I recently purchased a used Omni VI that quit transmitting, sent it in to TT for repair and alingment. TT replaced the finals and some other work... I recieved the repaired Omni yesterday and wasted
Hey, 'D', tell us the type of power supply, eg: linear, switching, etc... also, what is the ripple voltage and frequency at this 35 amp load... Also, is the Omni on SSB or CW or AM while failing. You
Good morning once more Denton, my inquiring mind is starting to focus on your 'supply' which is starting to sound like a non-filtered charger, hitting the batteries at 35+ amps on positive peaks of a
The power supply is a linear one...with over 200,000 microfarads of filtering, with tight regulation. The Omni was in cw mode when it failed, and the amp meter on the power supply indicated about 14
ok see privous reply....I just sent it off... also the Omni, Ft 990 and uhf/vhf rigs are always attached to the battery output..with a fused B+ TT gave me indication this morning that their power sup
Here are some other things I just remembered... When the Omni quit on me the first time, at TT's suggestion I did some signal tracing... Using the 'scope, I had signal ampflication until the driver t
Looks like you're getting plenty of feedback concerning that oscillation. My first thought was "what bloney!" Then I realized I had misspelled bologna. Really, when it comes right down to it....You c
TT said they would repair the Omni again for no cost to me....I didn't inquire about shipping, but am sure glad I have my Ft 990 for a back up rig..... It keeps chugging along..... I suspect...and it
Can you borrow one locally "D", if you blow up the rig again,,,,that would really counterproductive wouldn't it...Good Luck Guy and hope you find the problem,,,,,Mac TT said they would repair the Omn
Hi to all-- Perhaps there is over voltage spike generated. If you connect a 1.5KE15A diode across the supply line( band to positive lead) between fuse and rig, the spike will be clamped. The fuse wil
I can't help you with the oscillation but the following describes some of the final transistors used in the Omni VI! http://lists.contesting.com/_tentec/2002-12/msg00387.html 73, Rick VE7TK Website:
Not sure about the "oscillation" thing in the power supply, but Ten Tec radios do not fold power back under high-SWR conditions and depend on the Ten Tec power supply's ability to limit current supp
The Paragon, Paragon II, , Omni V, Omni VI, Jupiter, and Orion all have a circuit that reduces drive if the current in the finals goes above a threshold. This circuit not in the original Omni A, Omni
That's what I was thinking. Short of putting a recording oscilloscope on the supply leads, I would buy their "official supply" and run it that way after it's fixed. Then you will have sorted out the
14.2 vdc is the power supply's output at its terminals...it then goes thru a blocking diode with about 6/10th vdc drop at the batteries. -- Original Message -- From: "Carl Moreschi" <n4py@earthlink.n
The tech didn't say anything to me about excessivent current....and if that is what happened, why didn't the fuse in the back of the Omni blow? -- Original Message -- From: "Vic Klein" <vhklein@ptd.n
Fuses are relatively slow acting devices and may not respond to instantaneous blips that could cause a transistor to fail. Typically, in my experience, a fuse blowing protects you from a fire after t
