Team W4AAW Totally Remote Multi-Multi Contesting by Rowland Archer, K4XD
How in the world did a M/M contest station deliver a top ten finish with no operators in the shack? Team W4AAW has taken remote operation to the next level ? fully automated M/M contesting. There?s even a zero-cost client option. We?ll explain how we did this, give you a taste of what it?s like to operate a M/M station remotely, and tell how you can join us in exploring this new frontier in amateur radio contesting.

Design Issues for a VHF-UHF Solid State Power Amplifier, with Carl Luetzelschwab K9LA
Carl K9LA will deviate from his usual presentations on propagation and solar topics to discuss design issues for a 50 Watt VHF-UHF solid state RF power amplifier. This is not a construction project, but rather a presentation of notes gathered from his 41-year career as an RF design engineer for Motorola and Raytheon.

W4AAW is configured as a Multi-Multi station for Totally Remote Multi-Multi Contesting. Our group of operators, known as TeamW4AAW developed the interfaces and systems to permit Totally Remote M/M Contesting. TeamW4AAW was the first to employ the concept, mounting the first Totally Remote CW, SSB AND RTTY M/M contest efforts.
All W4AAW operating positions can be fully remote-controlled through a low latency Internet connection.
One position is dedicated to use by operators with a K3/RemoteRig set up. The other positions may be accessed by TeamW4AAW members without their having to buy any special hardware or software.
The station has an automatic antenna switching system from Top Ten Devices, Dunestar bandpass filters at each position and coaxial harmonic stubs (W2VJN design) as required.
The screen a remote amateur sees is as high resolution as would be seen in the shack. The audio heard at the remote position is crystal clear. The SSB audio quality gets comments constantly, such, “I would never know you were operating remote, if you had not told me.” The latency is extremely low, equal roughly to the length of one Morse “dit” at 30 wpm. High speed CW operation is well accommodated with some team members chalking up 180 to 200 QSOs/hr rates.
The ARRL described our team as….”a group of more than 20 operators, [that] helps to maintain and operate the station, which has become a real-world laboratory in the to-date niche field of remotely controlled contesting.”
TeamW4AAW members operate the station remotely from their own QTHs in New Hampshire, Pennsylvania, Delaware, Virginia, North Carolina, Georgia and Missouri. Members outside the continental USA include those in Panama, Greece, Hungary and Germany.
To be clear, W4AAW is NOT a “station for rent” facility. TeamW4AAW members pay no dues. They do, from time to time, share station costs, lend or otherwise supply equipment and pitch in with their own unique and considerable expertises.
The Remote Contesting Project was begun to create a cost-free or low-cost way for accomplished, serious Contest Operators who may have no access to a competitive station, to operate one. Some of our accomplished contest operators live in HOA-restricted neighborhoods, apartment buildings or in homes where anything more than wire antennas would be impossible to erect.
We assiduously adhere to all FCC rules and to the rules of any contest we enter.
We are continuing to improve our Remote Contesting setup and look forward to working you in the next big contest.
