Check the manual. ?I recall that there was an option to have positive keying as well (some rewiring may be required) -- 73, Bernie, VE3FWF

Re: Si5351A VFO/SigGen I2C Hardware question #vfo
Hans, Thanks for your explanation. I do understand your reasons. If I were doing a new design I would use the TWI/I2C port for a SI-5351 and the SPI port for an AD9850. The 49er DDS VFO uses a I2C/TWI

Re: U3s and the far east?
Hi Carl, When you say the dipole is arranged north and south, do you mean the wire runs along a north-south line? I am also in Maine. I am a DXer with several decedes of experience. It may be just

Re: U3s and the far east?
I don't use any of the'whisper' modes, but Japan to Eastern north America propagation is pretty difficult on the HF bands now. Steve Fabricant JS6TMW

Re: QCX and electronic keying
I don't understand that. The SB-104a and HW8 are SS. Where does the grid come in to play?

Re: Testing QRP Labs Si5351A Synthesiser Module, PCB Rev 4
Hello Joe The Si5351A chip has three stages conceptually: 1) Multiply the 27MHz reference crystal up to an internal VCO frequency, that theoretically must be in the range 600-900MHz 2) Divide down in

Re: QCX and electronic keying
The QCX keying requires a 3.5mm stereo bullet plug. For straight or bug semi auto keying connect to the tip and the body of the plug. Leave the second ring unconnected. And you'll be right!

Re: Si5351A VFO/SigGen I2C Hardware question #vfo
What you guess about the SDA/SCL lines is correct. I'm just wondering why so many people avoid using the I2C(TWI) interface as designed. I'm trying to learn how the Atmel I2C/TWI interface actually
