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

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

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
