Yaesu FT-991a Review Overview Demonstration HF/VHF/UHF/C4FM



What an awesome radio by Yaesu. The FT-991a is basically everything you could want in a complete rig. HF/6m/VHF/UHF/C4FM all mode, USB built in sound card and CAT control.

Check out this video to learn more.

FT-991 The Final Analysis

The final analysis of the ill-fated FT-991. But wait, is there a golden lining? Can you turn their mistake into a benefit for you?

FT-991 The Final Analysis

Yaesu FT-991 vs FT-991A why buy

I am wondering if the FT-991A is worth the extra 600.00 over the FT-991. I believe that there were some quality issues with the FT-991, but Yaesu corrected the issues with units manufactured in 2016. 

I am open to other radios that are similar. I want 160-10 HF, UHF/VHF. and 6 meters including FM.

I believe Yaesu is the only one that has the complete package in the price range of $1500 and under.

FT-991 Weak HF Receive - Receiver fault

Bugger me, the dam think blew again, I was in the WPX contect with my FTdx3000 with the amp and the FT-991A was on 40m. I noticed that in IPO mode on the 991A nothing heard. Lucky I had bought 50 of those little 150 ohm surface mount resistors.

Pulled the bottom off the 991A and found R1005 just next to RL1001. The resistor had broken in two and the cct board was burnt where is sits. Its not worth trying to solder the bloody thing in there as its too small. I tacked a small piece of wire onto the relay pad where one side of the 150 ohm resistor connects and a small piece of wire onto the terminal of J1001. The ends of these two wires sat above the board a little and I soldered one side of the new 150 ohm resistor to one wire, bent the other wire over to touch the other side of the resistor and soldered it.

FT-991 Weak HF Receive

I seem to have a big drop in sensitivity on all HF bands.  It has been a superb receiver for the past year.  Transmit is normal.

On a strong signal with ATT off and IPO the S- meter is at 0.  The spectrum display is near the bottom line.  The same signal with ATT off and AMP1 is S9+5dB and the spectrum display is above the first bar.   With ATT off and AMP2 the S-meter reads about S9+15dB and the spectrum display is on the second (middle) line.    The difference between IPO and AMP1 is an almost inaudible signal to S9+.

A signal that is S-9 on my FT-897D (with that rigs ATT and IPO both off) is barely S9 on the FT-991 with ATT off and AMP2 on and at S0 with no amps (IPO). With the amps off it is S zero.  VHF/UHF  is normal.  Looks like I have a receiver problem.

Back to Yaesu for repair???

Yaesu FT-991 AM Issue Resolution

Yaesu FT-991 AM Issue Resolution

Glenn/WA3LAB found the fix below on the net to resolve the issue with the Yaesu FT-991 in AM mode. The techs at Yaesu they said they’re aware of it, but Yaesu has not put out a bulletin on it.

Both Glenn & I have followed this procedure and it appears to work. I wouldn’t want it put out there without letting people know that they should proceed with care, and not to change anything else unless they really know what they’re doing. Since there’s not many people running AM anymore most people have no idea there’s a problem.

(Warning: once you put the radio into the service mode you can really screw things up, so do this at your own risk.)

FT-991 vs IC-7000 Review summary


About the IC-7000 verse the FT-991.... The 991 is a better radio.  You will be much happier with the FT-991... I had the IC-7000 for a while also...I do too many trades

There is NO perfect radio... The ATU in the 991 is better then nothing, but for a field radio is it a joke...It is only 3:1. It should have been at least 10:1.  IMHO... But if you have a antenna that is running a higher SWR on one end of the band and is still in the 3:1 it works..I have, and I highly recommend, the MFJ-939Y ATU..32:1 and zippy fast. The combination of that ATU and the FT-991 really does make for field radio or home one.

Yes, some idiot at Yeasu cut the FM radio off again. Damn stupid. Another funny is no real VFO B.  They do sneaky for splits. Works OK, but I still like a real VFO B sometimes. 

The touch screen does make getting around easier. A few functions are in the menu, but not hard to get around. Typical of Yaesu, a huge menu with a most default features that will never be used. Not sure why they don't just hide them and leave useful ones like ICOM

So would I recommend he radio over the IC-7000...Yes
