And in a related story…..Laser Comm is teaming up with Auto Comm Ltd. of Palo Alto California to market to the Amateur radio Community the new Auto-Q radio package.

This new "radio station in a box" will utilize the best of Laser Comms new antenna system together with a completely stand alone Ham radio transmitter which will utilize the latest in a new digital technology called FT-8. The complete radio package is contained in a box less than 1 sq. foot and runs on the latest Elon Musk battery packs. These radios will make fully automated QSOs, and with a cell internet connection will upload all QSOs to the users DXCC and WAS. Head of computer development at Auto Comm. Jim Q Contact said “the new Auto QSO radio package can be deployed anywhere in the world. It can be set up at very rare DXCC countries, wanted counties or states and be left to run for months to make QSOs”. For those Hams that need a new country that has been difficult to get, they can deploy one of our units and then go home to their base QTH and work the Auto-Q Unit.”

Early testing has shown that the unit has been able to make over 2,000 QSO’s per month while left unattended. The Li-Ion batteries have a long life because of the very efficient radiation from the Laser Comm antenna. There has been some skepticism in the Ham community about the need for a ground radial system, but Auto Comm has done extensive field testing to proven that their antenna can radiate even better than a dipole at 300 feet.

When asked about the concern in the Ham community about un-attended QSOs being used for ARRL awards, Jim Contact said “our studies have shown that Hams these days are far too busy to spend the time at their radios to make QSOs. In todays society there are too many other demands on our time than to be stuck sitting at the radio using the old modes. Times have changed, and our studies have shown that today most Hams are more concerned about just getting the award counters rather than spending time trying to copy signals using the old outdated CW and SSB modes."

Auto-Q will have a table setup beside Laser Comm at Dayton this year so that customers don't need to walk too far through the mud.
