Hello all:

Have been playing with my JRC NRD 545 for quite a while now, and really
very satisfied, and happy, with it.

But am absolutely convinced that I'm not using it to it's best
advantage, and not taking advantage of all of its capabilities.

Still consider myself pretty new at this hobby.

If anyone has a few spare minutes, would be most grateful for a small
discourse on the following:

a. regarding "NOTCH," and "NOTCH TRACKING":

When, and How, are these two functions utilized ?

b. the same for "NB-1 LEVEL, and "NB2" ?

Much thanks,
Bob

Good questions. I have the same radio and there is so much to it that if
I start playing around with my other ones I forget how to use it. I see
you are already a member of the Yahoo Group. I was going to tell you
about it.

You have an EXCELLENT radio there!

NOTCH is used to kill, or "apply an attenuation notch" to, an undesired signal
or tone in the passband. I use it all the time to kill tune-up whistles or
hetrodynes (those annoying tones or whistles) that you hear, especially on SSB.
The 545's notch is excellent. NOTCH is engaged by pushing the button once
(green light), then turning the associated knob back and forth until you find
the sweet spot that kills the offending tone. Once you've adjusted the knob,
you can engage TRACKING (AUTO NOTCH) by pushing said button one more time (red
light). TRACKING (AUTO NOTCH) will automatically track and kill the offending
tone should you decide to turn the main tuning knob.

NB1, NB2, and the associated knob is the NOISE BLANKER, which is used to reduce
some types of noise (electrical noise, spark plug noise from motors, and other
types of annoying crap). Push the button once (green light) for NB1, twice (red
light) for NB2, adjust the knob for best reception. NB1 is better on some
noises, NB2 is better on others. However, some noises can't be killed no matter
what.

All this is explained in the 545's instruction manual. If you haven't seriously
read the manual, you're missing out on a lot of the 545's features, especially
the DSP parameter adjustments.
