Apologies for the second reply, to add: These come in lengths from 24 inches to 72 inches. All are built the same and are easily shortened as noted below. PS2408 PS3612 PS4816 PS6020 PS7224 The first
I realize this won't help but I have a similar noise. Mine is about 24 kHz wide and drifts up/down considerably more than yours. The drift seems related to outside temperature. Here's the real kicker
The first night they were on, K9W peaked 599 and a bit over here in central Maine around 0800z. Amazing! They were very readable for hours, but that was the peak. There was a secondary, much weaker p
