We finally tested the interference environment around BITS using a TV Yagi antenna. This was at 3 pm on Monday 13th November, 2006.
The frequency region around 60-70 MHz appeared the most calm of all, particularly 61-62 MHz. We need about 500 KHz bandwidth, and we will keep it on 61 MHz. The band at 120-130 MHz appeared to be good as well. It is possible to utilize the same antenna and receiver system at 122 MHz as well, just in case there was intermittent terrestrial source at 61 MHz.
