It would seem more likely that your reference oscillator is heat sensitive.This reference oscillator is a common failure in the Omni 6, particularly in the earlier oven stabilized versions. However,
I ordered several dozen of them. From now forward, if I have to go to the work to replace ONE encoder on any Orion I get through here, I will replace all of them. They are low cost and that is a good
In what position is that part? I assume it is Q9 feeding the mixer, U1. Q9 amplifies the sample of the crystal board going back to the login board. The PLL on the logic board sends a correction volta
i first cover the adjacent LED bond pads with Aluminum foil token them from getting hot. I then heat all of the pins at once using the small heat gun on my Hakko rework station. Once all pin bond sol
Looks like Garys has a little more drop-off than Fernandos. However, such loss of output is pretty common in may rigs. However, the difference between 65 and 100 watts output is not perceptible by th
Does anyone have the newer VFO tire for the Orion 2? One of mine is missing. Also, is possible someone has parted out an Orion due to bad CPU and perhaps may have a good looking pair of the cover? I
Drake TR7s were also famous for that issue. Part aging and, I believe, aging of ferrite materials in various coupling transformers resulted in drop of output, In the TR7, that drop was more significa
I just received the following unsolicited email FROM EBAY about the calibrator in question: Hello Gary, there's only one of these left! You recently browsed Crystal Calibrator Marker Generator 100, 5
You are correct about the thread regarding the various switching relays. They do fail causing lack of output. The fix is simply one of locating the defective one as there are several or each band. Of
Those four LEDs are common to connector 96. The LEDs share a ground one end of tat connector. Since all 4 are intermittent, I would focus on that ground connection, on both ends of the cable, and als
Hi Barry: I did install the new Bournes encoders. They work very nicely, as I had reported. However, the Multi encoder double steps (5, 7, 9 etc. instead of 5,6,7,8,9). I have located the encoder on
I am sure you already knew this but, sad personal experience told me that you must not run 3-500 tubes in any position but vertical. If you do, you will get the F-F short you got. Just a reminder in
I really cant figure out why no one thinks that the crystal oscillator board might be at fault, as I had suggested 2 weeks ago. This is the ONLY part of the radio that can cause a simultaneous failur
Well, your issue pretty well must be in the BFO. I believe the Omni 5 shares the same crystal in LSB and CW. I can repair Omni 5 radios. I have a parts mule and numerous spare boards so parts should
