After running a bit more tests on the VCO problem, I see that it is behaving more or less normally in 3 bands:
17m band the frequency at TP1 is 22917Mhz stable, DC Voltage at R30 : 3.49V for 18.000Mhz and 3.67V for 18.200Mhz
12m                                         20092                                           4.1V        24.800Mhz       4.43V      25.000Mhz
10m                                         23893                                           3.6V        28.000Mhz       4.48V      28.800hz
 
The voltages at R30 seem to respond ok on changes of the L30...
 
So the problem seems isolated to some but not the above bands. Any suggestions, ideas??
