Good Morning Group.......
Regarding my earlier E-mail (below) to the group on my low RF power output
(85W) from my Omni VII, I have determined the following after trying several of
your furnished thoughts/ideas:
* One of you suggested that one of the Molex pins in the DC power connector
cable might be a little loose and causing a voltage drop. Sure nuff', the
positive pin was slightly deformed and the pin was replaced and power increased
but only by appx. 3 watts.
* I contacted Stan Brock at T-T via E-mail and he advised I contact Garry
Green, the tech at T-T that works on the Omni VII.
* This morning, I spoke with Garry Green on the phone and he advised me that
early on in production, several Omni VIIs went out the door with the RF power
set on the low side. (This does not explain why mine measured 105 watts when it
was new.) Garry explained that if I would send in my Omni VII, he will reset
the power output. He also explained that there is not a single control that
sets the RF power output. As it turns out,resetting the RF power is not all
that simple as the operation is contained within software/firmware and requires
setting the RF power on EACH band!
Thus, I will send my Omni VII back to Garry at T-T after the XMAS package
traffic rush dies down.......using my Jupiter in the interim.....
TNX AGN for all your ideas.......

Omni VII-ites'
I have an Omni VII that is appx. 2 years old. Over time, I have noticed a
gradual decrease in RF output power.
With 13.8 VDC measured at the radio power connector, the Omni VII digi-panel
states: "Power 100W". Yet, when the RF output power is measured with a
lab-grade 50-ohm load and either a Bird 43 or a calibrated oscilloscope, the
measured RF power is actually on the order of 85 watts output, regardless of
band.
I suspect I have an aging component sitcheeashun'..........Is there an internal
control to crank the RF back up to spec??
TNX in advance for any feedback.........
