Don't know if you are aware of them but Almost All Digital Electronics (AADE) sells some frequency counter/display units. You can check them out here: http://aade.com Specific information for use on
Actually I believe the AGC is audio derived. That is why the audio CW filtering works so well. The ALC limits the transmitter output. Full clockwise sets the limit at maximum. It decreases as the ALC
I don't know for sure but can tell you that it uses the same mixing scheme as the black Omni rigs. Those rigs will not properly work 17 meters because they use a 9 MHz IF. The local oscillator operat
The 262 and that genre did not have a crowbar circuit to protect your equipment from overvoltage. If you have a circuit failure in the supply, you are likely to get 25 volts output to the rig. Ten-Te
The Argosy rigs also came stock with a 4-pole SSB filter (9 MHz), just as the first Corsairs did. Replacing the filter with the model 220 8-pole made a huge improvement in the Argosy, both on CW and
I'm not sure but would think it operates like the analog dials on the rest of the Ten-Tecs. If so, the dial's movement depends on an elastic "bungee" section of the dial cord. Over time, that elastic
I had a protracted exchange with a fellow whose Argosy was bothered by broadcast band transmissions. His trouble may have been from the standard AM broadcast band. He resolved the trouble by adding a
The basic microphone was a model 700, methinks. It had no connector at the rig end. Two other versions were available (like the 701 and 702 but probably not those numbers) that had connectors. One wa
would a vacuum cleaner help? I need some advice on something that is pretty basic. I have a new Orion, but find the dust buildup on the outside of the black case really shows up. How do you handle th
I doubt if this is a correct statement. It is much as realizing that the more foolproof the product is, the more clever are the fools who use it. 73, Mike -- Original Message -- From: "Grant Youngman
Someone else can tell you the procedure. But I wish to alert you to a potential problem. The 252G and supplies of that genre did not have a crowbar circuit. This means that if the pass transistor sho
Know that you will need to add a circuit to switch the filter into the circuit. There are probably many ways to do that. I've seen a small toggle switch added through a little slot cut into the front
That's right. And Bill Gates said that nobody would ever need more than 640K of RAM in a computer. N4NT Last evening I looked up the QST review of the ORION II and found something of note from a cont
The Omni-C was the first to have bandswitch positions marked for all three WARC bands. Those markings were deceptive because operation on the 17 meter band caused spurious emissions. This is because
I'm not sure what board it's on but there is a circuit composed of two diodes which generate the ALC voltage. They are physically near two other diodes which generate the SWR reading. In total there
