Blue Classic and Ham Radio possible interference

There is no way to guess how a Blue Mini will behave in that environment. IMHO.

My system blue receiver sits in the radio room only a few feet from rigs, feedlines, coax, etc.  It is not grounded to the HAM station ground as recommended.  The 3 ferrite bar antenna, horizontal delta shape, sits on the floor in a bedroom down the hall, a few feet above the basement crawlspace, real ground.  Rarely does it go crazy when I transmit, up to 500w.  It does seem to not like 80m when transmitting over 100w sometimes. 

There is little reason to put the antenna or mini on a tower.  The e-field antenna--maybe.  I have not used my e-field components so have no experience.  There may be issues with long cable runs.

You want your antennas in as quiet a place as possible.   Use an AM/LF portable radio and search for as quiet a place as you can find and that is probably where you want to put your antenna.  Use a good, clean, low-noise power supply and some ferrite chokes on the cord if needed.
