Can a Kenwood TS-50 be used as a tuner?
Accurate tuning, even at band edges, is initiated simply by pressing the AT TUNE key on the TS-50S. Band data is transferred to the tuner, so there is no need to operate the AT-50 directly and it can be installed in an automobile trunk.
Why is the 5V line on my TS50 not working?
Bad contact LCD Assy for 5V line to R9, R10 and IC5. Power on the TS50 and check voltage at R9/R10. If voltage is 0V, but display readout is active, the reason might be as discribed. Measurement to fix it:
Can a TS-50 be connected to a PC?
Small home made interface, in SMD technology, on the PCB 2×3 cm,integrate with TS-50S on the lower side of its PCB. The connecting line with PC can be home made. This can be done by specialists which can achieve an cheap solution. The most convenient solution is mentioned under 2.
Where is the Accy fuse on a Kenwood TS-50?
Attempting to tune the AT-50 when it is connected to an antenna with a relatively high SWR value might cause the ACCY fuse to open in the TS-50S. This can be correct by Locate X53-3470-00 D/4 (It is attached to the top left side of the chassis with the foil side up) The receiver can overload a bit easier than many larger radios. Dr.

What’s the problem with the Kenwood TS50 radio?
Modifications for the Kenwood TS-50 A page with Mods for various Kenwood amatuer radios Modifications for the Kenwood TS-50 TS50 FIX: LCD display dark Problem: No display illumination, LEDs On Air, AT TUNE no function The menu item 2 has no effect, display keeps always dark. All other functions normal. Possible reason:
