They just opened up an 800 number for product info, order taking, etc for
The R8.  When I called just now, it was an answering machine telling you
that no reps were available, but you can:
        -- leave your name & address for product info
        -- order the R8.  Cost is $979 plus $10 shipping.  Ohio residents
           have sales tax additional.  They take Amex, MC & Visa.
        -- Leave your phone number for a sales rep to call you back.

The 800 number is: 1-800-9DRAKE4 .
Their regular number is: 1-513-866-2421.

I called their regular number to talk to the product manager.  He was
out to lunch & will call me back.  If all goes well, I may order one
sometime today.  If so, expect a review a week or two after receipt,
but don't expect Larry Mangne: I only have a Sangean ATS-803A to compare
it to.

 For those of you who haven't been able to see the R8 brochure yet, here
 are some highlights:

 100KHz to 30MHz coverage with optional VHF converter for 35-55 and
 108-174MHz.  Multi mode AM,FM,RTTY,CW,USB and LSB.  Five built-in
 filter bandwidths: 6,4,2.3,1.8 and 0.5KHz; 12KHz (FM only).  Synchronous
 detector.  Non-volatile memory.  Multi-voltage power supply.  RS-232
 serial interface.  Multiple scan functions.  100 memory channels.  Two
 operating VFO's.  Built-in preamp and attenuator.  Timer function.
 Dual time zone clock.  Dual mode noise blanker.  Passband offset.
 Built in speaker.  Dual antenna inputs.  Selectable AGC (with off).
 Notch filter.

 The first IF is at 45MHz and the second IF is at 50KHz.  Main selectivity
 is provided by LC filters in the 50KHz IF.  The 6/60 shape factor is
shown as 2:1 (roughly), except for the 500Hz filter which is 1.5KHz at
 -60dB.  Stability is 10ppm from -10 to 50C.  Size: 13 1/8"W x 13"D x 
 5 1/4"H.  13 pounds.  Hope this helps. The factory direct order line is
 1-800-9DRAKE4.   -Ken

I am seeing more reports that the Drake R8 is out, and promises of reviews,
which I suspect we are all looking forward to...

Has anyone had their hands on an NRD-535?
... seen any reports on one?

it would be most interesting to compare them, feature and spec and ease of

I heard it was going to be introduced last weekend.
Did anyone see it?  Know more about it?
Have one?

I am excited about an American company jumping into
the shortwave arena (or BACK in as the case may be :) )!

I heard it was going to cost $899.95.
It was supposed to have standard all the options of the competitors
(Kenwood R5000, etc).

I just called the Drake 800 number for the sales literature on the

could you post some initial impressions of the receiver.  I'm dying
to know how this one stacks up against the current 'top-end' SW

I just called the Drake 'hotline' and got the long answering
machine message.  Apparently the thing costs $975? (thereabouts).

You can order direct from them.

What I'd like to know is what do you get for the money and
do you know of anyone that sells them for discount (like a
lot of the other brands have. Kenwood r5000 ~$850).

Haven't seen one working yet, but looking at the literature it seems
like a nice radio.  Cosmetically it looks like one of Drake's satellite
TV receivers.  The thing I'm curious about is why did Drake elect to use
LC filtering rather than crystal filters?  True this allows them to give
you more bandwith selection at a lower cost, but it leaves some room for
improvement.

No-one has seen it because the first unit won't ship out till next
week (the w/o 5/13).  They are waiting on final FCC approval of
the VHF option.  

Tho, I suspect that some reviewers (like Larry Magne), have  their
hands on "early" units.  That means awhile before it hits the stands.

I will be getting one of the first units.  Add 1 week for UPS.  I will
be reviewing it... but my recent experience is limited to the Sangean
ATS-803A.  If anyone is in the LA area with a better unit, we can
move equipment around for direct comparison.

You may want to take the specs I very recently posted and compare.

FYI, Drake hasn't decided yet whether they're going to be selling the R8
through dealers yet.  Current plans are for direct sales only, however
more than one dealer is trying to negotiate for distributed sales.  What
is Drake thinking?  It's pretty hard to sell many radios when there's
nowhere for customers to get a hands-on look at the equipment.

The second IF is at 85 khz. Crystal filters for 85 khz aren't really that
practical, or that cheap to build. Drake has traditionally used such a
low second IF in order to implement their continously variable passband
system which is done with mechanically coupled LC resonators. The additional
complexity of the mechanical linkages isn't cheap either, but it does have
great operational flexibility. As is typical in modern HF rigs, the first
IF is at 45 Mhz and is intentionally rather broad, about 15 khz, but does
use a monolithic filter with fairly steep skirts.

I have touched an R8 at Dayton. The howling mob prevented me from playing
with it as much as I would have liked. I'm not really thrilled at it's
spartan satellite receiver like appearance. Whether this relative lack
of knobs to twiddle is a hinderance to normal use or not is hard to say
at this point. A series of "soft" keys under the display control a
multitude of functions. The functions change with the mode that you are
in. This allows a very few controls to control a lot of functions.
You're not likely to get lost on the panel looking for the right control,
but you might get lost in the menus looking for the right selection.
I believe a sightless operator would find this radio unusable.
On the other hand, the computer interface and the software that they
were demonstrating was very nice.
