There is no way to trim the TCVCXO manually. It's included in the loop of a PLL for external locking but you can't control it directly. It seems that manual control was considered because adding a resitor can connect the control line to an aux DAC of the ADI, however it seems that the voltage might not be compatible and so you'd need external amplification to drive it. (that's from memory, might be worth rechecking schematics and specs) Cheers, Sylvain _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
