Other SDR Devices • Re: Dreamcatcher user here?

perfect. :D Sure I need to hang an Filter in front of the device.
Which OS do you run on the Device? How to connect to?

Why do some FM radio stations have a wider bandwidth than 250 kHz, while the majority are less than 250 kHz?

While looking through some of the FM band, I noticed that the majority of radio stations fit well within the 250 kHz bandwidth limit of the WFM option in SDR#, but some will extend a good amount beyond 250 kHz.

Station within 250 kHz (like the majority of them): https://i.imgur.com/7JrrKO4.jpg

Station extending beyond 250 kHz: https://i.imgur.com/5OR4zRR.jpg

RTL-SDR Discussion • Re: SDR without Sound card? Multiple channels in parallel?

You can use the multi-VFO plugin for SDR# to get simultaneous audio from multiple frequencies http://www.rtl-sdr.ru/page/novyj-plagin-3.

SDR-Console also already has multi-VFO capabilities built in.

For each VFO you'll need to route the audio to a separate virtual audio cable (you can use VAC or VBCable).

Not getting anymore weather images from NOAA

Last week, my qfh antenna was still lying on the ground and I was able to get clear images in the center. Today, I leaned the support of the antenna against my pergola. I tried receiving weather from 15, 18 and 19 with elevations above 80, I just get noise. I double checked all the connections and even removed the lna. Still no luck. I can tune to fm stations and noaa radio fine. Are the APT satellites affected by cold weather? It's exactly what I encountered last year around this month as well. Our temps suddenly dropped to 30s this week.
