BG6LH Designs a Board for Integrated Yaesu FT-817/818 FT8 Operation

4 Comments

Many thanks to Cao (BG6LH) who writes:

Hi, Thomas!

I would like to share my QRP FT8 kit for Field Operation.

A long time ago, I was seeking the most lightweight QRP kits for FT8 field operation. My goal was to have just one radio, one antenna, one phone, without too many cables, boxes, etc.

Finally, I designed a PCB. It is a Bluetooth DIGI Adapter and can be mounted on the rear panel of my FT-818.

Just plug it to the DATA and ACC jacks. It can be powered by ACC jack’s 13.8V Pin.

It works well with FT8CN, an android FT8 app.

Now, my dream has come true!

My Antenna was a so-called GAWANT, designed by JF1QHZ, I guess it’s a simple Vertical EFHW. I built it with a 1.2 meter rod.

It’s working on 7~28MHz bands, not very efficient, but so small and portable.

For FT8 QRP POTA, field operation, all of these components can be put in a small bag, and deployed in minutes.

I shared my PCB design on Github. If anyone wants to modify it, you are welcome to do so!

Thank you for sharing this, Cao. This is absolutely amazing and an incredibly clever design! I suspect a lot of FT-818/817 enthusiasts will make this same build via your design!

Thank you for reaching out and for sharing your work with the QRP community!

Pairing the Yaesu FT-817ND and Chelegance MC-750 at South Mountains State Park

3 Comments

After completing a lively little POTA activation at Lake James State Park (K-2723) and then Table Rock Fish Hatchery (K-8012) on the morning of Monday, July 31, 2023, I decided to squeeze in one more POTA adventure on what became a mini rove.

Since nearby Tuttle Educational State Forest is closed on Mondays in the summer, I chose to visit South Mountains State Park (K-2753) instead–it was only a few minutes further afield than Tuttle.

After leaving Table Rock, I picked up a quick lunch in Morganton and drove to the main entrance of South Mountains and set up at the equestrian picnic area.

South Mountains State Park (K-2753)

 

The weather that day was beautiful and so was the drive.

I decided to deploy my Chelegance MC-750 this time, just to shake things up a bit. If you know me, when I do little roves like this, I typically like to use different radios and/or antennas at each site.

I paired the MC-750 with my Yaesu FT-817ND. My reasoning for picking the ‘817 was because I could use the SO-239 connection on the back of the radio. The new cable assembly/feedline I was using had PL-259s on each end.

Speaking of the new assembly, at the Dayton Hamvention this year, I popped by the ABR Industries booth and Chuck gave me (full disclosure–at no cost to me) a new product to test in the field: a 20 foot PL-259 to PL-259 assembly made with their ABR240-UF cable and with 5 in-line ferrites. What makes this cable unique is that it sports a bright orange flexible webbed jacketing which makes it very easy to see on the ground.

They’ve been informally calling it their “POTA cable.” I immediately knew why this would appeal to POTA ops: one of my constant fears is that someone will unknowingly trip on my feedline while I’m in the middle of an activation. Black coax cable on the ground is very difficult to see (I’ve even tripped on my own lines)–this high visibility jacketing makes cable very conspicuous. Just check out the photos above.

POTA Field Report: Pairing the Yaesu FT-817 and a 40M EFHW at Table Rock!

2 Comments

After a fun little activation of Lake James State Park (K-2723) on the morning of Monday, July 31, 2023, I decided to fit in at least one more POTA adventure on a mini rove.

The logical choice was Table Rock Fish Hatchery since it’s such a short drive from Lake James and I always enjoy activating that particular site.

The weather that morning was beautiful and so was the drive.

Table Rock Fish Hatchery (K-8012)

I pulled into the driveway of the picnic area and–no surprise here–I had the place to myself.

In fact, according to the POTA website, I’ve activated this site 12 times and I’ve never seen another soul in the picnic area save my canine friends, park staff, and one guy who was hunting muskrats in the creek. That’s about it. Never anyone actually hanging around the picnic area.

On the drive over, I hadn’t considered what antenna or radio to use–I had a few in the back of my car.

I thought about using my Elecraft KX1, but then realized I didn’t have an extra shielded audio cable to connect to my Anker Soundcore Mini speaker nor did I have my in-line digital audio recorder. Without those things, I wouldn’t be able to make a video of the activation.

My next choice was the Yaesu FT-817ND and, in fact, it would be ideal. I was looking forward to putting the ‘817 on the air again–it’d been a couple of months!

First, though, an antenna. I pulled out the 40 M End-Fed Half-Wave Steve (MW0SAW) made for me some time ago.

This antenna has been in heavy rotation lately because it’s been in my main radio backpack as I’ve been traveling around the region.

I deployed the EFHW in short order, then hooked it up to the ‘817. Continue reading POTA Field Report: Pairing the Yaesu FT-817 and a 40M EFHW at Table Rock! →

Survey #3 Results: What QRP HF transceiver would you or do you choose for air travel?

17 Comments

This past week, I posted the third of several surveys on QRPer.com, this time asking:

“What QRP HF transceiver would you or do you choose for air travel?”

I turned off the survey at 6:30 EDT today, with a total of 475 responses.

Survey Results

Here’s a pie chart showing the top 18 results in the survey. To see detail, you will need to click on the image below (or click this link) to enlarge it in a new window:

The top choice was the Elecraft KX2 which accounted for 22.9% of the votes.

It’s funny: I had assumed the Icom IC-705 might take first place in this survey. Then I realized that I own both the KX2 and IC-705 and, this summer, I chose the KX2 each time I traveled. Indeed, I can’t think of a time in recent memory that I didn’t take the KX2 with me during travels.

The reason I picked the KX2 each time is because it’s such a comprehensive HF radio with a superb built-in ATU and battery pack. There’s no field situation I can throw at it that it can’t handle. In fact, if a site doesn’t allow any antennas on the ground, I can even pair it with my AX1 or AX2 tabletop antennas.

I see why so many of you picked it as your first choice.

Your second choice was the Icom IC-705 which accounted for 14.3% of the votes.

The IC-705 has one very cool feature for travel: you can charge it with a common Micro USB charger!

No need to take a separate power supply, battery pack, or custom charger. Simply bring a Micro USB cable and plug it into the hotel USB charger, your phone’s charger, or even a Lithium power pack. If you’re happy with 5 watts of output power, you really need no other battery, power supply, or charger.

Of course, the IC-705 is compact, sports the entire HF band, VHF, and UHF and is multimode. It can also receive FM and AM broadcasts along with weather radio, and the AIR band.

You can even do D-Star natively and allow the GPS in the IC-705 to find the closest repeaters and load them to memory.

The IC-705 is a very savvy travel transceiver!

Your third choice was the Yaesu FT-817/818 which accounted for 9.9% of the votes.

At first, I was a little surprised the FT-817/818 would gather more votes than, say, the Elecraft KX3, but then again it’s actually a very compact radio. I remember when I used to travel Europe for a living, I would tuck my FT-817 into my carry-on and I hardly noticed it was there.

It also ships with a NiMH battery pack, and you can also buy a much longer-life and faster-charging Li-Ion pack.

The FT-817/818 is a rugged radio. You don’t have to worry about it being harmed in a pack and it lays pretty flat as well so it’s easy to protect and pad among your clothes.

The Elecraft KX3 took forth place with 8.6% of the votes.

The KX3 is one of the highest-performance field radios ever made and it is incredibly portable.

I added the Side KX panels to my KX3 many years ago. With those installed and using the Lexan cover, it’s a very rugged radio. Simply toss it on your flight bag and you’re good to go!

The KX3 is also a very efficient radio, so you could easily power it with, say, a $25 Talentcell USB battery pack–one that TSA wouldn’t blink at.

I’ve traveled pretty extensively with my KX3 so I see why it ranks so high on the list. Like its newer sibling, the KX2, it has an amazing internal ATU. You can also load the KX3 with AA cells for short on-the-air sessions or longer listening sessions.

Fifth on this list of travel radios is the Xiegu X6100 which accounted for 6.1% of the votes.

No doubt, what makes the X6100 so appealing is that, like the KX2, it’s a proper shack-in-a-box. Indeed, I would also add the X5105 to this same list.

The X6100 contains a high-capacity rechargeable internal battery pack and an excellent ATU. It’s an all-in-one radio solution that’s actually quite rugged and could easily handle the bumps and jolts of air travel.

Notable mention…

There was another winner in this survey. It wasn’t any one model, but rather a whole class of HF transceivers: super compact portable transceivers. If lumped together as a category, these would have placed in the top five.

I’m talking about radios like the: Mountain Topper series, QCX-Mini, QMX, QDX, SW-3B, (tr)uSDX, TR-25, TR-35, and similar. These radios are so incredibly tiny that they can be packed away in a very compact pouch.

Indeed, I have a complete dedicated POTA/SOTA station built around my Venus SW-3B (see photo above). It’s all contained in a small BROG headrest pouch that I could easily toss in a travel bag.

These pint-sized radios aren’t general coverage radios like the top 5 listed above, and many are CW-only. Still: if your goal is to hit the field a bit during your vacation, they’re incredibly effective.

This radio class also represents some of the most efficient and affordable transceivers on the market.

Survey #2 Results: If you could only have one QRP radio for all of your ham radio activities, which one would it be?

20 Comments

This past weekend, I posted the second of several surveys on QRPer.com asking:

“If you could only have one QRP radio for all of your ham radio activities, which one would it be?”

The responses started flowing in immediately and, once again, within the first day we had already accumulated over 400 votes.

I turned off the survey at 8:00 EDT on Tuesday, May 16, 2023, with a total of 618 responses. Due to my travel schedule this week, I didn’t leave the survey open for responses as long as I did for Survey #1.

Survey Results

Here’s a pie chart showing the top 14 results in the survey. To see detail, you will need to click on the image below (or click this link) to enlarge it in a new window:

The top choice was the Icom IC-705 which accounted for 28.8% of the 618 votes.

I’m not at all surprised the IC-705 was the most popular choice.

This survey focused on the one single QRP radio you’d pick to accommodate all of your ham radio activities, modes, etc. Frankly? The IC-705 does it all: HF/VHF/UHF multimode operation, DV voice (D-Star), built-in GPS, wireless connectivity for digital modes, built-in sound card, built-in Bluetooth and WiFi hotspot, built-in recording, broadcast band reception, high-performance receiver, color spectrum display and waterfall, and so much more. Heck, you can even charge its battery pack with a common Micro USB charger.  Read my review if you want a more comprehensive view of the IC-705.

The only real con anyone mentioned was a lack of an ATU which, frankly, is something that’s so easy to remedy with an external ATU or by using resonant antennas.

Your second choice was the Elecraft KX2 which accounted for 20.1% of the votes.

The KX2 is such a versatile portable HF transceiver that it was the most popular choice in our first QRP radio survey. No doubt, those who chose the KX2 love playing radio in the field as their primary activity because it’s such an adept and versatile radio to take outdoors.

Your third choice was the Elecraft KX3 with 18.7% of the votes.

I actually thought the KX3 would take second place since it’s one of the highest-performance HF radios on the market and covers 160-6 meters with a 2 meter option. It’s an HF Swiss Army Knife of a radio.

In fact, during the first day of voting, the KX3 held the number two spot with as much as a 2% lead over the KX2, but as more votes rolled in, that lead narrowed and the KX2 displaced the KX3 for runner-up.

Your fourth choice was the Yaesu FT-817/818 which accounted for 10.5% of the votes.

Again, I’m not surprised the FT-817/818 ranked high among survey respondents. As I mention in a recent article, the FT-817/818 is an amazingly versatile, durable, and capable QRP radio.

It’s also the most affordable among these top contenders!

Like the IC-705, the FT-817/818 has multimode capabilities from 160-6 meters, VHF, and UHF.  It also sports both SO-239 and BNC antenna ports which makes it very unique among QRP radios!

The lab599 Discovery TX-500 took fifth place with 3.9% of the votes among this set of distinguished radios.

Those who chose the TX-500 appreciate it for its 160-6 meter coverage, its unique form-factor and weight, overall performance, weather-proofing, and superb RX/TX current numbers for battery conservation. For those who like to play radio outdoors (sometimes in the rain) for hours at a time with a modest battery? Yeah, the TX-500 is made for that stuff!

If Yaesu designed an FT-818 replacement…what would you like to see?

71 Comments

We hams can be quite opinionated when it comes to our radios.

After Yaesu announced last week that it was discontinuing production of the FT-818ND, hams across the globe expressed their opinions about this pint-sized rig.

It seemed to me that the majority who posted messages in email groups and on social media had high praise for the FT-817/818. Indeed, many of those same people purchased an FT-818ND the same day of the announcement. The rush of FT-818ND purchases wiped out new inventory at most US retailers overnight.

Not everyone had praise for the FT-817/818 series, though. Many felt the ‘818 was a relic of the past and irrelevant in 2023. Some even posted long “good riddance” rants about the FT-818.

Let’s face it…

Our love of radios is highly subjective

What one person loves, someone else might hate. This is especially the case in the incredibly diverse ham radio world where radios are used in different parts of the spectrum, with different modes, for different activities, and in different operating environments.

The enduring Yaesu FT-817 and FT-818 series transceivers

54 Comments

The following article originally appeared in the October 2022 issue of The Spectrum Monitor magazine:

The enduring Yaesu FT-817 and FT-818 series transceivers

by Thomas (K4SWL)

Last April, our family went on a camping trip at New River State Park in Ashe County, North Carolina; we had an absolutely brilliant time.

Naturally, as with any camping trip or extended travel, I’d put a lot of thought into choosing the portable transceiver and field kit to take along.

The great thing about camping at a state park is that I can “activate” that park via the “Parks On The Air” (POTA) or “Worldwide Flora and Fauna” (WWFF) programs pretty much anytime: early morning, late afternoon, or even in a late shift well into the night. Or, of course, all of the above.  Since my activation site is also where I’m eating and sleeping, my radio usually gets heavy use.

Before leaving on that April camping trip, I knew what radio I wanted to operate the bulk of the time: my Yaesu FT-817ND. For a lot of reasons which  I’ll delve into later, I think the FT-817ND (or its latest iteration, the FT-818ND) is an amazing QRP field radio.

Despite unstable propagation and a little campground QRM that moved in over the weekend––no doubt from a neighboring RV, chock full of noisy switching power supplies––I found the FT-817ND activation to be a most enjoyable experience. I posted a few field reports and activation videos from my New River activations on QRPer.com. 

The thing is, each time I publish a field report using the FT-817ND, I receive a string of questions from subscribers and readers. Questions such as…

  • Should I buy a new FT-818 or a used FT-817?
  • Why do you like the FT-817ND so much?
  • What’s the difference between the 817 and 818?
  • How does the FT-817/818 compare with _____ radio?

Most queries, however, are a version of this comment from reader David:

“We have such a wide array of QRP rigs available to us these days, I’m curious what brings you back to the Yaesu for activations? It’s bigger than our more modern radios, with no ATU and more current draw.   I’m just wondering if there is something that you find it does particularly well, or if it’s just ‘because I like to use it,’ which to me is an entirely valid reason, too! My 897 served me well, as does my 891; I’ve had Yaesu handhelds forever, so I’m certainly a fan. I don’t own an 817/8 but they have a devoted following so I just wanted to get your perspective on it.”

Or as another subscriber distilled the question:

“Why choose a legacy design like the 817/818 when newer QRP transceivers have better overall field specs and features?”

Of course, these types of questions are simple enough when it comes to asking, but when it comes to answering, much more complex.

Of course, as I said in my recent TSM article about choosing a field radio, one’s love of a particular radio is by definition quite subjective, and this certainly applies to my response…we all have our own personal preferences.  But behind these preferences are objective facts, such as product’s unique features, specifications, and form factor; let’s take a look at these.

Ken’s photos comparing five field radios

Many thanks to Ken (WW5A) who writes:

Hello Thomas-

I enjoy reading the posts on the QRPer. The size comparison photos recently posted got me thinking. I had taken a photo several months back of a X5105, 817, RS918 (McHF), G90 and a 705, basically to do the same thing (size comparison).

I have attached them for your amusement [click to enlarge]:

73,

Ken WW5A

Thanks for sharing these, Ken. To me, it’s interesting to see the comparison between the FT-817 and the G90. When I owned a G90 I didn’t have an 817 at the time for comparison. It reminds me just how long/deep that G90 was! Also interesting to see that the mcHF clone is a wee bit wider than the IC-705. Thanks for sharing!

How to assemble a narrow CW filter for your Yaesu FT-817/FT-818/FT-857/FT-897 (an affordable YF-122C equivalent)

30 Comments

QRPer.com readers know that I’m a big fan of the venerable Yaesu FT-817 and FT-818 series transceiver.  So much so, I own two FT-817NDs–I purchased a second unit last year primarily for full duplex satellite work.

As I mentioned in a previous post, the one gotcha with the FT-817 and FT-818 is narrow CW filter availability. The YF-122C 500 Hz and YF-122CF 300 Hz Collins filter boards are no longer produced. Neither are the Inrad equivalents.

With the renaissance of CW we’re experiencing along with the growth of POTA, WWFF and SOTA, narrow CW filters for the FT-817/818 are very difficult to find and come at a premium when you do find them. I saw one sell recently for $250 US–over double what I paid two years ago.

In addition, this same filter not only fits the FT-817/818, but I believe it also fits the popular FT-857 and FT-897 series transceivers (please correct me if I’m wrong about this).

The Problem: I wanted another narrow CW filter

One of my FT-817NDs is loaded with a Collins 500 Hz mechanical filter that I purchased from my buddy Steve (WG0AT) nearly two years ago.

The second FT-817ND had a narrow Inrad 2 kHz SSB filter that came with the radio when I purchased it used (see image above).  Initially, I had no intention of buying yet another narrow CW filter because I’d only planned to use the second unit for FM and SSB satellite work.

Then, during field day this year, I decided it might be fun to build a quick-to-deploy portable HF station with something like an Armoloq TPA-817 pack frame. That thought experiment made me realize that I should simply bite the bullet and get a narrow CW filter for the second FT-817ND.

I started searching in late June and was simply not willing to pay the price for the very few filters that have shown up on the the used market.

The Solution? Assemble one!

I owe QRPer reader, Petr (OK1RP), for this tip.  Thank you, Petr!

The process of assembling your own narrow filter is actually quite simple and affordable. If you have even the most basic soldering skills, you’ll be able to manage this easy project. If interested, keep reading and I’ll show you how you can assemble your own…

Brent’s updated review of the CQHam TB Box

8 Comments

Many thanks to Brent (VA3YG) who writes:

Hi Thomas, hope you’re well.

Just a short message to bring you up to date on the performance of the new equipment.

In a nutshell, it’s brought me back to my old faithful friend, the FT-817. I bought my FT-817 20 years ago and it’s served me flawlessly all these years. It’s not the best at everything but it’s a perfect QRP shack-in-the-box.

The TB Box makes the little Yaesu a pleasure to use. The tuner tunes my 43’ vertical and K6ARK end fed random wire from 80-10 for the vertical and 40-10 for the ef random wire.

The battery tray slips out to reveal 6 Panasonic 18650 cells. The battery life is exceptional even with the 817 set on 5 watts. I’m just now in the process of topping the batteries up.

Attached are a couple pics of my operating situation today….it was such a nice day out on the driveway. I have a telescopic pole attached to the RV and strung the 41’ of wire up. Also, a closeup of the battery tray and one of the cells.

I can whole heartedly recommend this piece of gear to supplement an FT-817/FT-817ND/FT-818ND.

Loving it!

72/73,
Brent VA3YG

Very cool! Thank you for sharing the update, Brent! I’ll admit that I like the “old school” simplicity of this power and trans match system.
