think you would find they perform better than any other paddles on the market anywhere close to this price point. I never miss a visit to the Begali booth to try out all of Piero’s latest designs. Begali is always one of the busiest vendors at Hamvention.

“The Spy” dramatizes careless use of covert QRP HF CW transmissions

1 Reply

Many thanks to SWLing Post contributor, Ed, who writes:

The new 6-part Netflix series ‘The Spy’ about the Mossad agent Eli Cohen (played by Sacha Baron Cohen) who infiltrated Syrian military intelligence from 1962-1965 dramatizes his careless use of QRP HF CW transmissions in Damascus, which were DF’d to track him down.

SWLing Post readers might find the series interesting, especially segments depicting Mossad’s use of covert QRP HF CW transmissions.

Radio-savvy viewers will find unintended humor in the use of a transistor AM radio circuit board, tiny batteries, and no antenna(!) to send CW messages from Damascus to Israel–and in the comical depiction of a Soviet/Syrian radio HF DF van. You’d think a TV series with star power could’ve found a willing ham or film crew member to lend some basic technical expertise.

Thanks for sharing, Ed! I’m sure this is a great series. And, yes, I suppose this wouldn’t be the first time the movie industry made an attempt at authenticity but fell just a little short! Since that’s such a key part of the film (no pun intended!), you would think they could have consulted an expert to make the setup authentic while preserving the integrity of the scene.
