Once you've experienced the ~6dB gain of a hexbeam, you're station will be forever changed. You can build one from plans here: http://www.hex-beam.com/ . And, although the minimum height for optimal performance in 24', they work remarkable well at much lower heights. I'm sorry to hear that. I got my General license in 2012, and promptly erected a hexbeam and fan-dipole all by my self. (See: http://kj6yvt.com/hex-beam.htm ) It was difficult (and frightening) at my age. Now eight years older, I'm unwilling to risk the roof, so I am unable to make repairs. Congratulations. I passed both tests at one sitting too.

Re: Bluetooth...

Had similar problems when running Logitech wireless mouse and kb using fldigi and other apps. Wireless is power hungry and may be the problem. If you get a powered USB hub for the wireless dongle, that can make it work as well. Usually can find USB 2.x powered hubs for a low price on ebay or Amazon. Don't need USB 3 for wireless. Didn't have the problem when running LIbreOffice or other apps. Think it becomes an issue when processor is busy decoding the radio signals. Possibly someone more knowledgeable on RPi can expand this further. 73 Chuck KD9DVB

Thanks for all the info and the scripts. I should handle them easily with some practice. My Unix Command Line Skills have deteriorated over the last 15 years, with minimal usage. I may come back with questions as I get into it. 1st Priority is supervise my SIL install a 6 meter and 10 meter dipole, perhaps one to night and one tomorrow night. I was installing them along with a 20 and 40 meter on the roof. Then I fell down some steps on the 13th and broke some ribs. I got my tech and general tickets on March 14. The HF stuff is set up and awaiting a tuned antenna. I’d like to make a few contacts with Field Day, then work on the Pi stuff. de KE0ZUW John Nicholas Amateur Radio General Class Operator Member ARRL, Wichita ARC, & Air Capitol ARC Grid Square EM17im

Package Installation Scripts (Was: Re: [RaspberryPi-4-HamRadio] Brand New to Raspberry Pi)
On Mon, 22 Jun 2020 11:12:56 -0500, "John Nicholas"
<stnick@IWICHITA.COM> wrote: So when I decide to add an app to my collection. Do I add it via the etcher to the download, or onto the SD Card, or download after everything is up and runningHello John, Raspbian, a derivative of Debian, uses the 'apt' command, or the curses-based menu-driven 'aptitude' command-line package manager to add software packages to your system. You'll also find a GUI software manager in the applications menu-tree at the upper left corner of your desktop. You appear to be comfortable with the command-line interface, as am I, so below (and attached) are a few scripts I've written for my own use in adding packages. These are a bit crude, contain inconsistencies, and surely could be cleaned up and re-written in a more elegant manner, but I find them very useful none the less. The first is 'apt.sh' which I run to see if there are any updates available, before actually downloading a package: ----------------------------------------------------------------------- # apt.sh Initialize package handler # LGD: Mon Jun 5 11:58:39 PDT 2017 #set -xv # DEBUG LOGFIL="$HOME/logs/$0.log" [[ -d ${HOME}/logs ]] || echo -e "\n$0\: Log directory $LOGFIL does not exist$(exit 2)" >&2 # Check for internet connection STAT(){ ping -c1 -q 8.8.8.8 2>/dev/null 1>/dev/null ;STATUS=`echo $?` return $? } # Check for stale lock file LOCKED(){ LOCFIL=/var/lib/dpkg/lock if [[ -f $LOCFIL ]] ;then # Does stale lock file exist? ls -l $LOCFIL # Display lock file parameters read -n 1 CHOICE?"`echo -e \"\nRemove Lock File [Y/n/q]?\c\"`";echo # Prompt for user action case $CHOICE in q|Q*) exit ;; # Quit this script *) echo; rm $LOCFIL;return "$?" ;; # Remove lock file and return to caller with command status esac fi return 0 } LOCKED # Check for stale lock file until [[ $STATUS -eq 0 ]] ;do # Wait for network connection echo -e "Waiting for network connection." sleep 3 STAT done setterm -foreground green # Set text color to green echo -e "\n\tNetwork connection successful\n"; #setterm -foreground white # Set text color to white setterm --default # Set terminal to default values aplay -q /usr/lib/libreoffice/share/gallery/sounds/apert.wav # Announce successful network connection echo;date +%A", "%B" "%d", "%Y" "%R read -n 1 CHOICE?"`echo -e \"\nUpdate apt package system before continuing [Y/n]? \"`";echo case $CHOICE in [nN]) exit ;; # Don't update *) echo -e "\n##### `date` ####" >> ${LOGFIL};apt-get update 2>&1 | tee -a ${LOGFIL} && apt-get --show-progress upgrade 2>&1 | tee -a ${LOGFIL} ;; # Update esac read -n 1 CHOICE?"`echo -e \"\nUpgrade Debian system before continuing [Y/n]? \"`";echo case $CHOICE in [nN]) exit ;; # Don't upgrade *) date >> ${LOGFIL};apt-get --show-progress dist-upgrade 2>&1 | tee -a ${LOGFIL} ;; # Ugrade esac ----------------------------------------------------------------------- Between the effects of word-wrap and Windows Carriage-return, Line-feed convention to end lines, the above will require some editing to use. The attachments won't have those issues. The next script, 'show.sh' is used to query the package database to find if it contains a package supplied as an argument after the command itself. I often find it useful to append a '\*' after the package name to display package name variants. ----------------------------------------------------------------------- #! /bin/ksh # show.sh Display package information # # LGD: Sat 25 Jun 07:56:55 PDT 2016 # LGD: Mon 13 Feb 16:23:15 PST 2017 Added smart-pager support # if [[ $(tty |grep pts) ]] ;then export LESS="-P\ ?f%f .?n?m(file %i of %m) ..?ltlines %lt-%lb?L/%L. : byte %bB?s/%s. .?e(END) ?x- Next\: %x.:?pB%pB\%..%t (pts`tty|cut -d/ -f4`) " else export LESS="-P\ ?f%f .?n?m(file %i of %m) ..?ltlines %lt-%lb?L/%L. : byte %bB?s/%s. .?e(END) ?x- Next\: %x.:?pB%pB\%..%t (`tty|cut -d/ -f3`) " fi # USAGE: Multi-package search not yet implemented [[ $# -lt 1 ]] && echo -e "\n\tUsage: $0 [package name] \<package name\> \<...\>\n" >&2 && exit 1 LOGFIL="$HOME/logs/$0.log" [[ -d ${HOME}/logs ]] || echo -e "\n$0\: Log directory $LOGFIL does not exist$(exit 2)" >&2 #set -x SRCH=$(echo "$@"|sed 's/*/\\\\*/') # Escape * so shell doesn't show filenames FOUND=$(/usr/bin/apt-cache show $SRCH 2>&1) # BUG: Fails to assign value to $FOUND #FOUND=$(/usr/bin/apt-cache show "$SRCH") if [[ `echo "$FOUND"|grep "purely virtual"` ]] ;then # BUG: This fails to display output echo "$FOUND" >&2; exit 1 elif [[ `echo "$FOUND"|grep "No packages found"` ]] ;then echo "$FOUND" >&2; exit 1 else # Only pipe output through less when necessary [[ `echo "$FOUND"|wc -l` -gt 30 ]] && echo "$FOUND"| less -p 'Package:' [[ `echo "$FOUND"|wc -l` -le 30 ]] && echo "$FOUND"; exit fi ----------------------------------------------------------------------- You'll notice that I'm using the Korn Shell (ksh) command-line interpreter. If you want to use it, you'll have to install it with: 'apt-get install ksh' first. Otherwise, I'll leave the editing to support bash or sh as an exercise. :-) I like 'ksh' because, it supports 'vi' command-line editing and floating-point math, and it was what I learned back in the '80s. And finally, here is 'get.sh' to actually install the package: ----------------------------------------------------------------------- #! /usr/bin/ksh # # get.sh Install packages # # A front-end for 'apt-get' that provides package installation information before installing packages and logs actions # # LGD: Sat 25 Jun 07:56:55 PDT 2016 # LGD: Tue 05 May 2020 10:43:28 AM PDT: Bug fixes and enhancements # # Check for positional parameters [[ $# -lt 1 ]] && echo -e "\n\tUsage: $0 [package names]\n" && exit 1 # Set variable values and verify log file structure PROG=$(basename $0) ARGS="$@" LOGDIR="$HOME/logs/" LOGFIL="$HOME/logs/$(basename $0).log" # Check for existence of log directory and writable log file if [[ -d ${LOGDIR} ]] ;then : else echo -e "\n${0}: Log directory $LOGDIR does not exist." >&2 exit 2 fi if [[ -w ${LOGFIL} ]] ;then : else echo -e "\n${0}: Log file ${LOGFIL} does not exist or is not writeable." >&2 exit 3 fi echo -e "\n${PROG}: Working.

This can be useful when the output scrolls too fast to read, and as a record of what you've done. Finally, I put the name of this file '.fun' in my '$ENV' file so that it adds a few useful functions to my environment. The 'd' function can be useful for navigating convoluted directory structures. ----------------------------------------------------------------------- cls(){ tput clear cd tty } u(){ cd .. } d() { if [ "$BASH" ] && [ "$BASH" != "/bin/sh" ]; then echo "$FUNCNAME: ksh only";return 1 fi FIGNORE= # ksh93 equivalent to bash shopt -s dotglob if [ ${#} -gt 0 ] ;then # Only one command line argument accepted cd -- "$1" && return 0 fi if [ `ls -AF1|grep /|wc -l` -eq 1 ] ;then # cd if only one subdirectory cd -- `ls -AF1|grep /` && return 0 fi destdir=$( while :; do subdirs=( ~(N)*/ ) # ksh93 equivalent to subdirs=( */ ) with shopt -s nullglob (( ${#subdirs[@]} > 2 )) || break # . and .. are two entries echo -e "\n\t\tSubdirectories below ${PWD}: \n" >&2 for idx in "${!subdirs[@]}"; do printf '%d) %q\n' "$idx" "${subdirs[$idx]%/}" >&2 done printf '\nSelect a subdirectory: ' >&2 read -r if [[ $REPLY ]]; then cd -- "${subdirs[$REPLY]}" || break # Continue to loop through subdirectories after cding else break fi done printf '%s\n' "$PWD" ) [[ $destdir ]] && cd -- "$destdir" && return 0 } f(){ echo -e "You have these functions in your environment:\n" typeset +f echo } alias rm="rm -i" alias cp="cp -i" alias mv="mv -i" alias ls="ls --color" alias date="/bin/date '+%_A, %B %-d, %Y %H%M %Z'" ----------------------------------------------------------------------- Of course, you'll have to enable execute permissions on these script files before you will be able to run them: chmod 755 apt.sh show.sh get.sh Have fun, and if you improve my scripts, please e-mail a copy to me: LDighera@att.net Best regards, Larry WB6BBB PS: I was chatting with a fellow on 40-meters the other day, and happened to mention that this pandemic means "Bye Bye Boomer," and cleaver fellow, he said that made a good mnemonic for my call. :-)

Re: Tnc-x PI
Tim I finally see what you meant by Note Note added 12/4/2018: Some individuals have reported that there is a problem
with the November, 2018 revision of Raspbian that results in the serial port not
being accessible. You would notice this, for example, if you run pitnc_getparams
and you keep getting “retrying…” instead of the menu. In this case you need to edit
the config.txt file in the /boot/ directory. You can do this by running the following
from the command line:
sudo leafpad /boot/config.txt
Add the following line at the bottom of this file:
dtoverlay=pi3-miniuart-bt
This problem seems to be fixed with more recent versions of the Stretch version of
Raspian. Thank You. I thought Buster would have fixed that issue. 73 Don va7dgp/va7qu

I'll add I didn't realize this issue was on HamPi. That makes remote digi extremely difficult if your GPS can't provide a clock. Very disappointing. Hope more users than Tim are trying to figure this out or have figured it out. It's a no go for me if I can't use the GPS dongle. Just gave to stick with the old 2.0 as I'm not savvy enough to figure it out.
Thanks for all your hard work Dave. I'm running your 2.0 so since it ain't broke I'll hang on to it for now.

2400 baud with Yeasu/Vertex FTL-1011
The Yeasu/Vertex FTL-1011 vhf-lo (6m) (and probably the 2011, 7011 radios for 2m, 70cm) seem to work with 2400 baud. They aren’t quite as noise immune on 2400 as on 1200 but the 6m version is really cheap! https://www.ebay.com/itm/Vertex-FTL-1011-VHF-FM-Transceiver-FREE-SHIPPING/282346444832. They do 35watts @51mhz and easily tune to the 1.5mhz of the 6m band. Some of them work higher in 6m band.
