<div class="moz-cite-prefix">I must have to respectfully disagree
with Kirk as well. Many times, from a real repeater site,
communications can be done with very little power. A local
coverage node (inside ones house) can be done on low power as
well. The UV-5R will handle multiple 3 minute key-downs on low
power without turning into a plastic blob (remote base
operation). CTCSS hides most receiver inadequacies.<br>
<br>
Not everyone has ready access to programming hardware and software
need for a Maxtrac or Radius, so these cheap Chinese radios can be
moved in frequency without effort. Sure, they're not a Motorola,
but many times users of AllStar don't necessarily need a Motorola
quality radio.<br>
<br>
That said, one of my most favorite radios for dedicated linking is
a MaraTrac. The VHF 100 Watt model usually is very cheap and it's
easy to convert them to a lower powered unit by snipping out
several components and using solder wick to 'bypass' the 2 final
transistors. You end up with a 15 Watt unit that will last almost
forever. <br>
<br>
Bottom line - it's all in what you want and need.<br>

<div>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.

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?????
<div>RCVR performance is dismal at best with poor
image rejection,lousy dynamic range and the
selectivity of a barn door?</div>
<div>The first time it stays keyed for 10 minutes you
will be the proud owner of a colorful chinese blob

<div>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.</div>
