If a get only 1 bar on the internal SWR meter on the ft-817, how
accurate is this reading?

I use: ft-817 attached to balun (1:9) through a RG-58 coaxial cable.
then, attached to the balun, a normal electricity cable (about 25
meters). SWR on all bands: maximal 2 bars, mostly 1 or no bars at all.

I am not using any tuner, mind you!

Should I be worried?

Rene PD1ALD

Reading your question again, I realize now that you already have a
tuner. Usually, the standard "Pi" or "T" network tuner has a
connection point for a single wire, so I think you probably
already have everything that you need. Just attach your antenna wire,
and make an appropriate quarter-wave counterpoise. My counterpoise is
long enough for 40m operation, and has plugs in line so I can
disconnect sections and shorten it for 30-20-17-15-10, as needed. (I
still need to cut the wire and install a plug for the 12m length. The
'817 is my first rig with 17m and 12m, so I haven't gotten around to
this yet.)

My standard "in the field" antenna is a 50- to 75-foot length of wire
(15 to 20 meters long) with one end pulled up into a tree. I connect
the wire to my trusty old MFJ model 16010 L-network tuner, and connect
the tuner to the rig with a short piece of coax. I "ground" the tuner
with a quarter-wave counterpoise for whatever band I am working. At
home, I operate with the same tuner connected to a 250-foot (75 meter)
length of wire. I use a counterpoise for 40 through 10 meters, but
for 80 and 160, I just ground the tuner to everything available (other
rigs, coax shield for other antennas, etc.) For 6m, I have found that
I can also use the wire, but I have a homebrew L-network tuner which
has more appropriate L and C values than the one in the MFJ tuner.
For 160m, I have to open the tuner up and add a bit of capacitance in
parallel with the built-in air variable. (I don't recall how much,
maybe 100 or 200 pf?) For QRP work on 160m, I have found that a
couple of silver mica caps connected to alligator clips work just
fine.

Although I have only had my FT-817 a few days, I have already worked
into Europe and the South Pacific on 17m and 20m SSB with it using
this antenna. My Butternut HF6V blew down a couple of winters ago,
and I have not replaced it yet because this antenna works so well. (I
still have an HF2V that I use for 80 and 40 QRO.)

I recommend the L-network tuner + random wire + counterpoise as a very
easy solution to your question.

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...

Hi All:

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

I suppose there are many configurations that will work. But here is one that
I know works. I have a 15 meter dipole (approximately 23 feet overall
length) center fed with home made open wire line directly into my Z11 tuner.
No balun, I just soldered the open wire to a PL-259. It loads on all bands
from 40-10 (maybe 6, I haven't tried it). It doesn't seem to be too
efficient on 40 but it works quite well 20-10. It's only about 8 feet above
ground but I have worked all over Europe, South America and a couple of
Japanese contacts. No 599 signal reports, but solid contacts.

I like to create a randomwire antenna for use with my FT-817. I first
created a dipool antenna fed by a 50ohm coax. This was good enough to
make my previously announced "First Contact". I now have this rig of
my own, and also did buy an antenna tuner.

The questions is: What is the easiest and shortest Randomwire I
should create. How should it be fed and do I need to put in any
resistors or baluns.

Details: I don't have much space? I don't expect the length to exceed
15 meters. It does not have to be straight, so L-antenna is an
option. I don't mind loosing the 160 and 80 meter bands. I like to
have 6 - 40 meter band operational. I don't need outstanding
performance on transmit, but it must be able to send with it.

If you have any suggestions, and like to put graphics to explain, you
can mail me directly (pe3chi@...).

Another question: Anyone has any experience with sending on
Base/Mobile HF verticals?

Regards,
Marco

Nope, with the 20 meter Maldol mounted directly on the FT-817, I get 4 to 5
bars in on the SWR display and have been completely unable to adjust that or
make a contact with it. Mounting it on the Z11 tuner will give you a perfect
match and then it also works!

You could also look at RM products in Italy. They do CB (25-30Mhz)
amplifiers , but also VHF and UHF and some have HF capabilities.
Power from 30W-to 500 Watt with 1-7W input.
Look at model KL203 and KL351, but also KL300 offeres 3-30 MHZ
capability. The cost are really low for Europe (approx.50EUR) and
some modification or filtering could also improve linearity. At least
it is a good kit to start with.

P.S. I think Ramsey had an HF AMP kit (QAMP-20) which would have

been

perfect, but I don't think it exists anymore.

OE3MZC:
The reason for the SG237 Smartuner to start the tuning process again
might also be an old software in the EPROM of the 237! You can write
to SGC and ask for a new version that makes the tuner more stable or
you can use the SMARTLOCK feature.

I have found (the hard way) I need a separate power source for the
SGC237 Porta tuner. Running the SGC2020 and 237 from the same source
leads to problems when voltage dips on voice peaks. (From a 7 amp
Pyramid PS). When this occurs, the 237 loses tune and relays start
clattering. I figure a 7ah cell for the 237 and small, maybe 1.2ah

for

the tuner would be realistic.

Same thing happened to me about a month ago. But I didn't have any
power on uhf/vhf either. I sent it into yaesu service, and about 3
long weeks later, it came back. On the repair ticket, it said that
they replaced a FET and a resistor. I am assuming that this would be
the power FET.

However, now it works. I did have to correct the power supply

voltage

reading, because it displayed the voltage as being exactly 1 volt
higher. Weird.

I'm not sure what caused this all. The only thing that could have
failed in my case would have been my zm2 tuner, as I discovered an
intermittent contact later on. But still, the output should have
rolled off in that case, causing no damage. I don't know. I am just
really careful now.

Good Luck!

Hi Rene,

This may be a dumb question, but are you sure you have TX power

With

the

IMHO...
An excellent aftermarket accessory for the FT-817 would be a small
waterproof speaker-mic with a Heil mic element. The FT-817 speaker-mic
cord would end in both an RJ45 and a mini-phone connector.

The Vertex VX-1200 has an excellent waterproof speaker-mic with a mini
socket on it for an optional earphone. I certainly have found the
VX-1200 speaker-mic to be a very convenient device for hiking
(pedestrian mobile).

This is not worth an argument, so let me just say that my manual
shows the headphone/speaker connector as tip/sleeve and only one
channel is active if I plug stereo 'phones into the radio.

If you select headphones, as opposed to SPK on the little switch by the jack
you get mono in stereo headphones. Quite a clever trick

There's a gold-plated version, RS # 274-882, that may have superceded
the cheaper model.

Of course, I think this is all moot, since my radio doesn't require an
adapter,

Also, the original inquiry came from oh6bi, so any RS numbers may be
irrelevant for that person.

I've tried mine. Stereo phones work fine. Sound in both ears.
I just tried again with three different sets of stereo headphones.

Maybe it's a model change? Mine's serial # 1D250091.
Does your schematic show a mono jack or stereo?

Perhaps we could have input from others?

I have an old BM-5, which is
Heil's lightweight headset in a one-sided model, which I think is just
about perfect, except when wearing a helmet. They aren't, apparently,
made any more.

Negative, although only the new version of the BM-10 is
listed on the Heil website, they are making the BM-5 too.
Just took one off when I left the shack. :^) Very light and
convenient with excellent tx audio.
