Did not yet try to optimize the delay. Will try The low frequency phase wobble reduces substantially if I use loadR=50.7 Could that be the actual impedance of the coax? Or is that the value where the

Someone else (forget who), showed to my satisfaction at least, that there was no need for anything beyond C0 for cal kits. He checked 3 kits I own * 85054B 18 GHz N * 85052B 26.5 GHz 3.5 mm * 85050B

If this works for you: .. then byte pairs for each pixel are out of order (wrong-endian) or struct.unpack() pairs bytes from two pixels (because wrong even/odd buffer prune), which should make color

Here's the same 1:1 choke being measured on the NanoVNA.

Hi Herb - "<76800H" must match 153600 == 320 * 240 * 2 == nanoVNA screen size in bytes Anything which breaks those "magic" numbers will also almost certainly break more in this script. Bit shifts must

No reason to dilute the other threads on this topic. This is the latest article on this subject from the people at Maury Microwave. Another worthwhile read. The link below takes you direct to the

Doing a manual optimization using openC0=300e-15 F openC1=-250e-24 F did result in an reduction of the amplitude variations (blue lines, see attached picture) Changing shortL0 seemed to have a similar

In an older post,(I now fail to find), Kurt explained it is possible to use, after calibration, a long high quality coax to test and improve the correction factors of the calibration standard. So here

Here's some AIM4170D results for 9 turns RG400 on 2xFT240-K toroids for comparison.

Keep an eye out for thickness - You've only got ~6mm to work with between the two PC boards. You may also need some double-sided tape or hot glue to hold the thing in place. -- -Chris

Hi Nan, SimSmith can be used to predict figure of merit difference between 52 and 43 11T on 2X 240 cores. K is similar to 52. Attached is a plot. Little difference above 14MHz. 43 somewhat improved
