I forgot to add, the reason why 9m MHz IF radios automatically select LSB on bands below 9 MHz and USB above 9 MHz is that, back in the 1960s, 9 MHz was a very popular IF because the manufacturer cou
Does the fault occur on all bands? Does the frequency shown on the display change when you tune the VFO knob? The display in the Omni VI is not a counter. It simply reads the data going to the two PL
One more thing - try resetting the CPU. You do this by unplugging the radio from the power supply. Then remove the 2032 battery on the cpu board. Wait at least 30 seconds, then put the battery back i
I would suggest that the TDA1015 has failed. This would be the same as if one of the transistors in ay complimentary symmetry audio stage went open. Youcan test this by checking voltage on pin 2 of U
Thats a common problem when ceramic capacitors become a major part of the tuned circuit because ceramic capacitors (especially doorknobs) have very high TCC (temperature coefficient of capacitance).
I have an Orion 2that I am considering parting with. It works perfectly, has had the power distribution board upgrade done, CPU battery replaced, all new function encoders, 1.8 MHz SSB filter include
If you DO try to repair the old display, be sure to keep the orientation of the actual display by marking it. There are no markings on it indicating orientation. Changing out the cables is a nothing
While searching for info on testing some new electrolytics, I found this exceptional site describing, in readable terminology, everything you ever wanted to know about aging, reforming, leakage etc.
Those cheap DDS devices do not use sufficient bits of data to generate the sine wave output. This gives rise to severe quantization error, resulting in a sine wave that looks more like a sign-ish sta
If the AGC is working, you will not be able to easily perceive if the signals are weaker one one versus the other. You need to compare the level of a given signal versus the noise level adjacent to t
I have a Ten Tec Orion 2 for sale. It does not have the auto tuner but it does have the 1.8 KHz SSB narrow filter. It comes with the Ten Tec hand mike. It works properly on all bands, all modes. Cosm
From your description, it sounds like something in the synthesizer. It is not immediately apparent what part on the receiver board itself could cause that. However, I do have a spare sub receiver boa
If your band scope produces peaks that air near saturation, you have a problem that would not be corrected easily by an adjustment. I have an O2 with the latest firmware and it does not have this iss
