Contesting at QRPp levels!


Yesterday I dabbled in the OK/OM DX CW contest for about an hour and a half. This time for some fun and interest I entered QRP level but lowered my power to just one watt. Propagation has been surprisingly nice over the past week or so and I wanted to give the new solar flux a test run. My radio is the Icom 7610 and my antenna is a slopped Endfed antenna at about 25 feet. I stayed on 20m as the radio gods seemed to be smiling on me there. I made only 10 contacts as I was not in the contest for scoring just to see how the fishing was with one watt. I was only asked for repeats regarding my exchange twice other than that the 1 watt made it through. 

Because I was operating at only 1 watt I also wanted to take the loss of my SWR into account. I checked with my antenna analyzer and the CW portion on 20m my SWR was 2.3:1. According to the power loss at various SWR readings chart at 2.3:1, I was in around 15% so this took my 1 watt down to 850 milliwatts. 

Below are the results of my QRPp contest efforts: 

Band     20m

A fast cool trip to the park

Starting out on my cool walk
CHA P-Loop antenna
I had the day off work today and it looked very nice outside, the sky was clear and the sun was out. I wanted to take this opportunity to test out my new portable antenna. I packed up my Elecraft KX3, batteries, key and my new Chameleon CHA P-Loop antenna. This post is not a review of the new antenna before I do that I want to try out the antenna several times. Before heading out I did not check the propagation reports, I find if I do this and they are poor it casts a shadow over the outing.As I was saying the day from inside the house looked nice but once out there was a cold wind off the lake, it felt like a cool fall day and not spring. Anyway.....because of the poor weather, my lack of warm clothing I quickly setup the antenna, checked out how it tuned on 10, 15, 20 and 30m and gave a few CW CQ's. With no answers and the wind picking up I was satisfied the antenna at least worked.

A 40m WSPR weekend

40m from 7am-7pm local time
With the Solar cycle heading on a downward trend I have been reading how 40, 80 and 160m may be the bands of choice for QSO's. Since my MFJ 1788 will only venture down to 40m and at the best of times I have found it to preform like a wet noodle on this band. I decided this weekend to give WSPR a go on 40m using 1 watt to see what results I got. My 1 watt signal was picked up throughout Canada and the U.S. There was a one off to Spain but the consensus from WSRP.net was on 40m my DX was going to be North America. There was one odd report which repeated itself over and over, it was from WY1R saying he was hearing me on 6m?? Not to sure what that was all about. I also was checking with PSK reporter looking at WSPR mode and funny thing was there was never any hits for my call?
40m from 7am-1am local time

100mW's of raw power!!

The other evening I was having a cup of tea and checking out my new QST that just arrived and found myself very interested in a piece written by Steve Ford in his column Eclectic Technology. The title caught my eye "When a signal is barely a WSPR" Steve looked at how the Raspberry Pi could be used for WSPR transmissions. Seeing I have the Raspberry Pi3 this sparked my interest. It was pointed out that all you need to turn your Pi into a WSPR transmitter is a board from TAPR called QRPi.  The board is offered at a very reasonable price of 29.00 U.S and it's set for 20m at 100mW. Before I got to excited about this little project  I wanted to see if using 100mW's would net me any results. I have seen other hams in the past net great results with far less than 100mW's and WSPR is known for it's great decode at very low power........BUT.......I do have a challenging setup here. On Friday late afternoon I gave WSPR a go on 20m at 100mW and was I impressed with the results. I was received by DK6UG for a distance of 39383 miles per watt and also ON7KO for a distance of 37285 miles per watt. I was amazed that my setup was able to produce those results! Now another question I wanted to consider is at 100mW how much of that actual power makes it to my antenna? To do this I referred to a coax calculator I punched in the type of coax (RG8X) the SWR (1.4:1) the length (30 feet)  the frequency (14) and finally the power (100mW) The calculated amount I was informed was 92mW of raw power! So this bumped my miles per watt to 42810 for DK6UG and 4053 for ON7KO! It's not timo look more into the TAPR project!!

VE3WDM is back into QRPp very low power contacts!

I was feeling under the weather this weekend and thought it would be nice and relaxing to spend some time on the radio. It so happens a CW contest was in full swing the Russian DX contest. I was not into competing but just handing out points. The propagation conditions this past week were a struggle to say the least. Today the conditions were on the rebound a K index of 2 and the Sunspots were in at 27 and the solar wind was still up at 615. I parked on 15m and there was lots of DX rolling in for the contest. I made only 7 contacts for Saturday (so far) most were done with QRPp power! I was very pleased that my condo antenna was able to get out to make some great QRPp low power contacts. My K3 is only able to get down as low at 100mW's silly me I sold my attenuator thinking my contacts under 100mW's were over! I was able to make 3 contacts at milli watt power, 2 contacts at 1 watt, one contact at 3 watts and finally 5 watts. My first QRPp contact in the contest was K5WA in the states, my next QRPp contact was with EA3CX in Spain. Then finally F5IN in France with 500mW's of power.
The 7 contacts break down as follows
1. F5IN          500mW          7,500 miles per watt
2. K5WA       100mW         13,213 miles per watt
3. EA5CX     100mW         39,956 miles per watt
4. DK3QZ     1 watt             3,818 miles per watt
5. DL0AO     1 watt             3,818 miles per watt
6. HC2SL      3 watts            
7. ZF2DX      5 watts

Making your radio time interesting is what counts!

I spent some time on 20m in the CW portion of the band and as always I wanted to make contacts with the lowest power possible. I came across 9A2G who was calling CQ and at the time he was not to busy with takers. This is a great opportunity for me to drop my call to someone who is listening. I started out at 500mW's and moved all the way up to 5 watts and nothing no contact. He did have some stations answer his CQ  and some where very weak so  he had good ears but not for VE3WDM. I then came across EG7MAL and I worked my way up to 5 watts and he came back to me with VE3?. He decided to move on as I was just not making the trip. At this point I was wondering how my low power signal was doing so I decided to call CQ at the QRP watering hole on 20m. I was checking with the Reverse Beacon Network to see how I was doing.  My 500mW signal was heard by AA4VV in North Carolina which was just over 1,000 miles per watt. I then bumped my power up to 1 watt and was very happy to see F4DXW was hearing me which meant my 1 watt of power made it 3461 miles. I did not make any contacts but I did find a way to make the radio evening a bit exciting even without making a two way contact.

Another QRPp contact with the MFJ 1788 antenna

Transmitting with my wet noodle
I was off work on Friday and in the afternoon I found some time to get on the radio, I was pleased to see conditions had somewhat improved. The bands most active for me were 20 and 17 meters. The MFJ 1788 loop was very good at picking up DX I heard but was not able to contact G3XOV from England his signal was a strong S8 but as I waited for him to clear the callers who were before me his signal faded to S2 I still tried but was not able to make the contact. I then came across a station who's call started with "Z" that letter always gets my attention. From these parts a "Z" call could be very good DX. The call was Z63MED very odd call I thought maybe a special event station, I looked it up on QRZ.COM and found out it was a station from Kosovo. This country is still a developing story when it comes to ham radio. It does not as of yet have DXCC recognition as it just became a country in 2008. For more Kosovo ham radio history go to QRZ.COM and look up the call Z60A this is the call for the Amateur Radio Society of Kosovo.
Now for the exciting news…….I ended up only making one contact and it was with EG4GET and this I found out was a special event station in Spain and has to do with football or soccer as we know it here in North America. There are 20 special event stations you can contact and contact (from North America) with 5 gets you a silver award and 10 will get you the gold award, for more information follow this link . So back to the exciting news…….I dropped the power on my K3 to 1 watt and made the contact with this special event station without really any trouble for a distance of 3,754 miles per watt! Looking back when I moved into the condo and only being able to use a small antenna  in less than ideal conditions I felt my DX was going to be south of the boarder and that's it. I have come full circle to hitting over and above thousand miles per watt contacts. My record for miles per watt at this location is still 18,470 per watt in the ARRL CW contest.

Shut down two days in a row!

A foggy view of Toronto from my setup
This weekend I planned on getting some radio time in Julie was going to see a friend who lives out of town on Saturday so I thought I would get out and get hamming. We live right on Lake Ontario and within a short walk and or bike ride there are some great locations on the lake to do some portable op's. On Friday night I charged up the KX3, set out all of the needed items for outdoor ops. Saturday came and off I went, I decided to walk and it turned out to be a longer walk then I thought. I arrived at my
Trail on the way there. 
spot and setup the KX3 along with my Alexloop. Just as I sat down to get some operating time in it started to rain! With no rain gear and about a 1/2 hour to walk back I packed things up and headed back. Well I tried it again on Sunday and this time I took my bike and some rain gear just in case. This time I set everything up and was ready to go until I tried to connect the Alexloop to the KX3…..it seems for some reason I removed the adapter that allowed me to go from PL 259 to BNC at home! There was no way to hook up my antenna to the KX3 radio so I decided the radio god's were just not smiling on my this weekend and I headed back home the long way to tour around the lake.  Lesson learned I now plan to make up a small 3x5 card with all that is needed for the trip.

Sunday radio time.

MX0CCE Bob 
Not much going on
I was able to get some time on the radio Sunday afternoon, there were some contests going on but did not seem much other than that. At the same time I was able to get my radio control program (N4PY software) to work along with my logging program (N3FJP's AClog) and I found out that there is a cluster program that is offered with the N4PY program. It also has been integrated very nicely. Back to my on air time……I did run into two very strong signals calling CQ and giving signal reports. The first was MX0AAA It's a club station that was founded in 1934 and according to the map on QRZ.COM the station is located in London England. The contact was made on 20m with 5 watts and my signal report was 559. I then saw another strong signal on my P3 again on 20m. The call was MD0CCE and Bob was located on the Isle of Man and my signal report was 579. That was it for the contacts for the weekend. I was very pleased with these two contact for QRP and the MFJ Loop antenna

Sunday evening on the radio

This weekend brought great weather and so it was out and about with Julie, but I did find some time for radio on Sunday evening. The bands were busy with contests and not wanting to get involved with them I skipped up to the QRP watering hole on 20m. I started calling CQ as I could not hear to much action. In a very short time W5TM came back to me and I was only 449 but it was a contact and that was good enough for me! Our QSO did not last to long as I was very much in and out I did send Edwin an email thanking him for the QSO. During my next CQ calling a G station came back to me but they were down in the mud. I switch on the APF and we did try over and over again to make contact but things just did not work out. It was pretty cool that my QRP signal was somewhat making it into "G" land. My last contact for the evening was with KA5KMS and this was a long QSO with a solid contact at both ends. Terry was running a Ten Tec Century 21at 25 watts into a dipole.  It was a good evening on the radio! They all were short QSO's but it will help keep me in the hobby, keep my code up and help me become more and more aquatinted with my rig. I have found that I can easily get lost in my ham programs, antenna issues and PC hiccups that involve radio. Bottom line it's great to put all that to the side and get on the radio and make some good old contacts.

Day 3 of ARRL CW contest time to drop the power!

Pumping out 1/2 a watt
On Saturday I was very pleased to see that my MFJ 1788 loop antenna was getting out. On Sunday it was time to push my luck to the limits, here are VE3WDM I always like to see how little power it take to make a contact. It seemed yesterday 5 watts most if not all the time was getting through. Why stop at 5 watts it was time to drop the Elecraft K3 below the 5 watt maker.............wayyyyy below! The conditions once again were very nice Flux levels were up along with the Sun spot count but the K index was also in around 4. That did not seem to matter the bands were full of contest action. Once again I stayed on 15m and it was very busy with DX from the contest. Today I made only 20 contacts as there was chores to get done around the house.
Hard at work
Yesterday's post concentrated on the country count and locations today's post is all about power levels and miles per watt. From 5 watts I dropped down to 2 watts to see what would happen and DK3GI was in my cross hairs. I was able to make the contact first call which gave me 2020 miles per watt. From there on out of my 20 contacts 19 were all over 1,000 miles per watt. Here is a run down:
1 contact made at 3 watts
4 contacts were made at 2 watts
7 contacts were made at 1 watt
6 contacts were made at .5 of a watt
1 contact made at .1 of a watt
1 contact made at 5 watts ( this being the only contact not netting me 1000 miles per watt)
Some of the miles per watt numbers
II9P at .5 of a watts netted me 18,470 miles per watt
K5RT at .1 of a watt netted me 11,808 miles per watt
CN2AA at .5 of a watt netted me 7682 miles per watt
F8CIL at .5 of a watt netted me 7662 miles per watt
F5NBX at .5 of a watt netted me 7608 miles per watt
CS2C at .5 of a watt and netted me 7216 miles per watt
This contest I was just a point giver and not in the contest to submit a score. I wanted to test out the MFJ 1788 antenna to see how my location and antenna performed. Some things that still have to be done, I have to get the contesting software and radio control software up and running. Have the SWR problem on 10m and 20m figured out with the MFJ 1788 loop, for some reason the best SWR I can get is around 9! On a positive side this contest proved to me that the antenna will get out even with QRP or QRPp power!!

Some very big changes at VE3WDM

Goodbye crazy driving
The new temp antenna
I have been very busy these past few weeks and my lack of blog posts can testify to that. Julie and I have been bouncing around some very big ideas. We have some very exciting plans ahead of us that will both help our over all well being. It also will bring about some huge changes with my hobby but I am very happy to say that it's a challenge I can meet. Both Julie and I have over an hour drive each way to work. We get up very early, get home late and to be early each evening. Then there is the winter months with the snow and crazy driving. We have decided to put our home up for sale here in the country and move to Toronto. We will be living in a condo as our kids have moved out and are doing just fine. This means downsizing both with our home belongings and my ham radio. We want to get a place that is in Toronto and over looks Lake Ontario. Both Julie and I are very excited about this and with this move I will be 10 min's from work and Julie 15 min's. We will have a fantastic board walk just steps from out condo. It thrills us that all the advantages of the city will be not an hour away but minutes.
So how does this affect radio for me.....well my Attic DX EE has been sold and already is taken down! Not to worry I still have my Alexloop that I can set up in my radio room until we sell and move. I have some gear for sale and it is slow but sure selling. I have sold the Sub receiver in my Elecraft K3 as I will be very limited with antennas in the new place. I don't have any room for an antenna for a sub receiver.  So I have been going over antenna options in a condo. There are far and few BUT one main advantage I will have that I don't have now is height! In the condo we are looking at the 11th floor and
up. I am thinking of using at first my Alexloop and then going to the MFJ loop antenna. This will be a new adventure in my QRP ham radio challenge.
Changes are coming

Short time on the radio netted 37,968 miles per watt contact.

Last evening I had a very short time on the radio I was not expecting much as the conditions have not been stellar. I did find 20m to be very busy and not reflecting the solar conditions. On May 2nd I was able to work EA4DRV and last night I heard him on again calling CQ. I gave him a call and made the contact with only 100mW's for a miles per watt of 37,968! Shortly after my contact I heard him giving a report to fellow blogger Larry W2LJ. I was only able to hear Larry very faintly just above the noise level. I did do a little more fishing but time was tight and I had to shut things down for the evening. This evening I think I am going to throw the line out again and see how the fishing goes!

Nice openings on 10m

Signals on 10m this afternoon
Sunday afternoon has seemed to pass just a little faster with setting our clocks ahead last evening an hour. I did find some time to get on the radio (finally after about 5 days off). I tried 10m and according to the P3 screen things were fairly calm for that band. As I was starting up my PC along with the DXlab software I did notice some small and large spikes on the P3. Most of the time when the band is this dead and it was about 2 in the afternoon as well these spikes are just QRM.
EA2LU antennas
Upon investigation to my surprise the first spike was a signal from PV8ADI in Brazil. For some reason I have had troubles with South American station. Not sure if it's the position of the dipole in the attic or just one of those always hard to get spots for me. I gave the station a go with 500mW's but as I expected....nothing. He was having lots of stations (ones I could not hear) come back to him. The flavor of the contact was signal report and move on. I brought the K3 up to 5 watts and gave him a another call. He came back to me and we exchanged reports and moved on.

New records set at VE3WDM!!

Julie was out and about snapping shots!!
For me the ARRL  DX CW contest is over, I have some blog, email and cleaning to do for the rest of the day. Over all the contest was a success for me not that I broke any records with regards to points or number of contacts. I was very pleased with how the station and antenna were working, I find that contests are a great way to see how the rig and antenna preform. With regards to the rig and software I merged N1MM logger and N4PY rig control software through LP-bridge and as an added bonus I was able to also use the Flexradio's flex control vfo knob.....now that was a mouthful!! Lets break this down shall we N1MM is the
At 40mW and below this is the reading
contest logger that I use, N4PY is the software I use to control my K3. LP-bridge is a virtual port program that allows these two programs to somewhat talk to each other. I say somewhat as there are some minor issues. (there is another virtual port program VSP manager that allows perfect integration but I did not want to install it just before a contest) Oh and the FlexRadio FlexControl works fantastic with N4PY's rig control program and through LP-Bridge also works with N1MM as well. Another software program I ended

Up coming ARRL DX CW contest.......

Last years action
It's that time of year again for the ARRL international CW DX contest. The bands will come alive with CW, I hope my CW practice will pay off and I can copy the fast guys!! Last year my goal during this contest was to pick up as many DXCC's as I could. My plans were by year end to have 100 DXCC's QRP in the books. That plan did not work out as I was just a few short of the goal. Another goal back then was to spend more time in the chair operating. This is were I really struggle and end up shutting things down early so we will see what happens this year.
Goals for this years contest

Snow day = radio time!!

Working the KX3
OQ5A setup
On Friday I was able to take the opportunity to get some well deserved radio time in. Most weeknights when I get in from work and get the "house stuff" done I find I'm just to tired for the rig. On Friday I was able to fire up the KX3 and try my hand at some QRPp operationing. I was scanning up and down 20m's and found OQ5A from Belgium calling CQ. I adjusted the KX3 to 100mW's of power and gave OQ5A a go, he came back to me and with just a few repeats all the contact info was passed along and the QSO is in the books. This contact  at 100mW's netted me a distance of  37,603 miles per watt.

QRPp is just getting really great......

I posted yesterday I had contacted F8EI and in the heat of the moment I had thought I contacted  him with between 20 and 14mW's of power!! I was thrilled when the contact ended and my calculations done it showed the distance at (I used the higher wattage of 20mWs) 181,958 miles per watt. I was thrilled and it was off to another contact to see what I could do for more miles per watt. On my Hendricks attenuator there is a bypass switch and I use it as the audio also is attenuated. I found another contact and switched in the Hendricks attenuator as I was transmitting I noticed the power output was around 150Mw's!!!! Did I read the meter wrong in my excitement.....I already sent an email to F9EI with the news of a 20mW contact. I was very discouraged not knowing what I was reading during the contact. Well 140mW's in nothing to laugh at and the miles per watt is still impressive.
Today I was looking through some recent photos on my PC of my shack setup as I wanted to change the wall paper on my PC at work. I was looking at pic's from yesterdays contact being the most recent pics of my shack. In one of the pic's was a shot of the rig and Hendricks attenuator, as I zoomed in on the attenuator the slider switches used to attenuate were not in the same position as they are right now! I had never repositioned the switches so I got to thinking Hmmmmm when I hit the bypass switch did I move the one attenuate switch that is out of position according the the picture?????. I turned on the K3 and moved the switch back to the position in the picture and took a reading on the meter and it was bouncing between 20 and 14mWs of power as the key sent out dits and dah's.
HOLY COW I did contact F9EI with (lets use the higher output) with 20mW's and I was not reading the meter wrong after all. It was me who inadvertently moved an attenuate switch to off along with the bypass switch. Just to test I checked the output with this attenuate switch in the off position (opposite of the pic I took just after the contact) and low and behold I was getting around 150mW's. Bottom line I really did make a 181,958 miles per watt contact!!!!

KX3 is working and so is QRPp

Yesterday when I got home from my failed out door op's adventure with KX3 I found out what I did. It was operator error on my part. The night before I failed to understand the KX3 charging procedure fully and I was rushing to get the battery charged for the next day. I thought I had put the batteries on a 16 hour charge by misunderstanding the simple procedure I inadvertently stopped the charge cycle. So in the morning I did try my KX3 on battery power and it did  not work but I discovered in the manual that the radio power on thresh hold had to be lowered when using NiMH batteries. I did this and the KX3 came to life. Little did I know that was all the life the batteries had in
It's charging!!
them most likely a very small factory charge.....Yesterday when I got home I looked over the instructions this time more slowly. As I went through each step at the end a time count down appeared along with "BAT CHG". I never saw this the night before! This meant is was WORKING and charging. New next few day here the temps are

The 2012 log book..........

In 2012 according to my log all my contacts were CW and QRP or QRPp type contacts. This is the 3rd year that I have made just CW contacts. The reason being SSB in the past would bother my neighbours and since this is a stealth operation SSB is OUT. As for the digital modes I just have a very low frustration factor not a good combination for setting up digital modes. Maybe 2013 will have me mellow a bit to try the digital modes again.

Club log was great in helping me get a snap shot of my log for 2012. According to Club log I was able to hit 125 QRP DXCC contacts for the year! Unfortunately I was not able to qualify for the ARRL DXCC Jubilee award as they were not counting all the DXCC entities. I was able to accumulate 83 DXCC's toward that award but this award only ran for the year of 2012 so I came up short.
My contacts for the year were 500, I thought it was a lot more but there were times I would forget to log contacts. BUT I almost doubled my contact total from the year before of 258. Seems I have to get away from the soldering iron and on the rig more!!
I was able to make it into 23 CQ zones
Some of my highlight contacts were Gibraltar, Iceland, Kazakhstan, Jordan and ST. Pierre & Miquelo.
Finally I was able to better my 1,000 miles per watt distance to 45,869 miles per watt with a QRPp contact to HA8JV with 100mWs of power.
