Hi:
I am going to build some HF bandpass filters, in the range 1Mhz to 54Mhz.
Since most standalone filters are fitted with SO-239 sockets, I would use
reasonable quality SMA to PL-259 male cables, and want an SO-239 calibration
socket set.
What are people using for this type of work on HF ham gear? At these low
frequencies, it seems like the amount of effort in the following document:
might be overkill? Have people found simpler (less work) methods to get
adequate results for tuning a bandpass filter at frequencies less than 50Mhz?
Cheers,
Neal
