Thanks for the heads up. I was listening to 133.975 this morning and all southbound traffic along J48 and J75 at FL340 and above was still being handed off to 134.625. However I tuned in 127.925 to see if it was in use and could hear traffic operating in the same area as the 134.625 sector. From what I heard, all traffic southbound on J48/J75 on the handoff from 133.975 was only using 134.625, but all the other traffic in the same sector (as 134.625) was using 127.925. So they appeared to be using both frequencies for the same sector, maybe they split them when it gets busy ? DJ
