ENGINEERING NOTE BOOK CHAPTER 28 (Here for earlier chapters) This is the current Problem Of the Day (POD) It's a Blog - Read from the bottom up... 159. 2008-07-22 SETI Net Gains 180 degrees I went together with my neighbor to remove some tall pines that were blocking the northern view of the antenna. Up till now I only could look in what I call the South View which is 90 Degrees (due east) to 270 degrees (west). With them gone I gain two additional views: East (0 to 180 degrees) and North (270 to 90 degrees). This will make a huge difference in the area SETI Net can cover . When I want to change from South View to North View , East View , or West View I have to loosen a bolt and push the antenna around to the new location. Not to difficult.
That strange coverage area is due to the distortion caused by the Mercator projection of the Sky Map 158. 2008-07-19 to present Small Radio Telescope (SRT) My astronomy club (San Diego Astronomy Association) asked me to see if I could resurrect a radio telescope that was donated to the club some years ago. I readily agreed and finally am able to start on this interesting project. First part of the project is to identify what I have. Some pictures from the SDAA_RASIG Yahoo group site and my own photos of the dish at The Dark Site.
This is the horn, and receiver (in the silver box)
Receiver - Cover off The horn has what appears to be a choke added to a commercial feed so that it will operate at L-Band (1420 MHz). The L-Band feed is a probe ( 40 mm long) that lays along side the white C-Band feed cover
