For me in Sterling, WJZ-DT 13 on UHF 38 at 1000 kW has been much more reliable and east to get compared to WMAR-DT 2 on UHF 52 at 613 kW and WBAL-DT on UHF 59 at 513 kW. WBAL-DT is the weakest and most prone to dropouts of the 3, in part because it is/(soon to be was) located at the upper end of the UHF range with the poorest propagation. Of course, the UHF antenna used plays a big role in this because of different gain responses over the UHF channels.

I suspect that some locations have had a more difficult time getting WJZ-DT on UHF 39 because of adjacent channel interference from WJLA-DT 7 on UHF 39 at 646 kW in DC. That goes away tomorrow when WJLA-DT moves to 7. However, for systems2000 and those located well NW of Baltimore, WJAL-DT 68 near Chambersburg, PA will be increasing to 105 kW on UHF 39 which is not going to help with WMAR-DT 2 reception on 38. The FCC should allow WJAL-DT to either move to DC or have it to relocate to a tower in Hagerstown so it is co-located with the other Hagerstown antennas, if there is a good UHF channel slot left for WJAL-DT to use there.
As for WMPT-DT 22 on 42, I have never gotten the digital station reliably where I am in north Sterling. My antenna is in the attic and WMPT-DT is in a poor direction, basically lengthwise down a row of the top of townhouses. My signal strength on UHF 42 is back to 1-3 bars, so either it was tropo earlier in the week or WMPT-DT was testing increased power in preparation for a permanent increase to 439 kW tomorrow. I get WFPT-DT 62 in Frederick just fine and even now get WMPB-DT 67 in Baltimore much of the time, so getting WMPT-DT is not vital. With WWPB-DT MPT 31 in Hagerstown going to 1000 kW, I might well get that even with the CM 4221 aimed at Baltimore, which could put me in the rather redundant position of getting four MPT stations OTA.
