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.

Re: Propagation-triggered recording

Hi, here comes two oneliners. In windows-environment they need GnuWin32 Coreutils, Grep and Wget to be installed. Check your paths. The first one kicks HDSDR I/Q-recording running, if Kyoto Real-time DST index rises to value of 10 or above: wget --no-cache -O - http://wdc.kugi.kyoto-u.ac.jp/dst_real...

Re: Propagation-triggered recording

Ok ok, I have made some experiments with, hmm, artificial decoding of CW. When comparing JT-modes and CW as propagation indicators, I think the key differences are: - Geographical coverage of CW is better. There is not much digital signals on 1.8MHz from let's say Northern Asia or Africa or Pacific....

Propagation-triggered recording

(Look for new fall 2017 version below...) Hi, i have made a set of scripts and other files which can be used to build a system which monitors JT65/JT9 (digital modes) amateur radio traffic on 160m/1.8MHz band, and if nice propagation to area you are interested in exists, a MW-BC-band recording is st...
