Part 2: What to bring for portable operations?

Now that I have some potential operating areas scouted out (with more to come as I do some more exploring) it’s time to look at what to bring
  1. An HF radio……….DUH well of coarse……I’m bringing my Elecraft KX3 it has internal rechargeable batteries and you can plug in an external power source, internal antenna tuner, CW paddles attached to the radio, up to 15 watts of power thanks to the recent firmware upgrade but I will stick with 5 watts and many more portable friendly features.
  2. The antenna……..I have chosen to use mono band whip antennas. I have the Workman HF whips from 10m to 40m and a great carry case for them. I’m able to Velcro strap them to the rear rack and to the front bar on the bike.
  3. Spare external battery and I have already the Tracer 4Ah rechargeable battery. I was looking at other batteries but I figured “use what you already have”.
  4. 3x5 cards with some of the common command functions of the KX3. Such things as setting up CW Keyer memories and playing them,memory setup and recall and dual watch if needed.
  5. Bring some info on the contests that may be going on that day as I can scoop some contacts that are in a contest. It’s handy to know the exchange they are looking for in the contest.
  6. Then there is the miscellaneous  stuff such as coax, pen, paper, cell phone and don’t forget bug spray, sun screen, sun glasses, water and a hat.
  7. Make a list ahead of time that what to bring………there has been to many times to count when I thought I could remember everything only to find out I missed something and I was not able to operate because of it.



Part 1: Getting ready for outdoor operations.

April has arrived with not showers but a snow storm! We have had snow falling and accumulating all day today and it's forecast to snow most of the evening. To me it seems a good time as ever to think about my summer portable operations. A few weeks ago both Julie and I purchased new bikes and these bikes are amazing compared to our old ones. My plan this summer is to utilize my new bike for portable ham radio outings. My first step is to check out some areas in the neighbourhood were I can have my first few radio outings. I was looking for locations that would allow me to concentrate on my portable setup and workout the operational glitches. Each day I go out for a 40 min walk in and around the Lake we live on. These last few days while walking I was paying attention to spots that would be possible portable radio op spots. My criteria was close to home just in case something is forgotten, an easy ride to get there and sites that are easy radio setup and operation. This would allow me to work out the radio "stuff". Here are 3 locations I have scouted out so far......
This spot being right on the lake during a very warm day will have a nice cool breeze. Also if the sky is threatening rain I would have shelter to continue my operations.










This location is nice as it has a large bench to setup on but the weather will have to co-operate as it's out in the open.










Once summer arrives the trees at this spot will provide some nice shade plus it's a nice view to boot.

My CQ WW CW contest overview.

The QRP setup
I had a great part time effort in the CQ WW CW contest, I was not concerned with score or putting in a major amount to time in the contest chair. The key goals in this contest was to see how my CW reading by ear was doing and when on the rig to stay with it for the time I committed too. The reading code by  ear was fine up to speeds in around 25 BUT with some stations they were flying at around 35-40 wpm and that is just to fast. My code reader MRP4066 handled the high speed code no problem this software is not free but I found it to be the best! I entered the contest as single op, QRP single band (15m) and I met the requirements as a "classic" operator  I added this overlay to my submission. My total QSO count was 33 a score of 3,128 points and 10 zones. At my QTH I did not hear the usual amount of European stations I have in the past. My operating time was during the day from late morning to until late afternoon. During the late morning I head mainly Caribbean, African and some European stations but not many. As the afternoon approached more South and Central American stations came it as Europe faded.
I did have some "Murphy" moments such as…….I was not able to get my MFJ mag loop to tune at all at the start of the contest. Very quickly I found it was a very loose PL-259 connected on the rear of the loop's control box. Then for some reason N1MM+ set my CQ zone as 5 and not 4 and I did not click into this until about 10 contacts into the contest. Finally on the K3 there is a "test" setting and I use it to check macros without transmitting. Then old age had me forget to turn off the test mode, this found me thinking I was calling stations but was transmitting 0 watts….. Now that's QRP!!
Since I am operating QRP and using small MFJ loop antenna on the balcony my operating style was as follows
- I Use my VFO B to save a strong DX station that at the time has a huge pileup going. This stops me from wasting time trying to break the pile. Better to come back when the crazy pileup is gone. This worked great when I came across a Senegal station.
- Even when a station is at an S2 level but is just calling and listening my 5 watts can and did many times make it through for a contact.
- I don't use a spotting network as I found most of these stations have a huge pileup but I do have an Elecraft P3.  Using some hardware and software my P3 is seen on a 19 inch monitor and I am able to point and click on signals. My K3 then moves to that signal this allows me to see the activity on the band and Search and pounce these stations.
- When possible stay with a band such as 15m were my MFJ loop does not need to be retuned at all across the whole CW portion.
- Stick with my 250hz Inrad 8 pole CW filter so I can get between tight signals and only hear the op I want to contact.
In my post I am going to go into detail about my software I am now using and finding to be great for contesting and general QSO's It's now time to grab some eats and relax.

Out and about with my KX3 radio

The KX3 being used in my lap.
It's the Easter weekend and I normally get the Friday and Monday off work but this year I decided to also take the Thursday and Tuesday. Today was to be a great day with the temperature in around 17C the forecast was for sunny skies in the morning and early afternoon but then rain rolling in for later in the day. I decided early in the week that with the nice weather I was going to make today an outdoor radio day........well from the car just a bit muddy and wet to setup outside just yet. I took  my Elecraft KX3 and some mono band HF whip antennas that attach to a mount on my car. I set my sights on 15m and the conditions seemed great and the DX was rolling in. For the time I was on the DX contacts that I made were:
1. I1YRL from Italy and Luc was very strong and no fading what so ever. While talking to him I found out that in the summer of 2014 he and his wife visited Toronto. Luc gave my 5 watt QRP signal a report of 579. Luc was very surprised I was QRP 5 watts using a mobile whip from my car. 
2. EG90IARU/5 this was a special event  again they were booming in and I was able to make the contact on my first call. This was a very fast contact with the usual 599 report.
3. IT9NJE and Gene again from Italy gave me a 549 signal report.
Over all I was very pleased with my hour on the radio from the car out in the park. I was happy I did not have any Murphy moments but I did have an "old age" moment..................I installed the 15m mono band whip antenna on the car. For some reason (old age) I set the KX3 to 20m and could not understand why the antenna tuner was needed everywhere on the band! Then in occurred to me I was on 20m using my 15m antenna. Once that was sorted out the morning went very well.

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!

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

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.
