Kenwood TS-590 (ver.E) TX modification for 5MHz by Roar, LA4AMA

Kenwood TS-590 TX modification

The E version (Europe) has no TX on 5 MHz, but the K version (USA has 5 MHz TX between 5.250 MHz and 5.450 MHz. According to the service manual (page 120) the difference between E and K version is a jumper (R968) which is installed in E version but missing in the K version.

There are 2 possible TX extensions on the E version, either full TX (1.705 – 30 MHz) or just open up 5 MHz (cut the R968 jumper and make it into a K version).

Complete modification guide is here
