You have to choose between the ATTiny85 part of the circuit and the reverse polarity protection part -- you can't install both parts because they will interfere with each other. If you install the

Fellow ham and I are starting the main board consy. Following Dr. Bill's comprehensive instructions we are a little confused regarding the use of Reverse Polarity Protection along with the TTiny85.

I've successfully used WSJT-X with Windows 11 with the T41 passing audio over USB along with control signals.? I patched the 192 kHz sampled audio to an AudioOutputUSB and it is transferred to the PC

I looked at this myself. I dont think it makes sense to run the complete radio that way… rather you would take the I/Q input and outputs from the RF board straight into the appropriate audio card in

What version of code are you modifying? Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ Owner - Operator Big Signal Ranch – K9ZC Staunton, Illinois Owner – Operator

Remember… you CAN use canned smd inductors and variable caps if you want to save time. You still have to tune the filters though. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ

Jack, your board looks great! Russ NQ0U

Bill, please put me on the list for: 1ea. 20A and 1ea. 50A 2ea. Power distribution kits 1ea. AT Tiny ?? Attenuator chips (however many I need for a V.12 with 2 receivers) 1ea. LC Meter I’m not in

Again, I'm really bad at EE topics, but in all fairness, Al designed the T41 ADC processing 5 years ago and COVID was just starting to rear its ugly head. At that time, some high performance ADCs were

Hello all, As you may remember, I fried my display :(. A new one is on order from BuyDisplay, but now I can't continue bringing up the rest of the system. Sigh. Just for yuks, I also ordered a few

Hi Ken, I've done that with an SDRPlay.? I was able to get several MHz of bandwidth and demodulate using GNU Radio. -- 73 Greg KF5N

By no means ready, but I have been playing with using the ethernet interface to stream I/Q data. I have a lot of experience with the HPSDR protocols so that is what I am emulating. -- John G0ORX

I was wondering about using the USB interface on the T41 as a "sound card" interface.? Then you could plug the T41SDT into your computer and run GNU radio.? Now I know the whole idea behind the

T41EEE.7 branch cessb1 has new commits to simplify the main loop() state machine. The modal state machine has been a sort of hybrid between the original T41 code and changes which were made for the

Oh, that's too bad it is that restrictive.? I will add an experiment to my list for the future to try to run the receiver at 44.1 ksps.? I think there may be some extra work due to the display

I bought this pack for $10 on Amazon (B0B82L2YWB): I used the 2.5mm (yellow above) for the T37 cores. I got the pack because I will be winding other (larger) cores later on. The case is zipped and

Greg, I'm only talking about (lifting) the restriction on usb-audio, where the Teensyduino Library only supports precisely 44.1kHz sampling rate. It's hardwired into the usb descriptors and usb-comms

Does it have to be precisely 44.1 ksps?? I've seen that some of the classes in the Open Audio Library will also work at 48 ksps. I have successfully operated the receiver at 48 ksps.? I had to do
