Amateur Radio Station WA2FNQ
Almost 10 Years Later
July 1999
Pictues with detailed descriptions.
This is the studio in the summer of 1999, almost 10 years later.
While all of the original equipment is still here much has been added to the
design. Audio editing is now done by computer instead of tape. Final assembly
of video product is also now computer assisted. A Crown D-75A and 3 rear
channel speakers have been added to the monitor system. The audio mixing
console is still the original. A Radio Shack 5 channel stereo mixer was used
as the foundation. It was modified and expanded out to 10 channels by the
addition of a submixer panel. The transmitters in the next room are controled
by a switch box to the rigth of the audio console.
The picture on the left shows the equipment rack containing the
studios main audio/video equipment, switching and patching. Most of the audio
processing is done by a pair of dbx 163X compressor/limiters. A very modified
Shure Level-Loc is used for additional audio processing where needed. Audio for
the stations FM transmitters comes from an Altec 1589B mixer/amplifier. A dbx
NX-40 is used for audio tape noise reduction. Audio follow video switching is
done with a 12X push-button panel.
The picture on the right is the original computer work station area.
An original Compaq portable is used for working packet and RTTY with an old
MFJ 1278 multi-mode data controller. An ICOM IC-745 has been added for
SSB/FM/CW HF operation. It drives an SB-200 linear in the transmitter room.
To the right is a new work station area. The Compaq laptop is used for general
work as well as APRS and other packet operation. The audio mixer can provide
another 6 channels of stereo inputs in the studio if needed. This was the
main mixer in the old studio. The PPM panel is used to monitor the additional
audio channels. A Leitch FR-662 frame houses video distribution amplifiers
used to adjust levels and equalization where needed.
There has been a lot of "stuff" added to studio B over the years.
While not totally operational as a system, most of the equipment here does
function. Studio B has been used to do audio/video editing while the main
studio was tied up with other work. Equipment may patched to the main studio
via tie lines for use there.
More Additions - December 1999
This is the computer workstation in studio B. It is used for editing
small audio files, working with new software or just plain, boaring word processing.
This workstation is used to do digital editing of large audio files,
processing of picture files and non-linear video editing. Audio files are generated here or brought in from studio A.
After editing is completed, the files can be made in to an audio CD. This is also where the
pictures and HTML for this Web site are done.
