Send me a photo of it. Have parted out two Omni 6s and may have one kicking around. Gary _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contest
Now that I have repaired the PLL on the 5.5 mHz board of this Omni 6+ I am repairing, I need to align the loop IF amplifier and VCO centering. Is there a resource where I can find this process? Gary
I did find the Omni 5 process that Barry had referenced but this only covers centering of the VCO. I need to do the loop IF alignment. There is a rectifying test point at the output of this stage and
First I replaced the PLL chip itself. Then I found an open 10 ohm resistor in the drawing line for the loop IF. I replaced that and also the BF988 IF FET. I performed a rough alignment of that stage
Actually the synthesizer in this radio is pretty simple by synthesizer standards. It is also rather ingenious. I have found that the CPU puts more of these in the parts bin than synthesizer issues. B
I am actually working on the 5.0 to 5.5 MHz PLL VFO. This is unaffected by the HF crystal aging issues. The VCXO on the board works fine. The issue is that the IF alignment requires relatively flat g
That board, sure I can use. As time goes on I am certain there will be more and more of these failing and it would be too bad to deep six a radio just for this board as it is really simple. I can fir
Thanks Clayton. Seems to be a common failure mode. Gary _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec
It took a while but I promised I would report on this after I had completed it, for the archive. This radio came to me with the 5.0 to 5.5 digital VFO completely out of lock and no amount of adjustme
Having just repaired an Omni 6+ 5.0 to 5.5 MHz PLL, I can see why many might like a simpler DDS offering. However, there is a dark side. Many of these do not use enough bits to draw the sine wave fro
The Orion 1 had LED illumination, one of the first Ham radios to do so, I have never needed to open an Orion 2 display but I doubt that Ten Tec would have stepped backwards this far unless they had a
I have replaced the LED illuminators with new ones fro LCD Parts. I am told that the same illuminators are available more cheaply but I have had good support from LCD Parts and they offer a drive boa
Loose connections are always a possibility. This radio is getting tot he age at which electrolytic capacitors are reaching end-of-life. They can cause many odd performance issues. The thing has just
Next time I do one I will document it in photos. Gary _______________________________________________ TenTec mailing list TenTec@contesting.com http://lists.contesting.com/mailman/listinfo/tentec
I am not certain but I believe that the Eagle carries both VFOs in each respective memory selection. Gary _______________________________________________ TenTec mailing list TenTec@contesting.com htt

I finally got around to the Argo 515. PTO ws about as locked up as any I have ever seen. I had to press the balls out of the vernier by tapping on the main tuning shaft to force the balls out of thei
I have about half a dozen of the correct Orion encoders. $25 each shipped. I also have one VFO encoder, $50 shipped. Gary w0DVN _______________________________________________ TenTec mailing list Ten

I just completed repair of an Omni VII for a fellow TT user. This radio would lock into TX whenever keyed and required a power cycle to unlock it. Reset process did nothing to help. I thought Id shar
