Thanks for reply. You are right about SW broadcast ?images at certain hours. I made a short video, rx with no antenna, if you want to take a look.
Thank you!

Hi Adi,
The issue with the 7199 kHz birdie has nothing to do with the tuning clicks. These are complete different and unrelated issues.
Do you have your 'birdies' even when you disconnect your antenna? If you don't hear them without antenna then they are probably not birdies but images from strong SW broadcast stations.
At certain hours (especially in the evenings) I can also hear a lot of whistles, these are not birdies but they are images from SW broadcast stations, broadcasting in the 41m band (especially Radio Romania International and Radio China Int.).
It's hard for me to believe that restoring earlier software versions would cure your "birdie" problem, but if you want to try it you can go to
and download an earlier release. For all of these releases, make sure that you use the correct Si5351 library v2.0.1.
If you want to use Ashhar's very original version 1.01 please note that it only compiles with the old Si5351 library (v1), which you can download from
