Problem with a Kenwood TS 2000 Amateur Radio Transceiver

Fault description: About 2 years ago, the rig started off by randomly turning itself OFF any time from 2 hours after initial power on, as time progressed the fault became more frequent and time to switch-off dropped down to less than 5 minutes recently. And until recently I could switch the rig back on, after waiting a minute or two and it would often perform OK.

However; once the self switch off time progressed down to less than 3 to 5 minutes as noted above, the rig would refuse to operate correctly, in that it would come back on, on a different ban or a memory frequency, or, on the alternative VFO, (that is if it were initially on VFO A , when switched back on it would come back on VFO B). I have checked the Lithium memory support battery, it is OK at 3.1 Volts.

The rig had also started having difficulties with the Processor in & out gain settings and mike gain settings not being stable & repeatable! I suspect all part of the same problem. It (the rig) has never been fiddled with at all just used as is out of the box, although on SSB it never made better than 50 Watts out this however never was a worry to me!

73s I have heard of similar problems and some were heating related. the best is to check if your rig is heating up causing it to switch off and lose memory when switched back on. I have a buddy who had an unusual experience where he actually dropped frequencies so low that he could pick up ordinary radio frequency and also go into bands like 27mhz and 25mhz. But once switched off, the rig worked normal again. If you are experiencing heat problems then i suggest you put in a fan and remove all dust from inside the rig. You could probably also be having problems with power supply either internal or external. If all else fails, refer to a good repair shop this type of radios are very sensitive.

I have a KENWOOD TS-940SAT HF Transceiver that powers up with the TX indicator on, no power output and no receive.

Very little information about the situation of the transceiver is provided, it might be a complex one. The Kenwood TS-940SAT features a built-in automatic antenna tuner covers the amateur bands 160 through 10 meters. It is advisable for you to reinstall the transceiver and follow the right set up step to see if it works out eventually.

Transceiver signal interference

The FT-840 uses a die-cast RF power amp with thermally switched fan to ensure full power output (up to 100 watts). The digitally synthesized local signals ensure clean, low-noise transmitter output on all HF amateur band. There might be no AC line interference. it has strong Rf output. any AC line intersect does not affect its radio performance. Check and adjust RF power so to maintain proper output. some times more RF power generated at the output may cause interference. adjust Rf power..Even some unfiltered Noise getting the other end of the end may calso cause interference. Check for any Ripple voltages present at the output. Contact authorised service station for further Rectification. thank you shanth

Is the Kenwood TS680S a solid state transceiver?

solid state means transistors or ics but no tubes, if it has tubes it will have air holes in the case where you can see the tubes light up when it is on.Im pretty sure its a solid state rig unless it is really old as most are now solid states and have been for years.
