One has nothing to do with the other. Use the CM108/119 FOB for the audio, and COS from the radio to the GPIO COS in. I wouldn't use speaker audio, BTW. GeorgeC W2DB/2360 On 5/27/2016 9:07 PM, Skyler F wrote:

This is what I am trying to say: There are several cases when I don't want to use DSP and use COR. (Weather we are using flat or speaker is not relevant) On the raspberry pi, it is easy to use the wiring pi program and a modification of K0KN's astled script for PTT. However, I have no idea how I would wright a script to tell Allstar that there is a COR detection when the GPIO input on the pi has gone high. If anybody knows more about it, could they help with a script? The bash command "gpio read <PIN number> " will return a value 1 or 0. How do I pipe this to Allstar COR?

Ah. Can't help you there but others here have done that. I have only used paralell port pins for COS and PTT on standard micro PC cards (D945, etc) just starting on the pi trail now. GC On 5/28/2016 10:32 AM, Skyler F wrote:

Here's another approach for you folks that like to build stuff, but the wiring to the CM108/119 is intimidating or you are running into problems finding leaded USB adapters. The RA-35 is a $35 radio adapter with many benefits over a simple FOB. Whether or not it suits your application or budget is up to you. Here are the high points: Complete kit - you solder everything - $35.00 Complete kit with the CM119A and EEPROM pre-soldered - $45.00 Verbose information available here: http://www.masterscommunications.com/ Click on RA-35.

Hear, hear. no dog in this hunt, but I've not found an interface which was as flexible and easy to use, and i have a shack full of dmk uri dongles. everything from a boafeng 888 through alinco dr transcievers in simplex and as a repreater, a repeaterbuilder micor conversion, gm300s, an msf5000, hooked to both acid and dial on pi computers, and with a speaker on one of the outputs to boot. 45 bucks with the chips presoldered, it has the right chip, not some potted knock-off, a memory chip, iirc, kevin brought out a few gpio pins, spend a few couple hours stuffing a board, and you are supporting a fellow ham. is 45 bucks REALLY going to break the bank for something that, if you can read a schematic and understand a parts list??? no financial interest other than a satisfied customer. -- Bryan Sent from my iPhone 6S...No electrons were harmed in the sending of this message.

Hi Bob, VOX can be done to generate the RX COS signal, but, it isn't ideal at all--I've tried it. The list of reasons is long, below is a quick from my experience. The circuit in QST is designed to provide PTT from a computer-generated digital signal, and it should work well for that. Remember that when the radio should be transmitting, MODEM audio from the computer is continuous and roughly constant in peak level. Once the computer MODEM transmission is complete, the output level drops to virtually zero, with very little audio noise of any kind from the computer. This scenario is ideal for VOX--a single, predictable keying threshold set-point and a very short no-signal cut off delay. Audio from an FM receiver is different. It has many complications for trying to use VOX to generate COS. First, you'll need a more complex circuit that implements both an adjustable unkey delay (remember: human voice isn't constant) and input level set-point, which may be complicated to adjust due to various noises coming from the RX. So, at best, you'll likely end up with a customized solution that works only with a signal FM radio without tweaking all the settings again and again. Then, another issue is that you may loose the first syllable of audio at key-up, while the VOX activates. As I said, VOX can be done for casual use. But, with the effort involved to get VOX to work, just put that same effort into making a real COS circuit! 73, David KB4FXC On Sat, 28 May 2016 k5mvz@verizon.net wrote:
