[App_rpt-users] DMK URI and Baofeng Radios

[Bob]

You may find http://alaskareflector.org/zl1nc/UV-COS.html to be helpful in
achieving a COS from the Baeofeng. The UV-5R circuit diagram is available at
http://www.miklor.com/uv5r/. I'm working on combining the COS at the mic
jack pin 4 for the same purpose, which will require some modification to be
compatible with the bias on pin 3 of the 3.5 mm jack. PTT can be asserted on
pin 5 are a shorting relay between this pin and pin 5 of the speaker 2.5 mm
jack. Tx pin 1 and Rx on the 2.5mm speaker output.

Subject: [App_rpt-users] DMK URI and Baofeng Radios

 

Hello,

 

I am looking to set up my first Allstar node and I'm going to use either a
Baofeng UV-5R or UV-82 HT for the radio.  I plan to interface this to the
node with a DMK Engineering URI (http://dmkeng.com/URI_Order_Page.htm) I
have yet to order.  Does anyone here have experience with interfacing
Baofeng HTs to the DMK URI and have any tips on how to secure the connection
and anything else I should know?  I am also interested in Echolink so a
product that would be compatible with Echolink would be my best choice.

 

Any other suggestions for radio interfaces would be welcome as well.  I have
looked into Advanced Repeater Systems' products as well
(http://arsrepeaters.com/USB_AllStar_Adapters.php) and they look excellent,
however, I would prefer the versatility of something like the URI for when I
upgrade the radio on the node.  It looks like the ARS product only
interfaces to a certain radio but the URI will interface to anything (give
you know the pinouts on your radio, etc).

 

So all in all, I am getting started and have yet to choose an interface.  I
have the Baofeng radio chosen as my starter radio, everything else is open
to suggestions!

 

Thanks

 

Adam
