Likewise I am thinking it could be your BFO setting - mine was way off when first delivered.? If you listen carefully to SSB you might come to same conclusion that it may need an adjustment.? Instructions are available at HFSignals - BFO adjustment tends to be easier than frequency calibration.? also see this guide at my local club:
??? ubitx calibration INSTRUCTIONS
Raj also brought up the topic of spurious - I have a v4 also.? In a typical v4 there are spurious issues in some of the bands, generally not much more than 10 dB out of compliance.? In mine I installed a circuit board containing a set of 3 relays, to separate input and output relay function.? it fixes spurious at 18 MHz and below (unfortunately the board and kit are not for sale anywhere yet!? I have dropped hints to ubitx 'merchants' to sell it).? my rig was okay 'as delivered' on 80 and 20 meters.? (I have not yet solved spurious above 18 MHz - they are from a different source - Raj I remember uses better relays and some shielded inductors - I am not sure what else.? I am wondering how the shielded inductors will work in conjunction with my relay solution - I need to get some to find out!? other fixes did not work for me without reducing CW output power).?
Enjoy your ubitx - I recommend 20 and 80 meters from what I have experienced with my rig for spurious. ??
