TSM Reviews: QRP Labs Ultimate 3S Transmitter Kit
By Mark Haverstock K8MSH

It’s the old radio conundrum: Is the band dead or is it that no one is listening? This month Mark looks at a beacon transmitter kit that lets you see just how active the band really is. The QRP Labs Ultimate 3S transmitter uses Weak Signal Propagation Reporter (WSPR) Frequency Shift-Keying (FSK) transmissions in beacon mode that can be received by receivers around the world set up to send back reports on a central reporting site on the Web. Mark puts this kit through its paces.

By Georg Wiessala
Longwave broadcasting seems to be a relic from radio’s infancy. While its future is uncertain, during an era of Internet streaming and satellite beaming, it continues to hang on.

Joe wanted to see how well DX Engineering’s DXE-TW-2010-P 20 through 10 meters portable antenna would work—given his QTH. Find out why he says these antennas are, “worth the cost, considering the practicality they provide.”

John Piliounis takes a look at the technical side of this open-sourced, international digital radio format that can coexist with analog signals broadcast from the same tower.

The results are in from the FCC’s massive TV band incentive auction and now the 39-month process begins in which some stations will go off the air; others will go off the air but join another station in the market to show up on a sub-channel, while others will move from UHF to VHF TV band.
