In praise of the FT817(ND) and QRP
FT817ND QRP transceiver |
I have owned an FT817 practically since it was first released in the UK back in 2000. The FT817ND was bought this spring as a second QRP rig along with a Z817 auto-ATU. The transceivers are mostly used at home. They are ideal for digital modes.
In my view, the FT817ND is the very best rig available. My FT817ND was just under 500 pounds for cash, brand new with 2 yrs warranty. The nearest rig (about 5 times larger!) was the FT7 10W radio which did not cover WARC bands, much of 10m , 6m, 2m or 70cm.
The FT817ND could be further improved in several ways but if 5W (or less) is all you need, then this is an excellent radio. The KX3 is no doubt a better radio but is far more expensive (here in the UK) and is less suited for home use in my view. For the price of one fully loaded KX3 you can buy two FT817ND’s in the UK.
If you have never owned an FT817ND you don’t know what you’ve been missing.
As a plug for QRP, going from 100W to 5W is about 2-3 S-points. So if 100W would have been 59 you’d still be 56 at least with 5W. What’s all the fuss about high power? I have worked THE WORLD on SSB with just 2.5W to simple wire antennas (no beams!).
My FT817’s have been used on VLF, LF and MF with home-brew transverters and on all HF and VHF bands working some impressive DX.
There is a myth that QRP is “hard”. Let me tell you that is rubbish. Sometimes power helps, but that is rare. Mostly QRP is just plain good fun – making the hobby all new again. The most I use these days is 5W, and more often far less. QRP is great fun.
Go for it!
Always keep twiddlin’ that dial
even when it seems like there’s nothing out there. You never know what might come up!
It’s a beautiful sunny day here in Central NJ, so as per my custom, I headed out to the Jeep, the KX3 and the Buddistick at lunchtime. From the get go, it seemed very disappointing. There wasn’t a whole heckuva a lot of DX activity. What I was hearing were stations I have worked before and you don’t want to keep pestering guys on the same bands, just to get a contact in the log.
I started calling CQ at the 20, 17 and 15 Meter QRP watering holes with no takers. I was slightly discouraged (Momma said there’d be days like this), and was ready to pack it in and head on back to my desk, slightly early. That’s when I decided to give 17 Meters just one extra twiddle before coming in.
Bam! There was TM70UTAH loud as all get out! This is a Special Event station, commemorating the 70th anniversary of the Allied landing at Utah Beach on D-Day in 1944. First call and they were in the books! I have to admit, I was so excited when I heard them that I had to send my call a few extra times as I fumbled it in my eagerness to work them. I did hear a confirmation of W2LJ come back to me and I was smiling ear to ear. Next, just a few KHz down, I heard SP3DOF calling “CQ DX”. One call and I was in Jerzy’s logbook.
Wow! A WWII Special Event station and a Polish DX station worked within a few minutes of each other – a red letter day as far as I’m concerned. And all this was after I was tempted to throw in the towel for the day. So it’s a good reminder (to myself included) to keep throwing that fishing line back into the water. You never know what’s going to land on the hook.
The funny thing is, that TM70UTAH wasn’t even mentioned in that ARRL article on D-Day Special Event stations that I posted from the ARRL just a few days ago. So in addition to TM70JUN, keep an ear open for TM70UTAH. I would like to work both of them!

FDIM and Dayton
Once again, I do not have the good fortune of being able to attend FDIM and Dayton. Attending FDIM is like, #1 on my wish list, but not this year and probably not next year, either. Joey’s Confirmation is this weekend and next year, Cara’s will be the same weekend. So maybe FDIM 2016? I can always hope!
But even though I’m not there, I do have the symposium running on a separate tab and I am listening, while working. http://www.ustream.tv/channel/g4gxl-test is the link, for those of you not in the know.
What I am listening to is mostly over my head. I’m not a technical wizard by any stretch of the imagination. Most of these guys making presentations are using transporters while I’m still rubbing two sticks together, trying to make fire. That said, it’s still fun to listen to. Craig Behrens NM4T gave a talk that I am actually able to follow and enjoy – same for Rev. Dobson’s talk on regenerative receivers earlier this morning. And right now there’s a fascinating talk being given about WWII POWs building clandestine radios by Dave Cripe NM0S. Man, I wish I were there!
All this talk of Arduinos has me curious. There’s a guy who comes to all the NJ Hamfests who sells beginner kits and I have that ARRL Birthday Month coupon kicking around – and they have a good book on Arduino experimenting, if I remember correctly. Intriguing (like I don’t have enough to do!).
This afternoon during lunch I had a cool QSO with Gary WA2JQZ who was operating the Marshall Spaceflight Center ARC station WA4NZD. Gary was using a Yaesu FT950 at 5 Watts to a dipole. He was a good 579 or louder here and I got a 559 in return. I had actually worked Gary a few weekends ago during QRPttF. So we talked about that among other things.
And I hope I’m not “talking out of school” here, or giving away state secrets, but Gary shared some information that I am going to pass on. Please listen for N4A later on this year, sometime towards the end of July. The Marshall Spaceflight Center ARC will be using that call to run a Special Event station honoring and commemorating Apollo 11 – which of course, landed on the Moon in July – July 20th, 1969 to be exact. I’m not sure when they will be on, but I am sure there will be announcements in all the usual places.
As a Baby Boomer, I was a huge manned spaceflight fan/geek. When I hear about something like this, I make every effort to work the space flight themed Special Event stations – even if it means picking up a microphone (ugh!)
Update – Congrats to TJ Campie, W0EA (fellow blogger) who won one of four TenTec Rebel radios, which were given as door prizes today at FDIM. It was neat to listen in as his name was announced.

Mental gyrations
Yesterday, the bands seemed a little on the “light side” when I headed out for lunch. Both 15 Meters and 17 Meters had some signals, but it seemed like most of the DX stations were ones I have already worked before. So I decided to go to the 20 Meter QRP watering hole and put out a CQ.
I was answered by Bob AK4JA in Georgia. He was a solid 589 at peaks and he gave me a similar signal report. Here’s the thing – while I was using my normal 5 Watts, Bob was running 500 mW! And his signal was fantastic! While I am fully aware how QRP signals don’t necessarily equate to “weak signals” – even I stand up and take notice when a QRPp signal almost pins my meter. I kind of felt like this guy – remember him from TV commercials a few years back?
For those readers not from the US, the Department of Energy ran a series of public service announcements a few years back asking people not to be “Energy Hogs”. Normally, running 5 Watts can make you feel smug with that regard. Yesterday, using even 5 Watts made me feel piggish.
For the record, Bob was using a Yaseu FT817 to a dipole – and it was doing a fantastic job for him. His 1/2 Watt signal almost sounded like he was transmitting from a location just down the street.
When I got home a “new” computer was waiting for me. I purchased a refurbished Dell Optiplex 320 from the Blair Group via eBay. This was the same place from which I had purchased a Compaq to replace the family computer which died a few weeks back. For a very good price (under $150), I got a Windows 7 box to replace my shack laptop, which is not only an XP machine, but is physically on its last legs after suffering through years of “kid abuse”. I figured that it’s better to replace it now, while the laptop is still barely kicking, so I can access all the data that is still there before it totally dies. As it was, I was already using an auxiliary keyboard and monitor, so I only had to purchase the box.
So I ran through the Windows 7 setup with nary a hitch. But then, of course, comes the fun part. Getting all the important Amateur Radio programs up and running. I downloaded Log4OM and got that running. I followed the directions for transferring all my log data and configurations from the XP machine to the Windows 7 machine. Everything seemed to be OK – except the program wasn’t displaying any of my previous QSOs! Log4OM said they were all there, but it just wasn’t showing them in a visible way. It turns out that the W2LJ.sql database file needed to be in a different sub-directory than where it was located on the XP machine. Once I got that figured out, things were good. But for a while there, the little beads of sweat started popping out on my forehead while I started muttering to myself, “Where are all my QSOs?”
The next problem to tackle was downloading the KX3 and KXPA100 utility programs from Elecraft in order to get them running, as well as OmniRig for CAT control for Log4OM. Downloading and installing the programs was easy enough – the computer did all the work while I tuned around 20 Meters. The hard part was figuring out why the computer didn’t want to talk to the KX3 or the KXPA100.
For whatever reason, it didn’t turn out to be as “plug and play” as it sometimes is. Every time I tried to get the KX3 utility to talk to the KX3 – nada, zip, zilch. The radio and computer were acting like a husband and wife after a marital spat – not talking to each other. It appears that the KX3 was looking to talk via Com1 – but that was being used by another device. And when I hit the “Scan for Ports” button on the utility, that was all that I was getting.
That caused me to make a sharp right turn and head off to the dreaded Control Panel and even more dreaded Device Manager. For those of us who don’t consider ourselves to be all that computer savvy, this is dreaded territory. Kind of like walking through the Valley of the Shadow of Death.
But it was there that I was able to scan for hardware changes, open another port (Com 3) and load the drivers for the Elecraft KXUSB cable. After that, the KX3 and Log4OM and the utility programs and the Dell were all smoochy-smoochy like a newlywed couple.
Satisfied that I got the very basics covered, I looked up at the clock to discover that it was after Midnight. Holy cow! When you get up before 6:00 AM, post Midnight is late – very late! I still have to download and install Avast (one of the first things I did was to uninstall and trash Microsoft Security Essentials, which IMHO is useless). After that, there are a few more remaining Amateur Radio programs that I have to re-download and get running – like DX Atlas for instance. Then I need to transfer accumulated documents and photos from the laptop and then I can finally say “Good-Bye” to Windows XP.
And that, in itself is kind of sad, as I consider XP to be the most stable and useful platforms that Microsoft has ever come up with. If it wasn’t for the fact that my laptop looks like Rocky Balboa after a tussle in the ring with Apollo Creed, I probably would have kept it going for a while longer. However, time marches on and I suppose it’s appropriate to modify that well known saying – “Time and Microsoft wait for no man”.

Warm!
The weather has taken a decidedly summer-like turn in central NJ. At lunch time today, the outside temperature is a June/July like 84F (29C). You will not hear a word of complaint out of me, that this is too hot, considering how long and extended our winter was. I’ll take this any day of the week!
As the situation at work returned to somewhat normal, I was able to head out to the Jeep this afternoon, for my hour long break. I was able to work out of the back, with the rear tailgate open, providing a bit of shade from the Noon sun.
15 Meters and 17 Meters seemed to be the active bands. On 15 Meters, I worked SN777AG – Jurek SP2GUB who was commemorating the 777th Anniversary of the City of Elblag, which is not far from Gdansk.
After SN777AG, I worked Jose EA1MX in Spain. QSB got the better of that QSO. We were able to exchange rudimentary RST information, and that was about it. I’ll count it as complete QSO, but I hate when QSB kills an opportunity for more.
I then hopped on over to 17 Meters, where I worked EM90WF in the Ukraine, another Special Event Station. This one was to commemorate the 90th birthday of Vladimir Goncharsky U5WF (SK). Vladimir was not only a very successful Ham who had won many awards, but was also a WWII veteran. The station was loud into NJ – very loud. This is not the first time I have heard them, or have tried to work them, as I’m always attracted to very loud signals from DX stations. Attempts to work EM90WF in the past were unsuccessful. In fact, a few weeks ago, I spent one or two lunchtime sessions trying to break the pileup, fruitlessly. Today? First call – go figure.

KX3 Heat Sink
If you operate your Elecraft KX3 in a portable environment (and perhaps even if you don’t) there are a few must-have add-ons which really help protect your KX3. You are probably already aware of the popular KX3 KX Endplates and KX Cover available from Scott, AK6Q and his Gems Products website. I received both as a Christmas present from my darling wife and love what they do for my KX3.
In addition to operating SSB phone via my KX3 on SOTA activations, I also enjoy grabbing my Buddipole a battery and heading outdoors for some picnic table portable operations in a park or really just about anywhere. In this setting I typically bring along my laptop and operate PSK-31 or JT-65. However, one thing I’ve noticed (and have been concerned about) is how the KX3 has the potential to heat up when running these digital modes (even at 5w or less). This is especially evident in the warmer months of the year.
A few weeks ago I was browsing the KX3 Facebook page and learned about an add-on heat sink designed, built and sold by a fellow ham in Canada. This OM’s name is Fred Meier, VE7fmn. I contacted Fred via email and he quickly provided a detailed response on how he designed his KX3 heat sink and provided cost and availability information. While I did find one other heat sink being marketed for the KX3, I believe Fred’s version is more effective at dissipating the heat from the KX3 and it looks great while doing it.
Here’s what Fred’s KX3 heat sink looks like installed on my KX3.
Fred’s KX3 heat sink is well built and designed to be durable. The fins on the heat sink are not going to bend or break off and only adds an additional 8 ounces of weight to the KX3.
I’ve conducted a few tests while in the shack and had the KX3 running PSK-31 and JT-65 at 10w and never received the overheat warning. I couldn’t run above 5 watts inside or outside the shack without the heat sink installed. I’ve yet to test the KX3 with heat sink installed outside in a portable setting, but I’m confident I will not have any issues. If you would care to read another review of VE7fmn’s heat sink, please go here.
As I’ve stated, I love operating portable with my KX3 and I’m Happy, Happy, Happy to have this wonderful add-on to help keep my KX3 Cool, Cool, Cool.
Until next time…
73,
Jerry
Cut short
Every now and then, my lunch time QRP sessions are cut short by a work crisis. Such was the case today. Not hearing many strong signals during my initial tune through, I decided to call CQ for a while and then go back to search and pounce. I managed to call CQ alright, but never got to the search and pounce portion of the plan. My cell phone buzzed in my pocket and demanded a quick return to my desk to handle “a situation”.
The bright side is that my CQs, although unanswered, were at least heard:
