@cpixip thanks a lot for your work on this stuff; it's given me a leg up.
I have 2 of the "1000 meters distance NRF24L01 + PA + LNA wireless module" (As translated from the Chinese...) coming; we know Mr. Tang who runs this TaoBao (Chinese Ebay) shop.
Take a look here: http://item.taobao.com/item.htm?id=9107958905&frm= (Chinese) , but use Google Translate or run Google Chrome.
I like the idea that we have a transceiver that has 3 levels of price and performance with exact same software!
I THINK the prices will be something like $5 - plain nRF24L01 with PCB antenna , $12 with Power Amplifier +15 dBm - sma RF connector, $18 with Power Amp and Low-Noise receiver preamp, Antenna for last 2 about $1.50
But I want to get good working Arduino examples before I start selling these to the newbies and having people be unhappy...
I should have them in about a week....
