Traditionally, radio stations have always broadcasted in its regular, analog format. FM and AM radio could both be heard all over the world depending on the signal strength in each listening area. A couple of decades ago though, analog radio has been replaced by a better type of radio; digital radio. Satellite music has grown in popularity tremendously since it first debuted, and shows no signs of any decrease in popularity because it is all around better than traditional, analog radio. During the process of radio stations switching over from analog Satellite music, most stations broadcasted in a hybrid signal that could be heard by regular radio listeners as well as digital radio listeners. Over time however, the hybrid signals were no longer used because the complete switch over to digital finally happened. Analog radio offered a selection of different AM and FM radio stations in each listening area but once the switch over to digital was complete, listeners could enjoy even more stations in their area thanks in part to the stronger digital signal. With digital radio, FM stations were broadcasted with such a clear and crisp signal that the music sounded the same quality as that on a CD. AM stations also improved significantly by gaining the same sound quality as traditional FM radio. To listen to all of the advantages that radio had to offer, listeners would have to purchase a digital receiver to pick up the digital signals. Digital receivers could not only pick up all the newer digital stations, but they could also pick up all of the regular radio stations that were around before digital Satellite music. The downside to purchasing a digital receiver lies in the cost; the cost of a digital receiver was considered rather pricey when compared to a regular, non digital Satellite music. Traditional analog radio did have its advantages, such as when the signal strength became diminished, the stations would lose their sound quality slowly. However, with digital radio, should the signal become reduced, the stations will usually cut out completely; this is one of the major disadvantages to along with the cost of a digital receiver. All in all though, digital radio is coming along and progressing further and further as the year progress. While FM Satellite music has always been considered pretty good when it comes to quality of sound, digital radio is going to take FM radio above and beyond where it was previously with no signs of it slowing down.

The Sangean PR-D7 has a clean crisp sound with very low noise floor on AM and FM bands, a great improvement over Sangean radios of similar size such as the ATS-505 or the ATS-909. BTW, I’ve tuned in all the major stations in the greater Phoenix area without a problem including the hard to catch 89.5, a classical station. I have been very surprised at the overall performance of the PR-D7 radio and listen to this radio on a daily basis. The Sangean PR-D7 ($59) does 90 percent of what the Trivoli Songbook does at 25 percent of the Songbook’s $200 price tag. Still, the PR-D7 could use a multi-voltage AC adapter and a lock switch to be a complete global travel radio (like the Sangean ATS-606). Also, when traveling, cloth pouch would be a really nice touch. And while I’m making my wish list, the PR-D7 in a red or yellow case would be neat and easy to spot in a hotel room so you don’t leave it behind. One of the things I like about this radio are the controls, easy to learn and use, plus you can see the frequency and time on the display. Update September 2008: I just recently purchased Sanyo’s Eneloop AA rechargeable batteries for my PR-D7 giving me greater flexibility when enjoying this wonderful portable radio. I highly recommend Sanyo’s Eneloop batteries. Last week, from my greater Phoenix location, I picked KNX 1070 Los Angeles about 10PM in the evening. Update October 2009: After owning this radio for 2 years, my little PR-D7 fell off a second story balcony and is now in pieces, so I ordered a second PR-D7 this morning. I suffer from cancer and kidney disease, so I’ve been in and out of the hospital several times this year, each time, my little Sangean PR-D7 went with me. One of the neatest features of this PR-D7 is the no hassle recharging of the AA batteries, the radio automatically does this for you!!! BTW, I ordered this radio from Amazon on a Friday morning and received the radio the next Tuesday morning. How’s that for service!!! Update January 2011: I have since purchased a Sangean PR-D9W radio which is now my go 2 radio. 85 of 85 people found the following review helpful. 88 of 92 people found the following review helpful. Pros: Cons: I applaud Sangean for making a nice little unit that gives the Songbook a run for its money, but I still think there is room for improvement in this radio. |
