In the case of the Delinquent's drop ship, there was some sort of malfunction on the 100 year old piece of space junk that shorted out the communications and didn't deploy all of the parachutes, hence the bumpy ride and rough landing.

Once they got the radio working, the delinquents were able to communicate with the Ark up to Unity Day. I'm guessing that prior to the delinquents landing on earth, Mount Weather had no reason to jam communications (the Grounders don't seem to use that technology). And it was the bridge explosion that caused Lincoln to tell Octavia that the Mountain Men were going to come now because of it.
