Buy one and find out. I have no idea. 73 Jim W7RY From: Corey Dean Sent: Tuesday, February 12, 2013 5:01 AM To: Jim W7RY ; app_rpt-users@ohnosec.org Subject: RE: [App_rpt-users] Chinese Radios For Nodes But the question is, will the radio hold up to the key up times? Corey N3FE From: app_rpt-users-bounces@ohnosec.org [mailto:app_rpt-users-bounces@ohnosec.org] On Behalf Of Jim W7RY Sent: Tuesday, February 12, 2013 12:29 AM To: app_rpt-users@ohnosec.org Subject: [App_rpt-users] Chinese Radios For Nodes I found this schematic on line for a UV5R. http://files.radioscanner.ru/files/download/file14137/shema-baofeng-5r.pdf There is COR voltage along with some transistors that control the TDA-2822 audio chip. There is also a discrete volume control too. So you can get fixed de-emphasised RX audio to drive a URI. So it looks like the UV5r would be a good candidate for a node radio and long as you use the internal PL decoder which would be fine. 73 Jim W7RY -- This message was scanned and is believed to be clean.
