TS 2000 KENWOOD TRANCEIVER

I HAVE A KENWOOD TS 2000 AMATUER RADIO TRANSCEIVER WHICH I HAVE THE FEELING,HAS GONE SLIGHTLY DEAF ON RX.THE DEALER WHOM I PURCHASED IT FROM HAS TESTED IT AND RETURNED IT TO ME,QUOTE NOTHING WRONG WITH IT !! I HAVE COMPARED THE RX TO OTHER RADIO TRANSCEIVERS I OWN AND OPERATE AND THEY ARE MOST CERTAINLY MUCH MORE SENSITIVE ON RX !! ( I AM A FULLY LICENCED RADIO AMATUER )
THE TS 2000 UNDER WARRANTY,SO IS THIS A PROBLEM ANYONE CAN ASSIST ME WITH.IE:- HAS ANYONE THE SAME PROBLEM,IS THERE A CURE,OR IS IT DUE TO THE FACT THAT THE TS.2000 IS A"SHACK IN A BOX,A BLACK ONE AT THAT IT WOULD SEEM"

    Main Rx is about 20 dB worse NF than the Sub. Measured all bands 3.5 through 432 with 15.5 ENR source. Note I had done this when brand new and now it is ~ 20 dB worse also measured by 3 dB rise method with calibrated sig gen. I haven't opened it up yet - but appears to be at or after the 10.695 MHz Rx stage from looking at the service manual, as that is where the upper band front ends are mux'd in with the HF-50 MHz front end.

A lot of TS-2000 radios suffer from attanuated receive, it is caused by a design problem of the transceiver.
The cause is leakage within the 455KHz ceramic filters, the manufacturer states in its datasheet that coupling capacitors should be used and Kenwood,in its wisdom opted not to bother to fit the required capacitors.
The Toko filters are not easy to obtain and may attract a lengthy lead time.

I had a similar problem which turned out to be high resistance contacts on the K3 relay which switches the inbuilt antanna tuner in or out.Go into the menu Number 27 and toggle the antanna tuner on and off on receive.There should be no change in received signal level (assuming the tuner is tuned up on the frequency)On my unit the level was dropping up to 30 dB I Replaced the relay which cured the problem.

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.

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.

Problem with a Kenwood TS 2000 Amateur Radio Transceiver


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.

IP Assignment....


No, a tranceiver cannot be assigned an IP address. It just converts the signal between two types of lines (fiber, copper, etc.). This is mainly used for connecting together networking equipments such as switches or routers.

Depending on the type of interface you plotter have, you may need a device called a Print Server. This device has an IP address and allows a conventional printer signal to travel through an IP network. If your plotter is designed to be connected using a LPT (Parallel) cable, like old printers, you may look for the D-Link DP-301P+ or DP-300U.
