We'll have to wait to see how this whole thing plays out. A 1320 diplex would be a last gasp for Arpin and Co. You'd probably NEED to run 50 kW-D, and at least 10 kW-N to cover Providence decently. Lord knows what a directional pattern(or patterns)would look like to protect CKGM in Montreal, CBW Winnipeg, WNTP here in Philly, and CBY in Newfoundland. I'd think that the towers would have to be top-loaded to 1/4 wavelength on 990 for this to even work well..
