Hi John,
toggle quoted messageShow quoted text
well, UDR56K - sounds good and promising. Can I have few questions: - RF TX power 25W is for 100% TX cycle? No degradation or switching to low RF power level? - any additional cooling systems for 25W RF power and 100% cycle? - what is RX/TX time (TX delay)? Electronic or mechanical RX/TX switching? - RX: conventional or SDR (I/Q)? - bandwidth of I/F filters for different speed (switching filters)? Type of filters? - two points modulation (VCO + VC-TCXO)? - RX multisignal selectivity? - direct interface to TRX? - availability of description of internal interfaces? - kit availability? - do you plan to demonstrate any concept of UDR56K in Friedrichafen, Germany in June 22-24? Good luck with the UDR56K project! Karen, RA3APW
