In terms of the survey question, I find the Kenwood TM-D700 easily fooled by nearby sources of interference. Other radios don't pick up the interference. Some of them have helical filters built-in, and reject out-of-band interference.
I run my d-700 most of the time in V/V mode, aprs on one side and the local repeater on the other. If I am near high rf areas like paging transmitters they will interfere with the downlink.
I work near a hospital so i installed a ANLI active helical filter in the feedline . model nf-2v.
This work very well. if want to use the uhf side of the d700 i just take it out.
