[RFI] RFI heard on Alinco DR-135T MKii on 2m

[David Colburn]

I can hear APRS on 144.390.

But I'm also hearing a lot of cyclical noise bursts (see attached audio 
clip).

Anyone recognize it, please?

I've excluded a window A/C unit and a split A/C unit.

WDYT I should be looking for, please?

Thanks,
