It takes the 545 that was designed for HF reception (and also longwave and mediumwave) and makes it a wideband receiver that some like to refer to as a "DC to daylight" receiver due to the frequency coverage. Thus, instead of the receiving frequency ending at 30 MHz, with this module, it will extend up to 1999,995.00.
Thus, its receiving range is 30-823.9, 849.1-868.9, 894.1-1849.9, 1910.1-1929.9 and 1990.1-1999.9 MHz. If you live in Europe and have one of the European NRD-545 receivers, there are no blocked frequencies and you will enjoy tuning without interruption. In case you need a primer on what analog signals you may expect to hear within a receiving range and using a proper antenna, here is a list.
Other emergency personnel & rescue. National Oceanic and Atmospheric Administration Service weather broadcasts. Ham radio 10, 6, 2, 1.2 meters and 70, 33, and 23 cm (in addition to the standard broadcasts on the HF bands).
TV analog audio channels 1 thru 69. GMRS (General Mobile Radio Service). FRS or family handheld units. Military emergency guard and strategic air command.
To get reception outside the HF frequencies, you will need to connect a second antenna that gets reception on the VHF, UHF, and Microwave bands. However, many people get decent results with placing the discone inside in an attic. But the best antenna I have tested is the discone for wideband use and located as high and away from obstacles as can be reasonably done. However, if you want your NRD-545 to be able to tune from 100 KHz to 1999,995.00 MHz (less cellular) and be a "do-all" type receiver, then you will need to have this device to be able to accomplish that. We are happy to answer any questions you may have.
