Kenwood TH-F6A
I have a Kenwood TH-F6a triband handheld. I upgraded it with a Comet antenna when I bought it around 2007. It was my first ham radio purchase.
TH-F7E mod
6/30/18 Today I did the mod to extend transmit frequency range, so that I can use MURS bands. Now I can talk to my non-HAM spouse. Turns out this was easier than getting her licensed. I already have 2 ICOM IC-F11's set up for MURS, this gives me a total of 3 usable for unlicensed operation.
I followed the instructions found here: (Take your pick!)

Programming
I realized I want to program the scanner with repeater frequencies etc. and what a pain it is to do by hand, so I bought an RS232 programming cable (eBay for $14 including shipping).
Programming by hand (no computer available)
RTFM
Programming with a computer
http://w4zt.com/mods/thf6/mods.html
When I use the Mac, I use my generic USB-RS232 cable which shows up in Windows as a Prolific 2303 on COM7. (*Double check the Device Manager serial port to see if it's COM7 today.)
Don't forget the radio has to be set up to talk to the computer over the SP/MIC jack. By default it's set to talk to a Speaker/Mic. (Who would have thought.) User manual page 45.
- Push MNU
- Turn knob to select SP/MIC menu
- Select PC
- Push MNU to save or PTT to cancel
Set back to SP/MIC when done if you have a speaker/mic like I do.
Grig + hamlib
I just fired up grig ("apt-get install grig") for the first time. I am running on a Parallels VM called "Xubuntu Cinnamon" in my MacBookPro, Plover.
The command I used was: grig -m 219 -r /dev/ttyUSB0 In the radio I had to switch (MNU button) the setting from SP/Mic to PC to get it to use the SP/Mic jacks as a serial port.
I can see some settings but grig does not seem to do much.
At least I know the serial port is working and that Windows 7 + Kenwood MCP program is faulty. I can tune the radio. Have not been able to make it do anything useful.

This is a very interesting page on the TH-F6A; including several manuals and full schematics. http://www.hampedia.net/kenwood/th-f6a.php
