I have sent my
R-390 to China!!! I traded it
for a Chinese (Army) Type 77 HF Receiver. Note I mean my
R-390-non-A... NOT
my Chuck Rippel-rebuilt R-390-A. What an interesting adventure this has
been.
I had seen emails soliciting
R-390s for a
couple of years... and finally decided to take the plunge with my
R-390. It
was only possible because the R-390 is a modular-plug-in receiver. If you
take enough of 'em out, you can just get it through the weight restriction
of 44 lbs / 20 kg. There is a girth restriction of 72 inches. That means
that the height, plus the width plus the depth of the box must not exceed 72
inches (~183 cm). That leaves ~ an inch (2.5cm) all around the R-390. Not
very much!!! ...and oh yes: Chinese regulations state
NO WOOD.
But the packing store guy is a friend,
and though he groaned a lot, he really came through for me! He first
built a double-walled cardboard box around the unit. Then he built
double-thick top and bottom pieces that left about 5 inches (~13 cm). Taping
the top and bottom pieces made for a very secure package-or rather, a
package as secure as it could be
with these restraints. It was easy to pick up-considering its weight.
So now, on to the post office. I had several
packages, and had to make more than one trip from the car. Hoisting the big
box onto the postal counter, and telling them it was for the
Peoples' Republic of China
got some *** very *** raised
eyebrows!!! I had been told there were two important points about the Customs
form: 1) the total value had to be no more than
90 yuan (~$85); and, 2) the description of the
item(s) my friend suggested was: "old radio for collector".
I followed this... but added: "(1955)". I
didn't want some potential thief anywhere throughout the passage to think it
might have been an Atwater-Kent!!!
I hadn't-yet-discussed my choices. I could
have-in exchange for the R-390-either a "NOS (New-Old-Stock)/ NIB
(New-In-Box) w/ spares" Type 222 tube receiver;
or a similarly NOS/NIB Type 77 solid-state
receiver. My friend has both for trades. I gave this a lot of thought. I had photos
of both receivers (see below). I was leaning towards the
Type 77. If there were any tubes in the
Type 222 that didn't have European/American
pin-for-pin equivalents, and something failed, once the "spares" were gone,
you were just plain out-of-luck. On the other hand, you can manage to
replace *** any ***
transistor. The final decision was made by my friend in China. I asked him which he thought
was the better receiver, and he said that-although it was
uglier-the
Type 77 was much better. Well... that did it
for me.
So... my R-390
was sent on its way to China. My Type 77 HF Receiver
arrived in ~ 4 weeks; and the R-390 got to my friend in ~ 6 weeks. Below are
thumbnails of both the Type 222, and the
Type 77... plus a hand drawing my friend did for me to interpret the Chinese characters on the front panel (the
numbers are standard Arabic.)
The receiver accepts either
220 VAC (but has a dual-primary transformer, so
it should easily change to 110 VAC) OR
12VDC (with -6VDC
required for AGC and something else I forget.)
The quality of design and the construction is mostly 1st rate, with only one
or two things that are probably more oddity than defect. It is very solid,
with a die-cast aluminum frame. The frequency R/O is via a very-finely-silkscreened
fan (or baseball-field) shaped partial-disc. The ingenious rapid-band-change
mechanism is very impressive.
More-to come...
First the Type 222
(that I didn't get):

Now the
Type 77:
