The UARC ATV Repeater is once again carrying
NASA coverage of the space shuttle mission
UARC is pleased to announce that NASA coverage is once again available via the Farnsworth Peak ATV repeater. This coverage may be seen with a standard cable-ready TV or VCR connected to an outdoor antenna (a true 70cm yagi is much preferred over a standard VHF/UHF TV antenna) and tuned to channel 58 with the TV/VCR set to cable mode. (If you tune to channel 58 and just get spanish-language TV, you have not put it in cable mode!)
Important notice: Due to on-site interference (on the mountaintop) the NASA feed may be unavailable at times. While we try to avoid such outages, the extremely high RF radiation levels at this site make it difficult to anticipate all possible problems in advance.
How to receive the repeater's signal
Here are a number of articles about how one receives the signal from the repeater:
The ATV repeater has been configured such that it is possible for someone with a 70cm receiver (such as a mobile rig, HT, or scanner) can hear the space shuttle audio. These signals are transmitting continuously during a mission and unless someone is speaking or there is a program being presented, there may be no audio at all.

M2 M-Squared antenna systems has a lot of antennas, HF through 23cm.
MiniCircuits Laboratories Mixers, MMICS, VCOs, etc. (Yes, they sell directly to the experimenter... I think... Let me know if you know otherwise.)
SHF Microwave A good place to go for Gunn transceivers and other microwave components
SSB Electronics Equipment for 50 MHz through 47 GHz!
RFHam Another source for VHF/UHF/Microwave gear.
Making your own stuff to use on ATV:
Most of these articles have to do with building antennas. While antennas are simple to build, there are a few things to keep in mind:
- When an antenna design calls for the use of a nonmetallic boom or a metallic boom, DO AS THE INSTRUCTIONS SAY! If you use a boom different from what is called for the performance of the antenna will suffer unless critical dimensions are appropriately altered!
- Always use the size or diameter of metal rod or wire called for use as elements in the antenna construction plans. The use of a size different from what is called for will require recalculation of these element sizes to avoid performance degradation.
In other words: Be very careful if you substitute materials when constructing your antenna. If you are going to the trouble to build an antenna, then it makes sense to obtain those materials called for. If you are having trouble finding some of these materials, then look at other designs that might use materials that you can get.
