I received my MFJ-1621 last week, but had not had time to hook it up. As soon as I get some time, I hope to hook it up and test it out. It has been promised by reviews that is can operate "on the bed in a hoteltu room", so... Ill try to replicate the situation and post my findings. To be fair, I will also test it in a Picnic Portable sitaution to see how well it works there.
