Run Seven

I am havin a problem with radiator's upgrades... my radiators, even in Sandbox mode, do not advance beyond mk2 but there should be up to mk5. Also, my maximum heat dissipation changes with the type of reactor attached to the ship. If I attach a Quantum Singularity Reactor, I get 50GW dissipation, a molten salt reactor only gets 4.3? Sorry if I made some stupid mistake but I could't find anything about this...

I installed the newest version of Joint Reinforcement and now my vessels explode upon rendezvous... They stopped once I uninstalled KJR... what can I do about this?

No, the link from the Jool satellites goes directly to Kerbin.

I am at a loss in this situation, please help. I have 3 satellites in orbit around Jool which have a working connection to Mission Control. Each of the satellites has a KR-7 dish pointed at Tylo. I have 3 more satellites in orbit around Tylo. Each of them has 3 KR-7 dishes pointed at the 3 satellites orbiting Jool respectively. The connection to the satellites around Jool seems to be working. But I cannot reach Mission Control. What am I doing wrong?
