FT817ND is a Swiss Army knife of transceivers. You don't need many radios, just 1 radio such as 817 or maybe even Icom IC703 QRP. If you want more power, just hook up a HF amp. I use Tokyo Hy-Power 45B amp inline to help me with contacts when operating from a base station. For SOTA/POTA activations, I just use it with my trusty LDG Z817 tuner. Will never sell mine for anything else and any additional bells and whistles with a more expensive rigs are very marginal.

This receiver is sensitive. Connected my QSX+ and FT818 on the same antenna with a Y. They heard the same signals equally. Hard to tell even on the weakest signals. I have to recommend the QCX+ Very Highly.

HI again, When using the module in the video to light up an LED strip, it works, but it's much less bright than when powering the LED strip directly. I'm using the supplied 12v power supply to power it and it's super bright when powered directly but only maybe 30% of the brightness when activated by the PIR. It turns out that the 10k resistor is only allowing 7.4v to get to the LEDs when they want all 12v coming from the power supply. I jumpered the resistor and it's as bright as it is when powered directly from the psu and working great!.

HI, Is there a pir that sends a signal for 1 second only when motion detected and another signal when it times out from the same output? I would like to make a simple motion detector to turn my video camera on and off. I aready have a remote controller for my camera with a spare transmitter and the one button turns the camera on and off. I could use the transister to operate a relay to short out the switch in the transmitter. Great video. Thankyou.

Would it not make sense to calibrate at a much higher frequency? I would think higher frequencies (like 4x your maximum expected operating frequency), the total error at lower frequencuiies would be almost a non-issue. Also, are you using a TCXO on the Si5351?
@Q26Video 3 ай бұрын
Hi Tim - I'm following the guidance of NT7S (Jason) and his etherkit library for Arduino and Si5351 - his calibration sketch shows an example of 10MHz and that worked really well for me. I also tried at some other frequencies, eg in the 14MHz band. Getting an accurate zero beat to work another station is really important for QRP and the point of this video is to show it can be done even without specialist equipment (and I did improve on it off camera 🤓😃). 73 from Mort / G4BSK

@@Q26Video Thanks for indulging me. One other question I was not able to answer from a slightly more than cursory read of the datasheet - what is the VFO adjustment range of the analog input, and do you have any experience with the transient response of that SI5351 part? I am curious if that would be suitable for an OFDM transmitter (by directly modulating the VFO input with an external DSP, like say an ESP32).

@Q26Video 4 ай бұрын
A common misconception, Lars - most of the contacts I make are with other stations with low power equipment and simple antennas - usually a wire in the garden or a dipole. I have worked stations all over Europe with less than 1/2 watt and many of them have been similar, usually 5w or less. It's a very exciting and satisfying way to enjoy the radio hobby and the idea that it can only be done if one side has a super duper antenna does not stand up to the facts...give it a try - put the huge rig and beam in a cupboard and have fun with QRP! 73 😃
