I don't wish to be picky, but on the topic of KSEA approach taking over the ZSE Paine Sector, I have certainly noticed some differences in the level of service. For one, they are often slow to give you a transponder code when entering their airspace and initially requesting VFR flight following. One time, I departed Harvey at night and did not get my code until I was all the way North of Arlington. Sort of defeats the purpose of flight following. Secondly, the actual transmission sounds, in my honest opinion, to be much weaker. I assumed that the same radio frequency repeaters would be used, but maybe the radio equipment from the RAPCON building is different then from the ZSE Auburn facility. The signal from KSEA App just south of Paine has always been spotty at low level. Now the sound quality is not as good all throughout the sector. Again, not complaining here, just sating some observations on the occasion of the roll over to ZSE. Anyone else notice more differences?
