Keeping the Ships Moving on Canada’s Welland Canal

By Ron Walsh VE3GO

Radio communications plays a vital role as up to 32 vessels each day navigate Canada’s Welland Canal. And, with over 24 miles of locks, routing each one through in 11 hours is a study in efficiency.

TSM Maritime Monitoring columnist, Ron Walsh, get a rare inside view.

By Danny Oglethorpe

With the FCC’s spectrum auction and TV-band repacking looming, is Over-the-Air TV DX still possible? The answer is, “Yes!” according to long-time TV and FM DXer, Danny Oglethorpe, who has logged more than 1,100 TV stations since the 1960s.

Add CW and SSB to Your Portable SW Receiver the Easy Way

By Richard Fisher KI6SN

One of the serious shortcomings of a large portion of portable, multi-band shortwave receivers and many vintage shortwave radios is their inability to decipher SSB or CW signals. For some SWLers it isn’t that big of a deal. For others, it can put a real damper on the enjoyment of the full spectrum the radio covers. But, there’s a way to add an outboard BFO to any radio on which you would like to copy CW or SSB signals. Richards shows us how.

By Cory GB Sickles WA3UVV

After using digital voice for an extended period of time, most find analog FM to be “muddy,” “noisy,” and of a lower quality than they previously thought. And, whether you find favor with DMR, D-STAR, NXDN, P25 or System Fusion, Cory urges you to try digital voice for yourself and see what you think, after using it regularly for a few weeks. He believes you’ll be amazed at how your perceptions change. Cory also takes a peek at Yaesu’s new digital 2-meter/70-cm 50-watt mobile transceiver and scanning receiver.
