I now have a TM-V71a connected to my UDRC and am trying to get rigctl to work with it. I have an equivalent of a PG-5H connected to a serial/USB converter enumerated as /dev/ttyUSB0. My first test of the cable was with chirp and it seems to work fine. 

When I try ""rigctl -m 234 -r /dev/ttyUSB0 -vvvv", I see multiple read_string timeouts and then rigctl enters command mode. When I try "f" to get the current vfo frequency, I get multiple read_string timeouts and finally "get_freq: error = Communication timed out". 

Are there specific serial params needed to talk to the V71a? (e.g. RTS/CTS flow control, specific baud rate)?

Thanks for any help!

I’ve been booting from the external Toshiba 500gig USB drive for years but the Pi still needs /boot on the SD card to read the configuration then continues booting from the external drive.  In your case are you saying the SD card is completely eliminated if the PiDrive is used ?

Building the external boot is not too hard: DD the SD image to the HD then figure out the Linux ID of the external HD, edit I think it is /boot/config.txt with the external ID and reboot.  I wrote up the routine on the rasperry pi forums long ago but it should still be there, search boot external hard drive.      Bill acj

I feel soooo bad you guys. I  have not updated this for you. I did get my draws hat working fine on the new PI3B+. It is working just fine. I never tried again on the piDrive as it was working with the new PI and I wanted to play for awhile. My HF rig just bit the dust yesterday and I have to send it off for repair. So now is the time I guess to try the piDrive again. I do want to make that work because of the elimination of the SD Card requirement. With the PiDrive you can boot from the harddrive. I was hoping to be able to do the same with Compass Linux. So we shall try sometime this week and see what happens again. Wish me luck.

Verify the DRAWS hat
--------------------
Disconnect the cable from your radio but plug into DRAWS hat
on the open connector put your volt meter on what you think is the PTT pin

Manually turn the gpio for PTT on & off

Left connector:
PTT On:
gpio -g write 12 1
PTT Off:
gpio -g write 12 0
PTT Check:
gio -g read 12

Right connector:
PTT On:
gpio -g write 23 1
PTT Off:
gpio -g write 23 0
PTT Check:
gio -g read 23

Verify your radio
-----------------

Disconnect the cable from DRAWS hat & connect to radio.
Ground the pin you think is the PTT pin ... did your radio transmit?
Un-ground the PTT pin ... did the radio stop transmitting?

To debug PTT issues:
Use the 'How to use measure_deviate.sh' notes here:
https://github.com/nwdigitalradio/n7nix/tree/master/deviation

Use left & right connector locations and either tune a second radio to
the same frequency as your test radio so you can hear the tone or watch
your radio to see if it transmits. If that doesn't work you have a cable
problem.

So far I can receive only.

I'm getting a little screwed up in the pin labeling and what side of the cable I'm on.

What I have so far:

Cable from DRAWS w/end cut reveals

Pin 6 Green

Pin 5 Black

Pin 4 Orange

Pin 3 Yellow

Pin 2 Brown

Pin 1 Red

Radio uses an RJ-45 MIC cable and a speaker audio

Pin 1 N/C

Pin 2 DC 8V

Pin 3 GND

Pin 4 PTT

Pin 5 GND (MIC)

Pin 6 MIC

Pin 7 N/C

Pin 8 DTMF Data

Plus TRS on rear audio 1/8th jack

I have

DRAWS = Radio

1 = 6

2 = 5

3 = 4

4 = N/C

5 = Rear Speaker TIP

6 = N/C

GND = N/C

Any thoughts?

6 pin mini-din or other?

1200 baud and/or 9600 baud?

You are comparing apples and oranges. The "Data Port" on ham radios is a
misnomer. It is a port for audio connections, just like the microphone
jack. It typically has PTT, TX and RX audio (often from two locations in
the radio for wide/narrow audio bandwidth), COS, and other signals. This
is designed to use with some hardware interface (TNC, modem, etc.) or
sound card (Signalink, etc.) device. Your USB connectors are for just
that, USB connections for power and data transfer. Trying to use a
mini-USB (4 pins) connector or micro-USB (5 pins) for an analog signal
cable is a recipe for disaster.

When manufacturers first started interfacing with radios, they simply
used the microphone connector. This often required the use of an
external switch box go go between the TNC and the microphone so the
radio could be used for dual purposes. Then, users wanted to hook both
devices simultaneously, plus wanted added features (discriminator tap
for UHF packet, COS, etc.) The mini-DIN 6 pin connector was an industry
standard at the time, used for PS/2 connections to computers and other
purposes. Readily available, inexpensive, smaller than Molex or DB
connectors, it was a good choice and became somewhat a standard for the
purpose.

So, hopefully, that may answer your "Why do so many of you want a DIN-6
port?" question.

Your other comments regarding the different HT/computer interfaces,
compatibilities between adapter/OS, drivers, baud rates, etc. are a
totally different issue. That is regarding purely data interfaces via
USB and converted serial data. Completely irrelevant to the conversation
at hand.

I just plugged the harddrive into a USB port on the Pi3. I now get the lightning bolt when the drvie is accessed. When idle the lightning bolt is not on. So it is working but un-sure at this point about other devices. I will run it this way over the weekend to see if it holds up. I do see all of the partitions I built with the WDLabs image so that is cool. I am running the beta13 image right now. I have mis-placed my ps2 female pig tail. When I find it I will solder up a connector for the 2m rig and see if I have enough power to drive the radio audio. More to come.
