Sorry for the premature mail posting. I did some more digging and found a quite good
thread of information from around 2011 or so.

I note that Harald mentioned whether Marcin had suitable lab equipment and I was starting
to wonder this as well. Harald, you suggested Racal 6103 or similar, spectrum
analyzer/scope up to 900/1800/1900 MHz. I'm wondering if you have any more current
recommendations for equipment. I would imagine I might use an RTL-SDR possibly to
receive/monitor TX. I see Racal 6103 devices for around $100 on ebay so I could get one of
those if need be.
So I found the uboot sources and looked through and see board/mtk/sciphone_g2/mt6140.c
which has the rf_tx <arfcn> uboot command. So I'll check fernvale/mtk6260 and
see if similar code could be made for fernvale.
