Hello LF Gang,
Since my original review of "The First" Ropex transmitter has been
quoted on this reflector, let me add a few comments:

a) our unit actually produces 170 watts rather than the 130 watts
advertised,
b) our unit has been used 24/7 for the past two years as a beacon, (now
QRSS) and has never failed,
c) its output circuit protection scheme works flawlessly,
d) the output waveform is excellent,
e) my negative comments (about crystal changing, etc.) still apply when
it comes to trying to change the Ropex' operating frequency. As a beacon
though, on a fixed frequency, it is perfect and has been a very good
investment.
