[App_rpt-users] Fw: Chinese Radios For Nodes

[Jim W7RY]

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.

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???

  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.
