¿ªÔÆÌåÓý

I have made my own version of these.? They work fine on a Nano, but since there is NO Address selection it probably collides if you put it on Raduino with its SI5351.

The 20 Pin version of the SI5351A has ONE address selection pin, so the next ones I make with be with the 20 QFN part.

It is over 2 the price and in the QFN package.

Not coming off the Raduino, I'm using one of these:



Much simpler but does the same thing.  My own Nano connects to it without
the need for a display.

thanks.   I assume you measured right at the output of the radiuno and not
after the 6db attenuator.

I'm hoping to use this thing as a replacement VFO for some old heathkits
once I learn what THEIR vfo output voltage was.....I'm pretty sure they
were at 2K ohms so I may be able to use a ferrite transformer and step up
voltage through simple impedance matching.     It would be really cool to
have the advantages of the digital VFO on my old (and EMP proof)
SB-102!!!!

measured where, across what impedance?
thanks for the information!!!
Typically my RF measurements are all at 50 ohms, but right now I can't say
for certain that last nite's were.  I'll have to double check when I get
home.  Also I need to correct something, my initial output was 4ma, not
2ma.
