I'm curious what others in the US are seeing with orders from the usual Chinese suppliers.? I placed an order 1FEB for a bunch of little things from Aliexpress.? Everything has been sitting in

Thank-you Bill, I'm working through the build, and would like to ask; Does anyone have some guidance on a good target input drive power to configure the input pad for? I have 2 K9HZ kits and I plan

Huh.... I also use a separate data server (with a hot spare... dual connections to drives that are mirrored) using Samba to backup all of my files (for my business)... and our 96TB video server in the

Bill, Did you get my note about changes to the component values for the SSB Exciter chain on the RF board? If not , I will re-send it. These changes enable the flat response and lower adjacent

A great thing about the LT3045 is that you can parallel them for higher current and even lower noise (with careful PCB layout). John Bennett AE0AM

Yep. I can get then for the same price here but I must order them for future delivery… Yeah. Make some small boards and… Fanny and Bob are both in the house! Dr. William J. Schmidt -

and in 1K lots they cost $3.37 each https://www.analog.com/en/products/lt3045.html 20 mins with a PCB Design package and Fannys your Aunt !
