Re: SDR's?

I'd also be interested to know if anyone has attempted to build ASL3.

I believe getting the PTT/COS working on the CM108 device could be interesting.

From a fellow ham thanks for the information.

On another note anyone tried to build Allstarlink on OpenBSD?  If not any other repeater controller software?

  I don't have one but I believe hackrf has a bit of support. There  are a couple of other relevant things in ports, however in general  you're probably better off sticking to Linux for this. SDRs usually  want userland support for USB devices and that doesn't work well in  OpenBSD.  
  I have a bucket of SDRs i've tried on OpenBSD. The rtl-sdr does work  under OpenBSD, but the USB stack is particularly fiddly which is a  recurring source of weird hard-to-debug issues.    I've tried a rtl, hackrf, usrp (b210, b200), airspyhf, and a few others,  and the only which I had any meaningful luck with was the rtl. I  wouldn't suggest this route except in so far as you're looking to  improve the codebase of the SDR libraries or brave enough to work on the  OpenBSD USB stack.    I sent a patch to USRP upstream that fixed building from source a while  back, so the USRP library *can* work well enough to get metadata back  from the radios, but it won't actually work because (I think?) of the  usb transfer code.    I posted a while back[1] after digging in a bit to what was causing the  USB issues. I did not isolate the cause, nevermind fix it.    I still process some RF data on an OpenBSD (mostly for fun/sport) -- but  the only reliable way is to run the radio on a Linux box, and serve IQ  over the network. OpenBSD's network handling code compared to the USB  handling code is a lot more ... robust.    Fondly,    paultag    K3XEC      [1]: <ZCHKm9h7YYQiE4Uc@nysos>
