"There is a lack of options really. I am really trying to move on try and get a cellular connection working as that would provide unlimited range. Just strugging a bit with the implementation."

"I really enjoyed the report on your range testing of the XBee Pro 900.  Do you know if anyone has tried using more powerful 900MHz transmitters?  The FCC limits in the US for the 900MHz band are 30dBm (1 watt) transmitter output power and…"

"Anybody have any experience with reducing vibrations when running larger 2-stroke engines in the range of 120cc plus?"

"sorry, i think you are right, its 50mW"

"Very good information, thanks for that.  I know you said it was a 60mW, but the one I was looking at http://store.diydrones.com/XBee_PRO_900_extended_range_module_w_RPSMA_p/br-0015-01-xbeerpsma.htm  states a 10km range and it is a…"

"Here is my writeup on my experiment... http://www.diydrones.com/profiles/blogs/what-is-the-maximum-range-of-an-xbee-lets-find-out  "

"it depends which Xbee you are talking about. I was using the 60mW PRO 900. Any 900Mhz patch antenna would do. Just do a local search for "900Mhz patch antenna". The key is keeping the antenna cable as short as possible so ideally attach…"

"Wow, for some reason I was thinking the max range was under a mile.  Is this because you are using a patch antenna?  Also, where can I get the antenna you purchased?  Thanks."

"I tested and it dropped out at the rated max range of 10km using a 14dBi patch antenna."
