900 MHz Mailing Lists and Web Sites

There are two 900 MHz lists and the first one listed below has 90% of the message traffic. Note that these are 900 MHz lists (for any radio, not just Kenwood) and do not take kindly to off-topic discussions. Personally, I'd subscribe to both. If you change your mind you can always unsubscribe later.   From the description text: "This listserv is used to further experimentation and utilization of the 902-928 MHz amateur radio spectrum using voice and data communications. Please limit your posts to information relating to these subjects ONLY. Want and For-Sale ads allowed. Do not post EBAY links. Do NOT list non-900 MHz applicable items."   From the description text: "For those interested in utilizing the 900 MHz amateur radio band. This group is here to discuss modification of commercial radio gear to amateur radio use, repeater construction for 900 MHz, and other related topics relating to the 900 MHz amateur radio band."
Alex Szuski KD6VPH has put together a web site oriented towards 900 MHz Kenwood radios. Check out

900 MHz Kenwood Radio Manuals and Info

Radios that have a model number ending in '0' are 800 MHz
and those ending in '1' are 900 MHz.
In other words, a TK-nn0 or TM-nn0 is for 800 MHz
while a TK-nn1 or TM-nn1 is for 900 MHz.
Additional information on 900 MHz radios and programming software can be found here.
Anybody have a step-by-step programming procedure for the 900 MHz TK-431 or 481 handheld?

TK-480/481 transceivers with a serial number of 30100001 or greater have a red triangle above the "W" in the KENWOOD logo label at the top of the front panel. You will also find the model name plate marked as "Ver 2.0" on the rear of the transceiver. You must use the KPG-49D to program Version 2.0 units; you cannot use the KPG-35D software with Version 2.0 radios. The KPG-36 cable is used with either software.

The TK-981 base mike is a KMC-9C. The mobile mike is a KMC-27A or B, the DTMF mobile mike is a KMC-28A (it's a 12-button mike). The "A" is significant as the KMC-28 has a different connector to the radio; the mike must be a KMC-28A.
The original TK-981 mobile mounting bracket is part number J29-0627-13, superceded by J29-0728-03, which will cost you about $7 (US). If the coax connector is damaged, you will probably have to replace the entire coax pigtail, which is part number E30-3031-25, which will cost you about $30. Either can be purchased from East Coast Transistor or Pacific Coast Parts.
