That would be my great worry about using a Welbrook-type amplified loop in the local presence of a TX.

There's enough 'stray RF' flying around here when I run 100W on 80M to cause my broadband-router to lock up [overhead-wire phone lines are not helpful] and in times-past I remember repeated failures of a short 'active antenna' when used close to a transmitter.

There's also the issue that your receive-loop may be directional whereas the longwire/dipole you're using for transmission is differently-directional, so replies to your "is this frequency in use?" calls may not be heard and you start calling CQ over the top of existing contacts.
