This appeared on the KX3 YahooGroup reflector today:

All-

Attached is a photo of KX3 #6. It’s an outdoor shot with the backlight off. This unit is in Field Test here, which is its own type of milestone for all those waiting patiently. I’ll be writing objective appraisals of this FT unit. That will be my intent, anyway (objectivity). This email is a first cut. Read on.

My personal opinion is that this is the coolest amateur transceiver ever designed, built, or dreamed of. Perfect size, perfect weight, VERY respectable performance. You can *really* take the KX3 with you, and you’ll really want to. Mine’s going everywhere with me, including the workplace! I know my engineering staff will demand to see how Wayne and crew fit it all in, and how well the KX3 works.

After one day using this unit, I’ve reached the conclusion that the KX3 is basically ready for initial production. As is usual for a ‘young’ rig from Elecraft, firmware is still a work in progress. This should be no surprise to anyone on this list. The hardware is at near-100% shape, IMHO. There are a few minor issues – mostly features not yet implemented. And I mean minor. If I weren’t an engineering manager in the consumer products industry I would not have noticed any of them. The electronics seems solid, and I’ve done a bit of lab testing for MDS and selectivity. Most of my testing has been on the air though. My lab testing shows MDS better than -136 dBm, but my signal generator can’t extend any lower. No problems with rejecting out of band signals (away from the roofing filter’s coverage).

On the air: I’ve had about fifteen CW QSOs, using between 1 and 12 Watts output power. The antenna is a homebrew multi-band vertical, ground mounted. Four of these Qs were on battery power. No differences were found between operating on external and internal power, except for the output power limitations due to batteries. One Q was with an extremely weak QRP station in New Mexico. The APF helped with this, to the point that I could not have pulled him out without the feature. With APF engaged, his signal was 539 with rapid fades to 319. He was running 0.5W and I was running 3 W. Great ragchew, with very few repeats.

Except for Navy-Marine Corps MARS, I’m mostly a CW op. Several SSB contacts went successfully after a false start: I had to finagle the MH3’s input connection a bit (a virgin socket seating issue). I set the MIC and CMP values by listening on a second receiver and built in MONitor, giving MIC=18 and CMP=10 as the best combination. Audio reports using the MH3 and this setting were excellent – “clear as a bell” and “good presence”. Output using the internal speaker is adequate, though not amazingly loud. Some of that is probably my 55 year old ears and too many rock concerts when I was younger. The frequency response seems relatively flat and lows are surprisingly well-represented. Distortion is low (< 2% THD the way I hear it).

The FOC and NA contests run this weekend were an interesting environment for first-time ops on the KX3. Lots of strong signals, many in excess of S9+25. A majority of the QSOs mentioned above were near strong signals and with the roofing filter in place I had pretty good luck ignoring the big guns while working weak signals. I have to admit this is completely subjective, however years of experience with the K3 also tells me that the KX3 has similar characteristics in this regard. The best example from on-air testing was the NM CW station I mentioned above. His signal was marginal, meaning the APF was essential for pulling him out of the band noise. At the same time, 3 to 4 KHz up was one of those big guns thumping away. I could even hear key clicks from the contester, but only a tiny amount of blocking from his signal on the KX3. That’s what I mean by “similar to the K3”. It’s not identical though. I found instances where a little bit of a strong station’s signal was near- or in-band, and as you would expect some pretty severe blocking occurred. I’d recommend everyone make sure they have the roofing filter on the “essentials” list for purchase. In many ways the roofer makes the KX3 what it was meant to be.

One thing that’s notable and exceptional: I haven’t seen any of the typical issues of a “zero IF” architecture. No image problems, no ripple in the passband (in either SSB or CW), no audio artifacts. The advantage to a zero IF architecture is that there’s no “donut hole” around the IF frequency; there are others too – one single conversion takes less space than multiple conversions, less power consumed, less heat generated.

As a Navy-Marine Corps MARS operator, I’m looking forward to using the KX3 in our ECOM exercises. Its size and power consumption are perfect for such types of portable operation. It’s the item that will take the least amount of space in your Go Kit.

Sorry so much of this is non-quantitative. I’ll try to get more out after another day or two.

QRP – When you care to send the very least!

Now this is REALLY Freeze Your Buns Off / Polar Bear Moonlight Madness !!!

QRP’ers – are we dedicated or just plain crazy?

Gatineau Park and the Wolf Trail sure look beautiful!  Thanks Martin, for sharing, you have shown us the quintessential FYBO / PBMME effort.

FYI, the HK0NA DXpedition ended today.  Thanks to the crew and its supporters for their efforts.  I got them exactly once and that’s plenty for me.  According to the Team, even after 190,000 +++ QSOs, the pileups were still very deep.  Hope all of you were lucky enough to have worked them, if you were trying.

QRP – When you care to send the very least!

OK, I know…. This isn’t a steals and deals kind of blog, but I wanted to share with you a great promotion Amazon is running on the Elenco Snap Circuits SC-300.

I paid over $60 when I bought one for my kids a year ago and it’s on sale right now at Amazon for just over $30 with free shipping. If you have kids or grandkids who are interested in electronics and science experimentation, this kit can’t be beat. Do a little early Christmas or birthday present shopping and get them something they’ll really enjoy — and learn something from, too! You’ll be truly amazed at the projects they can create with this kit.

 OK, here’s the best part! If you buy it through this link, you’ll be helping to support one of my favorite podcasts, Jerry Taylor’s Practical Amateur Radio Podcast. Jerry does a tremendous job and there are many costs associated with creating and distributing a podcast. Buy a fantastic product (the Snap Circuits SC-300) for a special youngster and support a great cause (KD0BIK’s Practical Amateur Radio Podcast). It doesn’t cost you anything to use the link, but he’ll make a dollar or so to help support his podcasting efforts. Win-win!

And lastly, being from New England… GO PATS!

Yesterday a packet from the USA dropped on to the doormat. It was the LCD UI module from Gadget Gangster. The cheap international shipping option is pretty quick!

LCD UI module ready for assembly

On opening the envelope I was taken by surprise as I hadn’t realized the module was a kit. But there aren’t too many components and they are all through-hole so I should be able to manage it. I will take my time and double check everything to ensure I don’t do anything stupid like solder headers on the wrong side of the board. More than a few K2 builders have done that!

The instructions on the Gadget Gangster website are very comprehensive with several colour photos showing different stages of assembly. But on checking the parts against the parts list I found that I was missing one 2×8-pin header socket. Fortunately I found one (a pack of 2 actually) for a couple of quid from a UK based eBay component supplier so I should have it in a couple of days. eBay is my main source of electronic components these days as the usual sources like Farnell or Maplin all have hefty minimum order and postage charges that make ordering the single part you need to complete a project quite uneconomic.

Kits and Parts Universal RF Amplifier

 A few days earlier I received another kit from the USA: a QRP RF amplifier from Kits and Parts. I got this with the idea of using it with my Propeller beacon but it is probably too good for that. The beacon really needs only a simple class C amplifier to raise its output to a couple of hundred milliwatts. I had been tempted to go for a couple of watts but whilst WSPRing on 20m today and monitoring the signal on the K2 I noticed a weak in-band spurious around 14.05 MHz which no low-pass filter will eliminate. So it is probably best to stick to QRPp if using the Propeller as an RF source.

Another new arrival in the G4ILO shack was a GPS module from Hong Kong. This was used, ex-equipment, and cost about £12 including postage. I’m not sure what I am going to use it for but if I don’t put it in the beacon to provide a time reference (and locator) for WSPR it would be interesting to try to make an APRS tracker using the Propeller chip.

So many projects! But I am convinced that having this amateur radio hobby to give me so many different and interesting activities is the reason I remain cheerful and positive unlike so many people who have the same health condition and seem to fall into a slough of despond and hopelessness. I may never complete them but at least they give me something to stop me dwelling on darker thoughts.

FYBO was fun today.  No big effort as there were way too many other things going on that vied for my attention.  In between chores and duties, I was able to get out to the driveway, where I had the PFR3A on a battery in the back of my Jeep.  The antenna was the Buddistick on the magmount on the top of the roof.  Kudos to Bob W3BBO for suggesting this setup – it worked great!  The car body acts as a much better counterpoise/ground plane than the single wire and using the magmount eliminates the need for mast and guying.  So if you’re not hiking – this is a great way to use a Buddistick.

It ends up being much taller than a standard Hamstick (definitely not drivable), but the SWR was very nice and I was able to use the PFR3As internal tuner to even get that ironed out flat.

First QSO of the day was with Hank N8XX operating as “Amigo” with the WQ8RP callsign.  In all, I made 11 contacts in between grocery shopping, baking some bread for my daughter’s choir bake sale, etc, etc, etc.

Here’s a better look at the antenna.

On 40 Meters, I undid the tap and extended the whip all the way.  That gave me about a 1.4:1 SWR.  I only made one contact on 40 Meters and that was with Mark NK8Q in Pennsylvania.  He was using only 1 Watt and almost blew the ear buds out of my ears.  I don’t think I have ever heard 1 Watt as a 599 Plus before today.

The temperature was 45F when I started, so for simplicity sake, I used that throughout, even though I think it started dropping for my last couple of QSOs.  I think the lowest temperature that was reported to me was 32F and the highest was 76F.

QRP – When you care to send the very least!

As a pastor the months of December-January are the busiest of the year for me, so I haven’t done much with Ham Radio for weeks now. That is as it should be. As I’ve said before, we must keep our hobby in its proper place. But I haven’t let it completely die, and the hopper has slowly been filling up with things to share with you.

One of those things is the ARRL’s online/mentored course, “Introduction to Emergency Communication.” I’ve registered for the next session of this course which begins on February 29 and runs through April 27. It cost me $50 as an ARRL member ($85 for non-members), but I think it’s worth the money in my situation.

Not that I have to go through this course to learn the material. Much of the material may well be common-sense or a review of what I already know after being a ham for so long. The rest I could pick up by simply reading this book or (probably better) this book. Or I could glean it all from the web or learn it from an experienced member of ARES. So why would it be worth $50 for me to go through a formal course of study?

The answer: for credibility with governmental agencies.

Like it or not, to gain respect from governmental agencies you need to prove that you’ve jumped through a few hoops — especially in a state like Minnesota. Several decades ago Minnesota figured out how important it is to train police officers well. As a former police trainer myself, I cringe when I see poorly-trained officers on COPS. Trust me — agencies that have invested in training are rarely interested in “help” from poorly-trained people, no matter how well intentioned.

So before we go to the local sheriff (who is in charge of emergency management for our county) and talk to him about ARES, we need to get our ducks in a row. Training is #1 — and to governmental workers, that means certification of some kind. Be ready to show Show them paperwork. Other things help too, like uniform vests, jackets, etc., but those things come second. (In fact, you can shoot yourself in the foot with that stuff if you aren’t careful. Take it from me — as a former police officer I know what I’m talking about — if you overdo “the look” in your uniform, your amber light bars, etc. most cops will write you off as a wanna-be commando kid to be kept far away from the grown-ups. If you really want to impress them, wear a tie. Seriously!)

Furthermore, for certification to mean anything to governmental workers it needs to come from the biggest, most widely recognized institutions you can find. For ARES, that means FEMA and the ARRL. I know some hams don’t like the ARRL, and I may get pelted with comments about how terrible the ARRL is. But there it stands.

In order to register for this course you must first complete two free online courses offered by FEMA: IS-100.b, “Introduction to the Incident Command System (ICS 100)” and IS-700.A, “National Incident Management System (NIMS), An Introduction”. Whether or not you take ARRL’s course, you really ought to take these courses (especially the first one) if you ever want to participate in emergency services. I for one needed to brush-up on these things, and I appreciated how well they were done.

Once you successfully complete these online courses from FEMA (they don’t take long) you may register for the ARRL course on the ARRL website. Registration closes on Wednesday, February 15 for the session I’m enrolled in, and on Wednesday, March 15 for the session that begins on March 28. There is still plenty of room in my session — of the 30 seats available, only 21 have been taken as I write this on February 4.

The difference!!!

I purchased 2 Baofeng UV-3R Mark II handhelds with some accessoiries from Hong Kong. Unfortenately I had some bad luck with the package as my package got in sight at the customs. Apparently they didn’t believe the customs declaration that it hold toys worth 10 USD. So I had to pay an extra 19% VAT and 12,50 euro adinistration costs. Never happened to anyone but me of course. Anyway, I ordered 2 with profit so after all they are still cheap.  Lots of things have been written about this mini handheld TRX, that’s the nice thing about it. Actually the main advantage and why I bought it is the radio receive capability. You can listen  to the radio and once there is activity on one of the UHF/VHF frequencies it will switch over and back again  to radio when things are quiet. It’s extremely small so I had my doubts when unpacking. But I had the opportunity to have a experience with it as I had a small job to do 45km away from here today. Driving to the job I heard PD1B in QSO with PD/CT2FZY on the coversity network, nice conversation good receive. But it was busy on the road and a little slippery here and there because of the cold weather, so I kept my eyes on the road. On the way back I made a QSO with PD5GVP Gerrie who was also mobile and I noticed that the little Baofeng didn’t get as hot as my Alinco, great advantage. After the QSO I was called by PD2VB Bram who I know I think about 25 years, also a ex-CB operator. Bram does a lot of portable work himself like he already did years ago with a CB walky talky. He told me he had already been active iceskating portable! I could talk to him via the coversity network till I was at home, I didn’expect that from the little Baofeng inside the car! Nearest access point to the network about 10-15km away! So, I think this will be my little radio I always have with me in the future. It’s easy to fit in the pocket and even smaller then todays mobile phone! Some interesting links and info for future reference can be found on the website of PA2OLD Ben. I would recommend the UV-3R yahoogroup for the latest info about this little UHF/VHF mini handheld.

When I came home this afternoon I did a quick lunch. We brought Anneli to her bed for her afternoon nap. My XYL had to go for some shopping. So, I quickly did some necessary household things and after that up to the shack to listen for HK0NA. And yes after 15-20 minutes I finally managed a QSO on 15m SSB. Another new DXCC and I’m a happy operator. Working a new DX is one of my favourites, and when I read for instance the blog of EI2KC who works a new DXCC daily I sometimes get frustrated. I haven’t got  that much time to be active with my 45 hours a week job, family and things in and around the house. But then I think, hey there are other things in live besides radio. I already achieved so much with my hobby, be satisfied! Now next thing would be the PACC 2012, get ready…..6 days to go!
