I don't seem to have the matching version. However, there is a file on the SCHR web site in the Files section that was posted on 7/15/21 that might be what you're looking for. Jack, W8TEE

Hey Dr. Bill 5V Display It was very flakey until I installed the Ferrites. Now it is bullet proof, can not make it hang up or freeze. V12 50.2 FW Audio is back working FB. Other versions of code had

Tim… is your display running on 3.3V or 5V? Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big Signal Ranch – K9ZC Staunton, Illinois Owner –

Hi Jack I am not sure its the correct file as it seems to relate to your earlier Antenna Analyzer project and not your more recent MicroController Projects Chapter 9 "100 Watt Antenna Tuner" The file

While I've slept since that book was written, I believe there is no L3 now. That was removed at some point during the editing of the book and we didn't bother renumbering the parts. As to L1, L2, and

Hi, I am looking at the ch8 programmable bench power supply schematic (p8-35) and BOM for same. My question: L1,2, 4 are shown on schematic. Is there an L3? In the BOM L1,2,4 are listed as "ferrite

I was having terrible issues with code randomly shutting down ie freezing. I had some ribbon cable ferrites that were split and I installed them on display and front panel ribbon cables. No more

Try it again. I just uploaded the file again. Jack, W8TEE

Hi Having the same issue as I can't find the source code? for Chapter 9 100W Antenna Tuner with Graphical SWR Analyzer. There is the folder

Yeah as I recall, the max output from the PCM5102 is something like 1-2V max... works ok for headphones but not quite there for a speaker. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ

Yeah that overload is a problem for a lot of SDRs because the front ends are wide open so even a loud AM station by your house could overload the front end and mixing circuits making you think there

You should get audio well before max volume. I had my V12 Main Board and RF board working with my V11 LPF. It worked fine, and I made QSOs with it. - Jerry, KF6VB

Bill I got some BPF in place and I indeed have audio in headphones, volume at max. Slow pulsing I had is gone. So the RX path is working FB. I still get some random freeze ups but at least all is

Oh yeah… now I remember… it’s the reason I have a large building full of Standard AM/FM broadcast transmitters. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ

ATSC uses 8VSB modulation.

Hey yall' I think I found a player in the noise problem (maybe one of several!).? I had a very marginal power return connection that I corrected, not sure how this thing even worked with this

Must have been an FM system? That process would not work very well for SSB… Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big Signal Ranch –

That test software just tests to determine if the hardware is there and functioning… not for receiving and transmitting signals… Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ

The system I worked on (ATSC) wasn't real time/continuous. The system took a snapshot of the RF, calculated then applied the corrections, then stopped. It could be set to run every X minutes, but

I see the sketch for testing board. I assume you load this into Teensy and plug BPF board into Boards Header? Not sure how I tell Teensy which band to activate. I am thinking? alternate maybe just
