Dave, A couple of years ago, I set up a TKR-750K1 repeater for a local Amateur Radio club. The club bought the repeater without realizing that the K1 version is for 146-174 MHz, while the K2 version is for 136-150 MHz. This was a moot point, since the repeater pair was at 147 MHz. The K1 version does not perform well in the 144-146 MHz portion of the 2m band.
The repeater comes set up for a 3 MHz segment in the middle of its range, so the receiver must be retuned for optimum sensitivity on the desired receive frequency. Coils L2, L3, L5, L6, and L7 should be peaked for maximum sensitivity on your receive frequency at 12 dB SINAD, rather than stagger-tuned as the service manual suggests. If you haven't already done so, get the service manual B51-8556-10. It's available from Pacific Coast Parts for about $25. While you have the radio open, you should set the jumpers for backup battery charging and/or fan operation as you wish. Due to a computer crash, I lost my copy of the TKR-750 programming file and do not have a data file to send to you. However, I do recall that the software has many sub-menus that are not readily apparent but are crucial to interfacing with external equipment. It is important to disable many of the default functions in the native controller, when an external controller is used. Otherwise, the internal Morse identifier will compete with an outboard identifier. The software documentation is not very helpful in understanding the extensive capabilities of the internal controller. 73, Eric Lemmon WB6FLY -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Dave Compton Sent: Saturday, June 03, 2006 7:34 PM To: Repeater-Builder@yahoogroups.com Subject: [Repeater-Builder] Kenwood TKR-750K2 We are in the process of replacing our repeater with a Kenwood TKR- 750K2. The repeater is being tuned by a local short wave shop. I am trying to learn the software without having the TKR-750 to experiment with. I think I understand the software, but would like to see if anyone will share a programmed KPG-91D, FPU Data File, so I can see what a programmed file looks like. Yahoo! Groups Links Yahoo!
