INRAD sells a suitable 500hz unit. They also have a 300hz unit. I am leery about the 300hz filter being too narrow. Any opinions?Chen will chime in, I'm sure, and will have the most accurate answer, but I think the "optimal" width for 45.45-baud 170-Hz shift RTTY is 350 Hz. _______________________________________________ RTTY mailing list RTTY@contesting.com http://lists.contesting.com/mailman/listinfo/rtty |
