WA4USN Rookie Roundup 2015

CARS has set up an operating day at the club station, WA4USN, on board the USS Yorktown for this year’s ARRL Rookie Roundup (SSB). For Rookie Roundup purposes, a Rookie is someone who was licensed in the current year, or within the past 2 years (2013, 2014, or 2015). If you’re a rookie or new ham and want to experience the HF side of amateur radio or just want to operate from the club station (it’s a pretty neat place to play radio from), this is your chance!

The club room will be open starting at 1PM, April 19. Rookie Roundup starts at 2PM EDT and goes to 759PM EDT (1800 – 2359 UTC). If you’re interested, drop me a note and I’ll put you in touch with the proper people.

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).

Learning about digital ham radio

Yesterday was one of ARRL‘s Rookie Roundup contests, so some of the CARS members organized a rookie radio day to show off some of the digital amateur radio modes.

The idea is pretty simple. Instead of piping the audio output of the radio signal to speakers, it’s sent to a computer (with some intervening hardware) where the digital signals are decoded and displayed by software. The computer’s sound card generates audio tones that are sent to the radio for broadcasting and for other computers to decode. Everything is handled through the computer and software (fldigi in this case) using pre-programmed F-key macros (manual typing works too) except for changing radio frequencies (with the right set-up, even that can be done on the computer). Pretty neat stuff.

There were three of us rookies around and we all got to play digital RTTY (radio teletype) radio, sending out calls, responding to other operators and learning how to use the software. I think we made a total of 6 contacts, which isn’t huge but there might have been some power and/or antenna problems. It was still a good learning experience.

Another member set up a battery powered radio with a 40m dipole antenna and demonstrated sending emails over the radio via Winlink, another pretty cool amateur radio service. Find a reachable Winlink server to broadcast to, compose your message and the software sends the appropriate signals to the radio (via intervening modem) to the listening server, which in turn sends out the emails over the Internet. You can also download any received emails stored up for you. Using this method, even if you’re out of power, have no other form of internet access, or are in some other kind of emergency communication mode, you can still send out emails to other people as long as you can reach a server with your radio. Pretty awesome stuff. The data rate is pretty slow, but you can still get communications out.

It was a fun three hours we spent playing radio, and a good introduction to digital radio. Makes me want to do more
