Southwest Using MOTOTRBO at BWI?

[dtscho]

Anyone confirm whether Southwest is using MOTOTRBO at BWI? The airline has two licenses, and they both indicate MOTOTRBO, according to the emission designators.

I'll check and advise.

EDIT: Interestingly, freqs 6,2,3,7,8,4 of WPVU767 are the same freqs as WQPX688's base freqs.

I'm getting DMR on 453.0125 (WPVU767 Loc 1 Ant 2 Freq 3). Appears to be a standard standalone repeater right now, nothing indicative of Cap Plus. I saw another freq flash by with a PL tone (therefore straight FM), but I didn't see which one it was (I think it was a WQPX688 freq). So it appears they're switching but not complete. Given the numbers of freqs, I'm hazarding a guess that it will eventually turn into a Cap Plus system.

Thanks. 453.0125 is also licensed to Johns Hopkins University, and the license indicates they may be using TRBO on it too.

I was up at the Thomas A. Dixon Jr. Aircraft Observation Area on Tuesday, and can confirm that Southwest continues to use analog frequencies. United has switched to TRBO on 460.8250.
