TELAMON,

So had Icom come out with an R75A and R75B model like
the Drake R8A and R8B then it would be a good radio ?

IMHO: It's the R75's Mods that personalize the radio
and endears the R75 to it's owners.

The Icom R75 does not have QC problems I'm aware of. It does have design
problems and is the reason people have the units modified.

I own a second hand one, for over 14 months now.
It never let me down, i think it´s a fine reciever with great performance.
Of course it´s not comparable with some $4000 + professional receivers, but
for what i´ve spend on it i´ve got a lot of fun.
I´m not into electronics, and i can´t tell the difference between a
capacitor and a resistor but i´ve modded mine with the AGC/SAM mods just for
fun.
Before the mods it was a fine receiver, comparable with my Lowe HF-225, and
now it´s even better.

hi Neil:

Kiwa offers Pete's MW mod but even without it the R75 MW SSB sensitivity is
2.0 uV [pre-amps OFF]. external noise on MW is ~10 dBuV [3.16 uV]. antenna
is critical on MW: indoors get a Quantum QX loop or build a 34" square box
loop, outdoors a K9AY (need 40' square) or beverages. get an external
speaker; the internal is small and covered with plastic to resist dust
entry.


hi Telamon:

I'm not spending hundreds of dollars on a radio that
must be modified to work as advertised.


no problem. but aren't you this electronics guru? imagine a machine shop
owner buying his car based on stock horsepower while balking at someone
bolting on a supercharger. what can you hear on your RX340 that you cannot
on your R8B? on an R75? please site specific specs. we all know the answer
and that is why the R75 is now one of the best selling tabletops.


hi Starman:

I've never heard of any failure of the transformer or
associated AC power supply components.


strawman argument? there are no failures, there are alignments.

The R75 sounds much better with an external speaker but it's
still not as good as an R8, particularly for program listening.


the modded R75 has fidelity, working SAM, and a better filter for SAM
sideband selection.

There is no sync' mod for the R75 that makes it work as
well as the sync' on an R8B.


says who? the guy who in 2002 said the R75 had "no synchronous selectable
sideband" then in 2004 said DUH "synchronous selectable sideband actually
being somewhat functional". the guy who in 2003 could not get a Kiwa modded
R75 to review but in 2004 sited "exceptionally fast turnaround"? the guy
who stated "added crispness marginally improves audio" but got the wrong
audio mod? the guy who "forgot" the "1/2" on the Kiwa modded R75's rating?

I prefer to pay more for a receiver that doesn't need many
(if any) mod's, than to pay less up front and then spend
more time and money to get it working acceptably.


spend time doing what? the work has already been done. you send Kiwa a
radio and an $80 check. who knows, maybe 2004 will be the year you fix the
R8B's synthesizer with encoder lubricant.

regards,
phil

Yes and after Pete's mod the sensitivity is .07 uv.

Yes Phil right in the dead center, nice argument.

Yes expensive friendly [$$$$$] aligments from Mr Drake an his nice
service guys.Any 101 course electronic technician knows that extreme
heat near delicated component can change its critical tolerance and
with that the need for aligments.Why do you think the drake service
dept is so famous?.

the modded R75 has fidelity, working SAM, and a better filter for SAM

With an external speaker and the Phidelity mod the sound is much
better and clear with its quiet circuitry .

work as
well as the sync' on an R8B.

Just wondering, are you insinuating that this "guy" FORGOT the 1/2
start in the R75 rating [see passport site]only by a "coincidence"?
NAHHHHHH we all are too mature to believe in silly "coincidences" like
that.Like einstein said God don't play dice.This guy was the same that
said in a Grundig advertisement "the sat 800 is the most powerfull
radio in the world" and about the R8B "it get everything right".

A lot of radio enthusiastics know how to solder and with some care
they are working in their radios having fun and saving some service
money.If you know how to solder and have a good magnifier your
sync/agc mod cost can be less than $10.00.

Extreme heat? My R8 ran warm enough that the cats liked to snuggle up to it.

Ever compare the case of an R8 series radio with a similar sized set that uses tubes?

I suspect the reason the Drake service department is famous is if you call them up with a question, they treat you like a valued customer. They sent me an owners manual for the R8 I bought used for free.

Since these mods are well known, simple and inexpensive, why hasn't the factory hasn't gotten around to incorporating them into the design?

It would eliminate almost every complaint people have about the radio.

I think the answer is not enough owners have complained.

Remember that cats have 9 lives.

But a tubes receiver components [resistors,cap,transistor]have better
heat tolerance than the R8 mini IC's,cap,resistors ect.Do you know
that a lot of capacitor in a tube set can work with more than 400v
applied? What about a tube set resistors? Do you ever see a huge 10
watts one?

Yes but send your R8 and r8B for aligment or encoder repair and pray
God before the bill arrive.For sure they are very friendly [$$$$]
people and sometimes send some owners manuals for free.Remember that
you can find a lot of receivers manuals for free [online].

Yes and with that the elimination of the $450.00 [free DSP]offer for a
radio with a list price of $1,100.
I think the answer is not enough owners have complained.

We are complaining but at the same time designing new and easy
upgrades for it and now we have a champ that can compete with any
radio in the market.

Perhaps the best way to solve the ICOM R75 problem is to contact the Federal Trade Commission and ask them why ICOM is dumping their receivers in the USA at a greatly discounted price.

What we need is a trade war with Japan! ;-)

I would not call myself a guru but being in the work force a few decades
in various capacities in electronics technology I have well rounded
experience.

I haven't noticed anything that the RX340 can pick up that the R8B can't
hear. Usually the RX340 can make a station sound better but other times
the R8B does better depending on conditions. The radios are all on
different antennas, which make for a different reception condition so I
am not generally comparing them.

I would not be buying a new car and modifying it either. An older out of
warranty car could be a different story. In my youth I was into street
racing and did just that.

Some people just don't understand that anything manufactured has
engineering compromises built in. Each radio when designed has a slew of
compromises where one performance parameter is diminished in favor of
another. The result is that depending on situation and conditions one
radio will do better than another. Change the situation or conditions
and the other radio does better so which is best?

You generally get what you pay for. Spend more money on a radio and you
can get higher quality components resulting in better specifications,
reliability, capabilities or operational features.
