Re: What’s CPK-4? FORget that , look at Taurus Rx design.
Taurus was made by Wim sp5ddj/hf5wim? - creator of famous LIDIA receiver. More info (in polish)
I made 3 of them, one multiband RX with si5351 and AGD with MC3340. Nice radio.

My shipment was unusually long, taking about five weeks. But the parts are good and my project turned out well.

Thanks. Shipped and the tracking number is

year, Japan QEX will publish a long long article
about ADX-S too, if I may disclose here.

The advantage of the CRK-3 kit is that it is inexpensive. The SPAN resistor offers an inexpensive way to change bands.? Looking at the table of frequency SPAN Chart, I decided to order some resistors and a 10 position switch.? My overall cost was around $15 additional dollars.? I may even add some LED's to identify the band. Attached is a picture of the assembled switch.??

No. The step is not related with the selectivity. You don't have
to worry about the selectivity. It is processed by the internal
Digital Signal Processor. Its performance is way better than the
traditional receivers.
Thanks,

That's tuning step. It's hard to understand why there
is step as the tuning input is analog. Actually the MCU

I received my CPK3 in

sure why it took so long; maybe
because of holidays around the end of
the year. All the parts were there and
I assembled it. It worked the first
time and for the few parts it’s pretty
amazing. I found a snack, plastic box
at Family Dollar store. The box cost
less than one dollar and was easy to
use to mount the radio since it is
plastic and easy to drill. The
pictures below do not show the SMA
connector and the extended antenna.? I
have been experimenting with using
different resistors for my favorite
band. I am especially interested in
the short wave bands. The AM and FM
broadcast bands work very well. I use
a battery operated amplifier for
listening in the speaker connection.

Larry,
Thanks for the comments. Following Peter VK3YE's way to make a
3.5MHz ceramic oscillator might be a simple solution. I can supply
the ceramic oscillator if you guys need it.

I just wanted to mention how happy I am with this kit.? It works
very well and was easy to assemble.? I marvel at the simplicity of
the circuit.? Using a variable resistance instead of fixed
resistors makes for a very inexpensive kit.?
I plan to add a 10-pole switch with resistors for my next build.?
US cost should be about $16 for the switch assembly.? I ordered
resistors from Digi-Key and should get them in a few days.? The
switch was ordered from Amazon.
The sound quality is amazing.? Now, I just need to figure out an
inexpensive BFO for the shortwave bands.? Still looking for a good
case solution.? Thank you for the suggestions on this group.
