Hi all,

wondering anyone have face any RFI issues for two ATC radio (same model) place in the same place with their antenna around 6m apart? There are no additional external filter systems except those came built in with the radio. The radio is operating in V/UHF band.

Thanks.

"ralph" = crossposting jerk off.

** No context = meaningless.

Describe what sort of issues ?

** Also meaningless - you MUST describe the radios.

** Describe the "place" - you PITA fool.

Might be an undergrounds basement for all we know.

** No facts, no details, no clue as to what the Q is really about.

Get real pal, supply the context and details or else

PISS OFF !!

You appear to be writing from singapore. I assume that ATC mean "air training corps" ? I would like to think that "air traffic control" would have professional advise on their radio installations.

I assume that the radio's are transceivers?

It depends a bit on the transmitter power but it is very likely that when one is transmitting the receiver in the other on the same band will be blocked or will have reduced sensitivity.

If one is being used on VHF and the other on UHF then blocking will be less of a problem unless the UHF radio is on or near a frequency that happens to be a multiple of the VHF frequency.

Vertical seperation of the antennas may help a bit.

On receive, hopefully the radios are well designed and the local oscillator frequencys are well out of band and well screened so won't be a problem.
