Airspy Discovery Sample Rates Supported

#1

Unread post by pauldbnut »

Currently, sample rates for the HF+ Discovery are limited to a range of 192 to 912 kHz.
Occasionally, hunting for weak signals, a very low value (e.g. 32 kHz) can be useful.
Would anyone else be interested in this addition?

Paul,
If you create a server, you can get all the way down to 30kHz.
Since mine are anywhere from 1 foot to 9 miles away, I operate all of them via the server feature. I can even operate the two SDR's connected to this computer (KA1GJU Super Station #1) as a server. Here are my bandwidth choices, see attachment. You can make the server public or private, you just have to create a guest account and place a guest account name and password in the "On Air" tab of the server manager. Buried in the files section of the groups io site is a pdf I created on how to set up a server.
See pg 17 and beyond of this pdf:

Kriss, thanks for your reply. Most interesting!
Exploring the server capability has been on my job list for ages.
Trouble is, every "plat du jour" lasts more than a day.
Maybe I should get my priorities right :)
Best regards

Well Paul,
We can ALWAYS use more servers on the netwrok, especially ones that the sysop is proud to have. Such as quality SDR's and decent antenna(s) that hear real signals and not the local HE clothes washer, variable speed AC motors, solar panel micro inverters, etc. Nothing beats lots of wire up high, draped across the tree tops in my case.

"We can ALWAYS use more servers on the network..."

Kriss, my current location is (sadly) one of the worst you can imagine - so would be of no use to the community.
But I took up your brilliant suggestion and it works perfectly, as you said.

That's got me thinking about an old RPi gathering dust, whether the guy on a large property nearby might host it for me.
May need to think about some heavy-duty battery storage...

supporting 630 and the divisions of 630 is highly recommended. for 630, the DSP is done on the radio and all the sub-divisions are by two.
