Hi,
the possibility of using SPE 1K-FA also in the 60 m band, since the manufacturer blocks this option in the frequency table and does not allow its use. I have Yeasu BCD CAT data set, and for transmitting in the 60m band, I send the BCD combination for the 6m band to the SPE! I adjust the ATU in manual mode for the second antenna and that's it.
