I've had a ten meter beacon, on and off for the last 20 years.
Both beacons are located at my home qth (Burlington, Ontario), which is high up on the side of the Niagara Escarpment, (a stones throw south of the town of Waterdown, Ontario). My view of the west end of Lake Ontario and around the Golden Horseshoe is quite amazing and I can easily see Niagara Falls from my backyard, which is about 80 km's away.
My ten meter beacon is simple, like most. I've use a Radio Shack HTX-100 10 meter transceiver, a 30 amp Alinco power supply, and a keyer device designed and made by Hugh, VA3TO. Hugh programmed the CW message into the units eprom many years ago and when 12 volts is applied, the message is sent out and repeated continuously. Originally I had planned on using a memory keyer for the message function, but found memory keyers were too costly so I went with Hugh's design. Hugh no longer builds or sells these beacon ID units, however, he has a circuit design and programming instructions available on his web site.....www.va3to.com. For antennas, I've used an off-center-fed dipole or Windom antenna, ten meter dipoles, sloping dipoles and verticals. At the moment I'm using the Solarcon A-99 vertical. The HTX-100 is set to about 2 watts.
VA3SRC on 12 meters uses the TS-50 and a ground mounted vertical antenna. I use the same ID unit on both beacons so they key up at the same time.
