A day early again!

I got confirmation from Elecraft on Monday that my K3 was shipping UPS 3 Day Select. So you have to figure – Tuesday, Wednesday, and delivery on Thursday.  In fact, that’s what the official UPS Tracking Website confirmed for me – delivery by the end of the day on June 28th.  So imagine my surprise when I got home to find a big brown box waiting for me.  Inside was:

Serial number 6625 – just waiting to be built!

Also included inside are the K3 ATU, the 400Hz, 8 Pole Roofing Filter, and the handheld microphone. I also ordered a microphone for the KX3 while I was at it.  And no, before anyone gets all excited, I am not renouncing CW!  I got the microphone(s) for two basic reasons.

1) Doing Ham Radio demos.  I have found that demos go best when you show folks CW and SSB.  There’s nothing like putting a mic into the hands of someone and allowing them to speak with someone halfway around the country, or the globe for that matter.  It’s something that THEY can relate to.  Morse Code is “cool” as I have been told by a lot of kids – but letting them talk to someone in far off Uzbekafgonalakistan is the ultimate “Wow”.  (A note to my lawyer – yes, that is a made up country name).

2) Special Event stations – I really used to like to hunt them.  A lot are not on CW at all these days, a lot are phone only.  Hence, my decision to buy some microphones.  Take for instance the “13 Colonies” Special Event that is held each year around Independence Day.  Last year I was able to find exactly ONE state (MA) on CW.  Maybe I won’t work many; but at least now I can try.

I really have to tip my hat to you SSB QRP guys.  You guys have supernatural patience!  Except for the rare instance, I will stick with CW for a 99% majority of my operating time.  I don’t have your kind of patience.

Tonight was preoccupied with other matters. Tomorrow night, God willing and the creek don’t rise, I will begin by doing a complete inventory.  I don’t expect anything to be missing as K3s are not rushing out the door as the same rate as KX3s.

Oh, and by the way, in case I didn’t mention it ….. the K2 is going NOWHERE!  I am NEVER giving that radio up!

Even though the sunspot number is a paltry 28, I had a good night on 20 and 30 Meters.  Germany, Lithuania, Ecuador and The Ukraine were all easily reached with 5 Watts. I even managed to bust a mini-pileup to work the Lithuanian on 30 Meters.  That felt really good!

Holy Hannah!

I looked at the weather forecast for the next two days – 96F tomorrow (35C) and 102F on Thursday (39C). Wow! I guess it is no coincidence that tomorrow is the first day of summer.

And wouldn’t you know it ?!?  Band conditions seem to be headed right into the toilet as Field Day weekend approaches.  The Sunspot number is 66 and declining. We’ll get to see of Amateurs create their “own” propagation this weekend.  Maybe with that much RF heating up the ionosphere, we won’t need so many Sunspots.

The past few nights have been very good on the bands.  Tonight, the noise floor seemed to be higher and it sounded like there was less activity.  FG5FR was booming into NJ from Guadeloupe; but I worked Frantz about a week ago, so it’s time to let other stations have at him.

Looks like some reading tonight and then sack time.

Here in the USA

we are celebrating Father’s Day tomorrow.  So from W2LJ to all my Ham friends around the world who are dads – Happy Father’s Day!

Being a dad has come a long way from what it was when I was a kid.  Not to say that my Dad wasn’t involved, he was.  But back in the day, Dad’s primary role was “The Provider”.  He put in his time at work and when he came home, Mom made sure we didn’t bug him too much!  He did his share of chores (yardwork and such) but Mom always made sure he got a chance to unwind and relax at the end of the day.

Today, I find myself way more involved with my kids, than my Dad was ever involved with me.  This IS NOT a complaint, as I wouldn’t have it any other way – but it can be exhausting, especially when a school project or a game or whatever comes up after a long, hard day at work.

But you know what? This is exactly what I signed up for when I said, “I do”.  My kids are the apples of my eye and I don’t ever want to go back to the life I had before they came.  Not to say that it was bad, as it wasn’t; but the two of them have made life so much better.

Getting back to radio, that double CME that was foretold by Spaceweather.com didn’t seem to really put any damper on the bands.  After a multitude of chores were completed, I got to relax at the end of the day down in the shack.  I worked David MI0VKO in Northern Ireland on 17 Meters and on 30 Meters,  had a very nice rag chew with Jeff, K8CQ who lives down on St. Simons Island, GA.  The KX3 continues to impress, especially its ability to really dig super weak signals out of the background.

I did something the other day with it that really surprised me.  And it was something very simple.  I plugged in ear buds instead of using the internal speaker.  Wow!  The difference was amazing.  I can only liken it to listening to a broadcast radio in the “old days” and switching from AM to FM. The change in fidelity and richness of the audio is remarkable.  I’ve never experienced this with any other rig, including my K1 and K2.  Eric and Wayne HAVE hit a home run here, and I’m tempted to say it was a Grand Slam.

Again, to all of you who are dads out there – Happy Father’s Day!  And of course, my prayers go out to all the Dads who have gone before us and can’t be with us tomorrow.

Getting in some operating time

tonight, because according to Ron WB3AAL and a post he made to the Polar Bear reflector, band conditions might turn into a mess this weekend:

Space Weather News for June 14, 2012
 http://spaceweather.com 

DOUBLE CME: Active sunspot AR1504 is facing Earth and hurling coronal mass ejections (CMEs) in our direction. A fast-moving CME that left the sun on June 14th is expected to scoop up another CME already en route and deliver a double-blow to Earth’s magnetic field on June 16th. Weak-to-moderate geomagnetic storms are possible when the clouds arrive. Check http://spaceweather.com for images and updates.

Tonight, band conditions are nice and I am having a blast.  I had a very brief QSO with TJ W0EA and this ended up being my first KX3 to KX3 QSO.  I am also hearing a lot of European stations and am able to work quite a few.  But this just goes to show you ………..

My QSO with TJ was very brief because my signal to him was exceptionally crappy.  I looked down and realized that I was still on the EDZ for our QSO.  After signing with him, I switched over to the Butternut, called CQ again and got a 559 from OM7DX in the Slovak Republic.

The other night was a first for me.  I heard my very first VU station – ever!  For whatever reason, I have never even heard a station from India before.  Hearing one the other night was an exciting first for me.

Ah, yes …. it’s Friday night, the work week is done, the weather is nice and I get to go on the radio.  Great way to start Father’s Day weekend!

Interesting night on 20 Meters

I kept the radio tuned to 20 Meters for the evening and had a variety of QSOs.

The first was with CO6RD, Reynaldo in Cuba.  This wasn’t a long QSO as Reynaldo was working “contest style” racking up the QSOs. But I did get him on the first shot, even though a lot of stations were calling.

Next up was a busted QSO with Mike AA6WQ, who was operating from TN.  We got through the QSO basics, only to have the band pull the rug out from under us.  One minute we were going at it, next minute we couldn’t hear each other anymore. I guess that’s the way the cookie crumbles, sometimes.

With two short QSOs under my belt, I was thinking that might be how the evening was going to go. But my fears turned to be for nothing as the next QSO was an almost hour long rag chew with Paul W4KLY in Stone Moutnain, GA.  This was an Elecraft to Elecraft QSO.  Paul was using his K1 and (of course) I was on the KX3.  QSB had a role to play; but in all honesty, when the band was not in fade mode,  our signals were 599 both ways.  We talked about rigs, portable ops and antennas and summer vacation plans.  It was very enjoyable and it is truly amazing to see how fast an hour can go by on you when you’re having fun.

The last QSO for the night was with Rumi LZ2RS in Bulgaria.  He was calling “CQ QRP” and I was lucky enough to be heard on my first call.  Rumi was at 5 Watts; but what really made the QSO was his Yagi at 12 meters up, pointed my way.  I was on the 88′ EDZ pumping out 5 Watts from my end also.  Signals were a legitimate 559.

The bands have been so good lately!  Not the best I’ve ever witnessed; but after the past few pitiful years, this is like Heaven (comparatively).  I sure hope it stays this way for a while and doesn’t take a fast dive off a cliff into oblivion.

On another note, this new 9 cell battery that I got for the Acer is fantastic!  I got it Monday and attached it to the netbook for charging.  I’ve used it Tuesday, Wednesday, and tonight – about two to three hours per night.  The indicator says it still has about another two hours left in it.  Of course, I have Windows set for “Max Battery Life” through the control panel, but even so, this is way outlasting the old battery.  That one gave me about two hours computer time, tops.  This battery should be able to get me through a four hour sprint (outdoors) without breaking a sweat.

Got 3 spare hours?

Want to see a KX3 build from start to finish?  TJ, W0EA treated us to live video on USTREAM while he built his:

http://www.ustream.tv/recorded/23127348

If you have a kit on order and have the time, I would really advise watching this (Hint: Start viewing at about the 8:00 minute mark).  Looking at stills (like I’ve posted) is one thing.  Watching the build being done before your very eyes (in real time) is just priceless.

Even though mine is built, I also learned a thing or two.  TJ mentioned that there was a Builder Advisory note that I hadn’t seen anywhere. It concerns the speaker grill and the distortion that can occur if it is installed.  I was experiencing that distortion; so as a result of listening to TJ, I took it out. The unit sounds much better now.

I still haven’t done the roofing filter alignment. maybe tomorrow night as I have been way busy.  But I have found some time to get in a QSO every day for the past few days.  I worked EM2012UA tonight, which is a special event station for the 2012 European Football Championships. Five watts to the Butternut vertical is still getting my signal heard worldwide.

By the way, conditions on 20 Meters were superb tonight.  The noise floor was about S1 and I heard so many European and Caribbean stations up and down the band – it was amazing (especially the fact that it was around 02:30 UTC – recently the band has been dead by then).  The fact that the sun spot number is 154 is a good thing.  Maybe Venus imparted some magic as she crossed the face of the sun yesterday?  Who knows?  If conditions like these keep up for a while, I think we’ll all be happy.

I am becoming more and more familiar with the radio and quite honestly, it isn’t as complicated as I initially thought it would be.  The controls are well labeled and are pretty intuitive and easy to get the hang of.

The bait’s been taken; but the hook hasn’t quite set yet, but this fishy really wants a K3 now.

I’ve been getting a lot of spam comments over the past week or so.  Been averaging about 20 a day since I took the Captcha code thingy off.  I apologize for keeping the comments on moderation; but if I didn’t I’d be overrun by spam.  So if you make a comment and don’t see it for a while, it’s nothing personal – just haven’t gotten to allowing them through.

The bands are dead but can a WSPR defibrillator get results

20m WSPR results
As most of you know the conditions on HF over the last week have been dismal at the best of times. Over the weekend I found 20m to be flat and 40m was just more or less local stuff. So Monday I thought it was time to give WSPR a go again. I set the output to 1 watt and gave 40, 30 and 20m's  a go. I was surprised that 20m was alive on WSPR. It was odd that I was unable to hear any CW on 20m's but using WSPR at one watt I was heard overseas.  My fan dipole in the attic is not really setup for 30m's but with the tuner in the K3 I
30m's was local only
am able to fool the rig to see a flat match. The SWR on the other side of the K3's tuner for 30m's is about 9:1 (according to my LP100A) so with one watt from the K3 and a 9:1 match what type of power is getting up to the antenna. With the help of this calculator I can enter my feed line type, power input, frequency and SWR this will get me a rough idea of the power at the antenna. So at 1 watt with an SWR of 9:1 using 30ft of  LMR-400 on 30m's the output at the antenna is around 892mW's of  raw power!! That raw power got me local responses on WSPR.  As for 40m's with one watt........it was more or less dead.

40m's was dead
