Newbie level 4
2m receiver
Hello everyone
I am Ramesh and am planning to take part in a Radio Detection Event (A foxhunt).
For the event I have to build my own receiver(readymade not allowed but can use ICs)
Morse code will be transmitted b/w 144-146 Mhz FM.
Plz help me out:
1) I have never really built anything so complex so I was thinking of modifying an existing FM(88-108 Mhz , schematics are relatively easy to find on the net) circuit to work at 144-146 Mhz.
I figure that I'd need to change a couple of capacitors and I'd be done.Plz tell me if this is true..and if yes , how should I go about it? Can any1 plz suggest a schematic and what modifications shld be done to it?
2)I have searched a lot for 144 Mhz FM receiver but haven't found any good schematics...Plz could some1 tell me ?
3)Has any1 taken part in these competition?Can you tell me your experience?And any other info a first-timer like me would need to know??
Thanks!!!
