I have a Micro 555 dual conversion FM reciever that, when the circuit board is in the case, has no more than 5-6 feet range with xmtr antenna down. If removed from the case Recvr seems to work intermittantly with great range.

If I extend the Xmtr antenna, reception is fine, in or out of the case.

Suggestions at to the cause of this problem would be greatly appreciated

Thanks,

Danny M

Doesn't seem to me that you have a problem. AM & FM radios need the antenna out for proper operation.

If you don't want to have the transmitter antenna way out then get a 2.4GHz system like a Spektrum.
