Dulles MWAA Re-banding

[SkyPager]

My sources tell me that the MWAA system at Dulles is being re-banded Monday - Wednesday of this week. Subtract 15 MHz. Work appears to be ocurring overnight. No other info available.

According to the database, some of the freqs of this system have a '0' in the 4th decimal position, so some reprogramming, along with custom tables, will be needed for many scanners. See this message from our wiki forum...

Running UniTrunker on it right now, this is what I'm getting.

LCN 35 851.8875
LCN 61 852.5375
LCN 466 862.6625
LCN 476 862.9125
LCN 487 863.1875
LCN 657 Alt cc
LCN 658 Alt cc
LCN 688 868.2125 control channel
LCN 829 Alt cc


The radio tech TG is pretty active. But my Pro-106 is only partially receiving comms. It seems like when they're on 862.6625 I get nothing but static.

Today I loaded the rebanded table and was tracking the system fine.

I uploaded a new configuration using what is currently in the database to the RR.com owned PSR-500, providing the MWAA public safety feed, and it appears to stop on channels but I get no audio from the scanner. I'm hopeful that I did something stupid like mute something, and I'll discover it as soon as I publish this post. However, in the event that something else is awry, does someone have a PSR-500/PRO-106 configuration that I can try?

You need to have this table programmed.

 

[j2brown]

That looks like what I have, except I didn't have the 800 MHz "Rebanded" selected for the "Standard" band plans. I've fixed that. It's still stopping on channels, but there's no audio. A quick switch to WX shows me that the scanner can make noise and I can hear it through RR.com. Any other thoughts?

So the setting reverts to <select>, but maybe that's expected.

Tried changing Trunking Tables to Custom from Default. That was the issue. Operator error. Easy to fix, once you fix the operator.

Thanks for the help.

Also noticing that today an alternate control channel is in use.

Hate to be the bearer of bad news but you are nearly a year later.

They have a new filing. For regional interop apparently. Adding emission designators for encryption.
