Many questions. Not sure of some answers, so I also addressed others hoping they can contribute where I miss.
First, you may log in as othernet, PW is j7m*2
Second, the small dish is about 35 cm diameter. Bare LNB has not been measured on this device since I changed to the Bullseye, but would likely run in the -9 to -12 area.
Third, as you see the information presented, that is how it is received/processed by the DreamCatcher, with the exception of some files in the “downloads” which were uploaded from a computer to the DC.
Fourth, Radio has not been in use since a recent change, as Syed is working on the programming. However, it does work when there is audio available from the satellite.
Fifth, data such as news programs and APRS seem to store for about two weeks before being overwritten with new data. Weather information is a little behind, and I am not well-versed on all of that program. To find information on any particular place on earth, you can manipulate and click on the large globe, then select the specific data that is available.
The data can be transferred to the storage SD card, then the storage SD can be removed from the DC to carry the data to another device (manually).
As to disruption of a download, there is a certain repetition (I don’t know the time frames) before the data is replaced in the download sequence.
I have run two devices (on separate LNBs) while experimenting, neither affects the other. There is no choice for specific content (one-way, receive only). My unit is up 24/7, and I have had no problems other than when the feed to the satellite has difficulties.
I hope this helps, I am not up on some of the information you need, so if those items are important, please address them again, and we will forward them to others who may be able to assist.
