- FT411.1
- Subject: FT411 MODIFICATION VIA COMPUTER
-
- I was unhappy with the FT-411's "3" mode because the frequency had
- to be entered starting with the 100 MHz digit, and the ARS function
- would not work. I now use it in the "2" (normal) mode with the
- following mod.
- I used the "clone" mode to dump the FT-411's ram to a computer. It's
- 9600 baud, 1 start bit, 1 stop bit, CMOS logic. 544 bytes are dumped
- when the up arrow is pressed. Starting with byte $211 are the upper
- and lower transmit and receive frequencies, stored in BCD. I changed
- these to the limits I wanted. My FT-411's upper PLL limit is 195.4
- MHz, so I used 195 MHz. The lower limit MUST remain set to 130 MHz
- (magic number) or the keyboard entry of frequencies will start with the
- 1 MHz digit .VS. the 10 MHz digit. To put the data back into ram, just
- press the down arrow and send the new 544 bytes to the FT-411. You
- could also just clone an H.T. that has the limits you want. You can
- not clone a mode "3" H.T. to a mode "2" H.T., however. The mode is
- contained in the first byte, which must match.
