Good lunchtime DX session

When I left the house this morning for work, it was all of 52F (11C), which is very cool for New Jersey this time of year.  Also, I noticed on the drive in that many of the trees already have leaves that are turning yellow and orange, and many trees have started dropping their leaves. Again, that is something we are accustomed to seeing at the end of September, not August.

But the day heated up, and by lunchtime it was 84F (29C). Quite a warm up!  And fortunately, it wasn't only the air temperature that had gotten hot. 17 and 15 Meters were hopping and hot - well, maybe not as hot as a few months ago, but hotter than just a few weeks ago. The sunspot number had risen to 128 making conditions better than they have been in days. I'll take it!

I worked 9Y4/AI5P on Trinidad/Tobago, RI4CWC/3 in Russia and PI4DX in the Netherlands, all on 17 Meters.  The thought then occurred to me that if 17 Meters was working so well, then 15 Meters might be worth looking at.  It was, and after switching over, I worked OQ4U in Belgium and SP2GUB in Poland.  All the stations on both bands had excellent signal strengths and I got decent reports back, the lowest being 559.

I don't know how long these good band conditions will be able to maintain themselves. The way the Sun is throwing fits and starts, it may not be for that long.  But if you get a chance, get on the air and make hay while the opportunity presents itself!

KX3 troubles


A happy looking KX3
I decided to take the KX3 out and about on my day off Friday, it was an overcast day so I thought it wise to do my operating from the mobile rather than taking the bike. I set up the mobile whip antenna on my car and situated myself in the passenger seat and was ready to go.(note….this time before the trip out I made a list of things to bring so I was not without important items as happened in the past)  Brought the KX3 up to the 20m QRP watering hole (14.060) and just wanted to check the SWR on the radio before sending out my 5 watts of raw power. The KX3 gave me an error message but it seemed I was still able to transmit and I did for a short time. Then I noticed as I moved up and down the band my
Not so happy KX3
SWR stayed the same at 1.4:1 no matter where I was on the band….even up into the SSB portion. It was then determined something was wrong and I had a fast look at the antenna and coax but all seemed ok. I then switched to my 15m whip antenna and the error message was gone but I still had this strange low SWR across the 15m band as well. So it was time to pack things up and head home. Once at home I put the KX3 on a dummy load and tried it out and all was just the way it should be. I then put the rig on the MFJ 1788 loop and again no problems. So I suspect it's the mobile setup and I did post the problem on the Elecraft reflector and was given advice to check the mobile setup. When at home I did want to give the KX3 the full workout and to do so I started to call CQ on 20m. Terry WA0ITP came back to me from Iowa and our signals were in around 339 and conditions wee not that great but we were able to carry on a decent QSO. So the KX3 is working good but it's just another "project" I have on the burner that has to be worked out.  No time today as I am on call  this week and the phone has not stopped ringing with calls for me to go in!

2014 NJQRP Skeeter Hunt

First off, I don’t know who was hunting who. I thought I was hunting Skeeters, but I think they had other ideas – and I was the hunted:

And that was nothing compared to my legs! I didn’t think the little buggers would be so active during the day, so I didn’t bring my OFF wipes with me. I’ll remember this for next year!

I set up in my favorite park here in South Plainfield – Cotton Street Park.  There are plenty of 50 – 60 foot trees which just beg to have wire strung through them. It’s a quiet park and there’s not the overwhelming amount of traffic that Spring Lake Park (our Field Day site) gets. There were people walking through and playing, but no one came over to investigate what I was doing. I guess I’ve become a fixture – “Hey, it’s that crazy guy with the radio again!”

Off to the right, you can see the coax going up , up , up.  Here’s a better shot:

Today, I ended up using the PAR END FEDZ. I stayed on 20 and 40 Meters only, so it turned out to be the ideal antenna for the event.  The antenna launcher worked flawlessly again, and I would dare say that the end of the wire was up at the 60-65 foot level.  I don’t know if it was just me, but there was bad QSB and it seemed like one second, a station would be 599 and ESP the next second. As far as stations worked per band,  I ended up with almost a 50/50 split between 20 and 40 Meters. I listened briefly on 15 Meters, but it seemed like it was dead.

The equipment was the usual, but you might take notice of the new paddles. That’s a set of Pico Palm paddles that I recently bought from Rick K7MW.  The magnets hold the paddles securely to the Velamints tin that I use to store my earbuds.  They worked flawlessly!  If there were any CW mistakes (and there were) it was my fault, not the paddles.  They feel and work just as nicely as any full sized set of paddles.

I ended up working 41 different stations. 35 Skeeters, 6 Non- Skeeters, no DX, 19 different S/P/Cs, and I did work enough stations to spell out “SKEETER” for the 100 point bonus.  I ended up with 5,876 points. The loudest stations I heard were K3LRR, KX9X, N0SS and WA0ITP.  I worked my bud, Bob W3BBO and he was about 569. Later in the day, I heard him again on the same band, this time working WB3T. Bob’s signal had increased to an honest 589/599.  Tha bands seemed a little crazy today.

I’d like to thank not only the stations I worked, but ALL of you who participated.  This is so much fun for me – not only the event itself, but the planning and the corresponding back and forth with all of you. You guys really make this event worthwhile. My mailbox is already filling up with log summaries and I will work on those during the coming evenings.

There WILL be a Skeeter Hunt in 2015!  Hey, what better way is there to spend a beautiful Summer day than by being outside with your radio, making contacts with all your friends?

Replacement rechargeable battery for Elecraft KX3

Tracer Battery kit
In a recent post I told the blog world about the failure of my KX3 portable power source. It was an external battery that was ordered from China. The battery  lasted under a year until it just failed to take a charge. The battery was only used maybe 6 times.  Not sure what failed but a fellow blogger  Larry W2LJ with the same battery had a similar failure as well.  It was time to get on the net and look for another external, compact and reliable battery. Plan number one was to avoid the products from China as I have learned a hard lesson there! Reading blogs of op's who operate portable and use an external power source (when the internal batteries give up the ghost) I came across a company called Tracer operating out of the U.S. To make a long story short I ordered from them and below are the spec's on the Lithium Polymer battery.
Closer look at the battery
- 12 volt  8Ah, weight is 600 grams (19.4 oz), charge time is 8-12 hours and carry case.
- Come with it's own wall charger and car adapter charger.  
- An LED battery charge status indicator. 
- A flate discharge curve. 
- Zero self discharge. 
- A tough ABS case

Overpriced KX3 options

Steve G1KQH has spotted the price of “after-market” mics on eBay.  Under £5.

“The price of a Microphone:

Someone is having a good laugh at stitching folk up with those KX3 Mics.  The whole KX3 price is through the roof but there are plenty on the bands?”
I stand by my assertion that, sadly, the KX3 is overpriced, certainly over here in the UK. I know that it is a truly exceptional radio with a first class specification but, as I have said before, for my sort of operating – mainly from home and occasionally /P, the FT817ND is FAR better value and it covers 432MHz all modes too. I cannot fault the FT817 although I appreciate the KX3 is better on RX. My FT817 has worked the world on SSB and always with simple wire antennas. I have worked a lot of continents with whips on the rig indoors too.

Some operating time in the park.

The setup in the car
It was a great day today even though they called for rain  it was just overcast and very nice cool temps in around 17C. I was off work today and after I had completed the chores around the house it was time to get out in the outdoors for some ham radio. Since there was a chance of rain I decided to not set up outside and get rained out but instead I took my car and set up the Elecraft KX3 mobile from one of our near by parks on lake Ontario. I set out on my way and checked and double check all my items (last weekend I forgot   a coax connector and the portable op's came to a fast end) I arrived at the park around 13:00 local time and began to call CQ 20m I had no takers and decided to spin the dial to see who I could find. I did come across some DX stations calling CQ but was not able to be heard and some had very long waiting lists wanting to contact them. I then came across Bernie KB4JB from Florida and we had a very nice 20 minute QSO. The CW speed was in around 14 WPM and both of us were able to share station, location and other information before conditions changed and we both faded out. The KX3
20m mobile whip 
operated just fine for over an hour and a half on the internal batteries at 5 watts output. At one point during my QSO with Bernie for some reason my KX3 key was just not sending what I wanted. As time passed in our QSO I noticed my headphone cord was under the KX3 Key and causing the troubles. Once that was dealt with the code improved minus the headphone cord! I only made one QSO for the outing but it was a long one and the speed was at a very comfortable.  The antenna was a mono band 20m whip, the power was 5 watts from the internal rechargeable batteries and the radio as was mentioned the Elecraft KX3. It was time to head home and get dinner going for Julie's home coming from work.

KX3 antenna failure

I read on the M1KTA blog that an antenna lead on one of his Elecraft KX3 units has failed. I know these have seen some harsh portable field use but I would not have expected this.  I have owned an FT817 for close on 14 years and, touch wood, it has never once failed me – still the same PA, same everything.

In my view, the KX3 is overpriced (over here in the UK) and not well built for rugged field use. I don’t doubt it has excellent features and an excellent receiver, but it is still over twice as much as an FT817ND which covers DC to blue light, out of the box ready built. The KX3 is a mess for leads, coming out all over the place. The FT817 is neat, rugged, and compact.

For me, the FT817 still wins.
