[Elecraft] RS-232 over WiFi

[Walter Underwood]

If you want something that is designed for rig control over wi-fi, get a Piglet from Pignology.

Also important the level of interference in ISM band, the modulation for BT devices is GFSK, DQPSK and DPSK, the good part is the BT protocol is designed to avoid 802.11 b/g/n/ac and can go up to 2485Mhz and at least for NA the upper freq is ch 11- 2462  as central freq so at 30dBc you'll get 2473, so there is some free sectrum room to avoid house interference from wifi equipement (in EU I think can go up to ch 14). The BT  BW is 3Mhz as far as I remember plus the protocol is close to FHSS one. However the biggest BT killer are the 2.4Ghz wireless phones, try to avoid this at home (I witched with DECT ones). Having a free of interference spectrum will
> "extend" the coverage coz the RSSI on wifi devices is not an absolute value (is a long story with wifi/BT rx calibration) and is enterily based on SNR, if there is an interference the BT device will "report" a lower RSSI and will decrease the modulation scheme. In my HF shack I had no problems with HF interference (no wonder the spectrum is faar away) consider mounting this gizmos with external antenna in a pair config and do not relay on internal computer BT card....my two cents
