Thought I'd drop you a line regarding my FT-920. You can put it in your user comments section if you like.
I bought my FT-920 (s/n 7F020254) at the Ham-Com convention in Arlington, TX (between Dallas & Ft. Worth) during the first week of June. The only problem I've identified so far, aside from incorrect information in the manual in a few areas, is with the Noise Blanker.
I sent the unit to Yaesu for modification and just got it back on Thursday (9/11). In the limited amount of time I've played with it since it came back, it appears that the NB no longer works at all. It used to work great, except for the trash it threw into the audio. But I'm still investigating -- perhaps the "right" kind of noise hasn't been present during my evaluation.
I agree with others who have said that the SSB filter is too wide (a side note: the slope tuning on my Kenwood TS-850 is more effective with it's standard width SSB filter than the 920's DSP is on it's standard SSB filter). The 920 should have had a slot for a narrow SSB filter.
Otherwise, I think it's a great rig, though I'm still eyeing the FT-1000MP! Oh, if I were only rich.

Back in September (when I was still KC5OA) I sent you my comments on my
FT-920. The following is an update to those comments:
As I mentioned in my previous comments, the Noise Blanker no longer
worked after I got my 920 back from Yaesu in September. They apparently
botched the mod because the NB no longer worked at all, and somehow was
affecting the operation of the AGC circuit. I finally got around to
sending the radio to them for a second attempt in mid-November and
received the radio back on December 5.
Now the NB works great! According to the service ticket, they "repaired
AGC circuit" (replacing three parts in the process), "re-aligned and
updated the NB circuit", and "complete test and aligned to specs". All
under warranty, of course. I am very pleased with Yaesu Service's work
After having a couple of more months of 920 use under my belt, I have a
couple of things I think should have been done differently or better on
Memory Management - When in memory mode, any change in mode, frequency,
antenna setting, etc., puts the radio in a state
called "M TUNE". Once in that mode, there is no
knob you can turn or button you can push to take
you to the next memory channel unless you press
the "VFO/MEM" button first. This is very annoying.
(on my TS-850, all you have to do is turn the
"M CH/VFO CH" knob to go to the next memory)
Band Edge Limits - The 920 has only ONE pair of programmable band
edge memories. Why? With 120 memories, surely
Yaesu could have easily dedicated ten of them
for this purpose, one for each band as in the
FT-1000MP, TS-850, etc. This scheme should
have been followed in the 920.
Narrow SSB Filter - I still think 920 could use the help of a narrower
SSB filter. I am looking forward to Mark's review
of the IRI 2.1 KHz SSB filter he's been talking about.
In my opinion, these are about the only areas in which this radio could
have been improved.
The 920 is a great radio (even better now that the NB works!) which I
plan to keep for a long time.

I thought you might want to post this somewhere in the FT-920 section of
your web page to see if anyone else may have had a similar problem.
Last Monday I discovered that my FT-920's antenna tuner would no longer
find a match on 20m. I also noticed that distinctive odor that burning
electronic components emit coming from the rig after about 15 - 20
seconds of the tuner searching for a match. Within a few more seconds,
the tuner shut down and the "High SWR" message appeared on the radio
My antenna is an R5 vertical which covers all bands from 20m thru 10m so
I immediately tried the tuner on the remaining bands. 17m, 15m, and 10m
were fine, but a match couldn't be achieved on 12m. So, both 20m and 12m
At this point I disconnected the 920 and tried two other HF rigs
equipped with automatic antenna tuners. Each radio was able to achieve a
match on all bands, 20m thru 10m. Obviously, the problem was in the 920.
I reconnected the 920 and operated the tuner on 20m several more times,
smelled that smell again, and the tuner still couldn't find a match.
After a few more tries, I let the radio sit, turned on but idle, for
several hours and late that evening tried one more time. The tuner
started out with high SWR showing but within a few seconds found a match
with no problem. I then went to 12m and found the tuner to now be
working properly on that band as well.
Everything has worked perfectly since. My guess is that a relay common
to both 20m and 12m was stuck and eventually decided to started working
again. I hope it's fixed itself -- this rig has been back to Yaesu twice
in 15 months (NB mod and a subsequent related problem) and I sure don't
want to have to send it again!

More follow up comments from Jim - 24 April 2000
Over the several months following my post about antenna tuner problems
with my FT-920, tuner problems kept popping up. In general, one day it
would decide not to tune on one or two bands while working fine on all
the others. The next day, all would work fine and might continue to do
so for a week or two. Then the problems with the tuner would start all
over again. My other rig (a Kenwood TS-850SAT) had no problems
whatsoever tuning the antenna. Bottom line was that I sent the rig back
to Yaesu in late 1998, to let them correct the problem. When I got the
rig back about six weeks later, it was accompanied by a note saying that
even with the longer than normal testing they put the radio through, no
problems were found with the tuner. To Yaesu's credit, they did this
work for free even though the original one year warranty had expired.
My FT-920 made three trips to Yaesu in the 15-18 months following its
purchase, with the first and third trips being busts (the botched NB
fix, and failure to find the tuner problem, respectively). After giving
Yaesu three shots at getting it "right" (four if you consider the
original production of the radio), I decided that I'd had enough and
sold it. Since then, I've acquired an Icom 756 and an Icom 775DSP (both
of them used) and would not trade either of them for another FT-920, due
to the less than satisfactory experience I had. However, I DO wish that
the Icoms had the 920's variable DSP bandwidth control! It was without a
doubt the best part of the 920.
