What about BasicTX, which does 1-250MHz?
The 250 MHz spec on the BasicTX is somewhat misleading. Although the analog portion (basically the transformer) is rated to that, the D/A converter is only running at 128 Megasamples/sec. Nyquist says I can only use that to synthesize up to a 64 MHz signal. Beyond that, I would have to under-sample and use one of the aliases. Essentially, to get 145 MHz, I would have to run at a lower frequency and try to use one of the upper aliases and a high-pass filter to get 145 MHz. Is this practical? Is there enough energy there to have a decent S/N ratio after filtering? @(^.^)@ Ed _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
