Users of MII mobiles as repeaters and/or base stations: You should expect interference when you cut corners to save a buck and use a mobile for a repeater. The mobile has no shielding to prevent RF entry or exit, none of the leads are in/out of the Rx and Tx are bypassed as in the MII stations! Mobile sets were never designed for this purpose. If you put a mobile on the air as a station and do not receive or give interference to others, consider yourself lucky.

You don't hear it when the radio is TXing because the T/R relay disconnects the receiver from the antenna. --- Jeff -- No virus found in this outgoing message. Checked by AVG Free Edition.
