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. I use a battery operated amplifier for listening in the speaker connection. ?73’s N9EGT Wayne?

Adam, would you tell us what the third column for CPK-3 means in the chart?? Usually it reads 50 Khz, 100, 1, 5, 9 etc???

Thanks.

Wayne

Thanks for sharing the case idea, Wayne. It took too long to ship during the holiday season perhaps because people have ordered too many gifts directly from China. I hope it will be better soon.

Thanks,

Adam

I thought that it was like that. So the less number means more selectivity? ?

Thanks.?

Wayne,

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.

Thanks,
