The three tables below were received as two anonymous emails in December of 2008. All we did was clean up the formatting and convert it into HTML for the web. Since we're not Kenwood geeks the Repeater-Builder staff can't take responsibility for the accuracy. Since a KPG-4 (with a 6 pin RJ-series plug) can be used in place of a KPG-46 (8-pin RJ-series plug) there are probably a bunch of errors in the cable specifications. There are a lot of unknowns as well, indicated by '?' in the tables.

If you can donate any information (including PDFs of any radio brochures, like the TK-255 below, or photos of the programmers or the programming cables) please send an email to Mike WA6ILQ at the email address below.

Likewise please let us know if you have any corrections or any additions to fill in some of the blanks below.
Kpg 56d Free Download1) The KPG-36 is a KPG-4 with a one-piece speaker mic plug instead of a RJ-connector. You can use a KPG-4 with a home-made adapter that consists of a RJ-jack, some wire, and a speaker-mic connector. See these photos of a KPG-36 connector front and rear. 2) The KPG-22 is similar to the KPG-4 but with a dual connector (1/8' mini and a 1/16' sub-mini headphone-style connectors) for the later handhelds. See this photo and this schematic of a KPG-22 cable. You can make an adapter cable that will ket you use your KPG-4 on the handhelds that use a KPG-22 very easily using two separate plugs - just use the plug connection info from the schematic. 3) Note that Kenwood numbers the pins backward from Ethernet. The KPG-4 and the KPG-46 are the exact same unit except for the RJ connector on the radio end of the cable. The KPG-4 has a 6-pin (RJ-11 / RJ-12-style) connector. The earlier KPG-46 has an 8-pin connector (RJ-45 style) and the center 6 pins are wired the same and the outer 2 pins are not used. If you are careful the 6-pin KPG-4 will work perfectly in the 8-pin mic jack. The plastic tab should only let you put the 6-pin plug into the middle of the 8-pin jack since pins 1 and 8 on the 8-pin jack aren't used for programming purposes. Look carefully at the 6-pin plug however, some have a thicker shoulder that will push pins 1 and 8 of the 8-pin jack up into the plastic body, bending and damaging the two pins. If you are going to build your own programming adapter you could copy one trick I saw - the person used a dual jack snap-in housing, mounted the perf-board inside, had a DB-9 pigtail coming out of one side, a connector for a 12vDC wall wart on the same side, and both 6-pin and 8-pin jacks snapped into the housing. The two jacks were wired so he could use a common 6-pin phone cable to connect to to the 6-pin radios, and a common ethernet patch cord for the 8-pin radios. Or you could build it with one connector, and build an adapter starting with a 6-pin RJ-12 jack wired to a stub of a common 8-pin RJ45 ethernet cable. See this schematic for a KPG-4 and KPG-46 cable. Or look here: Here's another one. If you are going to build your own programming adapter you will want to print both and study them. 4) Yes, conflicting information. It's what we received. We'd love to have any info that will resolve the conflicts.
