Re: [Repeater-Builder] Direct Strike Lightning Detector
Another old trick was to wire a flash bulb in shunt with about 20 feet of tower. W8AK In a message dated 4/27/2010 1:32:51 A.M.

I was thinking of paralleling a ground strap with a 10mA amp glass fuse. Maybe make the two connections to the ground stap 2 ft apart and use a fuse holder for fuse testing and replacement. I suspect the fuse would blow if any significant current went down the ground strap (or would the whole thing melt? I suppose either way I'd know!). Ideas? I live in an area that doesn't see a lot of lightning, I'm curious if the tower gets hit. Jesse

But Kevin is correct – check the BatLabs pages first to be absolutely certain. 73, Mark – N9WYS From: ST1Repeate ST1Re On Behalf Of Gmail - Home The answer is YES but you need to do a few things to get it there.

You need of course the Motorola programming software and interface, and when you want to program a new frequency, in your case 433Mhz, you have to hold the shift key down for the whole frequency, so it would be $##))).
