Using a 1-meter dish with the Dreamcatcher


#1

I will start by saying that I bought the Dreamcatcher board only a week or two ago and am very happy with it. I first powered it on and discovered that the display wasn’t functional, but I could still configure it through the web interface. After being used in the sun for a few hours, the display mysteriously started working. After a few hours of sitting outside positioning the LNB and trying to keep it pointed at the satellite, I decided to have a go at using the 1-meter dish that I was sitting next to. It is an old Direcway dish that I originally intended to use for receiving the GOES-16 weather satellite. Even though the dish isn’t pointed very accurately (i unknowingly installed it on a small sinkhole), I get a (relatively) good SNR usually staying at around 8-9 dB from setting the elevation and using an iPhone compass to set the azimuth. A while back I remember reading a post where the beam type was changed which increased the data rates, and there was one type mentioned that would allow for roughly 1 Mbps if I remember correctly. I was wondering if it would be possible to achieve this or maybe even higher data rates with my current setup (and maybe pointing the dish properly). During this test, I remember that the receivability dropped off with higher data rates, and the roughly 1 Mbps was never attempted. Is anyone else using a dish with their setup? What kinds of data rates would be possible if using a dish versus just using the LNB?

Your bitrate and packet rate is at the maximum. Since you are getting 100% decoding of the packets - you are achieving the best currently available.

I was referring to a post a while ago about a “planned service disruption” where I assume the beam type from the satellite was changed which allowed for higher data rates, although it stopped being receivable after some changes. I’ll try to find the original post.

I do wonder if this were done again sometime if it would be possible to get the higher data rates with a dish.
