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

make, reciever of 27 mhz cb freq. ?

i must find some cheep reciever for channel 12, and that reciever will be
connected to cwdecoder on pc... (pc will watch cw on that channel... for
using in case of emergency)

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

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.

well i would preffer amplitude modulated tone....

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..
