Hi all,
Just to let everyone know - in addition to working on manufacturing issues we're improving our UmTRX firmware and software support right now. And today we've got dual-channel finally working. Thanks to Andrew Karpenkov for his awesome work on implementing the second channel support in FPGA!
I plan to push the pre-built FPGA image to the download area in the during the weekend and Andrew will publish the FPGA code changes soon too.
What's ahead of us is to teach OpenBTS to use the second channel of UmTRX. This includes support of two independent channels and then implementation of switched diversity receive.

Hi all,
I've published the pre-compiled UmTRX firmware with dual-channel support in our downloads area: http://people.osmocom.org/ipse/umtrx-v2/fpga_bitsream/2013-02-03-394f48b7/ UmTRX LEDs new indicate Rx/Tx on both channels independently - LEDs A/C indicate Tx1/Rx1 and LEDs E/B indicate Tx2/Rx2: https://code.google.com/p/umtrx/wiki/FeaturesAndTechnicalSpecification#UmTRX...
Note, that you have to use the latest 'fairwaves/umtrx' branch of our github repo on the host side for this firmware to work properly: https://github.com/fairwaves/UHD-Fairwaves
