Our club has to repeaters a VHF & UHF as of late they have what we the club members call a monster in it, one of the things it is doing echo when both are ID'ing or in use one will echo somehow with the other like having to radios on same freq. and the other problem is the VHF wanting to keep keying it self we have stopped the re-keying for now by eliminating the delay tail on it how ever it still try to re-key are there any thoughts on this or has anyone run into this problem before.
