Tri-PTC Sprint Tri-Athlon Amateurs Needed

CALLING ALL HAMS – FIRST CALL

We need your help to provide race support on Saturday, August 19, 2017 from 0645-1000 for the 2017 Tri-PTC Sprint Triathlon.

This is the first and original triathlon which, after a brief change to Lake McIntosh, is back on the original course starting/finishing at PTC City Hall / Lake Peachtree.  We first supported this race back in 2002 and have provided support every year since.  This is the “short course” race 1/3 mile swim, 13 mile bike, 5K – not to be confused with the spring race PIT “long course”.

The link with all the race info is:

Here’s what we need:

BIKE

Bike 1 Hilltop Dr & Hip Pocket Rd (N)

Bike 2 Cedar Dr & Hip Pocket Rd (S)

Bike 3 McIntosh Tr & Skiff Trace

Bike 4 McIntosh Tr & Shadowwood

Bike 5 Robinson Rd & Camp Creek Tr.

Bike 6 Robinson Rd & Crestwood Dr

Bike 7 Robinson Rd & Braelinn Rd

Bike 8 Colonnade Dr & Columns Ln (S)

Bike Rover (motorcycle mobile) – AC4MG, Matt Gonter (XL)

Bike Sag Truck (need mag mount) – W4MEZ, Joe Mezzatesta (L)

OPERATIONS

Race Director Shadow – KI4HHI, Mary Catherine (M)

PD/FD Liaison –

Net Control 1 – KI4ASK, Joe (L)

Net Control 2 –

Transition / Swim –

As you can see, we need a lot of help!

The race starts at 0700, Saturday morning, August 19, 2017. We are generally done by 1000.  We’ll run this the same way we have in year’s past.  I’ll send more detailed instructions as we get closer to race day.

Our mission is to support the event organizers by providing timely communication from different locations on the race course. We help ensure the safety of ALL participants.

You do not have to be a member of ARES or even a club member to help. All you need is a Technician (or higher) license and a desire to get involved.

All Ham operators need to be on-station by 0645. At that time, we will have a check in. We will use the 442.500 Peachtree City repeater linked to 145.210 and 146.535 simplex. This should give us more than adequate coverage.

If you can help, please let me know. I also need to know what size of shirt you want (S, M, L, or XL).  If you have a preferred duty station, let me know.

Please consider donating a few hours of your time to support this fun event.

Thanks and 73,

July 2017 Second Sunday Reminder

WSPR on Raspberry Pi & QRP Filter

Project Description

There are a several options for this session:

  1. Build a QRP Filter (Low Pass Filter, specifically, one of these)

  2. Setup a Raspberry Pi for WSPR transmission, using the QRP Filter to enhance the TX.

WARNING: This project has the potential to damage your Pi. Though we’ll take great precautions to prevent that, I recommend using one of your older Pis or one you’re okay with potentially frying. The project involves connecting the clock pin directly to an antenna, which has the potential for feedback current above what it can handle. We’ll use a Schottky Diode on that pin to try avoiding that.

  1. As usual, you are welcome to just come hang out and get to know some fellow hams.

Cost

To recoup the cost of the components, we ask for a $5 donation if you build a QRP Filter. You can just bring cash to the event or pay via PayPal.

What to Bring

Project 1 – Filter Only (20m or 30m): No need to bring anything, I’ll have a couple of soldering irons and solder as well as the kit. You’re welcome to bring your own iron, solder, and if you do, something to set down under your work area (cardboard or silicon mat). That does tend to speed the build up a bit.

Project 2 – Bring a Raspberry Pi, preferably older or that you’re okay with potentially damaging (see warning above). Also, you’ll need to be able to SSH into it, so it needs to be a WiFi capable Pi or one that has an Ethernet port. (edit) Or have a display and keyboard for direct commands. Also, don’t forget your SD Card to run the OS. I’ll have an image with WsprryPi already loaded, as well as the WiFi password.

NOTE: TXing on 30m requires a General license or above, however, the WSPR range on 20m is within the range for Technician level.

If you don’t have a Pi, you can purchase one locally at MicroCenter or online from many different retailers, including Amazon.

Hope to see you there!

P.S. We’ll also be conducting a FREE license testing session from 12 PM until 2 PM, just before the tech session, same room. So if you’ve been meaning to get that test out of the way, this is also a good opportunity for that as well.

2:00 PM at PDK – see you there!

July Member Meeting – QRP by AA4BW (Update)

About our program:

Our speaker this month, Steve Hudson, AA4BW, will be talking to us about the fun of operating QRP.

QRP is generally defined as an output of five watts or less, and Steve will be sharing some of his experiences gained from operating for many years a 5 watts or less – often a lot less! In fact, Steve typically runs just a couple of watts out, but even with such a miniscule amount of power going to the antenna he has had thousands of enjoyable contacts (including many extended ragchews) with stations all over the world.

Steve’s program will take a brief look at the technical side of things to see just exactly what it means, in terms of dB, to give it a try with low power. But mostly he will talk about the operating side of things with a focus on just how much fun going QRP can be. He will discuss the on-the-air techniques and equipment used by QRP operators, and he will have a number of QRP rigs on hand for you to see. He will also share a look at his recent experience operating QRP from the Republic of Palau (as T88BW) and from the island of Yap in the Federated States of Micronesia (as V63BW), both in the western Pacific. In addition, he will talk about his experiences with QRPp, or “milliwatting,” with output levels that measure well below the 1-watt mark on the wattmeter!

First licensed as WN4JXO in 1968, Steve has been an active ham ever since. He holds an Amateur Extra Class license. He particularly enjoys CW, and he also enjoys homebrewing (particularly QRP rigs). Lately, he’s been having fun carrying small QRP rigs and portable antennas with him as he hikes and fly fishes in northern Georgia.

A journalist by profession, Steve is founder and CEO of Chattahoochee Media Group, a publisher of outdoor books, and also teaches journalism at Georgia State University. He is the author of numerous magazine and newspaper articles and more than 20 books. Currently he’s putting the finishing touches on a new book, “QRP 101,” a practical and hands-on guide to discovering the fun of QRP operation. It should be published this summer.

Steve and his wife Ann live in Alpharetta. He has three grown children, two grandkids, a cat named Zoe, and a miniature Schnauzer named Ellie.
