Go with a transverter and use a 10 meter IF.?

I have seen dual band 2 meter/432 MHz transverters out of the Ukraine or options such as Elecraft. Down East Microwave also sold vhf and uhf transverters but I believe they spun that business off to another builder.?

Or find a used one on the auction site.?

I have picked up the complete Elecraft line 6, 2, 222, and 432 used except for the 222 I’m building and driving with my Kx3 or dedicated 10 meter IF radio?

Looks like the goal is to build something more challenging than the uBitx.
Beyond that what it is or does is totally up in the air.
Discussion seems to be moving toward a single band rig capable of SSB/CW about uBitx size.

A few thoughts of my own:
Phase noise from that si5351 gets worse as the freq goes up, maybe an si5338 or si5341?
Having all oscillators off a single reference makes calibration much easier.
Could be used for cross band ops if it receives on more bands than it transmits.
A wideband receiver could also be a spectrum analyzer, use digital techniques
on the audio when resolution better than the crystal filters is required.
Transmit mixer, drivers, final could be a separate board for each band desired,
zero transmit boards is an option for receive only.

I'm lost as to what your goal is here.
1. The baofeng won't do SSB. Are you wanting to build a SSB unit or an
FM unit?
2. Are you thinking of a handheld or a desktop?
3. a phase line at 432Mhz won't be correct for 144Mhz. Are you thinking
a two-band unit or one-band unit?
