Can I use the narrow bandwidth, ssb and bfo on longwave and medium wave bands, or does this only work on shortwave?
You can use the narrow/wide bandwidth switch on LW and MW, but you can only use SSB mode (and the BFO) on SW. The Thieking & Koch version of the DE1121 does allow the use of ssb on LW & MW as well as SW (see below). • What types of antennas can I connect to the external antenna jack? AM, SW and FM reception can all benefit from an external antenna. The external antenna jack on the DE1121 takes an 1/8″ mini plug. Degen sells two amplified loop antennas that work well with the radio, the DE31 for shortwave and the DE33 for both shortwave and AM. I have the DE31 and it noticeably improves shortwave reception. A different type of antenna is needed for FM. Most FM antennas use an F type coax connector. Radio Shack sells a F Jack to 1/8″ Male Plug adapter (Model: 278-267) that works well with the DE1121. I took the dipole antenna off my Sony XDRF1HD tuner (which is the best FM tuner I’ve ever used) and connected it to the external antenna jack on the Degen DE1121 using the adapter. FM recept
