[App_rpt-users] DMK URI COS Level / Kenwood TKR-850

[David McGough]

Hi John,

Yes, the TKR-850 (version 2, at least) will interface perfectly with a DMK 
URI, no extra parts required...I've got several 750's and 850's on-line.

One caveat to note is that you may wish to add a pull-down resistor on the 
COS signal line to keep the URI from thinking the RX is active it the URI 
is unplugged from the repeater or the repeater is off.
