FT-950 UPDATES VERSIONS AND DIFFERENCES

MY RADIO CAME WITH 20.47 AND 1.13
MY SERIAL NUMBER  01 47 0044 (SIGNIFICANT DIGITS HIGHLIGHTED)

WARNING:
A BIG DEAL IS MADE OF RADIOS ABOVE 43 NOT USING OLD “EDSP” SOFTWARE THAT BEGINS WITH ANYTHING OTHER THAN 2X.XX
THE 1X.XX SOFTWARE IS NOT COMPATIBLE AND MAY CAUSE DAMAGE!

THIS INFO ONLY DEALS WITH THE USEABLE SECOND SET OF FIRMWARE FOR THE CPU THAT INSTALLS WITH THE BACK PANEL SWITCH METHOD.

I researched this information from the Yaesu Website. I decided NOT to install the updates that would have enabled the new Channel 3 on 60 meters. Also, the CW and Digital modes are legal on 60 meters, but you have to be careful in setting the frequency to center channel. I plan to use the radio with the original 20.47 and 1.13 software.

My radio is modified “transmit all frequencies”. I plan to enter the necessary channels into FT-950 normal memory channels. When I access them, I press dial lock to prevent the radio from entering VFO mode and transmitting off channel.

The modification software would defeat the use of bandwidth settings on AM. It also defeats the use of the mike processor in AM. I find this unacceptable. You may not. Really, the bandwidth and processing should be linked to the mode, and set once in menu, not constantly tweaking it. This goes for the power setting as well. The menu summaries provided elsewhere for mode specific menu optimization are an operator help, if you print them out and keep them handy.

Be sure to verify the following information for yourself on the Yaesu website before you perform any downloads to your radio. Your application may be different from mine. Also, verify the software download you attempt is compatible with your radio serial number – see caution above.  

V1.13 – 6/11/10 Includes all previous updates. NOTHING BAD.
	AGC If an AGC MENU SET AGC ITEM WAS CHANGED, THE AGC WOULD SOMETIMES TURN ON.
	KEYER Extraneous DOT memory eliminated during rapid keying when the dash output starts.
	CAT: Corrected the 1.5 KC shift when the CAT FA command is used to change the frequency on the 5 MC band
	SCOPE: right edge signal position on display fixed
	SCOPE: left edge signal is corrected when the frequency is changed on the display.
	Recommend operating PROC level within the 5 dB to 10 dB range.

V1.14 – 7/12/10 Improved to recall the nearest ATU memory at less than +/- 1% of the transmit frequency. NOTHING BAD

V1.15 – 9/9/10 When exiting the CTCSS tone setting procedure, no popping sound will be heard when pressing any buttons. NOTHING BAD.
