The output of the transmitter on the proper frequency is reduced significantly as well. Depending on the channels of each transmitter those spurs can be quite large signals on top of other channels.
At what distance do these spurs/transmitter output become significant? (As you bring them closer)

My Hobbico scanner arrived today. Wished I had known about the optional extra antenna. Range is 300 feet without the external antenna and up to 800 feet with the external antenna. It is very compact and fits in a shirt pocket.
