I did not work for Tektronix. I worked for an independent calibration lab called "Intertyme Metrology Laboratory." I serviced a lot of Tek 547, 544, 535, and various plug-ins for them like 1A4, 1A2 a

What is considered a "normal" configuration of filters, 5 of them in the radio? The filters are "optional", so there is no "normal." The most "typical" selection of filters to put in the 6.3 MHz IF f

The LSB or USB transmit signal is produced in the balanced modulator, and then filtered to remove the unwanted sideband. The DSB signal that is eventually run through the filter, to remove the unwant

Mark, How did you set the BFO frequencies? What measuring device did you use? And what frequency reference is it based on? Some sort of counter with a built in reference oscillator? How do you know i

The Omni VI is my favorite rig for CW. I think it is worth the effort to either troubleshoot it yourself or get Ten-Tec to do it. Have you checked the BFO frequencies? If you don't have a frequency c

There are many kinds of noise blankers. They differ in the way they decide when to blank the signal (their triggering source), where in the signal path they perform the blanking, and the timing of th

Yes Noise Blankers and Noise Reduction devices are quite different. I'm not sure exactly how Noise Reduction systems work, but I'm pretty sure they not not completely blank the whole signal. Noise Bl

The ANC-4 is not a noise blanker, and it is also not a DSP noise reduction device. As it's model number suggests it is a "noise canceller." What it really does is use an additional antenna and some p

If you need a new transformer think of it as an opportunity for an improvement to the amplifier. The improvements could be higher plate voltage, and perhaps using a separate transformer for the filam

They are both commonly available and they can both be used to power typical HF transceivers. I think it is a reasonable comparison to make. Here is another question: What kind of power supply did you
