- Three mentions of this wonderful piece of work by JF3HZB is THE gag level. So, this is the last you will hear about it.
- Some final comments. This is not a project for an appliance operator with no experience in using the Arduino IDE. It is an advanced piece of work! The entry cost in terms of dollars is low but it is a mountain high in terms of getting it to work -- properly.
- Some of the challenges included that CLK1 was activated with the same LO frequency as CLK0 only 180 degrees out of phase. I thought I was seeing some signal spill over and so had to figure out how to NEUTER CLK1.
- The next two problems were that the BFO was not being generated at the proper frequency. While the data entry was correct for LSB, the correction of the Si5351 clock was a bit more challenging. I resorted to using a frequency counter and a couple of tries got me to the proper LSB value (with sideband inversion). So, now it sounds good on receive and the signal sounds good on transmit.
- Because of the diddling with the BFO that then was a factor in setting the LO frequency and the offset needed for the correct dial reading. That also took a bit of fiddling.
The Final Step was to change some of the display colors for better readability.
Them that know can make it go!
