there is one RX from 1.5 to 120 MHz you just have to work out the coils.

What kind of "CW"? Keyed carrier or modulate tone (MCW)?

well i would preffer amplitude modulated tone....

The simplest receiver you could build would be a superregenerative,
as was used in simple handhelds sold in the early 1950s. That would
work fine for MCW type signals, but would not do for keyed carrier
CW.


wheare i can found schematics of that handhelds?

if you go to this site

http://qrp.pops.net/qrp/default.htm

and look at the

http://www.qrp.pops.net/cascoder1.htm

its designed for 7 MHz but you can change that by downloading

http://www.qrp.pops.net/apps/resonator.zip

and putting in the frequency of your choice, the schematic it will give you,
should be enough to change the front end of the 7 MHz RX..
That should get you 1/2 way there..
