I have an FT-101EX that I got as a backup radio. It is my third one of that series. I wish I kept the last one I sold in the 80s as it was in better shape and function than the current one. If you are worried about transmitting accidentally, just do not flip on the "heater/filiment" switch for the transmitting tubes. If you are wishing to resell them, perhaps you should make more effort to get ahold of the accessories and manuals that are missing now. Those add more value for sure. You can use it to SWL on hams or 10 Mhz WWV and any SW broadcasters nearby. But Yaesu made a somewhat identical general coverage SWL receiver called the FR-101, one version with analog tuning, and another with a green digital display. If you want a similiar SW receiver, you could trade someoone all that stuff for one of those. I have an FR-101 and matching speaker but it is also just a backup, I use it mainly with no antenna, and headphones, to monitor my transmit audio quality when making changes! http://www.foxtango.org
used to have alot of info and downloadable manuals for that stuff, and I suspect they still do. Nice gear, holding it's value if the condition is fine. Just that the tx tubes are big money now. The landliner is a good sounding extension speaker regardless of the phone patch just for show. Lots of them on ebay to gather ideas of pricing but condition dictates alot of that.
