Sounds like you have a K-1 alright.
Firmware is kinda like BIOS.
Holding dowd PF-1 while powering up puts it into FIRMWARE program mode. The
number of decimals or periods showing on the display tell you what baud rate to
program the firmware in at. Now, do you have

I need to tune the VCO for my amateur frequency in the TKR-750. Does this
unit need to be hooked to the computer and set in some way before tuning? I
am at the very low end of what the repeater will program to at 147.060 and I
can't get the right voltage on the Test Point by tuning the capacitor.

It only says K-1. Goes from 146.000 to 174.000 or something near that. I am
confused at what the manual calls firmware. Is that like bios in a computer or
does it also take in programming the channels. Also the manual

Jeff,
You bring up an important point. While my previous post was about tuning
the receiver, it is always necessary to avoid either overloading,
overheating, or mismatching the PA in the TKR-x50 or in any other radio.
That's why I put at least a single

Hmmm-you might check effective sensitivity with the antenna connected,
