A great day for portable op’s.

View from the portable op's position. 
It was another amazing day weather wise up this way and with winter soon coming I wanted to hit the trail again with the KX3. I was up and out around 10 am local time and off to search out on my bike a nice spot on the lake to operate. (Lake Ontario) The spot I found was right at the lake and I could see the police boats setting up their perimeter for the air show that would be happening around noon. I planned to be done my portable op's before the air show starts, the noise of the low flying jets (which is a very cool sound by the way) drowns out my CW coping skills. I set my endfed antenna in a sloper configuration as I found the inverted V was just not doing the trick. The CW open contest was in full swing and that sure was a bonus for making contacts. I checkout the Contest rules and they were looking for a serial number and name. I was able to make 8 contacts in the contest:
N4OX on 20m from FL
AF4RK on 20m from FL
K5WK on 20m from MS
N6ER on 20m from CA
KZ5D on 20m from LA
N5XZ on 20m from TX
W9ILY on 40m from IL
AA3B on 40m from PA
N8BJQ on 40m from OH
I found the contacts on 40m were no repeat backs and all the info was conveyed on the first try. As for 20m I was asked for repeats on my call, name and serial by most if not all the contacts. I raise the output of the KX3 to 10 watts and the external power supply seemed to handle it just fine.

An afternoon in the park.

The park setup
With the fall fast approaching which signals colder weather that is just around the corner and with that an end to outdoor op's for another year I decided to get outside today. It's a long weekend up this way with Monday being a holiday. I decided to use up some of my time off and took Thursday, Friday and Tuesday off as well. I went to our local park this afternoon and with it being a work day I did not find it too busy there I was able to get a nice spot under a shady willow tree. My first setup was an inverted "V" configuration. I was out last weekend and used the same configuration and was not spotted anywhere on 20m or 40m. I was reading this week that it's best to setup the inverted "V" with an angle greater than 90 degrees. I was not sure if that was my issue last weekend  but I decided to try again today but making sure my angle was greater than 90 degrees. I ended up having the same results with no spots. I then changed it up to a sloper configuration and I was able to contact K8DSS from Florida on 20m. Ed gave my 5 watt signal a 539 and I was happy with that but for the day that was all I had time for. It was soon time to pack things up and head home. While in a QSO with Ed his CW signal was in competition with practicing air show jets ( CF-18's and FA-18's) and the jets were

winning!  During the summer I have had on to many occasions battery issues. I have had AA cells in the KX3 not last more than a 1/2 even after a full charge. I have a Tracer lithium Polymer power pack that is an 8Ah pack. I decided to purchase the same item again and parallel the two 8Ah packs. This gives me a solid 16Ah's of power and a nice steady 12 volts. I have been using this arrangement for the summer and am very pleased with the performance.

In the park with 5 watts, KX3 and new Endfed antenna

My outdoor shack 
I had this past Thursday off work and it was time to take my KX3 out on the trail again. In my last outing I used mono band whip antenna that was mounted on my bike along with a counterpoise. After giving this setup several tries I came to the conclusion that it was time to look at another setup option. I ordered the Endfed 40-6m antenna and it came in last week and it was now time to give it a go. To get the Endfed 40-6m antenna up on a tree branch I used an idea that was emailed to me by a fellow ham. I purchased some golfballs, closed ended "eye" hooks that are threaded on one end,  carabiners and rope. The "Eye hook is screwed into the golfball, one side of the carabiner is hooked onto the eye  and the rope is loop knotted and the other side of the carabiner is hooked onto the rope loop. I chose to use  a double sided carabiner at both ends of the antenna as it allows me to fast connect and disconnect without playing around with knots. I think using the golf ball is great as it has some

weight to it and is smooth on all sides allowing it pass through leaves and not getting hung up on branches. This method worked great for me and I was able to have good control with regards to placing the golfball in the tree right where I wanted it. Once the rope was in the tree I pulled the Endfed antenna up into the tree and got down to working the bands. When using this style of antenna I was informed that an antenna tuner is a must but I wanted to check out the SWR without using my tuner.
10m                    Frequency                    SWR
                           28.020                          3.8
                           28.060                          3.8

                           21.020                          2.9

                           7.040                           8.4
The antenna was mounted in a sloper configuration the high end at about 20 feet off the ground and the other end ground mounted. The tuner in the KX3 was able to bring all bands but 40m to a flat match, I was able to get 40m down to 1.5. The bands were very quite but I did spend some time
Anchor point 
calling CQ with the goal of checking the Reverse Beacon Network when I got home to see how my signal faired. I was not heard by any European stations but I was spotted on all bands by stations south of the boarder. The Solar conditions have not been all that great lately so I was very pleased with these results. I plan on heading out again on Saturday morning and this time my plan is to try to get the antenna higher up so a portion of my antenna is not at ground level. Since the weekend is here and I hope the bands will be more busy maybe a contact or two would be nice as well.

A Tip o’ the Hat


I really have to extend a hearty "tip o' the hat" to all you QRP SSB guys out there.  Not being used to SSB operations, not being used to QRP SSB operations has provided me with a learning experience. In your writer's most humble opinion, QRP SSB has a difficulty factor of 10X compared to QRP CW.

Today during lunch time, I was hunting around for NPOTA stations on 20 Meters.  Not hearing anything on the CW bands, I moved on up to the realm of voice - foreign territory, indeed!.  There I heard two stations. K0USA on 14.260 MHz and K0RP on 14.340 MHz.  K0RP was very weak, with QSB making it worse. K0USA was a good 5X5 into NJ and even 5X7 when QSB would let up. I decided to  concentrate on Mary, who was the op behind the mic.  It took the better of 15 minutes, but I got in the log - and it was a new one for me, MN46, the Homestead National Historical Monument in Nebraska.

For her part, Mary did a superb job dealing with my weak signal.  Only 5 Watts to the Buddistick has gotten me decent results on SSB in the past, but today, with the monstrous QSB, it was their beam (which was pointed south, by the way - I was off the side) and her great ears that made the difference. I owe her a ton of gratitude for sticking with me and granting me the ATNO.

Getting back to the topic of SSB vs CW ..... I'm pretty confident in my CW skills. From past practise, it's pretty easy for me to gauge who is workable and who isn't. I still get surprised from time to time; but I've gotten pretty good at figuring out who I am able work and who I am not..

QRP SSB is still a crap shoot for me. Like I stated, it's foreign territory.  To make things even worse, shall we say that patience is a "hard won virtue" for me?  Living in New Jersey all my life, I'm used to the fast pace of the Northeast. Things, especially at work, are wanted yesterday.  I'm used to dealing with that, and delivering those kind of fast results.  The downside is, that I've come to expect that, in return.  Waiting is still a battle for me.  Not in all situations, but in many - especially when I am dealing with myself.

QRP SSB is an extra hard challenge for me and will be for quite a while. The upside is hopefully, I'll become more skilled at it; and I'll also gain more patience, because of it..
