noise on CW

mike newbold
 

Hello 817 ops,

I experience quite a bit of noise when operating in
the cw mode, especially when i install a good antenna.
Yaesu optional CW filter installed and seems to work,
Narrow button on, I have only found that limiting the
RF gain, and turning up the volume helps. Any one
else seem to have extra than normal noise. Other rigs
i use for comparison are probably in a higher price
range, FT-100, MP, but others are not: the sierra,
SST, DSW. Does the inrad cw filter offer any great
advantages?

I bet by now, a lot of you are NOT using the AA
Battery compartment. what a great place to install a
DSP unit( amongst other things). any one done that or
working on one?

817- one of my favorite radios
tnx 73

Re: MALDOL whip - SWR kinda crummy?

 

Anybody having trouble with getting these animals
to resonate after adding a counterpoise might try
adding a capacity hat over the coilmade with a couple
of stiff wires and aligator clips - I've found this
to be effective on several homemade whips I've fiddled
with over the last month - it's particularly easy to
work out if you're using an antenna analyzer, although a
2.5 meg shift to 20 meters might be a bit of stretch.....
I just tried that. Clipping a piece of stiff wire to the tip of the whip. I
did get it to resonate but it took 46 inches of wire and was mechanically
pretty flimsy - don't breathe hard it will fall over. I think the "Miracle
Whip" is looking better and better. The article in the July QST is quite
good.

Re: Fw: SSB Filter - Help!

Which brings me to another possible angle on the question whether
the
ClearSpeech unit or the SSB filter might be the better purchase?
The CS
unit will (obviously) only help on rx, while the filter may help
both in rx
as well in tx. So, while both might help to pick out stations you
might
have missed or given up on otherwise, the filter may help you to
present a
workable sig to listening stations.

Having said that, I don't mean to imply that it's likely going to
be that
clear-cut; the filter wouldn't be a magic bullet. But being able
to hear
another station does't help if they can't or won't come back to you.

Unrelated Q: how much extra current (if any) does the SSB filter
(or the CW
filter, for that matter) soak up?

Hi.
The current drain for any filter shuld be about the same,
as they are all selected by the same type of circuit (diode matrix).

The values for the resistors/capasitors around the filters are the
same.
So is shuld be possible to desolder the original ssb filter and make
connections to the optional ssb filter, and use the socket for
the cw filter.
I am still waiting for my cw filter to arrive. so i dont know if
there is physical space for both filters.
If i find space inside the 817 i will install both filters.

Gel Cel battery / Auto Cig Plug?

[email protected]
 

After going through far too many AA Duracells, I have broken down and
purchased what was called a Power Kit from www.PowerPortStore.com
(those folks who make the WorldPouch etc.) which is a 12 volt 2.3 amp
gel cel battery. As quickly as the Duracells were draining I found it
useful to attach a Cigarette lighter plug to the power cable that
came with my 817 so that I could use it in my vehicle as well as
utilize an AC power supply I have at home.

Anyway, I would like to attach that Cig Plug to the leads that come
off of the gel cel. that would enable me to use auto/ac-converted
power when available (perhaps even slow charge) and leave me
connected and using battery when it's not available (just need to
roll up and stash the cord...)

Will this damage the battery?

I've posed this question to the manufacturer and there has been no
response to date....

Re: MALDOL whip - SWR kinda crummy?

 

The curious thing about that is you would think that they would design them
to be a little low in frequency so that all you would have to do is push the
whip in a little to get it where you want it. But they make it high where
you can't do a darned thing about it other than add an external loading
device, or kludge up some kind of whip extension.

Kinda is not even close.

I tested some Maldol whips with an MFJ259B. At that time the 40, 20
and 10 meter versions were available from my local radio dealer.

The 10m is fine, and resonates at a little less than 29meg.

The 20m will not go under 16.5 mhz even with a counterpoise.

The 40m is similarly high.

The resonant points had reasonable SWRs, just too high in frequency in
the 40 and 20 cases.

I don't know how any of the other available bands work other than the
3 I tested.

If someone could find a way to extend the whip a couple feet in a way
that would be strong and light, they might work OK.

Found the same box in "Gander Mountain" (hunting, fishing, camping

the equipment. A chain discount store (Meijer's Thrifty Acres,
similar to Wal-Mart) had something called a "Sportsman's Dry Box",
which looks like an army surplus ammo box but is made of plastic.
This cost about $12 US. I then went to a craft store and bought a
2-inch thick sheet of stryrofoam, which I used to build up a liner
with recesses for the 817, ZM-2, and a 7-AH gell cell. I've posted
a
photo of my first rev. of the resulting outfit to the Carrying Case

paddle sits in also provides a path for sound from the speaker. The
total cost of the case and stryrofoam was about $10 US. 73!

Re: How accurate is the internal SWR meter?

Jason
 

Hello Rene,

I don't think you should be worried at all.

One bar on the SWR meter is most likely insignificant. My 817 sits
here on my desk, connected to a portable tuner with a built in SWR
meter. I'm using a 20m dipole. When the SWR measures decently low
(1.5 to 1 or less) the bars on the rig will fluctuate between 1 and 3
bars.

Sometimes when my external meter shows flat SWR, the bars on the rig
will read 2 or 3 bars, and when I adjust the tuning to get the bars
on the rig to disappear I find that the SWR on the external meter
increases. It's one of those balance acts between what the rig says,
what the external meter measures as SWR and what the external meter
measures as amount of power out.

I would say 1 or 2 bars on your rig is just fine. Even the supplied
whip for 144/440/50 gives you a few bars depending on frequency and
such. But, if you can get your hands on an external SWR meter that
will activate with just a couple of watts, it would be worth it just
for your peace of mind to check your antenna.

Enjoy,
Jason (NF6E)

If a get only 1 bar on the internal SWR meter on the ft-817, how

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?

Re: Monophones for 817 ?

 

Hi Listmembers,

On the FT-817, mono and stereo plugs and headphones work excellent.
No need to use any adapters.

MOD problem: attenuated RX

 

After an afternoon of FB operation on 6 m with the FT-817 I decide to
install the SSB filter. Since I was half way I decide to make the
extended TX mod.

I was using a "regular" soldering iron. After two attempts, the
first one did not work maybe because my poor soldering, I was able to
make the modification but whet I connect the antennas I notice I have
a very attenuated reception on all bands. I guess I put to much heat
on the jumpers.

This attenuation is when using USB, LSB, CW, AM. But not when using
FM, WFM or Packet in which the radio is receiving as usual.

One very strange thing is that if I am on 1.799 the reception in any
mode is fine but as soon as I go to 1.800 (160 meters)the RX is
immediately attenuated.

I have try the jumpers as several MODs mentioned, as well as infinite
number of resets but the reception is still attenuated.

Right now I have the original jumper setting.

Any ideas or suggestions?

Plans for Field Day?

Glyph
 

How many you guys (and gals) taking your 817 out somewhere interesting for Field Day here in the U.S.?

I'm biking out to a state park in California's hot country with a solar panel, a 5-ah battery, two different types of wire antennas, and if they tell me there isn't much in the way of trees, a 20' pole.

Should arrive around noon, set up a tent, stay overnight, etc. I'm tempted to take along an extra 7-ah battery, but that's a lot of extra weight to carry for many miles on a bike. Will operate SSB as much as possible.

My hope is that a club isn't setting up in the park (also) with high-power rigs.

Like to hear back from those of you who go. Scores, etc. Good luck!

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.

BNC Adapter

Radio Shack sells a male to female Right angle BNC adapter for $3.99

that works well with the 817. Part # 278-116b.

I believe someone on the list was looking for one.
Right Angle Power Connectors

[email protected]
 

A while back someone posted that Mouser had a right angle plug for
the external power connection. The barrel of this plug is too short
to work on the 817. The plug is made by DGS and carries a Mouser
number of 171-3221. The barrel must be at least 10MM long to work on
the 817.

if you don't like green you may have to spend 2$ for spray paint - I screw
10/15/17/20 meter Hustler resonators on top and don't have any trouble
hitting resonance with a three foot mast. It won't get ya on 40, but I'd
