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.

Europe
By Georg Wiessala
Longwave broadcasting seems to be a relic from radio’s

shortsighted decision—losing an important channel for media diplomacy and
international communications abroad.”

Find out why he says these antennas are, “worth the cost, considering the
practicality they provide.”
DRM—Digital Radio Mondiale Spectrum within a Spectrum
By John Piliounis SV1OCS
Digital Radio Mondiale (DRM) has been around since 1998 and
has slowly found acceptance on HF as well as the FM band. But, the lack of
affordable, capable receivers has hampered its success. 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.
Results of FCC Incentive Auction and Repacking of US TV
Spectrum
By Mike Kohl
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
