Noticing a couple of the sites in the Portland area, sites 2 and 45 have a control channel that pulses and is not continuous, makes for a troublesome decode. Whereas other sites such as 1 and 5 transmit continuous. Verified with multiple scanners and an SDR. Anyone else seeing this?

Yup. Same here on the pulse for Mt. Scott (45) and Chehalem (2) sites. Haven't seen others like that so far. Ones that I have seen are running a CapMAX control channel and usually 1 other voice channel or more depending on the site location and if it is in a metro area or not seems to the be the rule of thumb on their buildout so far.

Still have an elusive site in the Portland area which is "Site 71". Only seen by Council Crest (1) and Mt. Scott (45).

And I'm hoping that some others will help in filling out other Oregon, Washington, and Idaho sites with more than just 454 MHz channels. Those part 22 assignments don't have a location normally since they are a auctioned spectrum. Those that I have found usually have 1 other channel in part 90 that helps to narrow it down. Not always, but most of the time.

Good, not just me. Still not a ton of activity on the system so not sure if maybe if no one is affiliated to the sites it goes into a power save mode or what's going on? I'm guessing they are not in a big hurry to move customers from one system to another as I know the older 4550 and 6550 radios will definitely not do Tier 3 Capacity Max and maybe even the older non E model 7550 and 5550 radios? Which alot of the older customers still have.
Not sure on the site 71 either, my thought was it is a test system running low power at HQ? I haven't seen any 454 freqs for DMR in the metro area, think the closest I have seen are Capitol Peak and Puget Sound region.

Also on Friday I verified that an SDS100 will not track sites with a pulsed control channel, and the control channel does not change from pulsed when there is voice traffic on another frequency at the site, so it's not a power save thing. Very weird!

I am noticing with DSD+ that some sites seem to have an issue with a "slot" hanging after transmission. I haven't been able to tell if it is a "bug" with DSD+ or their system. I'm sure if you are seeing the tracking issue on the SDS, I'm pretty sure HP series will do the same thing. I haven't tried it though.

I also attempted to scope out Site 71 in Milwaukie as we thought it could be. Nope. Sat right there in a parking lot with eyes on the building and that isn't the spot. Site 71 still remains elusive.

No issues with the WA sites so far.

BTW, Gold Mtn:

Site H0-9
DCC:15
CC FREQ: 454.03125 LSN:807
V1 FREQ: 454.39375 LSN:398

Site H0-69 is getting voice traffic now. Trying to locate the voice channel.

Gold should be 10 and Capitol should be 9 if they are following the same pattern as the Connect Plus system?
