Any hole that is the size of a dime or larger will let mice in.
Stainless steel wool and the expanding foam that they sell
in a spray can at Home Depot is your friend.
Just stuff the stainless steel wool into the hole and lock
it in place with a squirt of the foam.

Use a mix of bleach and water (10% bleach) to clean all surfaces

the floor area around your radio so its wet, let it dry and then
sweep it. I would use some type of decon or the sticky traps

$32 is a pretty good price,
Is your control a receive only, or is it a UHF control repeater?
I've seen a 2m antenna used to feed both a 2m receiver and
a UHF receiver. After all, the third harmonic of 147 MHz is
441 mhz.

yell a FOUR into the mic with my lips
just a 1/4 inch off the mic grille.
And it's instinctive for the people in a

Well, item 105 is a VHF MTR2000 repeater. Think that might be

Hello,
Was Wondering if anyone had a link to a site that had samples of
talk thru Repeater traffic that would be considered good quality audio ?
Maybe i am expecting too much but any of the ones around here that i
have heard seem either Muffled or very Shrill,
Recently the FCC busted a local jammer and when his residence
was searched they found a treasure trove. There are over 200 pieces
of equipment involved including laptops, desktops, over 120 handhelds
and several repeaters. And broadcast equipment including a
