For the average user a standard FOB, whether it be DMK or modified Chinese, works just fine. I don't want people to get the idea this is going to do something special for them and they need to spend the extra money and buy it. Most all radios have TX timeouts so that point is taken care of. The other issues don't apply to most radios. I don't understand the cos/ctcss one because like PTT this is SW switchable.<br id="FontBreak"></font><br><font style="" face="Tahoma,sans-serif">Most hams are cheap and building, modifying etc. are a large part of our hobby. We usually don't put dollars and cents on our time. It's the fun of doing it. Anyone can buy something and throw it on the air. Everyone has to make the decision what's best for them. <br><br>The FOB mod I described in the how-to on the web page is really a piece of cake. All you need to do is solder some wires on the FOB and build a minimal amount of external circuitry. I made it harder (mechanically) because I put it in a nice box which is not necessary. For $10 or less worth of parts and a few hours of your time you have an interface.<br></font><br><b><font style="font-size:16pt;" size="4">73 Doug</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">WA3DSP</font><font style="font-size:16pt;" size="4"><br></font><font style="font-size:16pt;" size="4">http://www.crompton.com/hamradio</font></b><font style="font-size:16pt;" size="4"><br></font><br><br><div><hr id="stopSpelling">Date: Sat, 15 Nov 2014 22:40:18 -0500<br>From: kuggie@kuggie.com<br>To: arm-allstar@hamvoip.org<br>Subject: Re: [arm-allstar] Yet another USB FOB Modification<br><br>

The effort to make a $2.50 FOB work is well worth it at that
cost. The DMK URI is only $70.</font><br>

When?<br>
<br>
1, When you need 8 to 10 Volts of audio like driving a FM modulator
directly (GE M2).<br>
2, When you want the ability to revert to in-cabinet controls when
the BBB blows up.<br>
3, When you need the additional AF filtering because you are driving
the modulator directly.<br>
4, When you have the wrong polarity COS or CTCSS hardware logic and
don't want to hack in a bunch of circuitry to correct for it.<br>
5, When you absolutely don't want the transmitter keyed for days on
end because Asterisk hung and the FOB is stuck in transmit.<br>
<br>
That's when...<br>
