If you are trying to copy wspr mode , as that is the mode you are set for,

the screen does not look like a clean signal of anykind. perhaps check 10.140 if you have a 30m antenna also are you on usb?? Dave Garber VE3WEJ / VE3IE On Thu, Sep 22, 2022 at 6:16 PM Gilbert Baron <w0mn00@...> wrote:

For one thing, your clock is off by about one minute.

I am using a Red Pitaya to transmit WSPR. I am using a PC that is connected to the internet through WiFi. The Red Pitaya is connected to the PC using an Ethernet cable. The Red Pitaya is running the Alpine OS and NTP is being used to sync the time.
I will see if NTP is working on the Red Pitaya. Thank you |

The Red Pitaya is running the Alpine OS and NTP is being used to sync the time.The link as such gave the relevant information, actually I did not noticed those ads at first look at all! Your signal has a very strong 120 Hz amplitude modulation and some 60 Hz as well. Is your power supply working properly? Even that may affect to the signal quality. In any case it may not be suitable for a public transmission due to the 120 Hz sidebands. You should have only a single line at 1500 Hz. I will see if NTP is working on the Red Pitaya.If your example presents the proper start of the signal, then either the transmitter clock or PC (?) clock is not aligned properly as the signal should to start at an even minute mark. 73, Reino OH3mA |

Hi Paul,
Ok first, you have a severe 60 Hz NOISE on your signal! I.e. all of those vertical lines spaced 60 Hz apart. Looks like bad filtering on your power supply. Try powering with a battery & see if that goes away. Check your clock to. |

And before that transmitted signal with all the IMD products started, there was no sign of any signal, not even band noise. It looks as if the receiver audio was not reaching the sound card, the wrong sound card input was configured, or maybe the antenna was disconnected.

My issue is now resolved. I needed to enable Network Time Protocol(NTP)
I am transmitting about 8 dBm. My call is KI5MIV. Check me out today on 20m. I am amazed at the distance of stations that can hear me using WSPR! Thanks everyone! |

Hi Reino
Thank you for providing advice! Please excuse my ignorance on WSPR and WSJTX - I am learning! How can you tell I have 120hz and 60hz AM? Thank you again! Paul |

How can you tell I have 120hz and 60hz AM?Hi Paul, The spectrum has higher peaks at 120 Hz steps from you wspr carrier at 1500 Hz. How those go down with the distance from the carrier tells that the AM modulation mostly contains a short amplitude change lasting say less than a few milliseconds and repeating at 120 pulses/s. There is also a smaller amplitude component at 60 pulses/s. Probable reason is full wave rectification in the mains power supply and may also be sawtooth shape due to insufficient DC filtering, perhaps too small capacitance. If you have an RF amplifier that is working at saturated power, then the ripple in the DC voltage directly modulates the RF amplitude. As proposed you could try some battery as the power source to see whether those sidebands are removed. If you try FT8 mode, then your sidebands will have the same 50 Hz width as the main signal. 73, Reino OH3mA |

Paul, I use AdBlocker+. It keeps websites ad free so when I download a photo, either by right-clicking it to copy it and then left-clicking to save the image to my folder of choice or I use a small free program from IObit software called iTop Screenshot that works great. Pressing ALT+A on the keyboard activates it with a large square I can move over the image and crop from either of the 4 sides of the image and when I finish cropping it and release the left mouse button a window pops up with the choices of Copy or Save. I usually copy the photo and then paste it into PhotoScape, a great free photo editor, and save it after any edits I do to the original image. Best of all no ads! PhotoScape also has a clone feature that can be used to hide any ads that appear directly on the photo.

I use a browser called "Brave" - same as Chrome but blocks ads. Especially great with Youtube and their ads.

For page/photo copying, if you are using Windoze, just use the snipping tool On Sat, Sep 24, 2022 at 05:33 PM, Cliff Fox (KU4GW) wrote:
