I have noticed we are always short on communication. So all my future scansat satellite will be equipped with relays to communicate with the two planets in the neighborhood. In this case, the Dres scansatter will be equipped with 3 dishes, one to reach Kerbin, of course, one to reach Duna and one to reach Jool.
relay to kerbin 38m+14m = 52m : Reflectron KR-14
relay to duna 38m + 22m = 60m : RA-100 Relay Antenna
relay to jool 38m + 68m = 106m : CommTech-1
This sat will be equipped with all scansats parts, all science parts i have at this time and a survey scanner.
