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.

I'm starting to feel better; I wasn't familar with the B&W
transmitter, and wanting to be able to sleep at night, I
probably offered more than most would have under the
same circumstances.
