B&W 5100, SX-101 combo
The combination is very good. The B&W has excellent audio and is very well
built and mannered. The SX-101 is a wonderful receiver and is a joy to QSY
with. I used one for years on 10 meters and it was so much more convenient
to tune the band than the S-line. The later SX-101A has a product detector,
but eliminates 160 meters. With a home built quad on 10-15-20 meters, I
worked over 150 countries on 10 meters in just a couple of years. Of course
the high bands were a bit better then.
I just started restoring an SX-101A to put back on the air. It is in good
shape, but someone painted the cabinet a puke silver-green. That has to go
soon.
I remember when we took this stuff out on Field Day and cranked up the
surplus 5 kw generator that had its own trailer.
The only thing bad about the SX-101 I had is that when the heater came on,
while on 10 meter cw, the frequency would gradually change. At first I
thought it was the oscillator plate voltage regulation. But, in fact, it
was the filament voltage dropping. The good news, however, was that the
oscillator tube was a 12BY7 and had its own transformer (which was left on
all the time). I built a voltage regulator and that sucker stayed put when
my heater came on.
A couple friends had the B&W and they both sounded very good. One of them
had mounted the T/R relay on the back of the B&W and when they first came on
the air, you could hear the "klunk". Seems almost like yesterday. I think
they were having a gas war during the summer and it was 19 cents a gallon.
Gee, I am almost getting teary eyed.
Calibration is not that good, but otherwise it is a fine receiver.
