Re: RSP2 LO 3rd harmonic spurious response only -20dBC

Thanks Andy for your tip for RFSim99.

It's easy to get learned and fun to play with.

Re: RSP2 LO 3rd harmonic spurious response only -20dBC

Andy, as you seem to be experienced with external filtering, can you possibly recommend a solution for me: For listening MW and 160m I have a Double-KAZ antenna, with about 1 kohm impedance, symmetric. It's fed to the RSP2's Hi-Z port by using 12 meters of 450 ohms ladder line. I'd like to add an ex...

Re: RSP2 LO 3rd harmonic spurious response only -20dBC

Hi, I have experienced the similar, but haven't taken such an analytical approach on that as you've done. Could you possibly share some more details, Sir? - Did I calculate right, that when you are tuned into let's say 1.8MHz (Zero IF), you are also receiving signals which actually are at around 7.2...

MW-antenna directional during the nighttime, omnidirectional in the daytime

There exists several directional mediumwave receiving antenna concepts based on an idea that the directionality is optimized by 'tuning' an end-resistor for the best achievable Front-to-Back (F/B) ratio, and after that usually replacing it with an equivalent fixed resistor. For example Beverage, EWE...

Re: Automation/remote control?

Hi agn, to get RDP working you don't need to tamper the firewall in the local end, but in the remote end yes. - You need to allow incoming TCP and UDP traffic towards port 3389 (default). - And you need to map/route/pat/redirect (whichever term is used) that traffic to the particular remote host com...

Re: Automation/remote control?

Hi, interesting use case you have:) HDSDR can perform scheduled recordings nicely. I hope that some day also SDRuno will. I operate remote-only. Even if i'm at my summer cottage (my remote site), i need to operate "remotely", and i've also done that from 10 000 kilometers distances. For wi...

Re: HDSDR and storing/loading profiles

Hmm i'll try to make my clumsy question a bit more clear:

Is there a way to start HDSDR with a specific set of ExtIO parameters - with different values from which were used at the latest HDSDR session?

HDSDR and storing/loading profiles

Hi, i know how to save and load ALMOST all settings of HDSDR in a profile using command line parameters. It is done like this: "C:\Program Files (x86)\HDSDR\HDSDR.exe" "-p" "MWREC" BUT, is there a way to save/load also the required set of ExtIO parameters, like IF Bandw...

Re: SDRuno suggestions...

In my wish list the number one is a Recording Scheduler.

In HDSDR it is implemented in a great way.

Also I would like to see a command-line parameter to start an immediate recording.
