Hi, I need help on receiving RTTY DDK9 Hamburg Meteo on 10100.800 khz and similar meteo stations. I followed the tutorial on the Paolo Romani's Big Book (page 168), finding the necessary program for Windows 11 ARM. I am able to decode ham rtty and meteo fax, not DDK9. I belive that DDK and other from Germany weather service are not encripted, and on their schedule the class is reported as F1B, speed 50 baud, shift +/- 225 Any help? Grazie Roberto ===== SDR## 1921 Windows 11 running in Parallels Desktop MacBook pro M1Max Airspy+ HF Discovery (on line) Airspy R2 (on line) Airspy Mini (temporary off line) Spyserver: rob-casa-ge (dot) ddns (dot) info:5555 Airspy+ HF Discovery QTH Genova Italy nbrc.mynetgear (dot) com:5555 Airspy R2 QTH Breuil Cervinia (Aosta Valley) Italy

All, I'm trying to upgrade my HF+ Discovery firmware to 5.0.0, but am not able to. I keep getting the error shown in the window below. I've tried rebooting the computer, but no change. I'm running the flash.bat as administrator and running from the directory where it was extracted to. I've upgraded the firmware before and never had this issue. Help would be much appreciated. Damon

I am having an issue. I configured spyserver.config. See attached. But on spyserver my Airspy does not show up with spyserver running. But if I have SdrSharp running and go to the Airspy server web page it shows up. As soon as I stop SdrSharp it drops off the webpage. I am using the latest of Spyserver and SdrSharp. Windows firewall is not blocking port 5555. Router is letting port 5555 through. If I use a laptop through my iPhone hotspot and connect SdrSharp to my ip address and port, the same thing happens. When I am connected via SdrSharp via the ip address, port I have other connections being made from other ip addresses. What am I missing? Should Airspy server work and allow connections even though SdrSharp is not running? Windows 10 home. The ISP does not seem to be blocking the port forwarding. https://www.yougetsignal.com/tools/open-ports/ Shows the port as open. Ideas?

Greetings, I hope someone can help me with a few questions. Note the IF Filter + Notch Processor window and the IF Spectrum window shown on the attached picture. 1. Selecting Filter on the IF Filter + Notch Processor window, I can change the bandwidth (asymmetrically) even with the Asymmetric Filter check box in the IF Spectrum window not checked. I then presume that either window can accomplish the asymmetric function effectively. If this is true, then having the IF Spectrum window open is not necessary if the notch processor window is open. 2. Using either of the two windows mentioned above, how can I make a symmetrical bandwidth adjustment by just moving just one of the edges? If this is not possible, what is the way to make a quick symmetrical adjustment without having to enter it into the Radio window? 3. After making changes to the bandwidth, is there a quick way to return the bandwidth to the setting in the Radio window (in this example 192,000) without manually adjusting both sides? Thank you for any help. Regards, George, NJ3H Redmond, Oregon USA
