Kenwood TS-2000 HF/VHF/UHF All Mode Multi-Bander (Sold)

Shown just after completing LED Display Modification:

YouTube Link to short video showing new LEDs

      

 

LED Display Kit - convert your TS-2000 from bulbs to solid state LEDs!

-current draw only 60 mA (bulbs 350 mA total)

-the LEDs will not burn out and provide a whiter light 

 

Why would anyone want to replace burnt out bulbs with OEM bulbs???

 

Kit (6 LEDs, 3 smd resistors, solder, solder wick)..... $30.00 (includes USPS first class

shipping USA). Specify white or yellow (original color)..

   1- SSB
      -Includes 2nd stage XFil Mod for flatter SSB Filter Response
      -Mod to improve IMD for PSK31 transmissions
      -10db RF mod to increase gain ("Improving the performance of the KSB2" - KI6WX)
      -20 turn Pot for carrier balance adjustment

   2- Noise Blanker
      -latest updated pcb  

   3- 160 Meter

   4- KPA100
      -Min 105 watts on all bands.
      -Improved swr/power accuracy even with KPA100 bypassed!

    5 - Astatic 575-M6 Hand Held Microphone 

   6- As of May 8, 2003: - Transceiver updated with all mods, and filters tuned 

       using Spectrogram.    

-Most IC's are installed into high quality sockets for easy removal.
-Used Kester "no clean" Silver Solder. Flux removed from most of the PCB's.
-Crystals are grounded as low as possible to the pcbs.
-Installed K2 Temperature Compensated PLL Reference Upgrade (May '03).  Picture of modification is shown below.....
