[TenTec] Omni 6+ Input vs Output power?

[Steve Weber]

The Delta II also reduces the drive automatically.

>>  Yes, the current consumption varies from band to band and when

>>  TELL YOU if you blow the things!

>>  With my Omni 6, I was not able to get 100W output on 3 bands

>>  Has anyone had a problem running CW at over 20A DC input with the

>>  20A for 100W rf out) are 160, 30, and 15.  I know this agrees
>>  with at least one other Omni 6 user.  Any more?
