Vacation time ...

I am really close with the transmit. I am getting some interaction from the code that gets the ADC data for the forward and reflected power. Once this is resolved I will make a release that includes transmit.

I will be on vacation for a week now - skiing in Morzine, France.

More tansmit ...

Making some enhancements to the TX side.

Added the code to monitor the ADC for forward and reverse power and calculate SWR. Output power is controlled with the output gain control for the TX DttSP process.

Need to add the setup for the PA gain values for the correct power calculations.

I should be able to commit the changes in the next day or two.

Finally managed to get 100 watts output using a test tone. Found a problem with the SDR-1000 hardware code where the PA_BIAS control bit was inverted in the Linux code. This should now be corrected in the svn repository for DttSP.

Hopefully, I can now make a working transmit version available soon for others to test. I expect the CW transmit code will require a lot of work to get running well.
