I turned it on today and it started to fade as it warmed up i switched to ssb and back to get the rec to come back that works sometimes. i did notice when it came back xtal rec. worked but when i switch to the man rec. its not working but if it cools all the way down both will work for awhile. i wiggle the v400 but there is no pop  or static. i noticed some popping in the man mode sometimes when it stops working. also it will stop rec. immediately when i unkey sometimes. the vfo transmits in manual but it would not transmit in manual mode when the man. rec. is out
