Ron,

Please check the output (scope and freq counter) from the 5.0-5.5MHz PLL. 
Since it's dropping out on all bands while tuning the 5.0-5.5MHz oscillator, 
I suspect that you are losing output from the synthesized vfo.  If you can 
confirm that behavior, you can then dig deeper.

I'm not very familiar with the Omni V, but I would think that the PLL 
synthesized vfo is similar to the Omni VI.

73,
Jack K1VT

Hi Steve and Others

I have am Omni V that dies if the ambient temperature goes above 25 C (77
F).
Mine dies on all bands. It dies on the low end first and moves up  the band.
A further warning of trouble is that  the sigs. both RX and TX have a rough,
choppy sound.  One suggestion was to recap the rig and\or use a TCXO
in place of the MO.
