bring your baofeng/handheld to activity day please

2023-07-14 Thread Randall Wayth
Hi all, There was an interesting thread on wahams a week ago about the spectral purity of Boafeng handhelds. I just measured mine using my specan, and it would be interesting to get a larger sample. I will bring my specan to the activity day today, so please bring along your handheld, and any adap

Re: [VOLK] a += b*c ?

Thanks for the suggestions and apologies for not being 100% clear at the start. I'm not looking for a dot product. I'm looking for a[i] += b[i]*c[i] specifically for floating point So it would be the equivalent of IPP's ippsAddProduct_32f. The application is to apply a window to a set of sampl

[VOLK] a += b*c ?

Hi Folks, Hopefully I am just missing this, but is there a kernel that does vectorised a += b*c ? Something like the IPP "AddProduct" function? Cheers, Randall.

[Discuss-gnuradio] receiving data from two rx boards on USRP simultaneously

2011-01-24 Thread randall . wayth
Hi all, I have a shiny new USRP with two dbsrx daughterboards installed. We want to use this as a demo for a 2-element interferometer. Ideally I just want to capture the raw data, with something like the usrp_rx_cfile.py program, where the samples from each board are interleaved. However,

[Discuss-gnuradio] status of USRP2 on Mac

2010-11-25 Thread Randall Wayth
Hi, I'm wondering if someone can tell me the status of using a USRP2 with a Mac. I found an email on this thread from July 2010 saying that it needs UHD support (whatever that is), but version 3.3 has since been released. The wiki page for Mac install under "getting started" ( http://gnuradio.org/
