This repeater is
located in downtown Towson,
MD. Input is NTSC on 434 mhz. or DVB-T
video on 439.25 mzh. Output is on 421.25 mhz. NTSC (analog)
video). If you are close-in to the Towson area, an analog-capable
television on cable channel 57 -AND- connected to a separate antenna
will enable viewing. A second output of FM
television format is on 1.291 ghz. Scientific
receivers are an inexpensive
and quick way to view the repeater output in high quality.
We have a small
supply of these devices for sale at $10 each. They are
pre-programmed for our repeater. For farther away viewers, a
pre-amplifier is needed. The repeater features receiving
antennas on both
the north and south sides of the building. Investigation is
underway to add DBV-T output. The Towson ATV repeater is live from 9:00 am. to midnight daily. Picture #1 is the repeater ID.

web stream to the British amateur television
club (BATC) website
The Towson W3BAB
output is streamed to the British
Amateur Television Club (BATC) website. On the left side is Open
Broadcast Studio software (OBS). The first callsign
image in the picture is displaying repeater output of Ken K3UQQ's
off-the-air via a Scientific Atlanta 9660 Receiver. The identical
image to the right is Ken's callsign signal
selected to be passed to the BATC website by Internet stream.
The picture on the right is the BATC webpage showing the
famous CATS logo. Audio is captured by
an ICOM HT tuned to 2-meters.
BATC via HTML5, the
delay on this stream is 25-30 seconds; an industry norm where the HTML5
protocol is used in place of the now obsolete and disabled Adobe
product. A recent effective alternative is to view
the stream via the free VLC
software. Run VLC and press
CNTL-N to "play" this video source: rtmp://rtmp.batc.org.uk/live/w3bab
. Follow with selecting PLAY. Streaming delays should be well
under 10 seconds. A big thank you to John KA3ZTC for
receiving the Towson ATV repeater output and 2-meter audio for
streaming to the BATC facility and
for their support in this venture.
