Major Press release
 

The week of February 1 will go down in history as the week the Sony
ICF-2010 was remade into a world class portable by Mike Maghakian.
Mr. Maghakian has promised to take on the major shortcomings of the
2010, and by eliminating them, take the 2010 to a new level of
excellence never seen before.

On the drawing board are the following projects:

1) BOTH IF filters will be replaced with high quality advanced multi
element metal case ceramic filters, both having extreme shape factors
for superior performance under the worst of conditions.

2) the overweight speaker will be replaced with a much lighter one
having at at least equal audio capabilities and most likely better audio
balance. this will take significant weight off a portable that is simply
too heavy for extensive travel.

3) the battery system will go from a heavy 3 D cell to a very
lightweight high performance 4AA NiMH pack. the new battery system will
provide the voltage necessary for proper Sync functioning while
significantly reducing weight. as an extra benefit, operating cost will
go down by a large factor.

Users around the world should hold their breath as this is the first
real advancement for the 2010 since its release in the mid 80's.
Preliminary test results and research indicate this project will be a
milestone in the understanding of how a portable should be designed.

i guess it is if you have one of these 20 year old beasts!
keep us upto date on your progress, i for one know nothing about the radio
in question or any of the electronics involved but it sure sounds
interesting.

If you really want to improve that radio do something about the
chuffing problem which makes manual scanning uselessly slow.

Chuffing in the 2010? I've never noticed any chuffing at all on mine.

Perhaps I use the wrong term. On our 2010, when you manually scan
with the tuning knob at either fast or slow rate the gain goes way down
for a few milliseconds and then comes back up with a loud enough plop to
obscure any signal on the new frequency for another few milliseconds.
This means that unless you scan very slowly to allow sufficient recovery
time you can't hear anything. The 2010 is a great RCVR when you key
stroke the frequency, but doesn't manually scan worth crap. Is this
just *our* 2010 or is the problem generic ??

Nope, that's a good explanation of what "chuffing" is. But I don't have
that problem with mine, I can tune straight through a frequency range using
the knob and don't have any problem hearing signals. I will admit that it's
slightly noticable when tuning across strong signals, but it's not bad
enough to be a problem.

Anyone else have a problem with chuffing on the 2010?

Compared to some other portables I've used, the chuffing on the '2010'
is really not an issue. I used to do a lot of bandscanning with the
tuning knob on my '2010' and seldom found the chuffing to be annoying.
However I have heard that some examples of the '2010' do chuff more than
others. I'm not sure if this is related to the production date. Mine was
made in 1991.

I think I bought mine in 1992 so they're probably close enough to be
considered the same batch. Perhaps older or newer ones have worse problems.
At any rate, I mainly listen in USB so never have a problem with chuffing.

On the other hand, a few years back I watched as a friend tuned on his
DX-390, and he had to tune one step, stop, tune another step, stop, and so
on. The muting was so bad that if you kept turning the dial trying to
listen, you just wouldn't hear anything.
