First, does it only on a few select bands, or on all bands? If one or two bands only chances are it is a hetrodyne crystal that has aged and is going out of lock. Some of those crystals are used one
That warbling can also be caused by a HFO crystal that is trying to phase lock to the master oscillator. The PLL will sweep the oscillator loop voltage trying to achieve a locked condition. I've had
Further Notes: To access those crystal slug tuned adjustments you will need to lift the aluminum cover. You can disconnect all of the cables for the FM board, and any RF connectors. The exciter board
I'm looking at a Jupiter with a damaged display panel and other panel control issues... I was considering grabbing on the hunch I could use like a Pegasaus, under WSJT-X or using N4PY control program
Was a fan kit ever offered for the Omni V or VI series rigs? I am starting to dabble in digital modes and suspect some cooling might be a good idea. Pete W1BR
My guess is you have a bad encoder, or a bad switch on the front panel. If one of the switches controlled by the push buttons remains keyed it will raise an interrupt in the software and through the
If the Omni has provisions for an external receive antenna, the first thing I would do is select the external RX antenna, and put an antenna on that RF connector. If the problem clears, then I'd look
I have all of my slots filled with Inrad filters in my main Omni VI Plus rig, and that includes both Inrad roofing filters. To answer directly, I have both 6 and 9 MHz 250-Hz Inrad filters installed.
If the same segments are missing on several of the LED displays the suggestion to clean and reseat the board interconnections and related cables will probably solve the problem. Those displays are mu
They were listed the other day on the TenTec site, but now the only place I can find them is where they are listed is by color as options for the new Omni VII. Price is around $17.95.
A birdie told me that Mike is showing the new Omni VII Plus at Hamvention. Street price is $2999 according to rumor. Radio was said to be in production. That might be a bit high compared to imports,
If anyone has a scrapped Omni VI I need a few odd parts. First I need the four pin Molex power connector that is attached to the rear apron. I could also use the metal shield over the PA assembly and
Carlos It is the same signal path that feeds the RF input to the Ten Tec receiver section. I use mine for my K9AY loop antennas, which have a preamp. The isolation is the same for the TenTec transmit
Buzzing relays sounds like a problem on the processor board. But, I'd reseat all of the connectors associated with the band pass board first. As I recall, that starts on the micoprocessor board, and
Lamp intensity is controlled by the logic board. First thing I would check is to see if the 20 MHz oscillator is generating time base signals on the 7474 divider. Next, I would want to see clock puls
Greg U13 will not cause the problems you are seeing. It phase locks the HFO crystals to the master oscillator. If it is not locking, all that will happen is that rig will be off frequency on that ban
Greg... Maybe I misunderstood the problem. What is working and not working?? You mentioned the front panel controls are working? Is it just the LED frequency display and meter lamps that are out?
I would be interested in picking up a junker Omni VI Plus or Opt 3 for parts. Not worried about case, front panel or PA condition, but prefer a unit that is likely to have good CPU, VFO and crystal m
