A basic method of transmitting in the frequency range 1.8-55.999 Mhz, 137-163.999Mhz, 420-469.999Mhz, with a European version FT991. All the info on this video is for information only, acting on the info is entirely the responsibility of the individual.
As a couple others have got FLDIGI to work with this write up I want to point out something very interesting.
If you are having real problems please UNINSTALL the ALL COM PORTS (hidden ones too) and there is a check YES UNINSTALL DRIVERS in the uninstall question.
REBOOT then install the YAESU USB drivers from the YAESU FT-991 files section.
Then restart FLDIGI and check the options below.
Settings for FT-991 and FLDIGI doing data-fm on 2m
I have the August 25th Firmware installed. I held in fast&lock as I powered on to reset all to factory defaults and then...
Menu settings in FT-991.
1/. All set to default (which show as blue colour when viewed on the screen of ft-991 as I scroll though) with the exception of...
menu 031 = 38400bps
menu 033 = disable
menu 077 = USB
3/. Choose DATA-FM mode.
4/. I was on 144.625 as I did tests today. (UK Band Plan - May be used for Emergency Communications and Community Events - which is why I am testing all this.)
Computer / FLdigi settings
I am using Windows 8.1 on a Lenovo Yoga 2
I installed the USB drivers from Yaesu from file called CP210x_VCP_Windows.zip
Then I connected the USB cable from radio to the USB socket next to power socket on laptop.
Device manager show COM4 as enhanced port and COM3 as standard port.
The New FT-991A – HF/50/144/430 MHz All-Mode “Field Gear” Transceiver – Coming October 2016
The FT-991A is the next-generation of the widely popular FT-991. Like its predecessor, the FT-991A is creatively designed to fit into a very compact (W9.0″ xH3.2″ x D9.3″) rugged case and will deliver up to 100 Watts solid output power (50 Watts on 144/430MHz) on SSB, CW, AM, FM, Packet and C4FM Digital on the popular HF/50/144/430MHzBands.
Coming Soon will be an optional FT-991 Hardware Upgrade Program that will upgrade the original FT-991 currently owned by users to include the new Dynamic Real-Time Spectrum Scope and Multi-Colour Waterfall Display. More Details Coming Soon.
As an example you can work in DigiModes using the latest free version of HamRadio Deluxe Suite (220.127.116.11) with the new Yaesu FT-991 (which is not supported in that version of the application) using the Yaesu FT-950 model in HRD. Without this application, you will not be able to set or read the frequency from the radio as the number of digits used to represent the frequency is higher for FT-991 (as it covers VHF and UHF bands too) making this application almost useless for the new transceiver.
FT-991 MARS MODYaesu FT-991 Frequency Expansion Information
- Model: FT-991

Use of any Amateur Radio product outside of the Amateur band is at the users own risk, and no guarantee of compliance with specifications outside the Amateur bands is expressed or implied. The Limited Warranty does not cover damage caused by any attempt to modify an apparatus for out-of-Amateur-band operation, nor does the Limited Warranty cover damage to components that may result from out-of-Amateur-band use.
Remove the bottom cover. On the CNTL-UNIT, place a solder bridge across the pads at JP3003, expanded transmission will be engaged. See the images below for location details.
Make a note of all your Menu settings, so you can re-load them quickly, then do a hard CPU reset in order to save the new frequency range. To do this, turn the transceiver off, then press and hold in the [FAST] and [LOCK] keys; hold them in while turning the radio back on. When the radio comes on, you may release these two keys.
FT-991 Expand TX ( MARS Modification )
Recent (and not-so-recent) posts have revealed underlying anxieties, especially among our newly-licensed friends, concerning firmware updates. Because of the benefits, enhancements, and technical improvements inherent in each update revision, there should NEVER be a question as to whether or not one should do a factory-released update to one's radio, regardless of manufacturer. Nor should there ever be a worry about "biting the bullet" or "messing things up." If one follows the instructions, one will always succeed provided common sense is applied. We all had to do it the first-time, sometime.
As to the common sense part of it . . .
1) Disconnect every single cable to the radio being updated except the power cord. Do not update using battery power.
2) In keeping with what most manufacturers recommend, be sure the radio is OFF when disconnecting/reconnecting cables.
3) Be absolutely sure the update cable is functional and of high quality. If you're a cheap-by-nature guy, you receive no sympathy from me for cheap results.
4) Understand completely the update instructions before you start. An update is not a tutorial.
5) If there is a UTILITY involved, be sure it is the latest version.
