Playing RTTY radio

Spent a couple hours yesterday afternoon out at the club communications trailer for the ARRL Rookie Roundup (RTTY). Tom (AJ4UQ) set up one of the club radios, a Yaesu 897D and one of the laptops to run RTTY.

There were two other rookies that came out, James (KK4REM) and Andrew (KF7YOX). We operated using my call sign this year and after Tom showed us the basics and helped set up some macros in fldigi, we were off and running.

The radios and laptop were initially set up to run off the batteries in the trailer, but after a few minutes, we noticed the voltages displayed by the radio were getting pretty low. A quick look revealed the batteries had gone dry for some reason despite having been topped up a couple of weeks ago. They were also unusually hot even after they were refilled with water. Some of the more knowledgable people suspected a problem with the charger not reducing the power once the batteries were charged. We managed to find a long extension cord and switched over to wall power.

This highlighted another purpose for these “contests”: it gives you a chance to exercise your equipment and discover problems, especially important for something intended to be used in emergency/public communications purposes.

After getting past that, we started hunting around the bands looking for other people playing in the Rookie Roundup. We wandered around several bands, learned how to adjust and tune the antenna (a Little Tarheel) and a bit about how to use the radio. We found a few people and made a handful of contacts, but it seemed like it was easier to hear them than to make contact with them. We decided that maybe the antenna didn’t have a good enough ground plane, and Tom thought that maybe some radials would help. That’ll be something else to try for later.

I think in the 3 hours or so that we were operating, we made about 5 or 6 contacts. More importantly, I think the three of us learned a little more about radio operating. I learned a little more about the inner workings of the trailer and a little more about the different digital modes. We got to hear several different types of digital modes, including some PSK signals.

Overall, even though we didn’t make a lot of contacts, I think it was still a pretty good time. Got outside to play radio, worked with a couple of the newer hams, all great fun.

Now I want to see if I can build my own interface so I can do digital modes at home.

ARRL Rookie Roundup (RTTY)

Coming up this weekend (Aug 18) is the ARRL Rookie Roundup (RTTY) which I’m planning on participating in. Like last year, we’ll be using the club’s communications trailer and setting up at the old fire station off Dorchester Road (6938 Dorchester Rd) by the Air Force base.

Not sure who’s call sign we’ll be using yet but hopefully the bands will be in decent shape and we’ll be able to make some contacts.

I’m in QST!

Well, the back of me is in QST anyway. If you flip to page 82 of the latest (August 2013) issue of QST magazine, the bottom half of the page talks about the upcoming August Rookie Roundup (RTTY) contest.

Last year I got to participate in it with a few other people from the club. The accompanying photo, taken by Tom (AJ4UQ), is of me and fellow rookie Warren (KK4EVI) trying to make sense of what the software was telling us.

The only problem with the photo is the caption is incorrect, and gives the wrong call sign (and therefore name) for me and Tom. Here’s what the image caption should read

The red bandage around my arm is from donating platelets earlier that day.

It was fun participating in the roundup last year, and I got a good introduction to the digital modes, including packet radio and even sending email using the radio. I hope we’ll be able to do it again for this year’s Rookie Roundup (August 18, 2013).

Field Day 2013 Part 2

Decent weather, no rain and partly overcast skies kept Field Day today from being too sweltering hot and made operating tolerable. Spent the bulk of today logging, and got on the radio for the last hour of Field Day to make a few more contacts. The club managed to get a little over 500 contacts on the SSB station and I think about 80 or so CW contacts.

I was even hearing a little bit of activity on 6m through my HT, which is something I practically never hear around here. I couldn’t make out much of anything, but I was able to tell that it was Field Day activity. No idea where it was coming from though.

Having a little more radio experience under my belt made this Field Day a more enjoyable experience than last year (not that I didn’t have a good time last year). Knowing a little more about what’s going on really helps and I feel like I was able to make more of a contribution this year.

Looking forward to Field Day next year.

Field Day 2013 Part 1

Had a most excellent time at Field Day yesterday on board the USS Yorktown with CARS. I was put in charge of IT, which meant setting up the two laptops and a little local wifi network so that they could communicate and share a log file.

At 1800UTC (2PM EDT), the chaos the activity started. I spent the first few hours in seek and pounce mode (S&P), tuning around 40m at first and then moving up to 20 and then 15m. Was able to rack up a bunch of contacts, but it wasn’t easy. Thunderstorms to the southwest and in Georgia were causing static crashes because of the lightning. I’d be trying to work some strong stations, then 20-30db of noise would just wipe everything out on the frequency for a second or two. That went on for a few more hours, and then the rest of the evening was relatively clear. Then the problem went back to trying to pick out the Field Day exchange with neighbouring stations or groups of Boy Scouts stomping by behind us drowning everything out (the usual chaos).

I stayed on the Yorktown until around 10ish. A few other club members operated and got some pile ups going. I spent some time hanging out at the CW and digital station, taking photos and helping out with the logging on the phone station.

Field Day on the Yorktown offers a great view of the harbour and the Charleston penninsula while we’re operating.

This is the CW and digital station in action. Last year the CW station was set up in the club communications trailer out on the pier, but didn’t work out so well there, so it was brought up to the ship this time. The digital station was having a similar problem with noisy bands that we were having on the phone station so I don’t think there were too many contacts being made there.

Back for more Field Day fun today until 1800Z (2PM EDT) and then breaking everything down.

If you’re on the air for Field Day today, listen out for WA4USN. It might be me that’s operating!
