Its always difficult to understand what drives a particular tech writer/draftsperson in deciding what to include and what to not include in a manual. I suspect that a true service manual, if it exist
Your simulation gave the same answer as I had posted in my previous note, which is good because that helps solidify teach analysis. When two different analyses give the same result, thats pretty good
Does anyone know if Ten Tec ever switched to FETs in the driver and predriver stages of the Scout? I am repairing one and it came to me with RF510 FETs in it instead of the 2SC2166 called out in my s
Thanks! I now find that, no matter how long I work on stuff like this, I never stop learning new things! I guess thats part of the reason I do it. This Scout came to me with no transmit. It did recei
My ex-wifes kitchen comment was always, If you can still tell what it is, its not done yet!. I installed a smoke detector in the kitchen - I used it as a dinner bell. She did, however, create in me a
I have replaced the LED illuminators in maybe 3 Orions with excellent results. I obtained my illuminators and driver boards from LCD Parts. The Orion is an easy one to repair. U have done the same LE
The band noise sounds a LOT different through a 1.8 KHz filter then through a 2.4 KHz filter, which you can quantify as Barry pointed out. However, an even easier test is to just listen to the noise
The 560 pF capacitor you removed was the capacitor that enables the oscillator in the 50398 to scan at a frequency around 4 KHz, which you could easily hear. Removing that cap would get rid of your n
OK Lyman, I knew that would fix the digit problem.. Do you have a small bench power supply? If so. try disconnecting the power to the counter module and power it from the external power supply. That
For all of you out there in Omni VI land, who archive this sort of thing, I have been working on an Omni VI that stopped mid-boot. I tried a number of things, none of which worked. Then I had a rando
The volume control in this radio is simply a variable resistor between pins 6 and 7 of U 10, the audio amplifier. If you were to place a 0.1 uF capacitor directly across these two pins, you would put
I have a known-good, guaranteed, Orion 2 display. This is, of course, the color display. $150 plus shipping. Also I have both top and bottom covers, both with excellent paint and only very few tiny n
