Perhaps it is a regional thing but here we use it to describe the weather at the time the antenna is erected. In other words, the worse the weather when you install the antenna, the better it works.
It was cold and raining when I placed the tx. near my mailbox so maybe that is why it worked so well. I put the 12V battery, doppler unit, transmitter, and antenna in a plastic storage bin for this test. Seems the 10.25 GHz. and 930 MHz. signals go right through the plastic, though for the final assembly I am looking for something more elegant for packaging..
I am using the Linx receiver evaluation board presently for these tests and connected the audio output to an amplifier/speaker that I had built years ago for such purposes. The LM386 amplifier IC provides plenty of gain and output volume with only a few outboard parts. I don’t know if you will need amplification if you are using an earphone but thought I would mention this in case you do.
