Review of CR Kits CPK-3 MW SW FM receiver kit

[@johnwest7993]

I ordered some of the chips, and I have adaptor bds for them, and a pretty good stock of passives and pots. So I'll build a couple of these with switchable preselectors and put them in boxes with audio amp chips and speakers. Make them entire custom receivers. It should be fun. I'll do it because the basic chip seems to be quite a good receiver with good audio quality. It just needs the aux circuits. Thanks for the video Peter.

Thank you! Looks like great fun on a cold winter day. I ordered two kits cpk2 & cpk3. Now I just need to fit an SMA connector to my M&P flex 13 lead in cable.

Good job on taking on SMDs. Folks find them to be intimidating, but, with a few techniques, they are no big deal. I suggest that you search YT for SMD soldering tutorials. That's how I learned. You need some techniques, like the "slide" and some soldering iron tips, like the "hoof." You will be a pro, in no time. The secret is to develop your own techniques to secure them, temporarily, to make the first solder joint... blue painter's tape, Kapton tape and Blue Tack putty are your friend. Another tip... I bought a microscope for checking my SMD work. Unless you are doing professional manufacturing, a jeweler's loop would probably work better and is much cheaper.

I think Peter needs an iron with a smaller bit for SMD work. I thought it was near impossible, but using +6.00 reading glasses from eBay, cocktail sticks for positioning components and 0.1 inch matrix board and an iron with a small bit and thin guage tin/lead solder, it is doable. Like you say, watching a few YT videos and working within a shallow lid of a cardboard box which helps to catch a component which pings off the board while being placed.

Well done. Good job with the IC. I don't think I could build this without an IC socket.

[@Kw1161]

Thanks for the video and information. Have a wonderful 2024!

[@driverfilmsshortwavechannel]

I do like these little soldering kits. Seems to perform well for the price

[@caulktel]

Great video Peter, my kit just showed up in the post yesterday so I will be building it soon.

[@chuckmaddison2924]

I do like that. I have done some surface mounting before, but the tremor in my hand is a problem now.

[@vk3ye]

However you may now be able to get a version of the kit with the SMD IC pre-soldered. Mentioned on the CR Kits website.

[@Steve-GM0HUU]

👍Thanks for video Peter.

[@youtubeaccount931]

can't go wrong with the price, looks fun

[@biancoivan65]

In the meantime, thanks for sharing your experience, I bought a couple of these ICs on Aliexpress. Do you think it is possible to add a frequency meter to see where we are positioned, and an antenna preamplifier-preselector? Greetings from Italy 🙂

[@vk3ye]

Antenna preamp / preselector is easy. Not sure about the freq meter.

[@pu3hag]

Great video! I guess you can also use this kit at a fixed frequency and turn it into the IF, detector and audio amp of frontend designed for HF and VHF Air.

[@derrick_builds]

Is there any way to deinterlace your footage before rendering out the edition you send to KZbin? Keep making great videos. You work hard man.

[@samyd5575]

What is the frequency coverage on all band?

[@vk3ye]

It has a large number of bands. Some narrow, some wide. These are listed in the instructions and on the IC's data sheet with link in video description.

[@snarfusmaximus]

C'mon man, of course you're gonna succeed with the surface mount chip. 🙂

[@kq6up]

Maybe a low value coupling cap for the antenna. Also, do you have a schematic for your BFO circuit?

[@vk3ye]

The BFO is a one transistor oscillator with a ceramic resonator. See my website vk3ye.com

[@DonzLockz]

I actually dounds great! Good job on the IC but you buggered up the DC in. Lol

[@williamwright7003]

How do I order this kit

[@williamwright7003]

OK I managed to order

[@M7XCB]

Great little kit it a shame very expensive postage to UK.

[@ronbrink5210]

Good video. Nice ic. 73 de PA2RF

[@kd5inm]

I wonder if you could turn the voltage up/down from the battery and make the RX less sensitive/ more sensitive.

[@vk3ye]

I doubt it. Sensitivity already pretty good.

[@InvestigationsDepartment]

Oh uh now i want wuna themthere things

[@bussi7859]

Kit is not for sale

[@vk3ye]

I understand the store has closed for new year and will reopen January 6.

[@minahasa999]

More videos, add filters please

[@vk3hau]

Will be no good for my location, I have the ABC 828 Mhz transmitter site 800 meters away [ Longford 3GI ] 10 KiloWatts

[@harrystevens3885]

Isn't this just the guts of one of those terrible cheap nasty Chinese radios .
