In addition to his current "Yellow Box" nodes which have been very successful with hundreds delivered he will be offering two FOBS and a radio-less node. All of these products have been successfully tested and are now in production. FOB delivery will start sometime in January 2019 and radio-less nodes shortly after that.</div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small"></div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small">The FOB's use the CM119B and have RF isolation on all radio and GPIO leads. One FOB is strictly for radio use with the five common signals and the other has all the GPIO like the DMK URI. Although no price has been set yet they will sell for considerably less than the DMK URI and less than most other FOB's currently out there. A photo of the Full GPIO board is attached. It is smaller than most other boards and the board without GPIO is smaller yet. <br></div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small">The Radio-less node puts everything in one box and includes an adaption of the Yaesu Microphone to overcome the problems with in mic. DTMF. It uses an Arduino to convert Yaesu Mic. output to DTMF. It also includes an analog devices mic compressor/limiter chip which is necessary when using direct mic. input to an A/D. It makes a complete plug and play package with an extremely powerful 60W rated Class D audio amplifier. Connect 12V, Ethernet, and a speaker and you have a complete node. It can also be run wireless on 2.4 or 5G. This is ideal for mobile operation or sites where RF might be undesirable such as an EOC. Again final price has not been set yet and it will not be available until later in January. A preliminary photo is attached. The final version will be in the same case but slightly different layout.</div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small">Also shown is the "Yellow Box" node with the new FOB board and new layout.<br></div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small"><br></div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small">Final photos, prices and specs will be available soon.<br></div><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small"><div dir="ltr"><div class="gmail_default" style="font-family:tahoma,sans-serif;font-size:small"><br clear="all"></div><div><div class="m_-5955725116292213923m_-1525941554602849038m_-8738538395014733859gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div><b><font size="4">73 Doug<br></font></b></div><b><font size="4">WA3DSP<br></font></b></div><b><font size="4"><a href="http://www.crompton.com/hamradio" target="_blank">http://www.crompton.com/hamradio</a><br></font></b></div></div></div>

What is the current state of being able to key PTT from GPIO?<br>
<br>
I already have a USB Microphone I could bring into the Pi. (A Blue Snowball)<br>
and already have a 12v 10watt external stereo amp for driving speakers (it’s in the parts bin) from the stereo output.<br>
<br>
<br>
<br>
Recommendations?<br>
<br>
Options I know of are DMK Engineering’s URI and RA-42, but these add a lot to the cost of the unit.<br>
