PCM Frequency out of range #4

Closed ZS6RAS closed 5 years ago

ZS6RAS commented 6 years ago

Please can you help me.

I installed WsprryPi yesterday and every time I try and run a transmission this is what I get:

sudo ./wspr --repeat --offset --self-calibration ZS6RAS KG44 20 40m WSPR packet contents: Callsign: ZS6RAS Locator: KG44 Power: 20 dBm Requested TX frequencies: 7.040100 MHz Extra options: NTP will be used to periodically calibrate the transmission frequency Transmissions will continue forever until stopped with CTRL-C A small random frequency offset will be added to all transmissions

I am using a Raspberry Pi Model 3B and RASPBIAN STRETCH LITE.

It seems that PLLD is at 1ghz instead of 500Mhz. Maybe you have mixed with rpitx master branch which modify PLLD frequency(use v2beta of rpitx). Solution is to remove /boot/dtblob.bin : sudo rm /boot/dtblob.bin

Let me know.

ZS6RAS commented 6 years ago

I have removed the dt-blob.bin file from /boot but still have the same issue. Is there anything else I can try?

ZS6RAS commented 6 years ago

Sorry I looks like it worked after a reboot. Here is what I ran, does this mean it is working?

Yes, should Be OK. Have you try to décodé output?

Yes and it decoded. But only once. Is it normal that it is non stop transmitting? WSJT-X transmits from 0 to 110sec.

This is what I get when I transmit and only decode once:

And then it just hangs at TX started at: UTC 2018-07-08 18:04:01.001 and does not do anything further.
