Agree.

Nothing much you can do about it if that's the case, correct?
INcorrect. IF that were your problem, the interfering signal is nearly 180 degrees off-axis, so there are definitely things you could do, but I agree that's UNlikely to be your issue, so let's not go there.

My (very uneducated) guess is that WBFF isn't operating at full power given the issues the area has faced with the repack
I doubt it. My rf25 and rf26 look just as they should on my TiVos, given that 26 is approximately 2.5 dB weaker.

This is my rabbitears report, which you can see is very similar to yours:

https://www.rabbitears.info/searchma...study_id=92405

How is your reception on WNUV, what antenna are you using, and where/how is it installed?

Is the WBFF reception worse during windy weather as we've had this week? If so, then probably multipath interference from trees blowing around.


I'm only 12 miles from the transmitter (compared to OP's 50) but WBFF has oddly seemed more prone to multipath at my house than WNUV even before the repack change. As I type on this windy morning I see WBFF's signal fluctuating between 80 and 100% while WNUV is a steady 100%.



Re the low power theory, in the Live Bandscan section of rabbitears.info WBFF looks marginally stronger from the Leesburg monitor and slightly worse from Alexandria since the mid-March repack. I see no weakness 12 miles out.

Have they started work on these towers?

According to WJZ's progress report that they filed last week, they didn't begin tower work yet.

WBAL's progress report from May 4th says they'll transition to an auxiliary antenna at reduced power and won't complete their final facility until after July when their contractor can schedule a helicopter crew:

Thanks for the feedback. My reception on WNUV is non-existent, similar to WBFF (from what I remember, I was picking WNUV up a few months ago, but nothing recently). I have a ClearStream 2Max, which is set up outside next to our deck door. It's about 13 feet off the ground and faces Northeast. I promised the Mrs. I won't put the antenna on the roof, so that's not an option.

Yep, no 45 or 54 here either. They are both a tad weaker than channel 2 which is a bit too weak to decode as well. 54 used to be good here when on RF 40. OTOH MPT 22 is decode-able since the re-pack, even with the antenna pointed towards Baltimore.

I have a Terk MTVGLS that is picking up Baltimore stations and WMPT in Annapolis, but not DC ones. I might be able to setup a small outdoor antenna in my balcony. What antenna do you recommend I try?

My Rabbit Ears study ID is 93103.

Thanks!

Do you get *any* DC stations? Is there anything especially challenging about your location - e.g., basement apartment? That is an amplified antenna. Can you try without the amplifier? You could be overloading your tv tuner, being so close to DC. A simple rabbit ears and loop, like this, should get you the DC stations, in theory.

I am in a 15th floor unit and the compass app on my phone claims it is has an elevation of 140 feet. The unit faces away from the DC broadcast towers. I was mistaken, the Terk MTVGLS is able to pick up channels 50 and 66 with the amplifier plugged in. Today I am getting 14 as well. I have scanned for channels with it being unplugged and it was not able to pick up 4, 5, 7, 9 , 20, or 32. I might get some RG6 coax to be able to try the antenna on my balcony.

I'm having the exact same experience as you. It used to be that I could pick up WBFF-45 without any problem, and MPT-22 was hit or miss. Now, I can't pick up 45 at all, and I pick up MPT-22 more often than WHUT-32.

Too bad the re-pack has reduced power to areas that used to get a decent signal. Not sure why the FCC is so overly protective of TV signals and then seem to not protect the FM band with HD & LPFM stations?

Look at the coverage map for WWEG below. WJFK's HD signal wipes out a good chunk of the southeastern half of WWEG's listening area. I would think WWEG would not be too happy about this? How does this happen?

Not quite clear what this means. Each station was replicated to a power that matched its pre-repack contour on the new channel. For WBFF, that 655 kW on channel 46 becamne 440 kW on channel 26. For some reason, they opted to build at only 420 kW, which is about 0.2 dB less--I can't imagine anyone would notice. For WNUV, the 845 kW on channel 40 became 620 kW on channel 25, but WNUV voluntarily increased power to 750 kW when they built it.

Thanks Trip, I wasn't aware they were trying to replicate the previous coverage areas. For whatever reason I'm not getting any Baltimore channels now. There can be a lot of other factors that come into play as well. I am already on the edge of Baltimore's coverage anyway and the leaves on the trees aren't helping either.

A neighbor in a different building bought a Clearstream 2Max antenna and picks up 55 channels. I bought one since the dipoles and 2 round UHF portions could be an improvement over the flat amplified Terk antenna. Surprisingly the 2Max performed better as it was placed further away from the balcony. I have the antenna in the HVAC closet, where the in-wall coax cables originates, facing around 330 degrees and it is receiving 50 channels. The only major network I missing NBC. WRC NBC 4 broadcasts in the UHF band so I am surprised it doesn't come in and WBAL 11 broadcasts on VHF that doesn't reach Alexandria/Fairfax County. I'll have to share my findings with my Montebello Condo neighbors.

Ah! I could just about throw a rock and hit you. This is a live list of what I receive off my roof antenna, which needs work:

Howdy neighbor! I moved the antenna to the walk-in closet by the front door, which is slightly further north east portion of my unit. Now I can pick up NBC 4 and a few other stations. I may trim the coax cable I ran from the antenna to the in-wall coax origination since the big box retailer substituted a 100 ft roll for a 50 ft one. It looks a mess and the excess cable may allow signal degradation. My TV's signal meter shows some of the channels in the 40% range, lower than it the antenna connected directly to it.

Ion's outdated rescan website still says 5/1 for WWPX, but since they have to coordinate with all those other swaps stretching from DC to NYC, they'll be doing it at the same time.

Thanks for the update. I hope these changes improve their signals.

WBAL and WJZ reception may get worse before they get better as it sounds like they will need to run off backup hardware initially, as per baltomedia.net on May 28, due to lack of helicopter crews and needing to use cranes for the replacement antenna work.

Thanks for this useful information but actually WBZ was part of Phase 4 and not Phase 10. It's also located in Boston, MA. Just having a little fun with you!
