Notes on using the program


These are notes on using the program and how the FT-450 operates. If you have a tip to pass on to others please let me know and I will include it here.

The program uses only those CAT commands that are documented in the CAT operation Reference.

Whilst the radio supports memory names there are no CAT commands to enable you to read or write the name. Yaesu have been asked if they would add this in a future firmware release and I am awaiting a response.

The program only writes a memory if it is different to that already in the radio. This preserves any manual labelling that may have been done and speeds up the write process.

When writing to the radio if it is in Memory mode then you will hear relay chattering if the frequencies hop about a lot. This can be minimised by keeping the memories in ascending frequency or writing when the radio is in VFO mode.

There is no CAT command to erase a memory. To clear all memories hold in the V/M button when powering on the radio. You will be left with memory 1 on 7 MHz. Then write your desired memories to the radio.

Import/Export of files in other than FTBasic format is not provided. My other software can export in this format if you wish to transfer memories.

The shading in the memory grid highlights the boundaries (every 50 memories) of the memory grouping when this option is set in the radio.

When you start a read from the radio the memory grid is cleared. If you cancel the read you are left with an empty grid which cannot be edited. Either read from the radio or read a file from disk to permit editing of the memories.

The program tries to determine the radio's current baud rate and change it to 38400. It initially expects RTS to be on in the radio but an option on the Settings menu can be ticked to run with RTS off. If you are unable to successfully talk to the radio change the radio's CAT speed to 38400, ensure the RTS state in the radio matches the state in the program and retry.

Reading and writing the radio's settings is a future objective.
