Cheap Rxr with 12 kHz IF
Can anyone suggest a cheapish portable SW receiver with a (roughly) 12
kHz IF stage - which isn't difficult to get at. I think it's time to experiment with DRM. Simon |

Simon 12 kHz IF ????? Yep, that's what I thought. The only free way to decode the DRM data stream is using a software program called DREAM (search for dream.exe) It requires a 12kHz IF to interface to a PC Soundcard. However I may just take the more usual 450 ish and mix it down to 12 kHz. Simon |

NOTE: Most 1st Stage IFs in "Cheap Receivers" fall into a Band Width Range of 5-9 kHz. wmcis ~ RHF .. .. |

I read thru the link you gave a mod for the Sangean ATS-803A
(RadioiShack DX-440) The mod seems very easy Theres a link to the PDF mod file. These radios are avao;ab;e on EBay under $125- regularly Simon wrote in message . ..

TenTec shows, "1st I-F 45 MHz, 2nd I-F 455 kHz, 3rd I-F 12 kHz" for their RX320 in the spec sheet. RM~ |
