I have a very good condition used Clifton Laboratories Z90 panadapter,
with the complete set of "running spares" available for sale. This Z90
was owned by a customer who is, for medical reasons, no longer able to
enjoy ham radio and has asked me to see if it can be put to good use.
For those not familiar with the Z90, it's the first product of Clifton
Laboratories and is a microprocessor controlled digital panadapter. I
believe it was the first digital panadapter kit aimed at the ham radio
market. It was the cover story in the March/April 2007 QEX, with part
two published in the May/June 2007 QEX. You can learn more than you
ever wanted to know about the Z90 at
http://www.cliftonlaboratories.com/Z90.htm and if that's not enough
detail, additional links can be found at
http://www.cliftonlaboratories.com/prior_products_-_no_longer_available.htm
The Z90 was produced in one run only, 50 units split between the Z90
with LCD display and the Z91 computer interface model.
The Z90 was designed with K2 owners in mind, but it's a general purpose
digital panadapter suitable for IF frequencies from 455 KHz to above 60
MHz, although performance drops off above 60 MHz. It works with the K3,
but the Z90 does not have the integration bells and whistles for tuning,
etc. that later panadapters have.
In 2007, a new assembled Z90 with running spares sold for about $700.
With the consent of the original owner (and thanks to the permission of
Eric and Wayne to post this information on the Elecraft reflector) the
proceeds from the sale will go to a local charity, the Lee Fendall House
in Alexandria VA. www.leefendallhouse.org
Here's the fine print ...
1) The purchaser will make payment directly to the Lee Fendall House and
when the payment is received, I'll ship the Z90 and accessories to the
purchaser.
2) Although the Lee Fendall House is a non-profit charity, my
understanding of the tax code is that donations are deductible for tax
purposes only to the extent they exceed the fair market value of
"premiums" received. In this case, I believe the fair market value of
the Z90 will be whatever the sale brings, so the purchase price will not
be deductible as a charitable contribution. You may wish to consult with
your tax adviser, of course.
3) I will include - no extra charge - a Z10000B buffer amplifier (either
kit or assembled) if the purchaser needs that to connect the Z90 to a
particular receiver. If the purchaser will use it with a K2, I'll
include the Z10000B-K2 version of the buffer amplifier. If the Z90 is
to be used with a K2, I will also provide a bandpass filter designed to
go between the Z10000 buffer amplifier output and the Z90 input.
4) In order to maximize the amount the Lee Fendall House will receive,
the sale will be to the person offering the highest bid. I'll keep
bidding open for 1 week and the successful bidder will be determined on
bids received as of 3 PM east coast time April 9th.
5) No charge for shipping by Priority Mail within the US, but for non-US
purchasers an extra charge for shipping will be applied.
6) Please send your bids and any questions you may have to Jack Smith
K8ZOA at [email protected]
7) The sale includes:
a. Z90 panadapter
b. 12V DC "wall wart" power supply
c. Detailed construction, maintenance and operating manual (the manual
is nearly 1" thick and contains fold-out 11x17 schematics complete with
voltage, resistance and oscilloscope captures for maintenance support.
d. Running spares kit
e. If the purchaser needs it, a Z10000B buffer amplifier kit or
assembled PCB and cable set
f. If the purchaser will use it with a K2, the -K2 version buffer
amplifier will be supplied along with the special K2 bandpass filter
