Re: New file uploaded to Raspberry_Pi_4-Ham_RADIO
Following is an example of script that makes the Raspy able to say, via radio, its core temperature and load.
It uses nbfm.out as FM transmitter and festival as speech synthesizer. #!/bin/bash if [ -e CPUTemp.txt ]; then ??? rm -f CPUTemp.txt fi clear inp1=$1 inp2=$2 if [ -z $1 ]; then ??? echo "" ??? echo "NBFM Transmission of the CPU temp and load, v20140725 by IK1PLD" ??? echo "" ??? echo "Use: ./TX-CPUTemp.sh [Freq [Interval]]" ??? echo "Freq: carrier frequency in MHz (example 145.3125)" ??? echo "Interval: time interval, in sec, between transmissions (default 60)" ??? echo ""?? ? ??? exit fi if [ -z $1 ]; then ??? inp1=145.5 fi if [ -z $2 ]; then ??????? inp2=60 fi echo "" echo "CPU temperature and load is transmitted on $inp1 MHz every $inp2 seconds" echo "" startN=1 while [ $startN -le 1000 ]; do ??????? temp_gpu=$(/opt/vc/bin/vcgencmd measure_temp | tr -d [a-z,A-Z,"=","'","."][]) ??? ?? ?cpuUsageM=$(top -bn 1 | awk '{print $9}' | tail -n +8 | awk '{s+=$1} END {print s}') ??? ?? ??? ?cpuTempString=$(cat /sys/class/thermal/thermal_zone0/temp) ??? ?? ??? ?cpuTempInt=$(($cpuTempString/1000)) ??? ?? ??? ?cpuTempDec=$(($cpuTempString/100)) ??? ?? ??? ?cpuTempDec=$(($cpuTempDec % $cpuTempInt)) ??? ?? ??? ?cpuTemp=$cpuTempInt$cpuTempDec ??? ?? ?let cpuTemp=(${cpuTemp}+${temp_gpu})/2 ??? ?? ?TempCoreInt=${cpuTemp:0:2} ???????

Re: New file uploaded to Raspberry_Pi_4-Ham_RADIO
As for an example, if you wish to transmit the audio file "cq.wav" (sampled at 11025Hz) on 145.500MHz with a standard 5kHz deviation and no frequency correction, no subtone, you can simply type:
./nbfm.out cq.wav 145.5 Another example, using a subaudio tone: ./nbfm.out cq.wav 145.5 11025 -15 5 400 0.01 110.9 It means to transmit on 145.500Mhz the audio file "cq.wav" sampled at 11025Hz, applying a carrier frequency correction of -15ppM, FM deviation of 5kHz, 400us pre-emphasys, adding a 110.9Hz tone with 1% of full scale level. 73s de ik1pld |

Hello,
This email message is a notification to let you know that a file has been uploaded to the Files area of the Raspberry_Pi_4-Ham_RADIO group. File : /nbfm.out Uploaded by : fotograf_ale <fotografale@...> Description : This is a Narrow Band FM transmitter derived from pifm. It is able to transmit FM from VLF to UHF with a settable deviation and pre-emphasys, frequency correction and subtones. It runs under debian distr. In a SSH session type ./nbfm.out for help. It could be useful for beacons, fox hunting but also as a laboratory instrument to check and calibrate receivers and IFs since it can operate at, for example, 455kHz, 10.7MHz, 21.4MHz and so on. Over 150MHz it needs to be run in 3rd harmonic; doing so it is possible to use it, for example, on 220 and 430 MHz, paying attention to reduce the deviation properly. IMPORTANT NOTE<This program uses the classic GPIO4 (pin7) as RF output port. The GPIO generates a lot of spurs and harmonics all around the spectrum. A filter is absolutely needed if you intend to radiate the signal on air without the risk of causing serious frequency pollution and disturb important radio communications. enjoy the nbfm transmitter and best 73s ik1pld You can access this file at the URL: To learn more about file sharing for your group, please visit: Regards, fotograf_ale <fotografale@...> |

Raspberry Pi and FCDpro+
Hi,
I just purchased a Pi B+ with the intention to construct a server for my FunCubeDongle pro+. As I have seen many applications using cheap RTL dongles I wanted to use a FCD as of its higher quality of reception but had comments by several ham's that they were unsuccesfull at making the FCD work with a Pi. It is my intention to just pipe the I/Q data via ethernet to my home network and control it via a dedicated sdr software as I suspect that the computing power of the Pi is to slow for controlling the FCD directly. I'm completely green to all things related to the Pi so I can need al the help. Hopefully my Pi will be delivered next monday. All info is welcome. Best regards, Ron ON2RON |
