No need to re-thing this Kirk. It would work fine for a simple node. Now if you wanted to monitor the Win System with 100% duty cycle, you may have a point. But that is not the intent of my posting. 73 Jim W7RY From: Kirk Just Kirk Sent: Monday, February 11, 2013 9:35 PM To: Jim W7RY Subject: Re: [App_rpt-users] Chinese Radios For Nodes i dont mean to be disrespectful...but WHY would you use a POOR PERFORMING UV-5R when for less than $50 you could use a Maxtrac or Radius mobile????? RCVR performance is dismal at best with poor image rejection,lousy dynamic range and the selectivity of a barn door? The first time it stays keyed for 10 minutes you will be the proud owner of a colorful chinese blob of smoldering plastic.... Seriously...rethink this???

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 _______________________________________________ App_rpt-users mailing list App_rpt-users@ohnosec.org http://ohnosec.org/cgi-bin/mailman/listinfo/app_rpt-users
