KEXP on satellite

If you are going to miss KEXP on KXOT 91.7, and don't have a high speed connection or don't want to tie up a computer streaming KEXP, you should know that it is available for free on satellite. On Galaxy 10, Ku Band transponder 6, 11805.0 Horizontal, UW TV, The Research Channel and KEXP share a digital DVB signal. Technically, it uses a symbol rate of 4.850 and an FEC of 3/4. Galaxy 10 is located high in the sky at 123 degrees west. Here in Seattle your azimuth should be 180.9 (basically due south) and an elevation of 35.3. It is located next to Echostar 9, a dish network satellite, if that helps anybody. There are three "virtual channels" inside of this digital signal, and KEXP is #3. It is not scrambled, but you will need some type of digital receiver.

I have never used any type of DirecTV or Primestar or other home DBS receiver, and I don't know if the symbol rate or FEC can be set on these. I do know that a commercial receiver such as a Scientific Atlanta PowerVU can be tuned to this signal, and there is a prosumer receiver out there made by Pansat which can probably tune this in as well.

This might be a worthwile experiment for somebody who has one of those old Primestar systems still sitting around or maybe there is somebody who wants to reposition a working DBS system to try this.

Here are some valuable links:

Incidentally, this is how KEXP is getting the signal to KXOT (you will notice a bit of satellite delay if you listen to the two signals at the same time). I confirmed this with a KEXP engineer when KXOT first went on the air. Backup is an ISDN line, if I remember correctly. This signal was on satellite well before KXOT came on, and I can only assume that it will continue after KXOT is shut down.

An old Primestar reciever or DISH/DirecTV receiver won't work unfortunately, since these are set to specific frequencies and symbol rates, plus a primestar reciever is set to only recieve signals encoded in DigiCipher 1. However, as Marge said, any prosumer FTA (Free To Air) receiver will work. 4DTV receivers may also be setup to receive the signal (check the documentation first). You may also find some receivers at a thrift shop like Value Village or Goodwill, that can be had for between $10-$20. Most receivers caplable of receiving the signal will have the DVB logo on it.

There are also PC-based DVB FTA satellite receivers available, that you can stick into an open PCI slot on your computer. Although this will still tie up a computer, it won't require an internet connection or phone line. These are available from manufacturers like Broadlogic, Twinhan, TechniSat, and Hauppauge. Alot of these can be found on eBay for around $50-$150, depending on the manufactuer and the quality of the card. I have one of these in my living room media center PC, but unfortunately the view of the 123 degree orbital slot from my apartment's balcony is blocked by trees, so i'm not able to receive KEXP via satellite, to test the signal out... :-(
