I think part of the problem when discussing 'good receiver performance' is in the definition. In a trail friendly radio I expect a receiver that is able create a readable signal with a very inefficient antenna. To me a TFR doesn't have to worry so much about blocking locally produced strong signals. I wouldn't expect a TFR to do well as well as a K3 at a multi-transmitter contest site such as Field Day.
