Good morning,
I was chatting with a friend about his experimentation with amateur satellites and have been pondering if his setup is "safe" for his radio. He is running an FT-847 through a duplexer (diplexer if you want to be pedantic) and into a dual-band vertical base antenna on his roof. Definitely not an ideal setup, but meant to be temporary until time and better weather allow. He has managed to make some FM contacts on AO-92 with it.
My concern is him using a duplexer in this manner while running full duplex. I suppose this is similar to what people must do if using an Elk antenna. I just worry about there being enough isolation between the ports and damaging his transceiver. Are there others using similar setups or is this something to avoid?
