"Also I talked to my local radio shop yesterday and the tech looked at the FCC regulations for that band (902-928) and there are no power restrictions."
In fact, there are many restrictions on the 902-928 ISM band in the US and Canada.
Ensure your radio tech is familiar with the FCC rules:

Section 15.247 Operation within the bands 902 - 928 MHz
===================================================
(2) For direct sequence systems, the minimum 6 dB bandwidth shall be at least 500 kHz.
(b) The maximum peak output power of the transmitter shall not exceed 1 Watt. If transmitting antennas of directional gain greater than 6 dBi are used, the power shall be reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi.
Note the FCC view on external amplifiers for Part 15 transmitters:
http://a257.g.akamaitech.net/7/257/2422/16nov20071500/edocket.acces...
"Can an optional amplifier accessory for a Part 15 device be certified as a separate device under Section 15.204(b) ?
No, if the transmitter was originally granted without an amplifier, you must file a new application for the device and any transmitter/amplifier option, as stated in Section 15.204(b). In no case can the amplifier be authorized and sold separately, except, as allowed in Section 15.204."
Be careful about what amplifiers you use. If you start blowing your neighbors autosteer systems out of the field with boosters, someone may complain. There are fines not to mention the loss of your investment in equipment.
To go above 1 watt you may need to go back to licensed 450Mhz if you want to burn through trees.
Again, get an experts advice first. | |
