Hi, Todd-- Here are some of my musings on your comments: Those sad fellows' troubles are obvious: they want to consider themselves "professionals" instead of "amateurs." I'm glad they sent the rigs b
And to further complicate things, I can assure all of you that the Orion will NEVER be finished. Somebody will always be coming up with a modification that you can download and install without taking
it didn't come out of the rig 73, Mike N4NT I recently came into a good deal for an Omni-C, matching VFO and power supply and so picked same up. When the boxes were unpacked, I noticed a 2N2222 trans
I respectfully suggest you call Garland Jenkins at the Ten-Tec service department. Know just what the display is showing on different bands/frequencies. If Garland can't tell you right off, he probab
Yes, if you will read the manual, you'll find that you switch to some band and turn the preselector all the way one way. That lets you receive WWV at 10 MHz. Then you set the counter timebase so the
Stuart, what you are saying is misleading. There is a core that is sliding into and out of a coil. But it does not make contact with the coil. It is nothing like adjusting a slug-tuned coil. 73, Mike
The Century 21 PTO is probably about the same. Here is a website about rebuilding its PTO. http://www.io.com/~n5fc/c21_pto.htm I'd appreciate it if you did as you indicated and posted photos of your
Here is an email I sent privately to a fellow today. It speaks for itself and I stand by it. ___________________________________ Take a different rig. My Omni-C puts out spurs. Even with the KEY UP,
Sorry that the below message is ambiguous. It is on 17 meters that my Omni-C puts out a couple of watts of garbage KEY UP. I have never had any trouble with that rig on any other band. When the Omni-
About the strength of the spurs: my Omni-C on 17 meters put out 100 watts key down and 2 or 3 with the key up. Assume best case, the difference between 100 watts and 2 watts of spurs is 17 dB. So the
The 280 does have the crowbar circuitry. It also has current limiting. It is about the same circuitry as the model 255 speaker/power supply that matches the old Omni rigs. In color, it does match the
On page 2-6 of my 544 manual under "General Operating Notes" it tells how to receive WWV on 15 MHz. 1. Set Band Switch to 21.0 MHz. 2. Rotate main tuning dial so that the frequency readout is 21.000
Before I did a lot of trouble shooting on that Century 21, I'd make sure it was connected to a proper aerial and see if the birdies are still audible. Testing for birdies with no antenna connected gi
I don't believe you have sufficient grid current. The grids of 3-500z tubes when the tube is cathode driven normally draw 108 mAdc each. That is 216 mAdc for a pair. Where did the 130 ma red line com
