Re: TX frequency? of uBitx at CWL and CWU mode #ubitxcw

The firmware is still the original for the ver. 3 Ubitx

I usually use a Softrock Ensemble as the receiver for the Ubitx and other rigs. The CW TX in the Ubitx is 700hz off the actual frequency. I believe it was done by purpose although I would have rather preferred it indicated the actual frequency.

Hi!

I would like to know whether the behavior of TX frequency of uBitx at CWL and CWU mode I experienced is normal on CECFW v1.08.

For instance,
When there is the CQ station on 7.0100MHz on my ICOM transceiver,  uBitx at CWL mode shows 7.0085MHz as RX frequency.
Then I transmit CW carrier on ubitx at the exact same RX frequency of uBitx.
CW carrier is observed not at 7.0100MHz but 7.0085MHz on my ICOM transceiver as RX frequency.

When there is the CQ station on 7.0100MHz on my ICOM transceiver,  uBitx at CWU mode shows 7.0100MHz as RX frequency.
Then I transmit CW carrier on ubitx at the exact same RX frequency of uBitx.
CW carrier is observed not at 7.0115MHz but 7.0100MHz on my ICOM transceiver as RX frequency.

This means that TX frequency is lower 1.5KHz at CWL mode and higher 1.5KHz at CWU mode than actual frequency.

Your comment would be much appreciated.
