[Kenwood] TS-950SD Transmit on Power Up - Solved

[Bob Farkaly]

My TS-950SD suddenly started transmitting within about one second of power 
up. After checking to make absolutely sure I wasn't causing this (PTT, 
keyer, etc.), I made local inquiries as well as on inquiry on the 
reflectors. There were great recommendations on the NIDXA, the local SDDXC 
as well as on the Kenwood reflector. Many thanks for the great assistance.

But my biggest thanks goes to LOU DE BEER, ND6W, on Coronado Island for 
diagnosing and fixing this problem. It seems the problem was indeed on the 
control board as others had indicated. Lou ordered a replacement from 
Kenwood, but the board and its components were no longer available. So he 
examined the board very closely using a high power magnifier and light 
source and found that the "feet" of two of the surface mount components were 
pulling away from the board under certain circumstances. Sort of like an 
intermittent connection. He used some heat and  was able to fix the 
intermittent connections. Now my TS-950SD is fully back in service thanks to 
Lou.

Oh and the price was right as well!

I can't say THANK YOU too loudly. Lou fixed my radio!
