You're right, I forgot! Jack, W8TEE

V12 Boards Ver 50.2 SW All is working no freeze up or glitches since installing ferrite sleeves on ribbon cable. However if I install the audio hat it never finishes boot up before program stops with

Not its time to do it for the LPF too… and a section on winding that line section transformer and how to make the Power and SWR measurement work. Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ

You are the one that wrote that section of the manual… so, yeah! I know, we have both slept… Dr. William J. Schmidt - K9HZ J68HZ 8P6HK ZF2HZ PJ4/K9HZ VP5/K9HZ PJ2/K9HZ VP2EHZ Owner - Operator Big

Nice. Very complete. Is the term "stacked" explained in the manual? Jack, W8TEE

I just put this together today and added it to the back of the Assembly Manual. Makes it easier to see everything in one place. The next thing I’ll make and add is a test sheet for measured vs

I made up my own table. I just put one turn around the core, marked it with a sharpie. Then measured it. Then made up a spreadsheet, adding 2 inches to each length for pigtails. It came out pretty

Justin's manual has a similar table in it, but not the wire lengths. Because the BPF's use the smaller wire, the wire length in Kit and Parts should be very close to what you need. For example, L091

Jack Is there a similar sheet for BPF's LPF sheet is working out great Tim W4YN

Hi Jack I had a look at the file posted on 7/15/21 but its the same file as I already have downloaded. AT.h has no reference to "struct grafix" I can't see it mentioned anywhere in the code. Anyway I

I have not done all the bands but those match closely with what I have done. I also do not see much change messing around with turns spacing. On to LPF's to see how they come out. Tnx for all the work

I’ve made these changes to the assembly manual and the BOM for the BPF… Looks very good. The loss looks like about 3db maximum and that is easily made up by the RF amp in the front end. Also, that

These are great, Oliver. If it's okay with you, could you send me the hi-rez versions of the graphs? Al and I would like to include them in the book. BTW, I tweaked the toroids in the LPF board to

All: The final version of the code is about to be released by Al and I and we are turning it over to Oliver to care for it in the future. There are coding style differences that some people will

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
