I've not tried testing this particular configuration, so I'm speculating here. If you don't have any receive circuitry populated then the only signal present to be digitized is the self-induced noise

The yellow LED next to the reset button on the Teensy board lights up brightly and dimly. And the audio is pumping most strongly on bands 17 and 15 at the same time. What's the problem? Only the

Yes. Great news Mark. Congratulations. It is an awesome milestone dave, n3ds

John - A signal generator has many uses.? I use one often.? But if you're goal is just finishing the T41, I would focus on the calibration directions (

I think that's right, see an earlier version of the schematic here:

I have the latest RF board from Bill and when adding the components, I noticed that C3, C14, C83, and C84 which are in the BOM do not have pads on the board...unless I missed something. Was this a

That's wonderful to hear, Mark! May it bring you many contacts and much joy.

Awesome!!

You can import signal files into Digilent instruments as well.? You can also create custom functions directly in the tool.? Here's my first attempt at creating quadrature two-tone signals. I still

Well, after a long, arduous (my opinion!) but enjoyable journey, I finally got on the air.? 10 watts, EPA into Southern Louisiana using a home brew 20M vertical dipole, thru 50' of coax.? RST of 52

Hi everyone, I am working on a stand-alone website devoted to the T41. It will go into the history , features, some technical stuff on DSP and SDR as well as a page(s) dedicated to users' builds. If

I Just a few boards left at Hamvention. When they are gone its back to mail order sales. Drop by and get what you need. Ps i also have 7 signed (by Jack and Al) third editions of the book available at

I actually wound up buying this: https://www.ebay.com/itm/164399483784?var=466700339663 Yeah, it's a bare board. But it gives a VERY clean synthesized signal. And it has an onboard attenuator...IIRC

*** I actually bought one of those on Amazon. While waiting for it to arrive, I did some more reading, and decided that I really didn't want it. Returned to Amazon, didn't even open the box. - Jerry,
