We used a similar dual headphone feed technique. Instead of monitoring the
SCA for cueing we had a two way radio system and the other phone was fed
with the receiver output. The advantage of that was that the talent or
others could talk back to the studio without using the Marti to do it. Our
truck system ran on battery so instead of just leaving the Marti on during
breaks we could save the battery and use the two way for communication.
The use of DBX for this kind of thing is still a valid method. I had lots of
experience with Dolby SR as we used it on our cart system at WLTW in the
early nineties. If anybody has a couple of channels of SR it would make a
great STL or Marti RPU noise reduction system offering about 25 dB of
enhanced dynamic range.
See you at NAB!

At one time Marti in Cleburne offered an optional noise reduction system
vailable for their 150-161, 450-455 mHz. and the 67 kHz. and 92 kHz. SCA
Systems.
I worked for a station where the CE was very keen on the use of DBX noise
reduction on the two Marti sysytems we used. The noise reduction reduced
the hiss and noise noise and made a real difference in the sound and the
reduction of the hiss got rid of the rising noises between pauses caused by
both the Marti's built-in compression and the stations compression. The DBX
was very specifics about input level sho we used a Shure Remote Amp driving
the DBX the DBX was set to feed the MArti below its processing threshold.
All operators we urged to not over drive the Shure as it would affect the
noise.
We also used a dual monitoring headphones at the remote sites, split
headphones with one side off air if available, the other side with the 67
or 92 kHz. SCA from our FM station that could be switched to any of three of
the stations final audio to the transmitter with built-in ducking IFB from
the talkback microphone in the control room.
On any shows involveing remote telephone calls the talent at the remote
could hear the producer's cue, "..next call from Mike downtown.." then the
talent would hear the call over the SCA channel. The air signals were all
pre-delay for the talent.
I agree I have heard many Marti remotes that had fantastic quality. In my
ealry days in AM three of my stations actually played records and carts from
the back of a van or a portable console back to the studios via a Marti and
the quality was more than acceptable. If it was worse than a 5 kHz. phone
line I would allow them to use the Marti's.
It will be interesting as more RF digital bi-directional interconnects
become available to be used in the existing RPU bands and other bands in the
future.

We had DBX Type 2 encoding on all marti shots. That, along with the
occasional 100W shot really helped. Trucks had dual 10 db antennas, studio
had 13 db antennas, and tower sites had 15' omni poles (dunno actual gain).
No show was put on the air with less than '100%', about 100 mV. In a couple
of instances, we wound up two hopping (eight freqs helped) or running the
signal through an EQ to make it sound better (not much you can do about the
hiss)

Shake hands. I say Hogwash. Program your station correctly with good
content
and you'll win. End of discussion. If there's a cash flow problem then have
management fix it by upping the rates or getting the sales people off their
b
utts. Now, do you really want me to tell you what I think? :) Steve

Steve, there is validity to getting out there, rubbing elbows with the
public
and hanging banners. You would be hard pressed to convince me that these
thing
s don't help with the image of the station. Have the studio announcer push
th
e fact that the remote crew is at site "A" and why you should go there. Then
gi
ve the "remote" announcer a PA mic. Don't crap up your air signal with some
noi
sy assed marti signal. Jeff Glass Northern Illinois University DEC
