see Oct 2019 QST for this circuit using a 2N2222 transistor. The optoisolator is a good option as well.

If you want to do this the easy way,  use a Signalink USB.

Just my 2 cents.

Hello Folkert,
I use the Pi and Direwolf in the scenario you mention.
I take the PTT from GPIO 24 and DCD (optional) from GPIO 25. These are configurable in direwolf.conf
Now, the PTT switch.
I use an FOD817 Optocoupler.   The GPIO PTT goes to pin 1 of the 817 and take pin 2 of the 817 to ground through a 680 Ohm resistor to limit current in the diode.
Ground pin 3 of the 817. Pin 4 should go to the 5V source on the GPIO through a 10k resistor (either pins 2 or 4.)  Take the PTT to the radio also from pin 4.
I've tested this on Yaesu mobile rigs, Alinco DR119 and the Baofeng 5Rs.  The pull-up 10K on pin 4 of the 817 keeps the 817 from floating when the biasing diode floats when the PTT signal isn't 3.3v.  (This is sometimes a problem with the Baofengs as they can stick in transmit even though the GPIO 3.3 has gone low.  
Attached is a sketch of my circuit that works.  I'm sure the circuit isn't perfect but it works for my scenario

I'm making an assumption you are using a Pi 3.  The GPIO may be different if you are using an older version of the Pi

Hi,

I would like to connect an RPI to a Condor 16 transceiver. That is an

The raspberry pi would be running direwolf.

Now the audio-connection would be simply connecting pin 7+3 to audio-in
on the soundcard and 7+5 to audio-out of the soundcard (soundcard: a
usb sound module from china).
The ptt on the other hand is more interesting. I can use a GPIO pin for
that. I was thiking connecting 7+11 of the condor to a PC817 opto-
coupler and then the other end of the opto via a 220 ohm resistor to an
unused gpio pin.
Do you guys think this wil work? Anyone experience with this?

Can you connect to the apartment internet via wi-fi or only via a single network cable. secondly, if there is a router elsewhere in the building, not in your apartment and it supports dyanmic ip assignment, all you need is a switch or a hub.
if you're running a Windows machine.. to discover your IP addtess and if it "changes" (meaning it's dynamic)
PRESS START (Windows KEY) or Windows logo lower left side of screen or keyboard.
In the box, you can type in , type CMD <RETURN>
That brings up a DOS BOX... on the line type " IPCONFIG" <RETURN>
that will display information IPv4 is your IP address..  write your number down..
another command to see if you are all by yourself or with others and static or dynamic then type "ARP -A"<RETURN
Look for your IPv4 address and see if you are static or dynamic...
From there we can give you more help..
For instance you if your computer is connected via cable and it has wifi, doing nothing, we can bridge.. or we can bridge network to a USB cable..to the RPI..

I should point out that /dev/tty[dot]USB0 is not correct.  /dev/ttyUSB0 would be.

Hi Jonathan,

The device the command line is referring to is a 'tty' device that the OS creates when you plug your 7300 into the Pi.  If you unplug your 7300 and then plug it back into the Pi, you can run an 'ls -lrt /dev' and the device should show up at the end of the list.  It will probably be /dev/tty.USB0.

I haven't used Ardop in a while, but this is how I was able to get PTT working with my 7300/Pi:

piardopc 8515 IC7300 IC7300 --cat /dev/tty.IC7300:115200 -k FEFE94E01C0001FD -u FEFE94E01C0000FD

Note that /dev/tty.IC7300 is a udev rule, linking /dev/tty.IC7300 to /dev/tty.USB0 .  Don't use that device unless you have the same rule.  Like wise 'IC7300' is my ALSA alias, so continue to use the plughw references if they are working for you.  I can't remember how the '-k' and '-u' arguments work, but they somehow change the payload of the CAT command to allow the 7300 to PTT.  Hope this helps.

 I assume you are indicating that you do not have internet access.
Some digital modes require an accurate clock (+/- one second).
There are some internet services that augment some digital modes.

"Second I am disabled and low income. Can someone please help me out with this project? A screen, and keyboard is part of my plan."

Are you indicating that you cannot afford a Raspberry Pi, nor a monitor, nor a keyboard?

You will need an antenna. This assistance is most likely to come from a nearby ham.
I feel that you should 'reach-out' locally.

I added an FTDI chip to the one I built—mini din 6 to The FTDI chip to the USB plug. Works with my FT-818.

I do know there are USB to CI-V cables that basically have a USB to serial converter built into the cable. Perhaps this is the same type of cable but with a 6-pin DIN instead of a 3.5mm plug?

In Unix/Linux there is always more than one way to skin a cat.

To change the hostname, run the command 'hostname thenewhostname'.

To have it survive a reboot, edit the file /etc/hostname

Some Linux people like to argue what is the best way out of the many available.  If it works for you, that is the best way.
