Comment on Our Review of the Airspy HF+: Compared against ColibriNANO, Airspy Mini, RSP2 by Kevin Alewine

Have used the Afedri-Net SDR for a few years. Nice radio but it’s lack of front end filtering and images below 500 khz has been problematic. Since my primary interest is 0-30 MHz, the AirSpy HF+ is a no brainier for an upgrade.

Just curious, but does this SDR have the ability to upgrade the firmware to fix bugs or (better yet) add features?

Can someone link a video for dummies lol. I have Unitrunker, DSD+, and SDR# installed. I can’t…

Can someone link a video for dummies lol. I have Unitrunker, DSD+, and SDR# installed. I can't download from RRDB because I'm not a premium member. So how do I get these programs to work together to listen to WV-CABELL county, Huntington police department? Oh running windows 8 and a RTL-SDR V3 dongle

Comment on Buy RTL-SDR Dongles (RTL2832U) by ROBERT CARLSON MD

Dear Sirs:

I purchased one of your RTL-SDR V3 units. It works fine on VHF / UHF but I can’t get HF to work right. I have the latest SDR# software from AirSpy installed on Win 10 running in Direct Sampling Q mode. With a good HF antenna I can see plenty of strong signals on the SDR# display, some over SNR 30db but the AM, USB, LSB, DSB audio is barely discernible and buried in the noise, even on a strong signal like WWV. I’m not sure if it’s the hardware or a setting, though I have experimented for hours with various settings to no avail. Any suggestions?

Comment on A Tutorial on Receiving HRPT Weather Satellite Images with an SDRplay RSP2 by RFGeek

I have a DS2090AT telescope mount and I am looking at adapting it to a helical antenna. One challenge I am finding has to do with how to get the antenna to have more than 45 degrees of travel along the vertical path, since the conventional helical antenna ground plane hits the mount and you would have to extend the ground plane away from the mount for that not to happen. If you do move the ground plane out from the mount, the whole antenna is moved out and then the mount becomes unbalanced and does not operate correctly. Whomever wrote the article had a great idea in leaving the DS2090AT mount alone and not modifying it so either a telescope tube or an antenna can be clipped in. Given the ground plane issue, does anyone have any suggestions on how to get a helical antenna to fit on the DS2090AT telescope mount and achieve the full range of vertical travel?

Access to my daytime Meteor .s files (New Jersey)

My auto capture Meteor M2 computer automatically uploads the captured .s file to a public dropbox. You can download them and use either LRPT Anilizer (WIN) or Medet (ALL OS) to decode the file.

Antenna improvements coming shortly.

Troubleshooting Help • Desolder of L13

I am a newbie.

I have the RTL-SDR v2 dongle with LNA4ALL (bias-tee mod). When I soldered the two pads on the RTL-SDR dongle to enable bias-tee I accidentally desoldered the component next to the pad (L13) and I also lost the component :oops:

I am only listening to air band. What should I do?

Is the correct component a 6.3uH inductor smd?
