I see from the manual that the TX & RX CTCSS frequency settings are separate. I'm wondering if this HT can really run "split tone" (encode & decode separate CTCSS freqs.). Simply having separate settings is by no means an indication that it can, since my Kenwood TM-G707 has separate settings

Chris, I plugged your frequency separation and power level into CommShop, and assumed a receiver sensitivity of 0.3 microvolts. The program responded that at least 77 dB of isolation is needed for zero desense- which is the obvious goal of any repeater builder. CommShop calculated that 77 dB of

Chris, There aren't many ways around the laws of physics. If you can't get adequate physical separation, and can't afford a duplexer...perhaps you just can't afford to operate a repeater. Can you gather enough interested users, and get everyone to chip in for a duplexer? If not, maybe your loc

Thank you for your response. The problem is that the repeater is located on top of a building and the tower on that building is only about 20 feet tall. We can move the two antennas apart horizontally, but only 20 feet vertically. Duplexers are way too expensive and hard to find for the 200
