I would like to have a go at building a receiver for listening to CW with my kids. I don't want anything on the computer, just something I can solder that will work. Is there a kit that has a good success rate? I'm in the UK if that matters.
- resters 8y agoI suggest a simple direct conversion receiver such as the really simple one in the classic book EMRFD: https://www.amazon.com/Experimental-Methods-Design-ARRL-Inc/dp/087259923X https://www.amazon.com/Experimental-Methods-Design-ARRL-Inc/...
- nickysielicki 8y agoCheck out the Pixie kits, they're extraordinarily cheap, like $5 on ebay cheap. https://www.youtube.com/watch?v=TwtErr2E1kQ https://www.youtube.com/watch?v=TwtErr2E1kQ
- taborj 8y agoI'd recommend getting a couple different crystals, at least one at 7.030Mhz, which is likely going to be more popular than the typical 7.023Mhz they come with.
- Johnythree 8y agoNot a pixie. They are super simple, but require considerable skill to use. For example, they are morse code only.
- nickysielicki 8y agoHe specifically asked for a CW device.
- p0d 8y agoYou just need a long piece of wire, diode, ferrite coil wth wire wrapped around, variable resistor and old style ear piece to pick up am radio. No batteries required. I can remember my son’s lack of interest while we made the venerable crystal radio and then his little fascinated face when we picked up some signals
- Johnythree 8y agoNo, not a variable resistor, but variable capacitor. Do a google search on "Crystal Set", or go to http://theradioboard.com/rb/index.php http://theradioboard.com/rb/index.php
