My experience is that 90 deg signal is enough good to build SSB signal using polyphase filter or experience SDR receivers. I have done one SSB tranceiver using this code and circuit. Here is some details: http://oh2btg.blogspot.com/2018/10/handheld-2-30mhz-ssb-5w-radio.html OH2BTGhttps://www.blogger.com/profile/16308885466013006010noreply@blogger.comtag:blogger.com,1999:blog-1399025129919394392.post-67378980860330481212020-11-01T22:53:40.315-08:002020-11-01T22:53:40.315-08:00Nice code!

You say the phase between the 2 outputs varies From 90 degrees over the tuning range of the vfo by about 3 degrees off 90. Was this uniform, that is was it something you could correct for if you needed pretty much exactly 90 degrees across the whole tuning range? My plan is to use the oscillator outputs to feed the multiplexer of a Tayloe detector. Do you experience any phase jitter in the outputs when you tune the vfo?<br /><br />Thanks, for sharing this code. 73 Tim VK4QPVK4QPhttps://www.blogger.com/profile/11340890537550169477noreply@blogger.com
