The Truth about Digital Modulation

There are hidden fence systems that advertise themselves as offering DM, or "Digital Modulation." They claim it's the most up-to-date and cutting-edge radio transmission technology available for secret fence systems. The “next-generation” is, in fact, newer and overall better than FM frequencies.


Digital Modulation (DM) is a signal processing technique for sending and receiving information over FM (Frequency Modulation) or AM (Amplitude Modulation) radio waves. It's frequently used today in almost every gadget that performs any sort of communication. Everything from cell phones to hidden fences works by radiating "digitally modulated" signals.

Digital Modulation is the “Digital” form of AM/FM radio.

Everyone is familiar with the distinctions between AM and FM radio. It's well known that FM radio transmissions are far more distinct and safe than AM waves. This is why FM music sounds clear on the radio, with no static, and fire/police departments typically use FM frequencies. In conclusion, digital FM broadcasts are preferable to analog AM signals.


Because of the distinctions between these two types of radio technology, most AM-based hidden fence collars are likely to be affected by interference from numerous other AM radio signals generated by various popular household electronics. The consequence of this interference is a digital AM hidden fence collar that can "misfire," randomly shocking your pet. This may cause an anxious and confused animal.


FM Digital Radio Technology

The reason certain hidden fence companies make a big deal about offering Digital Modulation is that their solutions are based on AM radio technology.


Because digital AM radio is not as clear or safe as digital FM, these companies use clever wording to compete with the ONLY hidden fence brand in the industry that sells an FM digital radio-based product; DogWatch®. By pointing out a frequently utilized technology (DM) and implying that their product is superior because it uses it, these businesses are attempting to divert people's attention away from the fact that their merchandise is AM radio-based.


A consumer who is familiar with the term "DM" understands that it is not a new, "advanced" radio technology offered by a specific hidden fence firm.

A DogWatch® Digital FM Hidden Fence Will NOT Misfire, Making It the SAFEST System for Your Pet

All existing hidden fence devices employ Digital Modulation (DM) as the radio signal processing technology. DM is the technology used to process radio transmissions, regardless of whether the product is based on AM or FM radio. Within the hidden fence sector, there is nothing special, new, or unique about DM's usage. All present-day hidden fences rely on this technology.
