I'm contemplating a second kit run on the Z10000 IF sample buffer
amplifier, and I'm interested in whether there is any interest in a
second run.
For the unfamiliar, the Z10000 kit is a small PCB that pulls an isolated
sample of the K2's IF signal out and makes it available on an SMA
connector installed on the K2's rear panel. There's a great deal more
information on it that can be obtained by reading the manual at
http://www.cliftonlaboratories.com/Documents/Z10000%20Buffer%20Amplifier%20Assembly%20&%20Operation.pdf.
Also, http://www.cliftonlaboratories.com/k2_interface.htm provides more
details.
My thought is that with the increasing interest in using a Softrock
receiver as a K2 panadapter, there needs to be a way to extract the IF
signal and to prevent the Softrock's nasty local oscillator signal
(around -40 dBm or stronger) from getting back into the K2. That's
exactly the purpose for which the Z10000 was built.
The original Z10000 price was subsidized by the associated Z90
panadapter, which will not be the case on a second run. Hence, there
will be a price increase to $34.95. If I go ahead with the second run,
this price will include the PCB, all parts, a cable with the miniature
coaxial cable and SMA connector installed and a printed copy of the
assembly and operation manual, and postage within the US. If sufficient
interest is found, I would make the second run available beginning in
mid-to-late April.
The kit can be built either in the K2 version (which includes bandpass
shaped response) or the broadband version, suitable for receivers with a
different IF. Price is the same, but the universal and K2-specific kits
will be different products.
Please respond privately to me.
