You wouldnt hear the sync buzz,your rx is tooooo narrow! I live with the
beast here,coming from a neighbors house who wont let me find or fix it.
It mixes with ANY vhf signal and sends it back at me every 10khz up and
down the band. I can get away from it if I offset either the rx or tx
freq by a few khz. OTOH,they cant watch cable anywhere near 2
meters....Now 70cm works good until a scanner pops up on the local pd
freq. LO=my input! What can ya do??? 73,Lee
