In order to test the filter I got via ebay, I just connected it outdoors, not really the best thing to do.
Today I went to the local "elektronica-boer" and got some connector adapters making it possible to move the filter indoors. I had to retain the filter before the extra indoor amplifier in order to avoid IMD problems, so a bit of extra adapters were necessary.
One day I will have to make a web page describing the whole thing, but that is for later.
Busy day tomorrow with non-radio stuff, so hope to get a bit more done today.
Another Blast from the Past -- Dino KL0S in the early 70s -- A Turner mic,
a Vibroplex, an HQ-100, a DC receiver, and a tech library.

*Dino: Yes the parallels are really eerie OM. There is that Turner mic.
I still have mine too, but I had to replace the element with an Electret.
Mine ...

That webpage would be a good one to have ;-)
