Proper use of a phonetic alphabet can be very helpful when working phone under marginal conditions. I’ve written a basic article on phonetics over at HamRadioSchool.com, so you might want to review that. I recently came across an article by Andy/AE6Y on some tips and tricks to use during contests. He does a super job of explaining why the ITU phonetic alphabet isn’t always the best choice. I don’t usually reprint other author’s work on this blog but somehow this article really got my attention. Reprinted here with permission. – Bob K0NR

Phone Contesting Tips For DX Contests

Andy Faber, AE6Y
3/29/18

This article is prompted by the recent WPX SSB contest, in which I worked thousands of guys from Aruba as P49Y, which engendered much reflection (and teeth-gnashing, to be sure) about how U.S. hams can be best understood from the DX end.  I’m not addressing this to relatively clear-channel domestic contests but to the situation where you are trying to get through to a DX station that may be hearing a pileup, plus noise, ear-splitting splatter from adjacent stations and all of the other sonic annoyances that make many contesters prefer CW. If there is no pileup and you know the DX station can hear you completely clearly, then you’ll get through regardless, but if not, here are some suggestions:

First, be sure you are calling on his exact frequency.  In CW contests, it can be helpful to separate yourself from the pack by calling off frequency, but that’s not true in SSB.  Off-frequency stations sound distorted and are hard to understand.  The DX station may well come back to a weaker, but more intelligible station that is on frequency, even if you are louder.  In order to work you, he has to figure out which way to adjust the RIT, and then go ahead and do it. A tired operator on the other end may just not bother, until he has worked everyone else.

Second, make sure your audio is clean.  It is so much easier to understand clear audio, even if it is weaker than a louder, distorted signal.  KH7XS mentioned in his 3830 posting that this year there particularly seemed to be over-processed signals coming from South America, and I noticed the same thing.  It used to be that the Italians who were the worst offenders, but they seem to be better now.  This weekend, the Cubans were particularly hard to understand. The prize for the easiest audio to understand goes each contest to the hams from the British Isles.  The G’s, M’s and their derivatives invariably have very clean (and usually nicely treble) audio that can be understood even when the signal doesn’t budge the S-meter.  On several occasions I chose a weak but clear Brit over a loud, but distorted, competitor.

Ok, so you have a clean signal and are calling on frequency, now how do you get the information through, both your callsign and your contact number (for WPX)?

Here are some tips:

If you are loud enough and have an easily recognizable call, you can skip phonetics.  So this weekend, when K1AR called, he was easy to pick out, same for K3UA, K3ZO, N6AA, and a few others. But for most guys, and when in doubt, use phonetics.  Endless bandwidth has been expended on the subject of phonetics, and people have differing opinions on the topic, but here are my thoughts from being on the DX end:

The first thing to understand is that the standard, “recommended” international alphabet works dismally in marginal conditions.  The words are too short, and some don’t have unique sounds. Generally speaking, the one-syllable words just get lost, while the two syllable words are better, and the longer ones are even better.

Thus, one-syllable words like “Fox”, “Golf” and “Mike” are horrible.  Some of the two-syllable ones are OK (e.g., “Hotel” and “Quebec”), but others, such as “Alpha” and “Delta”, or “X-ray” and “Echo”, “Kilo” and “Tango” sound very similar, so are easily confused.  I worked a guy with the suffix XXE, and had to get a number of repeats until he finally said “X-Ray X-ray Ecuador,” which did the trick.

There are two basic cures for these problems. The first is only to use these crummy phonetics the first time as a trial.  If the DX station asks for a repeat, say your call twice, once with the standard phonetics and once with different ones.  Don’t just keep repeating your call the same way.  Something in either the way you say it or the way the DX hears it is creating ambiguity.  If you keep repeating the call the same way it may well be that part of it is just hard to decipher, and it may not get any easier.

If the DX station is a good English speaker then custom phonetics may work, such as “King George Six…” In fact when I thought a KK4 station was a K4, he used a very effective phonetic, “King Kong Four…” WA2JQK uses “Jack Queen King” in domestic contests, but that won’t work well for non-native speakers.  The Wyoming station N7MZW uses “Many Zebras Walking” sometimes domestically, but I noticed he was using normal phonetics in WPX.

The second approach is to switch to the geographical phonetic alphabet.  This features longer and more distinctive-sounding words, which are much easier to understand.  For example if your suffix is, say, HLF, then you can say “Hotel Lima Fox,” then try “Honolulu London Florida.” When I give my call with last letter “Yankee” and get asked for a repeat it works much better to say “Last letter Yankee, last letter Yokohama.” Many of the geographic phonetics work particularly well for speakers of Romance languages like Spanish and Italian (e.g., terms like “Guatemala”, “Nicaragua”, and “Santiago”). There are a few letters for which there are not good geographic equivalents.  Obviously, “X-ray” is one of them. For “Echo”, “England” is sometimes used, but “Ecuador” is better.  Although “London” and “Lima” are both geographic terms, “London” is much better.  And “Denmark Mexico” is many times superior to “Delta Mike.”

Numbers in the callsign can also cause trouble.  What if the station comes back to “K3” instead of “K6”? In general, just try to repeat the number, but if he still doesn’t get it, you can try counting, e.g. “Kilo Six, 1, 2, 3, 4, 5, 6.” Or for us West Coasters, “Kilo Six in California, West Coast” can be useful.

Which brings me to the subject of numbers in exchanges like WPX.  I commented in a 3830 post a few years ago that the English numbers that everyone uses are just too ambiguous, most of them being plain too short.  I recommended using some Spanish numbers, like “cuatro” and “ocho”, but that suggestion went nowhere, so I hereby drop it, unless you are trying to get through to a native Spanish or Italian speaker.  In fact, In WPX, I just couldn’t understand a number from a CO8 station with terrible audio. I kept asking, “your number 424?”, “your number 242?”, “your number 224”, etc. Normally, one doesn’t confuse “two” and “four,” but this guy’s audio was driving me crazy and I wasn’t sure how well he was understanding me either.  Finally I had the presence of mind to ask in Spanish, and when he said “dos cuatro cuatro,” he was in the log.  If he had said that in the beginning I would have understood him in spite of his maladjusted audio.

One source of confusion for the DX station is not knowing how many digits there are, particularly later in the contest when a number can have 1, 2, 3, or 4 digits.  There are a couple of ways to help. For example: suppose the DX station thinks he hears “[garble] six six” and he asks: ”your number six six?” If your number is just 6, you can say to be helpful “Negative. My number zero zero six, number six.” Adding the word “number” in front of the digit indicates there are no missing digits.  If your number is 66, just say “Roger, roger.” If it’s 56, say “Negative, number five six, fifty–six.” If it’s 256, say, “Negative. Number two five six, two fifty-six (or even “two hundred and fifty-six”). I know we were taught that it is incorrect to say “two hundred and fifty-six,” and we should just say “two hundred fifty-six,” but using the “and” makes it more intelligible.

In general, it’s usually best to say your number twice, in two different ways.  For example it’s often hard to discern, “two three” from “three three”. So you can say: “five nine, two three, twenty-three,” since “twenty” and “thirty” sound very different.  Similarly if your number is 15 and you say “one five”, that might be confused with “one nine”, so say “one five, fifteen.” If it’s late in the contest and you might be expected to have a three-digit number you can say “zero two three, only twenty-three”. And if you have a one digit number late in the contest, it’s best to add zeros, saying, e.g., “zero zero nine, number nine”, not just “nine.”

I hope these tips from the DX end are helpful.  They should be even more useful in the next few years, as declining sunspots forcing us increasingly into the QRM alleys of 20 and 40 meters.

Hello everybody! In this episode of the Everything Ham Radio Podcast, I am stuck by myself talk to yall. I unfortunately didn’t remember that I my next scheduled update was due until 4pm the day before. So I worked all afternoon, while at work, trying to figure out what I was going to talk about. When I got off work at midnight, I ran home and did my couple honey-dos and then went straight to recording the episode.

So what is in this episode?

First off, I made a mistake! Yea, I know, nobody is suppose to make mistakes right? Well, in my last episode I did. In last episode, my semi regular co-host Ian KM4IK and were talking about the big stink that was doing on with some things that the ARRL Board of Directors were going to be voting on. Neither one of us were really up to speed on the whole thing as much as we should be, but we did our best, and we even said that we weren’t. However, after the episode I did receive multiple emails saying that I said something wrong, so I corrected it in this episode.

With that out of the way, I went on to talk about an upcoming event called the School Club Roundup. It is this month only a few days away actually. The event run February 12-16, 2018. It is an event that is geared for school amateur radio clubs to get on the air and make some contacts. Even if you are not in a school club though you can still get on the air and make contact with the school clubs that are on the air and help them make the points.

After that, I moved on to Hamvention. Another correction from last episode. Well I say correction, this time it wasn’t me though. In last episode we talked about how a new building was going to be built and available by this Hamvention. However, this week, the Hamvention committee released that it wouldn’t be started on until later in the year due to a material shortage.

I wrap up the episode reading some emails that I have received over the past few weeks. The last episode of 2017, I told yall what my plans were for 2018 and asked what some of yalls were and also asked some questions about what were yalls opinions on how my show is. I got a few responses, wish I would’ve had more though.

Until Next Time Yall…

I’m sure that you have heard of NPOTA, National Parks On The Air, and SOTA, Summits On The Air, and probably even POTA, Parks On The Air, The US program for the World Wide Flora and Fauna, but have you heard of the latest event that starts on Sunday, Dec 11, 2017?

Starting at 0000 UTC time on December 11, 2017 the new year long event celebrating multiple anniversaries for the NASA program will start. It is called NOTA or NASA On The Air.

With several NASA clubs doing several special event stations of the coming year, they decided to make a year long event where you, as the end user, can contact the stations to earn points through the year. You can even gets points during other events like Winter Field Day, the ARRL Field Day and others.

Losten to my latest podcast episode where I talk with Rob Suggs about it:

Are you participating in this year’s CQ World-Wide DX Contest, either the SSB weekend (this coming weekend, October 28-29, 2017), or the CW weekend (November 25-26, 2017)?  The CQ WW is the largest Amateur Radio competition in the world. Over 35,000 participants take to the airwaves on the last weekend of October (SSB) and November (CW) with the goal of making as many contacts with as many different DXCC entities and CQ Zones as possible.

Space Weather and Radio Propagation

I have updated my forecast on the expected propagation conditions during both the SSB and CW weekends of the 2017 CQ World-Wide DX Contest.  I will publish a new update for the CW weekend, when we get closer to that November weekend.

The link to the latest update is: http://cqnewsroom.blogspot.com/2017/10/cqww-dx-contest-propagation-update.html

Good luck!

In this episode of the Everything Ham Radio Podcast, we talk again with Ria Jairam, N2RJ. This time we are talking about the different JT Modes, JT65, JT9 and the new FT8!

We talk about its uses, how to operate and what you need to operate the different modes.

Check out the show notes to listen to the episode as well as get links to all the different things that we talk about at:

http://www.everythinghamradio.com/podcast/85

In this episode we talk about the Yaesu System Fusion DR-2X repeater, the upcoming Solar Eclipse and more.

There is some interesting new features on the DR-2X repeater over the DR-1X that came out a couple years ago, but there is also something that it doesn’t have. Some of these features, I wish that we had on our club repeater, but those features are not enough for us to go out and buy this version.

There are a lot of special event stations that are going to be on the air around August 21st this year when the full solar eclipse occurs. This is the first time since 1918 that a full solar eclipse has gone from one side of the US to the other. I unfortunately am to far south to the see the full eclipse, but I should get about a 75% one here in the DFW area.

We also talk about some other stuff, but you are going to have to check out the show notes and listen to the episode to find out what that is.

Last weekend, I was able to participate in the ARRL June VHF Contest, my favorite ham radio operating event. I thought conditions were pretty good…mostly I am satisfied if we have some decent sporadic-e propagation on 50 MHz, which we did. Once again, I entered in the Single Operator – 3 Band category with a claimed score of 34,969.

This is the first contest where I used WSJT modes and was successful but certainly not highly skilled. I know I blew a couple of MS144 contacts due to operator error on my part. As I prepared for the contest, I was really focused on getting the computer/radio connections sorted out in advance, which I did accomplish. I made some JT65 and MSK144 contacts a few days ahead of the contest, so I was good to go. The issue that I totally missed was thinking through the operating position so that I could switch modes/bands easily. Instead, I had lots of cable plugging and unplugging as I moved things around. More to learn and improve on next time.

K0NR Single Op - 3 Band
Band QSOs Mults
-------------------
 6:   254 110
 2:    29 10
 222:
 432:   3 1
-------------------
Total: 286 121
Total Score = 34,969

I made a dozen JT65 QSOs, all on the 6 meter band. These contacts were with very weak signals so I probably would have missed them on SSB. I have concluded that the main purpose of JT65 is to give bored operators something to fiddle with when band conditions are poor. It always seemed like there was just enough signal present for me to keep trying, sometimes with success, sometimes not.

I was very pleased to work K5QE for my first 2m meteor scatter QSO (MSK144). My intent is to spend more time with this mode in the coming year and focus on chasing grids on 2 meters.

I looked back at my previous scores in the 3-band category. My best score (48,117) was back in 2013, the first year there was a 3-band category. Looking back at my blog posting from that year, at the time I didn’t think the band conditions were very good. I also came across this article by W0VG which indicates that stations from Colorado scored pretty well that year compared to other parts of the country. The results article in QST for that contest provides more detail.

So maybe propagation wasn’t that great this year after all. At least not in Colorado. (The DX spotting map looked really good in the eastern side of the US.) But I’ll go back to my earlier statement that any June VHF contest with some decent sporadic-e propagation on 50 MHz is a win.

Thanks to everyone that came out and played radio on the VHF bands.
