Harris RF-2601 remote auto ATU
 

I have the chance to buy a RF-2601 new in its boxes. Can anyone advise me if
an RF-2601 and its control unit are a stand alone installation? The data
sheet advises it is designed to operate with Harris transmitter. Do they
come with an instruction manual? Is further info available? Do you need to
pressurise with nitrogen to achieve full specs of 1KW average power.
