Kenwood TM-281A Adjustment Mode
Hi,
I am aware of a ham-radio NG. Unfortunately due to extremely low activity, I am posting this message here. Does anyone know the procedure to access the adjustment mode menu on my Kenwood 2M TM-281A transceiver? This is the menu that allows you to adjust the power lever, deviation, etc. Thank You in advance, John N3AOF PS, I was unable to locate a service manual on the internet, unless I pay for one. |

According to the following, it's similar to the previous TM-271A http://www.eham.net/ehamforum/smf/in...?topic=78074.0 And there is a 271A Yahoo users group covering the 281A. https://groups.yahoo.com/neo/groups/tm271a/info TM-271A service manual here http://www.repeater-builder.com/kenw...1a-svc-man.pdf -- Adrian C |

Unfortunately. the circuit board is much different than the TM-281A. In the TM-271A, there is a place on the PCB where you use a tweezers or other to short to "points", then turn on the power to enter adjustment mode.. Thanks again for your replies, John N3AOF |

People are still posting their ads where they don't belong, so unless you unless you actually post, you don't know that someone won't jump out of the woodwork and have an answer. Michael Hi Michael, Before I posted here, I downloaded all the headers in the ham-radio NG. I don't remember how many, but the total number was very small. However, you made a good point. I will also post there. John N3AOF |

This is the menu that allows you to adjust the power lever, deviation, etc. There's very little available for the TM-281a because the TM-271a is almost identical, except for a difference of 5 watts in Pout. Why Kenwood would need two almost identical models is an open question that was discussed in the Yahoo Kenwood group in the past. For adjustment mode, see instructions at: http://www.repeater-builder.com/kenwood/pdfs/tm-271a-adjustments.pdf Good luck. Hi Jeff, Although I downloaded the SM for the TM271A, I decided to use the link you provided. By golly, this is a different procedure than what I found in the SM! I will give that a try in a day or two after I finish some other projects I am working on. Again, Thanks, John N3AOF |

There's a Kenwood Yahoo group, I own a TS480SAT which has it's own Yahoo group - there may be one for your radio.

Again, Thanks, John N3AOF Hi Jeff, OOOPS, I took a quick look at that adjustment page via the link you provided, and jumped to the wrong conclusion. The front panel keys are used in making the adjustments, NOT for getting into adjustment mode. It is the same as the TM271A SM I downloaded. There is a BIG difference between the PCB in the TM271A and TM281A, and you have to access a certain place on the PCB in order to get the radio into "adjustment mode". Thanks for trying, John N3AOF |
