REPLY: Good point, but the way I plan to use it it should work. I want to run the IC-7500 in RTTY mode with a 300 Hz bandwidth. I'm guessing that bandwidth is narrow enough for 2Tone to lock on and thereby generate a signal that is not too far off of 2125/2295 for FSKit to operate correctly. There is another problem I just thought of however. Having AFC on while S&P'ing and using FSK is not good. I'll have to think about that a bit. This might not be doable after all. 73, Bill W6WRT _______________________________________________ RTTY mailing list RTTY@contesting.com http://lists.contesting.com/mailman/listinfo/rtty |
