Re: KerberosSDR Developments in 2020

If you're inclined to roll your own boards, this is the part I've used: https://www.minicircuits.com/WebStore/dashboard.html?model=HSWA2-30DR%2B If you would like to buy some, I'll be selling them through Tindie in a couple weeks. I've got most of what I need to make a significant number of these, ...

RF Switch Boards for KSDR

A little over a year ago I built some RF switch board to avoid having to disconnect the antennas every time I changed frequencies. There's been some interest from other users and I finally got around to making a large number of them to sell on Tindie. If you're interested you can buy them here: http...

Re: Major interference from computer

Is your desktop connected to the internet via ethernet? If not, you can just stop reading this post, otherwise, read on. Is that the only device in that part of your home connected via ethernet? What happens if you unplug the ethernet cable? What happens if you plug it into your laptop, assuming it ...

Re: Verbose mode disable

You're going to have to expand on this question a lot more. What software are you talking about? What's "talking"?

Re: Project: Trigger GPIO via SDR Received Signal

You could modify the python output of a gnuradio flow graph to use the gpio library. You'd just have to figure out the right place to put lines of code similar to this: gpio_error = None try: import RPi.GPIO as GPIO GPIO.setwarnings(False) GPIO.setmode(GPIO.BOARD) control_pins = (16,) GPIO.setup(con...

Re: KerberosSDR Developments in 2020

These switches you've used here look like an elegant solution to the programmatic disconnect-reconnect for syncing the kerberos. Sounds like it worked successfully which is great. Can you advise the part that you've used for the switch? Is this fork the same software you've used to control the abov...

Re: HackRf Woes

It sounds like you're trying to dive straight into the deep end without even testing the waters first. I can assure you that Pentoo has gnuradio installed, but going straight for Pentoo isn't the best idea. If you're looking for a more user friendly OS with some pre-built SDR tools check out DragonO...

Re: Still can't get KSDR working (Raspberry Pi 4)

That image should support everything the standard Raspbian image supports. Everything you're describing there sounds like a power issue with the pi itself.

Re: Still can't get KSDR working (Raspberry Pi 4)

Are you providing external power to the KSDR?
