Dear Martin, LF Group,Provided you were happy with simple on/off keying, i.e. QRSS rather than DFCW or the various mFSK modes, there is no need to interface the sig gen to the PC. You could just connect the sig gen output via a relay or other bit of gating circuitry, set the generator to the frequency you want and key the relay with the QRSS software... Actually, for most types of TX, a better idea is to leave the generator going constantly and key the PA stage. I used to use an old Racal generator in this way. Cheers, Jim Moritz73 de M0BMU |
