Transmission starts, then stops after about 1 second #3

Closed WA6YDQ closed 1 year ago

WA6YDQ commented 6 years ago

Running the following command:

sudo wspr -n wa6ydq cm98 10 30m

Listening on 10.140, I can hear the transmission start. After a little less than 1 second, it stops transmitting. The program keeps running. This is the program output: WSPR packet contents: Callsign: WA6YDQ Locator: CM98 Power: 10 dBm Requested TX frequencies: 10.140200 MHz Extra options: NTP will be used to periodically calibrate the transmission frequency

When I run the test tone the same thing happens:

sudo wspr -n --test-tone 10140000 A test tone will be generated at frequency 10.140000 MHz NTP will be used to calibrate the tone frequency

Transmission starts, the after a little less than 1 second, it stops. Program continues to run.

So far, 30M is the only band tested.

Kurt, I just made some commits. Can you test with it ? What is your configuration system (Raspbian Lite version Stretch ou Jessie ?) : uname -a

WA6YDQ commented 6 years ago

Downloaded, re-built all. Deleted the 2 programs in /usr/local/bin, then ran sudo make install. Rebooted. Ran with no change. It still shuts off RF after a second.

uname -a Linux gadget 4.9.59+ #1047 Sun Oct 29 11:47:10 GMT 2017 armv6l GNU/Linux

I'm running a pi-0, not the w. Latest version of stretch, no other user-mode programs running.

I tried 30m, 20m, 15m, 10m. Above is the output of the 10m command. Starts up, then no output after a second or so. Program continues running.

I wonder if it is related to the new lib you wrote - I have the same problem running PiFmRds - on almost all frequencies it starts then shuts down, except on 91.5 MHz, where it runs correctly.

And I am running raspbian lite (stretch).

WA6YDQ commented 5 years ago

Just an update:

I am now using a new pi zero W with a different sd card and running stretch. uname -a: Linux gadget2 4.14.62+ #1134 Tue Aug 14 16:58:07 BST 2018 armv6l GNU/Linux

I installed WsprryPi per instructions. When I run: sudo wspr -t 146460e3 (146.460 mhz) I hear a tone for about half a second and the tone then stops, as before.

Edit: I am using I2C #1 to control a few devices (if that makes a difference). I also use I2S for audio playback.

I also installed rpitx and need the -a 14 option otherwise the pi zero stops and needs to be power cycled to come back to life. I don't see the -a option with WsprryPi. Is it needed? -kurt

F5OEO commented 5 years ago

Add gpu_freq=250 in /boot/config.txt should fix the problem

WA6YDQ commented 5 years ago

No change.

Here is part of my /boot/config.txt:

Uncomment some or all of these to enable the optional hardware interfaces

dtparam=i2c_arm=on,i2c_arm_baudrate=400000

for wspr (sw)

gpu_freq=250

Enable audio (loads snd_bcm2835)

dtparam=audio=on

dtoverlay=hifiberry-dac dtoverlay=i2s-mmap

This is the output from a run:

The transmission started, then locked up. A power cycle was required to restore the computer.

This is a pi zero w. I deleted all previous references to rpitx, WsprryPi, librpitx etc and did a fresh install per your instructions.

I tried again from the console, and after WsprryPi started, the screen scrolled up (very fast, could not see any error messages) and the kernel stopped responding to all input. A power cycle was required to restore the computer.

Any more information I can provide?

F5OEO commented 5 years ago

I2S confilcting with rpitx. For Wspr, I set it to use PWM to avoid it. Please test with latest commits (both Wsprpi and librpitx)

WA6YDQ commented 5 years ago

That seemed to fix it. When using a USB keyboard/hdmi for display, the WsprrPi program runs as expected. Thank you for putting the time into this!

One small issue - after WrprrPi completes sending a transmission, the wifi on the pi zero stops. Only a problem when connecting to it via ssh thru wifi.

I get these errors from /var/log/kern.log:

I am only using the built-in wifi. The only active usb device is a 32GB usb flash drive. I2S is not active nor is any I2C devices.
