OK. I have refreshed my system with the V15 image and am back to the
same problem on HF as stated before (no pwer out or rig key on FLDigi,
WSJTX, JS8Call, etc.).

Pick one program at a time, for FLdigi using a DRAWS hat:

Fldigi configuration ->Rig->GPIO

Select BCM 12 for left mDin6 connector
Select BCM 23 for right mDin6 connector

Read this for reference:
https://nw-digital-radio.groups.io/g/udrc/wiki/UDRC%E2%84%A2-and-fldigi-Setup-Page#Set-up-PTT

Here is what I reassembled and making an
assumption of what commands you would want to see:

NOW an unsolved mystery. With the same IC-7000 and ax25 stopped via
the AX.25-control script I can’t get WSJTX, Fldigi, JS8Call to key
the transmitter and send audio. Running
n7nix/deviation/measure_deviate.sh –c left keys the radio and I get
power out (modulated rig input). Issuing the measure_deviate –c left
–l 5 doesn’t key the transmitter for 5 seconds – it just keeps going
for the full 30 seconds. So this utility can key the transmitter with
audio input to the transmitter.

When I try JS8Call, WSJTX, FLDigi the transmitter is not keyed or
audio sent to the Mic in. I am using FLRig for the radio interface
BUT PTT is turned off in FLRig (no CAT/RST/DTR etc). FLRig is talking
to the radio OK (reading VFO/Mode)

For JS8Call the settings are: Radio Rig-FLRig FLRig, PTT VOX, Mode
USB, Split none. Audio input is plughw:CARD=idrc,DEV=0 and output the
same. The software reads data from the radio just fine and decodes
OK. Pressing the Tune button gives indication from the software of
transmitting (Red Tune button and TX button red) but the radio isn’t
keyed or transmitting.

Similar things are happening with FLDigi (receives/decodes OK but no
transmission). It is setup as rig control by FLRig and FLRig not
keying the modem. Soundcard devices has PortAudio selected with
Capture: udrc:bcm2935-i2s-tlv320aic32x4 hifi tlv320aic32x4-hifi-0
(hw: 1,0) as the only option to choose from and Playback the same
only there are 4 options here (alsa0,1 alsa 0,2 dmix). Hitting the
Tune button on FLDigi gives the indication from the software that it
is tuning or transmitting text (in the waterfall) but the rig doesn’t
key or transmit.

Awesome!! So is the hostap mode part of NWDR image and how to enable
it? That is WiFi without my home router correct/ hotspot is that the
correct term?. I tried to do a hotspot switch from other instructions
and only partly succeeded. If it is already part of NWDR XX I don’t
need to do anything? Thanks Basil.

Basil, when you use nixtracker mobile, what are you using for a display and is it hardwired to the RPi or not?

Basil or other gifted scripting author,

This is just a thought

If there was a first release of the new year that was going to SIGNIFICANTLY be a game changer, this is it. !!!!

Missing from your scripting is that Holy Grail Script that when run archives the configuration of the of all the installed APPS and the image configuration.

I only wish that I was a script coder that could write a script that would do that archive the configurations, AND also RESTORE the configuration from previously archived configurations.
alas, I am not such a gifed coder and at the mercy of those who are.
ie.
buconfig -l
This simply lists that configuration date and times that configurations were archived.
buconfig
when run without arguments, stores archived versions of the configuration files
buconfig -a -s /home/notmypi/
when run with the -a "archives the current configuration settings" and -s specifies the directory location that the archived configurations are stored.
"normally" the archived configuration files are stored in /home/pi/archivedconfigs
buconfig -r -d 2020-01-24-00:00
when run with the -r it restores the most recently saved configuration files
or when the -d specifies the date or date time, it restores the most recently saved configuration files after the specified date or datetime.
-----------
-s -d and other program flags can be used together to maximize the effectiveness of the configuration archive and restoration.
when run with flag "buconfig -a -d 2019-12-31" would archive the current configuration files stored as archived on 2019-12-31-2359
as to represent the last configuration for the year 2019.
