>> >> Senao 200mW >> ^^^^^ >> Really 60... 100mW I tested a couple of cards with an spectrum analyzer and them had a 20/21 dBm output power. The cards are installed with coolers to prevent a drop power problem that I read about the Senao cards.
>> >> 24dBi antennas >> Grid ? Yep. >> >> 72m & 60m towers >> Rx_level = -115 -20Log(36) +20 +24 +24 = -78 dBm >> Use only fixed speed, >> for example: only 5.5M or 2M or 1M I don't need to do that, because the boards work on 11M and stay there without problems, the Senao sensitivity is -89 at 11M. Anyway, I try on 1, 2 and 5.5: same problem. Change RTS values: same problem. Change maximum number of retransmission: a liiittle better, go up from 0.08 to 0.3 MBit (wow! :). >> >> Senao 200mW >> >> 1W amplifiers >> PC_card 200mW + 1W amplifier NEVER use !!!!! >> Amplifier is overloaded !!! We are using Teletronics amplifiers, and they supports up to 23dBm on the input. And we are throttling down the transmit power a little. Really, I don't believe that this be an RF problem. Do you know anyone that have a >35km link with Prism chipset, without special firmware or drivers? And of course, with a sustained >2Mbit bandwidth. Thanks!
