*** Cool instrument. I like that it has all those extra analyzers. Not very fast at 125Msamples/second though. It should be able to do up to 30MHz on the scope. I have a Hantek 2D72. It's a

If you want to purchase several instruments, consider Digilent's Analog Discovery 3 ( https://digilent.com/shop/analog-discovery-3/ ).? At about 4"x4"x1", it's great if you don't have a lot of

I have a similar signal generator, but the brand is "FeelElec" and the model is FY6800.? ?I have used it extensively for SSB transmitter testing.? It also functions as a pretty good frequency

Don't forget that most junior colleges and universities have EE departments, or at least physics depts that have all the test equipment you'd ever need. You can take your T41 to their labs and use

I have that signal generator and it isn't great. It's very noisy for low amplitude (<100mV) signals. It is useful for some quick tests, but you can't trust it at low signal levels. I've not tried to

I'm looking for test equipment suggestions. I have an oscilloscope, DVM, LCR meter but need enough equipment to at least finish this T-41...doubt I will live long enough to build anything more

This is a part of the code that I've not dug into in detail, so reader beware. If I understand the code correctly, you would need to do the following steps in order to have the default values in the

Jack, did you ever send out details on how to store the cal data on the SD Card?? I can't figure it out.? My SD Card shows "no files" when I connect it to my PC.? I know that you are at FDIM, so no

Larry, thanks for the pointer. The UHFSDR design is highly informative. j
