I have owned my FT-1500 for 19 years and never had a problem. Never been opened either, I have only had problem with the mic cord. I replaced the cord times because Yaesu uses very cheap rubber type coating. This is the ONLY downfall about the radio, but not the radio itself. I will use this radio till it dies. I personally never had a better 2 meter radio yet. I have contacted Yaesu about the mic cord and are aware of the problem....Well Yaesu fix it then!...If you are aware the don't keep manufacturing a cord that keeps frailing apart after only about 1 to 1 1/2 years of moderate use....This same cord is also used on other Yaesu models.....But overall I give the "radio" a 5 star rating!
Bought mine about a year after they came out and set it up for a 24/7 365 packet radio. About ten years ago I switched it to my APRS radio. It a real Energizer Bunny of a radio. It runs and runs and........ Wish all my radio equipment ran as well! I bought this new and paid 135.00 for it in 1992 IIRC and would not sell it for 175.00
I have owned the FT-1500m 2M rig for almost ten years now. Never had a problem with this radio and have even used it with FLDIGI for digital communications. The data port on the back of this radio worked great. It is very nice to be able to use voice and digital at the same time.
Great radio. Don't be afraid to buy a used one. Having said that....buyer beware.
