Hi All:
I've had my FT-817 for 3 days now so am still experimenting with it. I have set the Pwr display to SWR (at the moment I'm more interested at what comes back than how much goes out.) As well, have a Bird 43.
On 2Meters I can get 4+ out and under 1.4 W. Back. On 6 meters anything I try to put on including the little ant. that comes with it show .6 forward & .4 forward. If I put on a dummy load I get 4.3 forward & nil back. Has anyone else measured backpower on the rubber-duckier?

Thanks

Using my 259B, I find that the antenna shows a resonance of 51.2 with
minimal "body counterpoise" and a min swr of about 2.5. With a good
tight grip on the 259, it shows about 1.1 at 50.8.

At 2 meters it was under 2 for the whole band, with resonance toward
the low end, with more body coupling lowering the min swr freq as well
as the min swr.

Both tests were done with the 6m tip in place.

Your mileage may vary.

My 6-meter performance with the rubber duck is poor, using the 817’s
internal VSWR meter it shows full scale, and power meter indicates the power
is being folded back.
Tests done with other 6-meter antennas commercial as well as home-brew work
OK. Called Yaesu about it and the tech said I was the first person that had
a problem.
Tech support said to return the rubber-duck for evaluation. I did not return
it. I have many other antennas that operate correctly, more hassle than it
is worth to ship it back to Yaesu. I still love the rig. Besides none of the
manufactures give you a good rubber-duck. I always get an aftermarket duck
or home-brew something. BTW Yaesu has had problems in the past with bad
rubber-ducks on at least one of their HTs.

I think I was a little negative on the 2m performance - with
reasonable "body counterpoise", it is less than 1.5 for about 144.4 to
147.6. Which ain't bad.

The 6m performance is what you would expect from an extremely short,
compound, handie talkie antenna. Again, I'm not complaining, this is
good old "EM Fields and Waves" - EE4xx. Physics always wins, and when
it doesn't, we missed something.

Ok:
Thanks to all who replied. Ducky still doesn't work but tightened
connector on whip and now get much more out than back.

I have had the same general observations, but last night I discovered
something new.

I was playing around with my new '817, and had the rig sitting on the
desk, with the "long" duckie connected with a right angle BNC
adaptor.
Suddenly, I noticed that the duck was exhibiting low SWR. After a
bit of testing, I realized that the SWR was low with my straight key
plugged in, but high with it disconnected. I was puzzled at first,
but then inspiration hit, and I realized that the key cable must just
happen to be the right length to form an effective counterpoise. I
grabbed the counterpoise off my homebrew 6m L-network tuner and
clipped it to the rig, disconnected the key, and whistled into the
mike. Low SWR (no bars at all)!

Regarding the effectiveness of the duckie for reception, I have the
following single observation. I am anxious to test this further as
soon as we have another 6m opening:

While I was in the middle of my SWR observations, the squelch broke
on
my FT-736 (10 watts on 6m to a 5/8 wavelength vertical), and I made a
couple of contacts into 5- and 0-land during a brief Es opening. I
also spent about ten minutes working a 7/mobile 0 who was about 5x1
to
me and who was receiving me about 2x1. After we completed our
contact, I went back to the '817, and realized that I could hear the
mobile station about as well on the '817 + rubber duckie sitting in
the basement as I could on the '736 + vertical. Now, as I say, this
is a single observation, and maybe my 6m feedline is full of water
(!), but I'm going to test this further. On the next 6m opening I'm
going to take the '817 + duckie + counterpoise out in the yard and
see
what happens. Meanwhile, I would like to encourage others to try to
do some 6m operating with the duckie + counterpoise and report your
results.

(I remember a Christmas Day openining a few years ago, standing
outside just before sunset with my IC-502, at about 7000 ft. MSL in
Idaho, near the Wyoming border. It was COLD, but I had no trouble
working into the midwest with three watts and the built-in whip.)

See ya on Field Day...

Many years ago myself and several Hams (KB4CRT,K9IJ,K4WSB,WB4IOA, and maybe a
couple of others who I can't remember)were on a boat trip in Tampa Bay when
KB4CRT heard the 6m band open to somewhere in South America. The rig was a
Mizzuro (not sure of the spelling) handheld about 100mw SSB to a rubber ducky.
All of us worked the South American station and exchanged 59 signal reports. I
guess that's why it's called the magic band!!!!!

Hi Julio,

6 meters is a great band, it has been my most favorite band for the last
21 years. My first rig was a Kachina 1 followed by a more modern Yaesu
FT-608R through the lastest in the FT-847 mobile and FT-817 backpack.

With a good E opening you can work almost anywhere with milliwatts.

However, I have still to work all 50 states, missing 6m and I am only
half way to DXCC on 6.

In 25 years + of hamming I NEVER operated 6m until I got my '817. It's
quickly
become my favorite band. I recently worked Fiji with the rig from central
Tokyo
using a groundless vertical on my 2nd floor balcony, getting a true S9
report.
I couldn't believe it and didn't believe it was for real until I got the
QSL card.

On my trip last weekend to Amami Oshima and Kakeroma islands (IOTA
AS-023), it was
6m that generated the majority of QSOs, despite hours of trying also on 10
through 40
with a variety of antennas.

I've concluded six is hamming's best kept secret and regret I didn't get
on the band years
earlier.

Thanks for th message Steve. Yes 6m is a great band, very exciting at times. I only need Alaska for WAS on 6m, bad part is I've need it as my last state for about 15 years. Alaska not heard in Florida very often. I'm hopping the FT-817 will at least alow me to listen more during the last stages of this cycle, and with any luck help me catch an opening to Alaska!!!

73's Julio

Julio, I plan to be in Alaska (Anchorage, Denali, Fairbanks) with my '817
in September. Will be happy to try a sked on 6m, hi hi.

I'm sure a sked would be a waste of your time, but with 6m you just never know. HI HI
