Can anyone closer to PDX confirm if this system is still active (control channel). I use to be able to receive in Beaverton/Hillsboro, but I pulled it up recently and I hear nothing. Freqs 380.075, 380.275, 381.425cc, 381.950cc, 385.2125
Thanks!

Yes, still active, no change in frequencies.

I have been out at PDX several times in the last few weeks. The system is not super busy with the lack of daily training flights, but I still heard maintenance units talking.

I can sometimes pick it up from my QTH in Aloha if the conditions are just right. But most of the time it comes in well as I head down the hill on Highway 26 into the tunnels.

Somewhere between FOE, PDX, RNO or YVR
If the federal guru Chris says they are still there then they are still there!

I think they may have changed antennas or turned down the power or something. I'm less than 2 miles from PDX and used to get booming signal from the ANG system but recently the signal seems significantly weaker. I can hear TSA better than ANG anymore and I believe they're 5 watts simplex

Certainly possible they made some changes. The system seemed to have a pretty large footprint for just covering the south side of the airport!

Makes sense. VHF vs UHF propagation but still. I use to be mobile and able to tune the control channel in Hillsboro and at home w/beam had a good decode using a cheap SDR. Most recently after being off the Sylvan exit and still no RX with open squelch I started to think it might be their end.
