英国爱好者向我请求帮助,关于DRM接收 近日,收到英国伦敦爱好者的电邮,是因为我在国外论坛留过邮箱地址。邮件如下: Dear Friend, I bought 100KHz-1.7GHz Full Band U/V HF RTL-SDR USB Tuner Receiver/ R820T P7K5. I am able to receive all FM radio channels in London using the SDSharp software. I like to receive DRM transmission from BBC,UK (3995 KHz) and 17790 KHz. I have installed Dream software and I do not know how to receive DRM transmission. What type of antenna is needed to receive DRM signals. Kindly send me all the details to receive DRM stations using my RTL-SDR USB tuner receiver. Thank you 然后我回复了如下,英文不好,软件翻译的,勿喷 Dear 此处名字不透露 Thanks for your email very much! I come from china, I very happy when I received an your email from London, I think I can help you! Your RTL-SDR can receive HF, so it is no problem! The type of antenna can is a long electric wire, it’s length can select 1/4 of wave length, the antennas need to be installed in outdoors, the distance from the ground is greater than 2m best. Are you in London, the 3955kHz signal should be strong(Is not 3995kHz), but 17790kHz signal may be weak in London, because 17790kHz transmit from Singapore(Asia), it’s very far. Use SDR and dream software to receive DRM transmission need installed Virtual Audio Cable, only you can keep in touch with me, I can provide all software and help you. SDSharp software need select “USB” mode , than cover DRM signal completely, bandwidth can greater than 11KHz,than set SDSharp output audio select to Virtual Audio Cable, than set Dream software input audio select to Virtual Audio Cable, then adjust the volume to the appropriate level, This can. The dream software need add” faad_drm.dll” file to root directory , it is a AAC+ audio decoder, If there is no it, Will not output sound. If you don't have ” faad_drm.dll” file, I can sent it to you 然后他回复了,如下 Dear 元芳, Thank you very much for your reply. I appreciate your willingness to help me. I use SDRSharp to receive FM radio in London. I live in 5th Floor apartment and the balcony has a long aluminium hand railing about 100 ft long, and I think that will work as short wave antenna for receiving DRM stations. I have a long wire of about 60 ft also for use as shortwave antenna. Which one is better? Do I need to install both SDRSharp and Dream software to receive DRM stations? My dream soft ware did not have faad_drm.dll file. Kindly send me that file. Which version of Dream software are you using? I request you to send me the link for downloading SDRSharp and Dream software which you are using. So I can follow your steps to receive DRM Stations. Radio France International at 6175 KHz is also transmit DRM programmes with 100 KW power everyday from morning 9.00 to 12.00 noon (UTC time). I think it is convenient for me to test from London. Kindly provide me all the software and also procedure to set up for DRM reception using my RTL-SDR. Thank you,
