OK here is the tool and process I use.
First Off! The Standard Disclaimer: I switched 100% to Linux when Win 7
came out. I can't help much with a Windows os and not at all with Mac.
I requested an enhancement to this tool back in 2019. The resample
option was added and up till now, has worked every time. Last night I
was running it on my Kiwi and the resulting file was 6011 sps. Argo must
have exactly 6000. I re-run the script this morning and on my Kiwi I get
6011, on a remote Kiwi - same script, I get 6000. I don't know what
the issue is. Just when I thought I could share this capability.... My
script is good, but the software may now have an issue.
****************************************
The software to use can be downloaded from here;
https://github.com/jks-prv/kiwiclient
That software works as documented on Linux. It is written in Python and
should work on Mac and Windows. The documentation is contained in the
readme.me and the included Makefile. Follow the installation
instructions. Some additional components are required.
Now for my part, here is the Linux script I use to make a .wav file.
#! /bin/bash
FREQ=184 # frequency to tune. Hifer use 13554
IPADDR=192.168.0.9 # my local kiwi, but this can be a real URL
# like vexxxx.ddns.net
KIWIREC=~/kiwiclient101023 # This is the directory that I expanded the
# downloaded zip file to.
OUTFILE=~/capture/n8oou$(date +%Y%m%d_%H%M%S) # this is the file to
# input to Argo.
# (.wav auto added)
echo "capture $FREQ at $IPADDR to $OUTFILE"
python3 $KIWIREC/kiwirecorder.py -s $IPADDR -p 8073 -f $FREQ -m USB -u
MyCall -L -300 -H 2000 --tlimit=60 -r 6000 --fn $OUTFILE
# Note change MyCall to your call or nickname
# End Of Script
**************************************
In Argo, click Setup, Select input, Open WAV File.... Once file
processing starts, let it finish. Argo is fussy about file input and
will hang up.
I hope this is enough info for you guys to run with.
Good Luck
