DTV FREQUENTLY ASKED QUESTIONS

We have received a number of questions and reports from people giving all types of feedback ranging from how great Digital TV is and how clear they can view WLMB to people wondering if we’re even broadcasting digitally. Hopefully these FAQs will help answer some questions that you may have.

Is WLMB currently broadcasting its Digital signal at full power?

Yes, WLMB has been broadcasting its digital signal since January 2005 and is broadcasting at 100% of its licensed power.

Is there a problem with WLMB’s transmitter or will it be upgraded to broadcast stronger?

No. WLMB’s transmitter is meeting and surpassing all FCC requirements as well as maximizing our FCC licensed power output.

Why can’t I get WLMB on my new TV or using my converter box?

It is hard to say exactly why you may be having problems receiving WLMB’s digital signal. Here are a couple factors that may help you receive WLMB.

Antenna – The licensed frequency for WLMB (Channel 5) is a low band VHF frequency. This means that you will need a VHF antenna in order to receive WLMB.  For more information on what antenna to use, visit http://www.antennaweb.org.

Transmitter Location – Although WLMB’s offices are located in Toledo, OH, the broadcast signal actually comes from Jasper, MI (a small town located about 11 miles south of Adrian, MI), and it will likely be necessary to point your antenna in that direction to receive WLMB.

Channel Scans – Sometimes it is necessary to do multiple channel scans on your converter box with your antenna in different positions to receive all the different television stations including WLMB.

WLMB’s DTV channel assignment – Although when you receive WLMB’s digital signal it shows as 40-1, it is actually being broadcast on channel 5. The nature of DTV allows stations to broadcast on a specific channel yet appear with a different number on your TV or converter box. This is called “channel mapping.”  Many Digital TV’s and converter boxes come with a signal strength meter so you can see how strong the signal is on a specific channel. Many people use this feature to see how they need to move their antenna in order to get the strongest signal. It is important to realize that until you have received WLMB digitally for the first time, you will need to tune your converter box to channel 5-1 and then monitor the signal strength. Once you receive WLMB, it will automatically “channel map” and show up on your TV as channel 40-1.


Do I need to get a converter box in order to receive WLMB’s digital signal?

If you watch WLMB using an antenna (“rabbit ears” or roof-top antenna) and your TV does not have a digital tuner, you will need to purchase a converter box in order to receive WLMB’s digital signal.

How do I tell if my TV has a digital tuner?

Here are a couple key words to look for either on your TV or in your manual to tell if your TV has a digital tuner.

ATSC – if your TV has this logo on it, or if your manual says that your TV includes an ATSC tuner, your TV has a digital tuner.

DTV – if your TV has this logo on it, your TV should have a digital tuner.

Check where the antenna plugs in (usually in the back of the TV) to see if there is anything that refers to digital television, ATSC, or DTV. If any of these items are there, your TV should have a digital tuner.

If you have a TV older than a couple years, and you don’t see any of these signs, it is very likely that your TV does not have a digital tuner and you will either need a converter box or a new TV to receive Digital Television. If you still are not sure if your TV has a digital tuner, contact the TV manufacturer to see if it has a digital tuner.
