Bruce, I have a 146.04/64 repeater and for years have noticed weak signals roaming in the bottom part of 146. I had thought it was from cable, but have not been able to verify or locate.
A local 146.67 repeater has the most server problem with a weak signal opening its receiver often (it is not toned). 73, ron, n9ee/r >From: lpcoates <[EMAIL PROTECTED]> >Date: 2007/11/09 Fri PM 11:01:32 CST >To: [email protected] >Subject: [Repeater-Builder] Possible interference on 146.160 > >Hi > >Our radio club has a portable repeater on 146.760 (-).
