Ron, what your friend originally asked is full of mis-information.
What Clayton just posted is essentially true. According to the wiki,
the Omni VI and early VI+ used a xtal oven. Ten-Tec switched to a TCXO
in the later VI+ because the oven was no longer available to them. The
TCXO was available as a kit to retrofit earlier units with failed
ovens. But a proper functioning oven should have had equal or better
stability than the TCXO, so it really wasn't an "upgrade".
