#1: WLFL-TV Fox 22 to broadcast RARS SAREX CONTACT LIVE!
That's right -- Fox 22 will be set up at Cary High School to make a LIVE
broadcast of our SAREX contact from that location. Depending on timing, we
will pre-empt Romper Room or the Jetsons!
Thanks, Fox 22!!!

#2 "NASA SELECT" ON AMATEUR TV DURING NEXT WEEK'S SHUTTLE MISSION
A special Amateur TV transmitter set-up at NC State will be transmitting
"NASA Select TV" during most of the space shuttle's mission next week.
AEA has loaned us their ATV transmitter/mast mounted amplifier combo. That
will give us 50 big watts. The Center for Communications at MCNC will
receive the downlink from the satellite, and use their microwave links to
route the signal to the roof of the D.H. Hill library building at NC Stage.
We'll take a feed at that point. MCNC will also transmit the signal on an
instructional TV band to be received at the schools involved in SAREX.
The transmitter will feed a VERTICALLY POLARIZED antenna temporarily
mounted on the D.H. Hill roof.
The video carrier frequency is 439.25 MHz., and YOU CAN RECEIVE IT WITH ANY
CABLE-READY TV (and a good antenna). Here's how...
Connect a very good UHF antenna, pointed at NC State, to the VHF input of
your cable-ready TV. That's the VHF input -- not the UHF input. ALL
"cable-channel" signals come in the VHF antenna port!
Make sure the set is in the CABLE mode. Some sets call it "Antenna:
TV-CABLE" or some such consumer-oriented confusion. Then tune the set to
channel 60. That's CABLE 60, not UHF channel 60!
Guess what actual frequency Cable channel 60 is....? That's right:
439.25! Right where our ATV will be.
Now, most TV stations transmit with a million-plus watts ERP to your
pathetic rabbit ears or bent UHF loop. We're gonna have maybe a hundred
watts ERP. Will you be able to see it? Hey, that's the exciting part. At
any distance from DH Hill, you will need a good antenna -- VERTICALLY
POLARIZED (most ATV is horizontal, but we need to keep our installation
simple, and a vertical is easiest).
The signal should come up Monday, but maybe earlier over the weekend, and
run most of the week. Let us know if you can see it!
Note: it is illegal for Amateurs (including ATV) to retransmit other
services. The FCC has issued a special waiver, and we are permitted to
retransmit the NASA Select video.
Happy Viewing.
