Hi,<br>
<br>
Stick this in your rpt.conf...<br>
<br>
outstreamcmd=/bin/sh,-c,/usr/local/bin/lame --preset cbr 16 -r -m m -s 8<br>
--bitwidth 16 - - | /usr/local/bin/ezstream -c /etc/ezstream.xml<br>

You will need lame and ezstream obviously...<br>

Thanks guys!<br>
<br>
Buddy and Chris both helped me out and it seems to be working fine.<br>
Now to work though the learning curve...<br>

Subject: [App_rpt-users] EMI/RFI issue<br>
Message-ID: <1371355119.1896.4772.camel@benjamin-hp><br>

Greetings All,<br>
<br>
While thinking of a way I can turn my node into a portable allstar node,<br>
it has been discovered the computer I'm using, generates RFI/EMI over<br>
the DC power connection.<br>
<br>
The setup is as follows presently, which has zero *known* EMI/RFI<br>
issues. The radio is powered with an older linear 3A regulated power<br>
supply, which a parallel connection to a 12V 18Ah battery. All leads are<br>
kept short, under two feet. The radio is kept on 5W.<br>
<br>
The computer has a 12Vdc connection, and it's presently using an ac/dc<br>
SMPS, one that can be bought on eBay for about $10.<br>
<br>
Both of these are plugged into the same outlet strip, and as stated,<br>
zero discovered EMI/RFI issues.<br>
<br>
The radio audio connections to the computer have the center conductors<br>
isolated with a 10nF cap.<br>
<br>
Just as soon as I decide to power the computer from the battery, the<br>
radio has noise across every tunable frequency. Even if I disconnect the<br>
radio completely from the node, there is noise on the radio. From what<br>
is apparent to me, the noise is coming from the computers internal power<br>
supply section, riding the power wires back to the battery, and then to<br>
the radio.<br>
<br>
I see there are plenty of EMI/RFI filters I can purchase. However, I'd<br>
like to maintain the Amateur Radio Spirit of creation for this case, so<br>
I'd like some pointers on what I should test for, and construct some<br>
EMI/RFI filters.<br>
<br>
I have seen there are common mode and differential mode chokes filters,<br>
and some filters have both kinds of chokes. I'm not really sure the<br>
difference, besides the way the components are installed in the circuit.<br>
<br>
If you find it better to talk in person, contact me via allstar or look<br>
for my phone number on the internet.<br>

Perhaps a:<br>
<br>
RadioShack? Snap-Together Ferrite Choke Core (273-105)<br>
might do the trick, or maybe a:<br>
<br>
Snap Choke Core (273-069)<br>
<br>
or something similar.<br>
