Getting a WSPR, or >Digi signal of any kind on 1750 meters is fairly simple.. An HF >Tranceiver, run thru a Transverter, and into the traditional >Complimentary Pair PA will get you going.. Something to think about: A non linear final (such as Class D complimentary pair) is not suitable for transmitting a "Digi signal of any kind". Non linear amplifiers can be used for frequency modulated signals likeWSPR, WSJT, RTTY, Navtex, MFSK etc ... but not for amplitude modulated signals like WOLF, PSK, QPSK etc. Jay W1VD WD2XNS WE2XGR/2
