Radio Overheating?...

I was reading today that some hams are having issues with their portable rigs overheating and shutting down in the warm weather we have been having out west while doing POTA, and SOTA, activations.

I've never had that issue.  My Dad taught me how to make a suitable sun/heat shade for any radio I might have that I want to operate portable.

The answer is a simple cardboard box big enough to fit the radio, painted gloss white on the outside, and flat black on the inside.  

The gloss white paint reflects the suns rays and the flat black helps you see your radio in the intense sunlight.  This idea is a lot cheaper than some of the responses to the original article.

Below are some photo's of the sun shade I made last year with my KX3.  It works very well. This took me less than 10 minutes to make, and the only expense was two cans of spray paint.  I hope this idea helps somebody.

July? Already?

It's definitely true that the older you get the faster time moves.  I can't believe we're already in July!  Over the weekend I did manage to complete two POTA activations, although on Saturday the propagation was not very good.

On Saturday I drove west to Trenton and then south to Carrying Place, where the Murray Canal runs through Prince Edward County.  This is part of the Trent-Severn Waterway National Historic Site, or as we know it, VE-4889.  I managed to put only 10 contacts in the log for this one, and every contact was hard fought for.  

When I looked at the propagation numbers before I left home, they looked pretty good.  SFI=94, SN=72, A Index=5, and the K Index=1.  However, I didn't see the small note about the X1.5 Solar Flare which caused a major bump in the propagation.  

I had also planned to activate Carrying Place National Historic Site, but could find no place to park so I could operate.  This is one I don't think I will be back to, it just isn't conducive to activate safely.

The third planned activation was supposed to be Lake on the Mountain Provincial Park.  This also didn't take place, not because of bad propagation, or lack of parking, but because there were just too many people wandering around and I didn't think it was safe to setup my station.  I will be back for this one, but I'll do it very early on a weekday when the crowds will not have gathered yet.

Sunday arrives and I think I had better stick close to home as it's my 34th wedding anniversary, and I would like to live to see my 35th........but the XYL asked me if I was going to go out and "play radio", well, needless to say I took a chance, said yes, and drove to activate the Frontenac Arch Biosphere, VE-0023.

Once again the propagation numbers looked good, SFI=90, SN=81, A Index=4, and the K Index=1.  But, they had fooled me yesterday so I checked them a few times to make sure I wasn't going to get fooled again.

It was early and there were not too many Park Hunters around, but this time the numbers held and I did a successful activation of VE-0023.  It was done only on 20m, normally I do it (no idea why) on 40m.  But today I reached out and 11 stations who had never worked it before got a chance to do so.

So it was a great anniversary weekend, I got to "play radio" and the XYL got some much deserved peace and quiet......a win win situation 😆

Stay safe out there!!

The ARRL Field Day - 2021...

Field Day 2021...

 

In three words: “What a Zoo”!!!!

 

As another ham said: “FD is a contest no matter what the ARRL says. Contests bring out all that type of behaviour most of us dislike.”

This Field Day was like the three stooges all trying to go through the same door at the same time.  Nobody listening out for other stations on the same frequency, nobody asking if the frequency is in use...yep, just spin the VFO, and wherever it stops start calling CQ FD right away before somebody else does.

 

The ARRL placed a power limit on the home based stations of 150w because of issues caused by the home based stations last year. Yet, there were home operators out there bragging they were using 1000w and 1500w again this year....and many of them. I heard a W4 and a K3 in particular, talking about their high power levels during one of their exchanges. If you’re not going to follow the rules, why take part?

 

There seemed to be more LIDS out there than usual causing issues this year, and the foul language on the air at times had to be heard to be believed. Perhaps it’s time the ARRL took some steps...big ones...to put an end to this bad behaviour on the bands. This isn’t the first year this has happened, it’s just that it gets worse every year.  Nobody seems to care about the bad behaviour and nobody will do something about it, so after a while it becomes acceptable because there is no penalty for flaunting the rules and the accepted behaviour standards.

This is what I wrote last year about Field Day:

"The ARRLs decision to temporarily modify the rules was, in my opinion, an absolute disaster. I'm sure the ARRL will scream that this year was the "Largest Field Day Turnout in History!" within the next couple weeks as the logs begin to roll in, and of course the numbers look good for their amateur radio publicity, but Field Day should not be a numbers game. It might just well have been any other contest weekend. 

 

The people who actually participated in the real SPIRIT of Field Day had absolutely no chance at all. They were getting completely blown away by the D and E stations running large antennas and amplifiers. That's all you heard. I'm just guessing right now without looking at my log, but I would say easily 95% of the contacts I made were Class D and E."

The ARRL did nothing about this, and this year it was even worse.  Every word I wrote last year I could write again about this year.  The spirit of Field Day is emergency preparedness, not a contest.  If you're not prepared to operate under minimal conditions and with minimum equipment, why bother taking part?

I think that after 25 years of doing them, I’m over field day. This was the last one for me.

QRP and Field Day...

Coming up in two weekends is Field Day 2021.  I'm not sure where I will be operating from yet, I'm still waiting to see what will be open by then.  My best guess right now is that I will be operating from a screen tent located on my back deck.

One thing is for certain, I will be running QRP on battery power with my KX3.  In fact I have just bought a second 1212a Bioenno battery to make sure I don't run out of power.  Remember, operating QRP on battery gives you a multiplier of +5 on each contact you make.

Here's a few QRP hints for you...

Timing is everything!  If you're operating QRP don't jump in at the very beginning because you will be severely stomped on by hundreds of high power stations, all looking to work the other high power stations.   Wait until late evening, perhaps even until early Sunday morning before you start.  There are two reasons for this.  Firstly, by that time the big guns will have worked all the other big guns and the "easy to work" stations.  Secondly, by Sunday morning the big guns are starting to get desperate for contacts and actually start listening, and work harder, to get weak and low powered stations in order to gather more points. 

Antennas, Antennas, Antennas.  You can never have enough.  I'll be using a vertical, and multiple dipoles.  A few points for you... If you're using a vertical, double the number radials you already have on the ground.  That will give you a gain of 1 or 2 db, and remember when operating QRP every db counts!!  Most people will put up a dipole as an inverted V as that is easier.  However, a flat-top dipole will gain you 1 or 2 db.  Once again, every db matters.  

Verticals are good for DX and distance.  From my QTH they make it easier to make contacts out on the west coast and down into the Gulf Coast, and more contacts mean a better score. I will be putting up a 40m NVIS antenna this year to make sure I can work into the upper States, Quebec, and Northern Ontario which I always seem to miss.

Know what band to use and when.  During the day 20m is normally the work horse, but don't forget to spin the VFO over 15m and 10m, as sometimes they open and get busy as well.  20m can remain open until late evening and you can catch some good stations as the Greyline goes through your location.  40m can also be a good place to hunt during the day, but it's a lot better in the evening and over night as is 80m. Very rarely do I go down to 160m, I find it's just not worth the effort.  

Two last things to remember.  The MUF begins to fall in the late afternoon or early evening.  That's the time to follow the greyline. And, skip normally lengthens in the late afternoon or evening depending on the propagation.

I hope you all have fun during Field Day. Enjoy the time and enjoy experimenting with different antennas.

Field Day Rules can be found HERE.

Stay safe out there!

Lousy Propagation...

The bands have not been cooperating for the past couple of weeks.  They have been noisy, full of deep QSB, and not much fun to operate on.

I did two local POTA activations this past weekend, and only just managed to scrape the minimum of 10 stations for a successful activation on both occasions.  In fact, on Sunday I started early in the morning and with only 5 stations in the log hit a wall.  I had to pack up and hope the bands improved in the afternoon so I could come back and finish the activation.......it did.  I managed another 6 to squeak by.  That is the very first time I had to come back to finish.

Those of us that activate parks around Kingston have noticed that while we nearly all now use Hamsticks, there is very little difference between them and our other portable wire antennas.  The hamsticks are sure a lot easier to put up!

Hopefully the bands will get better before Field Day rolls around two weekends from now.

A bit of a surprise...

 

Very pleased to receive this certificate, my Worked All States (WAS) from Parks on the Air.

This was much harder than getting the ARRL WAS certificate. It took me the better part of a year to work a POTA station in every state, and it was even longer than I expected due to some individuals not submitting a log and having to search again for an active park in the missing state.

Now that this is done I guess I have to find a new goal to work towards.

May, a busy month...

I just looked at my calendar for the month of May, counted up my POTA activations and discovered I did 15 separate activations.  Of those activations, 5 of them had never been activated before.

During those activations I put over 400 contacts in my log. Now 400 may not look like a big number, but when you consider I only do POTA as a QRP station with 10w into a hamstick, held on to the roof of my van with a 5" mag-mount, it's not too shabby a number.

So far June is shaping up to be a quiet month for activities, especially now that the Rideau Bike Tour has been cancelled for the second year in a row due to Covid.  

I haven't made any plans for this years ARRL Field Day yet, I'm going to see what the rest of my ham buddies are going to do first.  But if I do participate this year, it will be as a QRP station.

The decision last year by the ARRL to temporarily modify the rules was, in my humble opinion, an absolute disaster. It might just well have been any other contest weekend.  The people who actually participated in the real SPIRIT of Field Day had absolutely no chance at all. They were getting completely blown away by the D and E class stations running large home based antennas and amplifiers. That's all you heard. Looking through my log, but I would say easily 95% of the contacts I made were Class D and E. 

This year, to appease the large number of hams who complained about the D and E class stations last year, the ARRL have ruled that these classes can only run a maximum of 150w.  Yeah...well, let's see how many of them play by the rules this year...I'm not going to hold my breath.

Stay safe out there!

What A Night...

Saturday was a great night. It was our Clubs monthly HF QRP Sprint, and I decided to drive to Fort Henry and do a POTA activation at the same time.  I thought I may do well there, and I was not disappointed at all.

Propagation has not been very good around here for the past month.  The bands have been very noisy and have had a great deal of very deep QSB.  

Last night the propagation numbers were:

SFI=75, SN=13, A Index=5, and K Index=2.  We also had some deep QSB.

I used my KX3 at 10w into a 40m Hamstick mounted with a mag-mount on the roof of my van.  40m was up and down, one minute it was going long, and the next it was extremely short....so you never knew what you were going to get after you called CQ.

The Sprint runs from 1900 to 2100 local time here in Ontario, and for those two hours I hardly stopped entering stations in my logbook, it was just insane at times.  

At 2100 I shut down with 75 contacts in the log, from 22 different Provinces or States.  It was an excellent time, and I must do it again soon.

Stay safe out there!
