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.

Re: shipping

 

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

CPK-3 mod

 

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.

That's tuning step. It's hard to understand why there is step as the tuning input is analog. Actually the MCU inside the chip treat all the analog input as digital.

I received my CPK3 in the mail after five weeks. I am not 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.

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.
