Hi Ron and Dave,
First off I want to say thanks for providing the feeds, great reception, very much appreciated ! To be clear I'm happy no matter how you have them set up but thought I'd throw out a few observations just for the sake of discussion. I'm not complaining, this is just my "Obsessive Complusive ARTCC Monitoring Disorder" (OCAMD) showing.
on JFK#4, flights on ZNY 134.6 can get handed off to ZDC 121.02 or to ZNY 134.32 depending on the direction they are going.
As far as New York Metro departures and typical traffic flows go I think you will find 134.60 almost always hands off to 134.32 and not to 121.02. As for 121.02, used for southbound routings, the main flow is 118.97 to 121.02 to 132.55/120.97/121.37. Also when traffic is light 121.02 is combined with 133.12. For these reasons I would remove 121.025 from #4 and put it on #2.
Lately as noted on the other thread, ZDC has been combining 132.55 with 120.97 so I would add 132.55 to the #2 as well for coverage.
On Radio #4 I would add 132.10. This frequency is combined with 134.60 when traffic is light and handles the New York Metro flow in basically the same area/direction (southwest) as 134.60. (basically 134.60 over fixes LANNA, BIGGY, and 132.10 over fixes NEWEL, ZIMMZ, PARKE).
Radio #3 is good but I would add 125.92 for coverage as this sector seems to be usually combined with 133.50. This would compliment the ZNY New York Center (JOBOC Sector) radio that has good controller reception on 133.50/125.92 but poor aircraft reception.
I have mixed thoughts on Radio #1. It's kinda overloaded with the ZDC frequencies that are primarily northbound with EWR and LGA arrivals combined with the ZNY frequencies that are primarily southbound. I'm thinking it might be better to remove the ZDC freqs and just keep the ZNY ones on #1 and put 132.17 on #1 for similar area coverage.
The ZDC northbound freqs need there own feed. What MIAMIATC suggested with his Radio 2 idea makes sense. Without 133.97, that should be on your Radio #4 grouping.
This is what I would do.
Radio #1
125.575
127.175
125.325
132.175
128.500 - spare
Radio #2
134.600
132.100
134.325
133.975
134.375 - spare
128.675 - spare
124.775 - spare
Radio #3
126.875
132.275
125.450
132.525
Radio #4
128.300
127.700
132.050 (combines with 127.70)
133.500
125.925
121.125 - spare
Radio #5 (use the ZNY ATL86/ZDC SIE54 radio)
118.975
121.025
133.125
132.550
120.975
121.375
134.025 - spare
I know there is no Radio #5, but this area is already covered very well by the "ZNY ATL86/ZDC SIE54" radio. On that radio I would remove 133.50 which is already covered on two other radios, as well as remove 125.32, covered by the JFK radios, and replace it with the closer ZDC sectors (132.55/120.97/121.37).
IMHO this would be the best way to optimize coverage in the area, without having too many frequencies on any one radio, avoid overlap between radios, and take into consideration geographic area and primary traffic flow.
Anyway just a suggestion. Again I'm very happy having the feeds available, however they are set up. Thanks to all who provide these Center Radios ! Although it's not helping my OCAMD problem.
