Do not connect to an antenna in the nearfield of a transmitting antenna?

Post by elbow » Thu Feb 22, 2018 8:15 am

Hi,

I'm busy with an amateur radio course. On Saturday our class has a "field trip" where we will make some HF contacts using a 100W HF transceiver working into a temporary antenna. I'm going to guess we'll use 40M.

I thought to take my RSP1 along and set it up with a longwire of some sort and perhaps show my fellow students what it can do.

But I see the warning about overloading the RSP1 with pickup from the local transmitter.

Do I need to worry about that? Should I rather leave my RSP1 at home?

Thanks,
Elbow

Maximum input is either 0 or 10dBm (I can't recall at the moment). If your field strength will be that high at the antenna port, add an attenuator. Never leave your RSP at home 8-) .
