Gang, In the June 2000 issue of CQ-DL, I noticed a new-product announcement by Symek GmbH about high-speed packet radios and modems. Example: TRX4S 430 MHz data transceiver with "wide-modus (audio: 100- Hz to 100 kHz bandwidth) for 76800 an d 153600 Baud FSK." Does anyone have experience with any of these products? 73, Paul, W4RI
